currently focused on dissecting the `TypeError` related to the missing `BodyVelocity` property. My hypothesis is that a script is attempting to access this property on an undefined instance within the game's Lua VM, leading to the error message. I'm exploring where that instance might be initialized, or if it isn't, and what might be the cause.\n\n\n**Investigating Child Access**\n\nI'm now zeroing in on how children are accessed. The `BodyVelocity` error likely arises from code that assumes children can be directly accessed as properties via their names, like `part.BodyVelocity`. This mirrors legacy Roblox behavior. The crucial point is the `LuaInstance` mock *doesn't* automatically expose children.\n\nI also see a `TypeError: Cannot read properties of undefined (reading 'clone')`. This could indicate an attempt to call `clone()` on something that isn't a `LuaInstance`, or something is missing.\n\n\n**Pinpointing Null Properties**\n\nI'm now investigating a \"Cannot read properties of null\" error, specifically \"reading 'Engine'.\" My current hypothesis leans towards a scenario where an attempt is made to access a child property, like \"Engine,\" on an object that's unfortunately null. This suggests that the code is trying to find a child that doesn't actually exist in the object tree.\n\n\n**Examining Instance Properties**\n\nI'm now focusing on how `CFrame.Angles` is accessed in Roblox Lua versus how it's handled here, finding inconsistencies. Also, I'm examining a `TypeError` due to an attempt to set `Value` on an undefined object, likely a `StringValue` or similar. I am further refining the `LuaInstance` mock by leveraging the existing proxy structure in `transpileAndRun` to intercept property accesses. This should allow child objects to be accessed using the dot notation (`parent.ChildName`).\n\n\n**Implementing Proxy Structure**\n\nI'm now incorporating a proxy structure to wrap `LuaInstance` creation. This will provide a more Roblox-like experience. Specifically, the constructor now returns a proxy. This is going to intercept property accesses, allowing child objects to be accessed using dot notation, e.g., `workspace.Part`.\n\n\n**Testing Class Constructors**\n\nI'm now focused on class constructors. I've confirmed they function in JavaScript. I'm investigating how extending `LuaInstance`, such as with `LuaHumanoid`, impacts the proxy behavior. It appears `super()` returns the Proxy and subclasses can add properties. However, there may be some issues with `this` in the subclass with a proxy.\nI am running tests to confirm that returning a proxy from the base class constructor works well for subclasses.\n```javascript\nexport class LuaInstance {\n constructor(className, name) {\n this.className = className;\n this.Name = name;\n this.Parent = null;\n this._children = [];\n this.ChildAdded = new LuaSignal();\n this.Changed = new LuaSignal();\n this.Touched = new LuaSignal();\n this.Velocity = { x:0, y:0, z:0 };\n this.Position = { x:0, y:0, z:0 };\n this.CFrame = { x:0, y:0, z:0 };\n \n return new Proxy(this, {\n get\n```\n\n\n**Refining Property Access**\n\nI'm now refining property access, implementing a `set` trap in the proxy to handle custom property assignments, like `part.CustomProperty = value`. I'm also ensuring that `Instance.new(\"BodyVelocity\")` is properly handled. I've re-examined the mock `LuaVM.transpileAndRun`, verifying the Vector3 and CFrame constructors.\n\n\n**Addressing Instance Creation**\n\nI'm now zeroing in on handling `Instance.new(\"BodyVelocity\")` and similar calls. It seems that creating instances should use `Instance.new`, not the class's constructor. The `BodyVelocity` error likely arises from the script attempting to directly access the `BodyVelocity` property on an undefined `part`. I'm checking that parents are set correctly, specifically for scripts. The parser seems correct, with proper parent assignment. I'm focusing on the interaction of the parent property.\n\n\n**Preserving Script Parents**\n\nI'm now focused on preserving the parent property when parsing scripts from the .rbxl file. I realized the script's `Parent` wasn't being preserved, leading to potential issues with script execution. Specifically, I'm integrating logic to accurately identify and set the parent of each script object during parsing, ensuring it's correctly linked in the object tree. Currently, I am capturing `serverScripts[name + \"_\" + Math.random()] = { source, parentClassName: ??? }`, and working on associating that `parentClassName` with the script.\n\n\n**Fixing Script Parents**\n\nI'm now integrating parent association for scripts to fix the `BodyVelocity` issue. The .rbxl parsing logic wasn't correctly associating a script's parent with the object tree, leading to the `script.Parent` resolving to a generic `Workspace` mock instead of the expected `Part`. I am updating the parsing process to ensure the correct parent of each script object is properly assigned, resolving the `script.Parent.BodyVelocity` problem. I'm focusing on preserving the correct `parentClassName` from the file.\n\n\n**Connecting Object References**\n\nI'm now investigating a \"Cannot read properties of undefined (reading 'BodyVelocity')\" error, which means the object before `.BodyVelocity` is undefined, likely `part`. I'm tracing back to the root cause. This reminds me that I need to ensure `parseRBXL` populates the `Workspace` mock with instances. Currently, `ServerScripts` run in a completely detached dummy Lua environment!\n\n\n**Populating Workspace Children**\n\nI've realized the crucial need to populate the `Workspace` with parsed instances to fix \"Cannot read properties of undefined\". Currently, the `Workspace` is a bare-bones mock lacking any children. This means the `ServerScripts` run in a completely detached environment. I'm now focusing on creating `LuaInstance` objects mirroring the RBXL hierarchy, at least for relevant types like `Part` and `Model`, and linking them to a DOM-like structure. My immediate task is to iterate through the parsed `` elements and instantiate corresponding `LuaInstance` objects, properly parenting them under the `Workspace`.\n\n\n**Constructing Lua Object Tree**\n\nI'm now implementing the crucial `buildLuaTree` function within `parseRBXL` to create a hierarchical structure of `LuaInstance` objects mirroring the RBXL file's contents. I'm focusing on parsing `` tags recursively, and associating the `ServerScript`'s actual instance into the VM, with appropriate `Parent` properties. I am also working on linking each parsed instance with its children, ensuring the integrity of the object tree.\n\n\n**Building Object Properties**\n\nI'm now extracting specific properties from the parsed `` tags, focusing on populating the `LuaInstance` objects. I'm handling boolean, float, and integer values, ensuring these properties are accurately set on the `luaInst` object. This is a crucial step for accurately representing the RBXL file's data within the Lua environment.\n\n\n**Parsing Vector3 Values**\n\nI'm now zeroing in on parsing Vector3 values from the XML data. I'm focusing on extracting the X, Y, and Z components from the `` tags and setting them as properties on the `LuaInstance` objects. I'm also implementing the string extraction from XML files. This is important to ensure the correct values are properly loaded into the `LuaInstance` object.\n\n\n**Mapping XML to LuaInstances**\n\nI'm now focusing on mapping XML `` nodes to `LuaInstance` objects. I've realized I can build the Lua object tree *first* and then link that with the physics data! I can use a hierarchical pass within `parseRBXL` to maintain parent relationships.\nI am updating the existing parsing to handle the object tree structure correctly.\n\n\n**Constructing Lua Object Tree**\n\nI'm now integrating the `buildLuaTree` function to construct a complete Lua object hierarchy directly from the parsed XML. This includes instantiating and properly parenting `LuaInstance` objects based on the XML structure. This hierarchical pass within `parseRBXL` ensures a faithful representation of the RBXL file's object tree within the Lua environment. I am creating a `xmlToLua` map to map the XML item to the `LuaInstance` object, too.\n\n\n**Refining Tree Construction**\n\nI'm now refining the `buildLuaTree` function to handle complex property assignments during object tree construction. I am going to properly handle boolean, float, and integer values. I've re-examined the code to handle `Vector3` properties, including string parsing. I am making use of a `xmlToLua` to map the XML item to the `LuaInstance` object, too.\n\n\n**Refining Value Parsing**\n\nI'm now refining how I extract numerical properties within the Lua object tree. Specifically, I'm working on robustly parsing `Vector3` and `CoordinateFrame` values from the XML. I'm ensuring all three components, X, Y, and Z, are extracted correctly from the XML and assigned as properties to the Lua instance.\n\n\n**Connecting Physics Interactions**\n\nI'm now integrating physics. I am connecting `luaInst.physicsPart` after the object tree is created. I've linked the `physicsPart` to the `luaInst` object. This is important to allow the game to access and modify the physics parts, which means that I can update assembly velocity.\n\n\n**Integrating Physics Interactions**\n\nI'm now integrating physics interaction between the Lua environment and the physics engine! I've connected `physicsPart` to `LuaInst`. This integration enables the physics engine to interact with the game. Specifically, I'm now implementing the `Velocity` property, which allows modification from the Lua environment to update physics part assembly velocity. I'm also planning to implement the `.CFrame` property!