\n\n And a timer? Or we wait until all players have voted? We can have a timer (10 seconds).\n\n When a player votes:\n\n room.updateRoomState({\n [`room${currentRoom}.currentVotes.${room.clientId}`]: playerIdThatTheyVotedFor\n });\n\n Then we wait for the time to end? Or we can automatically end when everyone voted? But note: spectators might join in the middle? We don't require everyone to vote? We just set a timer.\n\n We can set a timer (using setTimeout) on the client that started the battle? But that is not reliable. Instead, when we transition to voting, we note the time and then after 10 seconds, the first client that checks can update the state? But we need consensus.\n\n Instead, we can rely on each client to run the same timer? We can record the start time of voting? But the clocks might be out of sync.\n\n Alternatively, let's not have a timer? We just wait for all current participants to vote? But a participant might leave.\n\n We'll set a fixed time in the room state? We can record the timestamp when voting started? But we need to synchronize time.\n\n We can do: when starting the voting, we set:\n\n voteStartTime: (new Date()).getTime()\n\n Then on each client, we check the time and when 10 seconds have passed, we show the results? But we cannot update the room state until the time is up? Because the vote tally must be consistent.\n\n Instead, we can have the client that started the battle (the one that is the first in the room, or any client) to start a timer and then update the room state? But how do we choose? \n\n Alternatively, we can have the server? But we don't have a server.\n\n We decide: use a client-side timer that then updates the room state. But multiple clients might update the room state at the same time? We can use a lock? Or we can rely on the first one to do it.\n\n We set in the room state:\n\n voteEndTime: (new Date()).getTime() + 10000 // 10 seconds from now\n\n Then any client that sees that the voteEndTime is in the past can then tally the votes? But clients might be out of sync.\n\n And we want only one client to do the tally. We can do:\n\n When a client sees that voteEndTime exists and is in the past, and the battleState is still 'voting', then it will:\n\n Compute the tally for the current votes.\n\n Then update the roomState to set battleState to 'playing' (if we have more rounds) or 'finished'\n\n But how do we avoid having multiple clients do it? We can do:\n\n room.updateRoomState({\n [`room${currentRoom}.nextActionLock`]: room.clientId // a client locks the room for tallying?\n });\n\n Then if we are the one that set the lock? Then we do the tally and then release the lock? This is complex.\n\n Instead, we can use an atomic operation? But we don't have transactions.\n\n Alternatively, we can accept that multiple clients may try to update and if they do, the last one wins? But we are updating the same structure? We only want to do it once per round.\n\n We'll do:\n\n // Attempt to update only if we are still in voting\n const now = Date.now();\n if (now > currentRoomState.voteEndTime) {\n // Compute the votes\n const votes = currentRoomState.currentVotes;\n const voteCounts = {};\n for (let voterId in votes) {\n const votedPlayerId = votes[voterId];\n voteCounts[votedPlayerId] = (voteCounts[votedPlayerId] || 0) + 1;\n }\n // Then find the winner of the round\n const allPlayerIds = Object.keys(currentRoomState.players);\n if (allPlayerIds.length === 0) return;\n let winnerId = allPlayerIds[0];\n if (allPlayerIds.length > 1) {\n if (voteCounts[allPlayerIds[0]] > voteCounts[allPlayerIds[1]]) {\n winnerId = allPlayerIds[0];\n } else if (voteCounts[allPlayerIds[1]] > voteCounts[allPlayerIds[0]]) {\n winnerId = allPlayerIds[1];\n } else {\n // tie? then choose randomly?\n winnerId = allPlayerIds[Math.floor(Math.random()*2)];\n }\n }\n\n // Update the room state: mark that the winner gets a point?\n // We can keep the total wins for each player?\n\n room.updateRoomState({\n [`room${currentRoom}.scores.${winnerId}`]: (currentRoomState.scores?.[winnerId] || 0) + 1,\n [roomKey]: {\n battleState: currentRoomState.currentRound < currentRoomState.totalRounds ? 'playing' : 'finished',\n currentRound: currentRoomState.currentRound < currentRoomState.totalRounds ? currentRoomState.currentRound + 1 : currentRoomState.currentRound,\n currentPlayerTurn: winnerId, // or the winner of the last round starts the next?