Hello, I have a problem about arcard, I want to create a game to pile up blocks to make a building like a tower higher. when the second block fall onto the first one, everything is OK, but when the third one(or the fourth, fifth,etc) come, the block began to overlap and fall down. could anyone help me? thanks and very appreciate! the relative code is in 'playstate' object. var Game = (function() { var game; var floorBlocks; var rope; var ropeTween; var stick; var background; var score = 0; var scoreText; var creatingItem; var bottomBound; var boundGroup; var moveBlock; var movingBlock; var bootState = { init: function () { console.log('boot') }, create: function () { //适配屏幕 game.scale.scaleMode = Phaser.ScaleManager.EXACT_FIT;