\n\n\n**Implementing Touch Events**\n\nI'm now implementing the `Touched` event for parts, triggered when objects intersect in the physics simulation. This will be triggered within the physics engine upon intersection, allowing parts to respond to contact, like a player stepping on something. I am also implementing a `Touched` event similar to `Part.Touched:connect(function(hit) ... )`.\n\n\n**Implementing Touch Events**\n\nI'm now implementing the `Touched` event. I'm focusing on ensuring parts, particularly static AABBs, trigger the event upon intersection within the physics simulation. This involves adding `luaInst` to static AABBs. My focus is triggering the `Touched` event for parts when objects intersect, similar to `Part.Touched:connect(function(hit) ... )`. I'm also ensuring the firing interval is correctly managed to avoid spam.\n\n\n**Implementing Player Touch Events**\n\nI'm now integrating player touch events within the physics engine. I'm focusing on making sure `Touched` events fire correctly when the player character interacts with static objects. I've implemented a mechanism in the main loop to check for overlaps between the player's AABB and static AABBs. I'm also ensuring the firing interval is correctly managed to avoid spam.\n\n\n**Refining Property Proxy**\n\nI'm now refining the `LuaInstance`'s property proxy. I'm focusing on improved handling of `get` traps within the `LuaInstance` class. This is going to return child objects by name, resolving issues with dot notation access and allowing property setting.\n\n\n**Enhancing Instance Properties**\n\nI'm now implementing getters and setters for `Velocity`, `CFrame`, and `Position` properties within `LuaInstance`. These will accurately reflect and control the physics part's state. I'm focusing on ensuring changes in the Lua environment are reflected in the physics simulation. This will allow modification from Lua scripts to update the assembly velocity and position in the physics environment.\n\n\n**Integrating Physics Access**\n\nI'm now integrating direct Lua access to physics properties. I've implemented getters and setters for `Velocity` and `Position` within `LuaInstance`. This allows modification of the physics part's state directly from Lua scripts. I'm ensuring changes are reflected correctly in the physics simulation.\n\n\n**Implementing BodyVelocity Physics**\n\nI'm now integrating `BodyVelocity` into the physics simulation. I've realized `BodyVelocity` is often used to control part movement. Therefore, I can easily implement it by checking for `BodyVelocity` children within the physics update. If a `BodyVelocity` child exists on a part, I will read its `Velocity` property, which will be applied to the assembly velocity. I'm focusing on ensuring this integration is seamless.\n\n\n**Implementing BodyVelocity Properties**\n\nI'm now integrating the `BodyVelocity`'s lowercase `velocity` property into the physics engine update, specifically within the dynamic update loop. I've corrected the case, focusing on the lowercase `velocity` property for `BodyVelocity`, and now also adding `BodyPosition` support. I'm ensuring this integration is correct in physics calculations.\n\n\n**Refining BodyPosition Physics**\n\nI'm now integrating `BodyPosition` support. Within the dynamic update loop, I'm checking if a `BodyPosition` child exists and calculating its effect on the assembly's position. This ensures the part is moved towards the target position. I am also making sure that `hasBodyPosition` is handled.\n\n\n**Refactoring Physics Integrations**\n\nI'm now integrating `BodyPosition` physics support, using new properties. I am working on the case for `CFrame.Angles` and `CFrame.fromEulerAnglesXYZ` methods. Furthermore, I am updating the execution logic in `main.js` and `rbxl-parser.js`. I'm rebuilding the Lua object tree and then associating the scripts with `luaInst` objects. Finally, I'm integrating the `BodyVelocity` lowercase velocity property.\n\n\n**Refining Script Execution**\n\nI'm now focusing on how the scripts are executed, realizing that `luaNode.Source` needs an environment to run, so I'm investigating how this is handled in `main.js`. Previously, `serverScripts` weren't connected to the instance. I am now passing the correct instance `scriptData.luaInst` to the Lua VM! I'm now making sure `transpileAndRun` can correctly execute the instance.\n\n\n**Refining Script Environments**\n\nI am now focusing on refining the environment passed to `transpileAndRun` to ensure correct script execution. I am building a dedicated environment for each script to include the `game`, `workspace`, and `script` globals, using the constructed mocks. This ensures the script has the correct context, enabling proper execution, while allowing the program to continue, such as passing `luaInst` to `transpileAndRun`.