nape移除碰撞中的身体

Question

我有一个函数可以检测物体何时发生碰撞，但我如何删除其中一个呢？

private function fruitToFloorCollision(collision:InteractionCallback):void
        {
            // TODO Auto Generated method stub

            trace('fruit hits floor');

        }

当我追踪碰撞的时候

Cb:BEGIN:(dynamic)#11/(static)#1 : [CollisionArbiter(Polygon#2|Circle#12)[SD]<-ACCEPT] : listener: InteractionListener{BEGIN#COLLISION::@{[CbType#5] excluding []}:@{[CbType#6] excluding []}} precedence=0

Answer 1

Nape从模拟中移除身体的首选习惯用法似乎是：

ball.space = null;

尽管它像您一样在内部调用space.bodies.remove()，但它也会执行一些额外的检查。

Answer 2

my answer.....

如果有人有更好的选择想听的话...

private function fruitToFloorCollision(collision:InteractionCallback):void
        {


            var ball:Body = collision.int1 as Body;
            removeChild(ball.userData.graphic);
            space.bodies.remove(ball);
        }

Answer 3

据我所知，考虑到你有两个对象水果和地板，interactionListener按这个顺序添加。

private function fruitToFloorCollision(collision:InteractionCallback):void
    {

        // CBTypes are added to Shapes not Bodies. So collision.int1 is a shape.

        var fruit:Body = collision.int1.castShape.body as Body;
        removeChild(fruit.userData.graphic);
        space.bodies.remove(fruit);
    }
