Hsoumii Posted March 28, 2017 Share Posted March 28, 2017 Hello guys I'm making a platformer game, I struggled with making collision between the player and objects created in tiled but after that I got it working with a function I created, however, when I make the rectangle rotated in tiled, in the game it comes out away from its position, take a look: this is on tiled in the game it comes out like this here is my code, createCollisionObjects is where the magic happens var game = new Phaser.Game(70 * 10, 70 * 7, Phaser.AUTO, 'game', { preload: preload, create: create, update: update, render: render }); function preload() { // tilemap game.load.tilemap( 'map', 'assets/tilemaps/maps/lvl-1.json', null, Phaser.Tilemap.TILED_JSON ); // tilemap images game.load.image('new', 'assets/tilemaps/tiles/new.png'); game.load.image('sheet', 'assets/tilemaps/tiles/sheet.png'); game.load.image('s9af', 'assets/tilemaps/tiles/s9af.png'); // player spritesheet game.load.atlasJSONHash( 'player', 'assets/spritesheets/player_walk.png', 'assets/spritesheets/player_walk.json' ); } /* * GLOBAL VARIABLES */ var map; var player; var playerSpeed = 400; var jumpTimer = 0; function create() { game.physics.startSystem(Phaser.Physics.P2JS); game.physics.p2.setBoundsToWorld(true, true, true, true, false); game.physics.p2.gravity.y = 300; game.physics.p2.restitution = 0; game.stage.backgroundColor = '#ffffff'; map = createMap().map; var start = map.objects.objective[0]; player = createPlayer({x: start.x, y: start.y}); cursors = game.input.keyboard.createCursorKeys(); } function update() { player.body.setZeroVelocity(); if (cursors.up.isDown && game.time.now > jumpTimer && checkIfCanJump()) { player.body.velocity.y = 600; jumpTimer = game.time.now + 750; } if(cursors.left.isDown) { player.body.velocity.x = -playerSpeed; player.animations.play('walk'); } else if (cursors.right.isDown) { player.body.velocity.x = playerSpeed; player.animations.play('walk'); } else { player.body.velocity.x = 0; player.animations.stop(); player.frame = 0; } game.camera.follow(player); } function render() { } function createMap() { var m, g, f, b, c; m = game.add.tilemap('map'); var mWidth = m.widthInPixels; var mHeight = m.heightInPixels; game.world.setBounds(0, 0, mWidth, mHeight); m.addTilesetImage('sheet', 'sheet'); m.addTilesetImage('new', 'new'); m.addTilesetImage('s9af', 's9af'); g = m.createLayer('ground'); f = m.createLayer('fringe'); b = m.createLayer('background'); g.resizeWorld(); f.resizeWorld(); b.resizeWorld(); createCollisionObject(m.objects.objects); return { map: m, ground: g, fringe: f }; } function createPlayer(pos) { var p = game.add.sprite(pos.x, pos.y, 'player', 'Symbol 2 instance 10000'); //p.scale.setTo(0.4, 0.4); game.physics.p2.enable(p); p.body.setZeroDamping(); p.body.fixedRotation = true; p.body.x+=p.width/2; p.body.y+=p.height/2; // animation p.animations.add( 'walk', Phaser.Animation.generateFrameNames('Symbol 2 instance 1000', 0, 7, '', 1), 10, true, false); //p.animations.play('walk-left'); return p; } function createCollisionObject(objects) { if (objects) { for(var i=0; i < objects.length; i++) { var p2 = game.physics.p2; var obj = objects[i]; var sprite = game.add.sprite(obj.x, obj.y, null); sprite.width = obj.width; sprite.height = obj.height; sprite.angle = obj.rotation; game.physics.p2.enable(sprite, false); sprite.body.x = sprite.x + sprite.width / 2; sprite.body.y = sprite.y + sprite.height / 2; sprite.body.rotation = obj.rotation; sprite.body.static = true; sprite.body.debug = true; } } } function checkIfCanJump() { var yAxis = p2.vec2.fromValues(0, 1); var result = false; for (var i = 0; i < game.physics.p2.world.narrowphase.contactEquations.length; i++) { var c = game.physics.p2.world.narrowphase.contactEquations[i]; if (c.bodyA === player.body.data || c.bodyB === player.body.data) { var d = p2.vec2.dot(c.normalA, yAxis); // Normal dot Y-axis if (c.bodyA === player.body.data) d *= -1; if (d > 0.5) result = true; } } return result; } Link to comment Share on other sites More sharing options...
