我遇到了我的英雄角色的问题,当他落在一个移动的平台上,而不是随着它一起移动时,他确实站在同一个X位置,直到平台离开屏幕.我搜索了许多答案但没有用.

这是我的英雄角色和移动平台的方法.

-(void)HeroAdd
{    
    _Hero = [SKSpriteNode spriteNodeWithImageNamed:@"Hero-1"];
    _Hero.name = @"Daniel";
    _Hero.physicsBody = [SKPhysicsBody bodyWithRectangleOfSize:_Hero.size];
    _Hero.physicsBody.categoryBitMask = fPlayerCategory;
    _Hero.physicsBody.contactTestBitMask = fPlatformCategory | fEnemyCategory;
    _Hero.physicsBody.usesPreciseCollisionDetection = YES;
    _Hero.physicsBody.affectedByGravity = YES;
    _Hero.physicsBody.dynamic = YES;
    _Hero.physicsBody.friction = .9;
    _Hero.physicsBody.restitution = 0;
    _Hero.position = CGPointMake(CGRectGetMidX(self.frame), CGRectGetMidY(self.frame));
    _Hero.position = CGPointMake(_Hero.position.x - 252, _Hero.position.y + 50);

    if (self.size.width == 480) {
        _Hero.position = CGPointMake(_Hero.position.x + 44, _Hero.position.y);
    }

    [self addChild:_Hero];
}

我的移动平台代码

-(void)createPlatform {

    SKTexture *objectTexture;

    switch (arc4random_uniform(2)) {
        case (0):
            objectTexture = [SKTexture textureWithImageNamed:@"shortPlatform"];
            break; …
