我是 Spritebuilder 的新手，正在尝试制作 MARIO 游戏原型。我正在做的是我有 2 个精灵，一个精灵具有快速行走的特性，另一个具有正常行走的特性。我正在通过一个按钮更改精灵。当我单击按钮时，正常行走的精灵被快速行走的精灵替换，然后再次单击该按钮使正常的精灵出现。

问题 ：

  1. 游戏开始时第一次在跳跃时检测到地面和角色之间的碰撞。但是，一旦我将精灵更改为快走角色，跳跃时就没有检测到碰撞。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。

  2. 当我让精灵跳跃并开始下落时，观察到某种活动（我更愿意说弹跳），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，您可以在此链接上查看视频以了解完整的问题。https://www.dropbox.com/s/0fz3qehie76r60k/Game.mp4?dl=0

请帮忙。欢迎任何建议。

编辑：这是我更改精灵的代码：

-(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碰撞，使用不太密集的节点进行碰撞非常有效：

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