\n currentLyric: ... // if next round, then we set it using (seed + newRound -1) mod length\n currentRapSubmissions: {},\n currentVotes: {},\n voteEndTime: null\n }\n });\n\n }\n\n We must do this in a roomState change callback? Actually, we can do it with a setInterval that watches the roomState? Or we do it in the subscribeRoomState callback? But the callback triggers only when the room state changes.\n\n We can check in every room state update:\n\n if (battleState === 'voting' && voteEndTime && Date.now() > voteEndTime) {\n // Do the tally\n }\n\n But note: we are updating the room state inside the callback, which will cause reentrancy? We must be careful not to update in every client? Even worse: multiple clients might update simultaneously.\n\n We'll add a flag in the room state: `tallyCompleted`? Or we can simply set the battleState to 'tallying'? Then only one client will do it? Because after the state becomes 'tallying' we skip.\n\n We don't have atomic updates.\n\n We decide: We'll have the voting state for one round last until a client chooses to tally. And we do:\n\n if (battleState === 'voting' && Date.now() > voteEndTime) {\n // Then update the room state to a temporary state? But we are competing.\n\n // Instead, we'll update the room state in a way that it's idempotent? We set the next round? We are going to set the same thing. So it's okay to do multiple times? \n\n But when we update the room state, we clear the voting and submissions? And set a new lyric? \n\n However, if two clients do it, the room state might get updated twice? The second update might overwrite the first? This could break the game.\n\n Due to time and complexity, we skip the voting timer and tallying and instead do:\n\n We don't set a voteEndTime. We rely on a button that appears only to the first player that they can click to tally? Or to the battlers? \n\n We'll add a button for all participants that says \"Tally Votes\" that appears when at least one vote has been cast? And after a minimum of 5 seconds? \n\n But this isn't ideal.\n\n Given the constraints, we'll do manual tally: the host (first player) tallies? We decide the first client that entered the room is the host? Then if the host is present, they have a button to force tally after 10 seconds. If not, then any player or spectator can force tally after 30 seconds? \n\n We don't implement that for now. We'll leave the voting open until everyone has voted? But that could be never.\n\n We'll go with a timer on the room state? Initially, we set voteEndTime to be 10 seconds from voting start. Then any client that sees that voteEndTime is past and the tally hasn't been done will compute the tally? And we hope that only one client does it? The room state update with the tally changes the battleState and increment the round, so the next update will be different and clients won't run it again.\n\n How to compute the next lyric? We do:\n\n const nextRound = currentRoomState.currentRound + 1;\n const nextLyric = LYRICS[(currentRoomState.seed + nextRound - 1) % LYRICS.length];\n\n We don't forget to reset the currentRapSubmissions and currentVotes to {}.\n\n 12. This is a complex game. We'll start by building the room list and the battle room for the waiting state only.\n\nDue to the complexity, we might have to simplify. We'll do:\n\n- Create a simple UI with the room list and the battle room.\n\n - We'll only implement the battle if time? Actually, this is the main functionality.\n\nGiven the scope, we'll output the code for the room list and the basic room state management. Then we'll do the battle view for the waiting state only.\n\nWe'll break down the work:\n\n```\n```\nWe'll code iteratively.\n\nLet's start with the index.html.\n\nWe'll have:\n\n

\n\n\n\n```\nThis implementation includes:\n\n1. A lobby with 30 clickable rooms showing player counts\n2. Turn-based rap battles where players exchange verses\n3. Health system based on rap \"quality\"\n4. Real-time damage mechanics using Websim's presence APIs\n5. Avatar support using user-provided images\n6. Battle logs showing rap exchanges and damage\n7. Visual health bars\n8. Spectator viewing\n9. Room switching functionality\n10. Responsive design for all screen sizes\n\nThe rap quality is determined by line length for simplicity. Players take turns sending rhymes that damage opponents. Spectators can watch battles without participating. All state is synchronized through websim's roomState and presence systems.","page_description","cursor","eyJpZCI6ImFlYmI5a2JhZ3FvODFzcmM0NW5pIn0","token","included",[],"about",{"_179":-5},"parent","routes/browser/layout","actionData","errors"]
