在cocos creator中使用代码给TileMap地图块添加碰撞体

cc.Class({
    extends: cc.Component,

    properties: {
        tiledMap:cc.TiledMap
    },

    // LIFE-CYCLE CALLBACKS:

    onLoad () {
　　　　　//开启物理效果
        cc.director.getPhysicsManager().enabled = true;
        cc.director.getPhysicsManager().debugDrawFlags = true;
    },

    start () {
        let tiledSize = this.tiledMap.getTileSize();
        let layer = this.tiledMap.getLayer("这里填需要添加碰撞体的组名");
        let layerSize = layer.getLayerSize();

        for(let i = 0;i < layerSize.width;i++){
            for (let j = 0; j < layerSize.height; j++) {
                let tiled = layer.getTiledTileAt(i,j,true);
                if (tiled.gid != 0) {
                    tiled.node.group = "这里填需要添加碰撞体的组名";
                    let body = tiled.node.addComponent(cc.RigidBody);
                    body.type = cc.RigidBodyType.Static;
                    let collider = tiled.node.addComponent(cc.PhysicsBoxCollider);
                    collider.offset = cc.v2(tiledSize.width/2,tiledSize.height/2);
                    collider.size = tiledSize;
                    collider.apply();
                }
                
            }
        }
    },

    // update (dt) {},
});
