Cocos v3.4中创建二维接触物理时的未明误差破坏()
Cocos v3.4中创建二维接触物理时的未明误差破坏()
提问于 2022-02-01 16:26:35
我使用可可仪表板1.02和可可创建者v3.4。添加以下代码时出错: this.node.destroy()；以删除预置文件。
(我试图在coscos：https://docs.cocos.com/creator/manual/en/physics-2d/physics-2d-contact-callback.html?h=contact中使用DOC )
请帮帮我。
我的代码：
@ccclass('Ball')
export class Ball extends Component {
start () {
// Registering callback functions for a single collider
let collider = this.getComponent(Collider2D);
if (collider) {
collider.on(Contact2DType.BEGIN_CONTACT, this.onBeginContact, this);
}
}
onBeginContact (selfCollider: Collider2D, otherCollider: Collider2D, contact: IPhysics2DContact | null) {
// will be called once when two colliders begin to contact
this.node.destroy();//// ERROR WHEN I ADD THIS LINE
console.log('onBeginContact');
}
}
还有我的游戏经理
@ccclass('GameManager')
export class GameManager extends Component {
@property({type: Prefab})
public ballPrfb: Prefab|null = null;
@property({type: Node})
public Player: Node|null = null;
@property({type: CCInteger})
public _spawnTime: number = 2;
private TimeFalling : number;
start () {
this.TimeFalling = 0;
}
update (deltaTime: number) {
this.TimeFalling = this.TimeFalling - deltaTime;
let block = instantiate(this.ballPrfb);
if(this.TimeFalling <=0){
this.node.removeAllChildren();
this.node.addChild(block);
block.setPosition(Math.random() * 800, 0, 0);
this.TimeFalling = this._spawnTime;
}
}