\n\n\n**Defining Script Environment**\n\nI'm now focusing on defining a comprehensive execution environment for scripts within the Lua VM. I'm structuring a global environment for each script that includes crucial properties like `game`, `workspace`, and `script`, utilizing the appropriate mocks. This comprehensive approach addresses the previous execution context shortcomings, guaranteeing correct script execution and maintaining proper program flow.\n\n\n**Adapting Script Environments**\n\nI'm now adapting how script environments work within `transpileAndRun`. I've added logic to handle the `character.js` and dedicated-environment cases for compatibility. The updated `transpileAndRun` function now supports receiving either a full environment or the `workspaceMock` and `scriptMock`. It then constructs the proper environment using mocks, which allows legacy integrations while supporting the creation of script environments!\n\n\n**Refining Execution Context**\n\nI'm now revising how scripts' execution context is established, ensuring that `transpileAndRun` can correctly execute. I'm focusing on the environmental setup. I've confirmed `transpileAndRun` now handles both an environment and the `workspaceMock`/`scriptMock` structure. I am adapting the execution to properly pass the `luaInst` to `transpileAndRun`.\n\n\n**Expanding Script Environment**\n\nI'm now expanding the script environment, incorporating crucial service mocks to enhance functionality. I've added mocks for `RunService`, `Instance`, `Vector3`, `CFrame`, `BrickColor`, `math`, `tick`, `delay`, `spawn`, `wait`, and `print`. This comprehensive setup ensures scripts can utilize a wider range of Roblox APIs.\n\n\n**Enhancing Global Scripting**\n\nI'm now enhancing script capabilities by adding mocks for core Roblox services. I've integrated `RunService`, `Instance`, `Vector3`, `CFrame`, `BrickColor`, `math`, `tick`, `delay`, `spawn`, `wait`, and `print`. This comprehensive environment setup expands scripting functionality.\n\n\n**Expanding Service Mocks**\n\nI'm now expanding mocks within the script environment to improve code execution, particularly within a player context. I've integrated mocks for `Players`, which will include a `GetPlayerFromCharacter` function to represent character state, and `service`, which includes a `RunService` with `Stepped` signal, and `GetService` for a similar setup. This is a good way to expand the scripting functionality and mimic player characteristics within scripts.\n\n\n\n**Expanding Script Environment**\n\nI'm now expanding the script environment, focusing on adding a mock for `Players`, including a `GetPlayerFromCharacter` function to represent character state, which allows the use of Player objects within scripts. I am also implementing a mock for `service`, which includes a `RunService` with `Stepped` signal, and `GetService` for a similar setup, to support player-specific scripting functionality.\n\n\n**Implementing Player Integration**\n\nI'm now integrating player mechanics within the scripting environment. I'm focusing on the `Players` service mock, including implementing the `GetPlayerFromCharacter` function. I'm also ensuring the character state is properly represented in player-related scripts. My approach enhances scripting capabilities within a player context, enabling a more realistic simulation.\n\n\n**Integrating Player Simulation**\n\nI am now implementing the player within the simulation by integrating the `Players` service. I'm focusing on ensuring player state is accurately reflected and I'm updating my `GetPlayerFromCharacter` implementation. This integration improves the scripting capabilities and realistic game simulation.\n\n\n**Implementing CFrame Properties**\n\nI'm now integrating `CFrame` property setters into `LuaInstance`, mirroring Roblox behavior. The `CFrame` getter now returns a structured object representing the current position. The corresponding setter handles position updates for the associated physics part. This ensures seamless synchronization of position data between Lua scripts and the physics simulation.\n\n\n**Expanding Lua Properties**\n\nI'm now implementing the properties for the LuaInstances, focusing on providing structure like the Lua environment in Roblox, and adding support for essential properties like `Name` and `Parent`. I'm going to look into `CFrame` properties. I am working on integrating the necessary functionality.\n\n\n**Enhancing Game Objects**\n\nI'm now implementing `Touched` for all instances, triggered on intersection. I am focusing on adding `luaInst` to static AABBs. My attention is on triggering the `Touched` event for parts, which is similar to `Part.Touched:connect(function(hit) ... )`.\n\n\n**Importing LuaInstance Fix**\n\nI've fixed an import issue. I realized I forgot to include `LuaInstance` in `rbxl-parser.js`. I've now added it, addressing the missing object error.