Create.js键盘事件处理机制

直接上代码，怕自己忘记

$(window).unbind(“keydown”);
$(window).bind(“keydown”, (ev)=>{
let keyMap = {
“37”: “left”,
“38”: “up”,
“39”: “right”,
“40”: “down”
};
if (keyMap[ev.keyCode]) {
ev.preventDefault();
if(keyMap[ev.keyCode] === “left” && 30<sheetContainer.x){
// console.log(123);
// sheetContainer.scaleX = sheetContainer.scaleX;
createjs.Tween.get(sheetContainer).to({ x: sheetContainer.x-this.playLeft }, 1000)
}else if(keyMap[ev.keyCode] === “right”&& sheetContainer.x<1000){
// console.log(123);
// sheetContainer.scaleX = -sheetContainer.scaleX;
createjs.Tween.get(sheetContainer).to({ x: sheetContainer.x+this.playLeft }, 1000)
}else{
console.log(“按的是上下键”);
}
}
})
