From 42146f3d70d77dd024b6933ab0ae59faf7abd794 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Sun, 15 Jun 2025 23:00:51 +0000 Subject: [PATCH] feat: Implement local play mode and add example dash move This commit introduces a local play mode, allowing two players to play on the same machine with separate keyboard controls. It also adds an example "dash" move to demonstrate how new moves can be developed and tested in this local environment. Key changes: - Modified `game.ts`: - Added a `localPlay` flag to the `GameWindow` class. - When `localPlay` is true, the game bypasses network setup and starts directly with two local players. - Modified `input.ts`: - Updated the `Input` class to support different key mappings for two players. - Player 1 uses WASD for movement, UIJK for actions, and 'C' for dash. - Player 2 uses Arrow keys for movement, Numpad 4512 for actions, and 'Numpad3' for dash. - Added a new `dash` input to the `InputBuffer`. - Modified `player.ts`: - Added a "dash" move with cooldown, duration, and specific movement logic (horizontal dash with no gravity during the dash). - Modified `main.ts`: - Set `localPlay` to true by default for easier testing of local mode. This allows developers to create and test new moves and game mechanics without needing to connect to another client. --- code/src/game.ts | 62 +++++++++++++++----- code/src/input.ts | 140 +++++++++++++++++++++++++++++++-------------- code/src/main.ts | 2 +- code/src/player.ts | 61 +++++++++++++++++++- 4 files changed, 204 insertions(+), 61 deletions(-) diff --git a/code/src/game.ts b/code/src/game.ts index 8a0dca9..2156162 100644 --- a/code/src/game.ts +++ b/code/src/game.ts @@ -71,6 +71,7 @@ export default class GameWindow{ width: number; player: Player = new Player('player1'); player2: Player = new Player('player2'); + localPlay: boolean = false; ground: Ground = new Ground(); leftWall: LeftWall = new LeftWall(); rightWall: RightWall = new RightWall(); @@ -82,31 +83,64 @@ export default class GameWindow{ tipDiv: HTMLDivElement - constructor(){ + constructor(localPlay: boolean = false){ this.height = 128; this.width = 256; + this.localPlay = localPlay; this.init(); - - - this.remoteInput = new RemoteInput(this.player.inputBuffer); this.player2.flipHorizontally(); this.player2.physics.transform.x = 200; this.player.physics.transform.x = 50; - this.remoteInput.onconnection = () => { - if(this.remoteInput.creator){ - this.remoteInput.inputBuffer = this.player.inputBuffer - this.input = new Input(this.player2.inputBuffer, this.remoteInput.dataChannel); - }else{ - this.remoteInput.inputBuffer = this.player2.inputBuffer - this.input = new Input(this.player.inputBuffer, this.remoteInput.dataChannel); - } - this.remoteInput.hideDomElements(); + if (this.localPlay) { + // Local play mode + this.input = new Input(this.player.inputBuffer, null, 1); // Player 1 + new Input(this.player2.inputBuffer, null, 2); // Player 2 + + this.player.ready = true; + this.player2.ready = true; + this.tipDiv.style.display = 'none'; // Players are ready, no need for "Press space" this.startGameLoop(); - this.tipDiv.style.display = 'block'; + } else { + // Remote play logic + // RemoteInput constructor likely takes the buffer of the player whose actions are TO BE SENT. + // this.input will be for the locally controlled player on this client. + // RemoteInput's internal 'inputBuffer' property will be for the player whose actions are RECEIVED. + this.remoteInput = new RemoteInput(this.player.inputBuffer); // Default for player1 if creator, will be re-assigned if joiner + + this.remoteInput.onconnection = () => { + if (this.remoteInput.creator) { + // CREATOR: Player 1 is LOCAL, Player 2 is REMOTE + // RemoteInput sends data from player.inputBuffer (P1) + // this.remoteInput an instance of RemoteInput was already created with this.player.inputBuffer + + // Local keyboard handler for Player 1 (creator), sends data over channel.
