cocos2d v3碰撞检测 [英] cocos2d v3 collision detection

问题描述

我试图检查两个物体的碰撞碰撞，但碰撞检测回调没有被触发。
这是我的代码：

I'm trying to inspect collision collision of two bodies, but collision detection callbacks are not being fired. Here is my code:

1）我的CCScene实现CCPhysicsCollisionDelegate协议

1) My CCScene implements CCPhysicsCollisionDelegate protocol

碰撞委托物理

_physics = [CCPhysicsNode node];
_physics.gravity = PHYSICS_GRAVITY;
_physics.debugDraw = YES;
_physics.collisionDelegate = self;
[self addChild:_physics];

3）对于两个主体中的每一个，我设置了一个碰撞类型

3) For each of two body I set a collision type

body1.collisionType       = @"body1";
body2.collisionType       = @"body2";

4）就是这样，当这两个机构碰撞时，CCPhysicsCollisionDelegate没有调用回调方法。 p>

4) That's it, when these two bodies collide none of CCPhysicsCollisionDelegate callback methods is being called.

- (BOOL)ccPhysicsCollisionBegin:(CCPhysicsCollisionPair *)pair typeA:(CCNode *)nodeA     typeB:(CCNode *)nodeB
{
    NSLog(@"HELLO");
    return YES;
}

你能帮我一下吗？

提前感谢

推荐答案

在cocos2d v3物理中， collisionType 不需要设置整数位掩码来定义冲突类型。参数名 CCPhysicsCollisionDelegate 方法必须是您想要处理的collisionTypes。所以在你的情况下，碰撞回调方法应该是

In cocos2d v3 physics, collisionType eliminates the need to set integer bit masks to define the type of collision. The parameter name CCPhysicsCollisionDelegate methods must be the collisionTypes that you want to deal with yourself. So in your case , the collision callback method should be

- (BOOL)ccPhysicsCollisionBegin:(CCPhysicsCollisionPair *)pair body1:(CCNode *)nodeA     body2:(CCNode *)nodeB
{
    NSLog(@"HELLO");
    return YES;
}

默认情况下，一切都会在cocos2d中碰撞，但如果您设置 collisionGroup 两个主体相同，则它们不会发生冲突。

By default everything collides in cocos2d, but if you set the collisionGroup of two bodies to be the same then they wouldn't collide.