\n\n\n**Integrating Touch Events**\n\nI'm now implementing the essential `Touched` event for all instances, triggered upon any intersection within the physics simulation. This involves incorporating `luaInst` into static AABBs. My priority is mimicking the `Part.Touched:connect(function(hit) ... )` functionality to enable parts to respond to contact within the game.\n\n\n**Constructing Lua Object Tree**\n\nI'm now initializing the `serverScripts` object and the Lua workspace. The goal is to build the Lua instance hierarchy, and now I'm making sure to clear the physics world before I do any population.\n\n\n**Constructing Lua Object Tree**\n\nI'm now iterating through the XML nodes to populate `xmlToLua` and build the object hierarchy. I am focusing on iterating through the children of the `` node, which represent the game objects, and then I am linking the parsed XML nodes with the corresponding `LuaInstance` objects.\n\n\n**Parsing Property Values**\n\nI'm now focusing on the value parsing from the XML, making sure Boolean, float, and integer values are correctly converted and set in the Lua object tree. Also, I am implementing Vector3 properties from the XML data into the Lua instances, extracting X, Y, and Z. I'm verifying the parsing and assignment of properties to maintain data accuracy.\n\n\n**Parsing CoordinateFrame Values**\n\nI'm now focusing on parsing `CoordinateFrame` and extracting properties to ensure correct value extraction. Currently, I am extracting X, Y, and Z properties, and ensuring correct value extraction. I am also implementing support for `CoordinateFrame` to ensure proper positioning within the Lua object tree.\n\n\n**Refining XML Parsing**\n\nI'm now integrating properties and processing `CoordinateFrame` values from XML, extracting position components. I'm focusing on parsing numeric values. My focus is on robustly processing float values. I am also working on enhancing the efficiency of extracting attributes.\n\n\n\n**Refining Parsing Integration**\n\nI'm now integrating the parsing logic with the Lua object construction. I'm focusing on ensuring data from the XML structure gets correctly mapped to Lua `Instance` objects. I am prioritizing a hierarchical approach within `parseRBXL` to maintain relationships. I am ensuring that the extracted properties, including boolean, float, and integer values are accurately set within the Lua `Instance` objects.\n\n\n**Connecting Physics Parts**\n\nI'm now focusing on connecting `luaInst` objects with their corresponding physics parts after the Lua object tree is built. This is essential for enabling interactions and reflecting changes in the physics simulation. I'm prioritizing the integration of physical attributes, such as position, to ensure accurate synchronization between the Lua world and the physics engine.\n\n\n**Refining Physical Bounds**\n\nI'm now integrating the physics world interaction. I'm focusing on ensuring physical bounds are accurately applied to standard blocks and wedges during parsing. I am making use of a `THREE.Box3` to apply an approximation AABB, which then sets the physical properties for dynamic and static parts. I am ensuring correct placement in the world object.\n\n\n**Integrating Script Execution**\n\nI'm now integrating script execution with the Lua workspace. The updated `main.js` will pass the `workspaceLua` object and the `luaInst` object. I am working on integrating the necessary elements to ensure scripts are executed correctly. I'm focusing on making sure scripts run correctly in the environment.\n\n\n**Refining Script Execution**\n\nI'm now revising script execution to directly pass the `workspaceLua` object and the associated `luaInst` object from the parsed RBXL data to the Lua VM. This addresses prior deficiencies in environment context and enhances script execution reliability by ensuring proper object relationships are maintained. I'm focusing on direct integration to run the scripts within `transpileAndRun`.\n\n\n**Connecting Player Events**\n\nI'm now integrating player `Touched` events within `main.js`. I'm going to trigger `Touched` events for players colliding with static AABBs in `main.js`, now that I have the player character and all the static objects from the Lua world set up! This ensures accurate player-object interaction. I will trigger events for players in collision to provide a seamless interaction experience.\n\n\n**Implementing Player Physics**\n\nI'm now integrating player character physics within the simulation's update loop, specifically focusing on handling player collisions. I am implementing collision detection by looping through all AABBs and checking for intersections between the player's AABB and the static AABBs. My priority is triggering `Touched` events for the player when collisions occur, reflecting realistic object interaction within the game.\n\n\n**Integrating Player Physics**\n\nI'm now implementing collision detection in the main game loop, looping through AABBs.
