为什么碰撞不起作用，cocos2d v3? [英] why collision not working , cocos2d v3?

问题描述

我用 cocos2d v3 创建了简单的游戏，比如小鸟.接口类:

i create simple game like flapy bird with cocos2d v3 . Interface class:

@interface GameScene : CCScene<CCPhysicsCollisionDelegate>

// -----------------------------------------------------------------------

+ (GameScene *)scene;
- (id)init;

// -----------------------------------------------------------------------
@end

在 .m 文件中:

          _physicsWorld =[CCPhysicsNode node];
          _physicsWorld.gravity=ccp(0, 0);
          _physicsWorld.collisionDelegate=self;
          _physicsWorld.debugDraw =YES;
          [self addChild:_physicsWorld];
          .........
          bird.physicsBody=[CCPhysicsBody bodyWithRect:(CGRect){CGPointZero,bird.contentSize} cornerRadius:0];
          bird.physicsBody.collisionGroup=@"birdGroup";
          bird.physicsBody.collisionType=@"birdCollision";
           [_physicsWorld addChild:bird];
          ........

    tubeBody.physicsBody.collisionGroup =@"tubeGroup";
    tubeBody.physicsBody.collisionType=@"tubeCollision";
    tubeBody.physicsBody.type=CCPhysicsBodyTypeStatic;

    [_physicsWorld addChild:tubeBody];
-(BOOL)ccPhysicsCollisionBegin:(CCPhysicsCollisionPair *)pair typeA:(CCNode *)nodeA typeB:(CCNode *)nodeB{
    [self endGame];
    NSLog(@"end game");
    return YES;
}

为什么方法 ccPhysicsCollisionBegin 从不调用?

why method ccPhysicsCollisionBegin never call?

推荐答案

改变

-(BOOL)ccPhysicsCollisionBegin:(CCPhysicsCollisionPair *)pair typeA:(CCNode *)nodeA typeB:(CCNode *)nodeB{

收件人:

-(BOOL)ccPhysicsCollisionBegin:(CCPhysicsCollisionPair *)pair tubeCollision:(CCNode *)nodeA birdCollision:(CCNode *)nodeB{

您有碰撞委托的示例代码，因此您必须将其调整为您的代码，其中 nodeA 是管子，nodeB 是鸟.

You have the example code of the collision delegate, so you have to adapt it to your code with your nodeA that is the tube and nodeB the bird.
