请问应该如何触发碰撞回调?

Creator 2.x

我做了一个球，一个方块，相应的组件都有放上，球会往右移动，碰到方块，可是没有触发碰撞回调，想请问是哪边出错了。

球脚本
const {ccclass, property} = cc._decorator;`

    @ccclass
    export default class Ball extends cc.Component {

        manager:cc.CollisionManager;

        onLoad() {
            // init logic
            this.manager = cc.director.getCollisionManager();
            this.manager.enabled = true;
            this.manager.enabledDebugDraw = true;
            this.manager.enabledDrawBoundingBox = true;

        }

        update(dt){
            this.node.x += 10;
        }

        onCollisionEnter(other, self) {
            console.log('5555555');
        }
    }


方块脚本
    const {ccclass, property} = cc._decorator;

    @ccclass
    export default class Block1 extends cc.Component {

        manager:cc.CollisionManager;

        onLoad() {
            // init logic
            this.manager = cc.director.getCollisionManager();
            this.manager.enabled = true;
            this.manager.enabledDebugDraw = true;
            this.manager.enabledDrawBoundingBox = true;

        }

        onCollisionEnter(other, self) {
            console.log('44444444');
        }
    }

场景脚本
const {ccclass, property} = cc._decorator;

@ccclass
export default class Game extends cc.Component {

    manager:cc.CollisionManager;

    onLoad() {
        // init logic
        this.manager = cc.director.getCollisionManager();
        this.manager.enabled = true;
        this.manager.enabledDebugDraw = true;
        this.manager.enabledDrawBoundingBox = true;
    }
}

原来是碰撞群组忘记打勾:8:
