var Wall_TL = new Sprite();
Laya.stage.addChild(Wall_TL);
Wall_TL.graphics.drawRect(0, 0, 400, 32, "#ffff00");
Wall_TL.pivot(200, 16);
var Collision_Wall_TL:any = Matter.Bodies.rectangle(200, 400, 400, 32, { layaSprite:Wall_TL,isStatic: true })
Matter.World.add(this.engine.world,
[
Collision_Wall_TL,
// Collision_Wall_R,
// Collision_Wall_TL
]);
如何旋转这个对象 让它倾斜45度啊
