Question

我是Spritebuilder的新手并试图制作MARIO游戏原型。我正在做的是我有2个精灵，一个精灵有快速行走的角色，而另一个有正常的行走角色。我正在通过一个按钮更改精灵。当我点击按钮时，正常行走的精灵被快速行走的精灵所取代，再次单击该按钮会使正常的精灵出现。

问题：

在游戏开始的第一次，在跳跃时在地面和角色之间检测到碰撞。但是只要我将精灵更改为快速行走角色，就不会在跳跃时检测到碰撞。当我再次切换回正常行走角色时，跳跃时也没有检测到碰撞。
当我让精灵跳跃并开始摔倒时，观察某种活动（我宁愿说弹跳），我也不能说它是否弹回。我不知道它为什么会来，以及如何纠正它。我搜索了堆栈溢出和一些论坛。我发现的是使用

CCPhysicsBody.iterations

但我不知道如何使用它。有关更详细的说明，您可以在此链接中查看视频，以了解完整问题。 https://www.dropbox.com/s/0fz3qehie76r60k/Game.mp4?dl=0

请帮忙。欢迎任何建议。

编辑：这是我改变精灵的代码：

-(void)setCharacterAnimationFast
{
    if (_turboButton.selected)
    {
        //changing button state;
        _turboButton.selected=NO;

        //changing value of background speed from screen;
        speeedParameter = 50.0;
        speedParameterOfBackgroundObjects=10.0;

        //loading new chracter
        _character =(RightCharacter*)[CCBReader load:@"RightCharacter"];

        //position the laser at helicopter origin
        CGPoint _characterPosition = _fastCharacter.position;

        //transform the world position to the node space to which the laser will be added (_physicsNode)
        _character.position = [_physicsNode convertToNodeSpace:_characterPosition];

        //defining zorder for moving it to background
        _character.zOrder= _fastCharacter.zOrder;

        // add the laser to the physicsNode of this scene (because it has physics enabled)
        [_physicsNode addChild:_character];

        //removing the existing character
        [_fastCharacter removeFromParentAndCleanup:YES];



        CCLOG(@"ground : %@", _ground);
        CCLOG(@"ground : %@", _ground.physicsBody);
        CCLOG(@"ground : %@", _ground.physicsNode);



        _ground.physicsBody.collisionMask=@[@"character"];
        _character.physicsBody.collisionMask=@[@"ground"];
        _ground.physicsBody.collisionType=@"ground";
        _ground.physicsBody.elasticity=0;
        _character.physicsBody.collisionType=@"character";
        _character.physicsBody.elasticity=0;
        _physicsNode.iterations=1000;

        _fastCharacter=nil;
    }
    else
    {
        //changing button state
        _turboButton.selected=YES;

        //changing value of background speed from screen;
        speeedParameter = 80.0;
        speedParameterOfBackgroundObjects= 20.0;

        //loading new fast character
        _fastCharacter =(RightCharacterFast*)[CCBReader load:@"RightCharacterFast"];

        //position the laser at helicopter origin
        CGPoint _fastCharacterPosition = _character.position;

        //transform the world position to the node space to which the laser will be added (_physicsNode)
        _fastCharacter.position = [_physicsNode convertToNodeSpace:_fastCharacterPosition];

        //defining zorder for moving it to background
        _fastCharacter.zOrder= _character.zOrder;

        // add the laser to the physicsNode of this scene (because it has physics enabled)
        [_physicsNode addChild:_fastCharacter];

        //removing the existing character
        [_character removeFromParentAndCleanup:YES];



        CCLOG(@"ground : %@", _ground);
        CCLOG(@"ground : %@", _ground.physicsBody);
        CCLOG(@"ground : %@", _ground.physicsNode);


        _ground.physicsBody.collisionMask=@[@"fastCharacter"];
        _fastCharacter.physicsBody.collisionMask=@[@"ground"];
        _ground.physicsBody.elasticity=0;
        _ground.physicsBody.collisionType=@"ground";
        _fastCharacter.physicsBody.collisionType=@"fastCharacter";
        _fastCharacter.physicsBody.elasticity=0;
        _physicsNode.iterations=1000;

        _character=nil;
    }
}

使用相同的代理主体节点进行冲突，使用较少密集的节点进行冲突非常有效：

characterNode.physicsBody = [SKPhysicsBody bodyWithCircleOfRadius:sprite.size.width/2];
fastWalkingCharacterNode.physicsBody = [SKPhysicsBody bodyWithCircleOfRadius:sprite.size.width/2];

CCSprite没有响应Collision
