ios - SpriteKit 动画错误

Question

我想把英雄跳起来做成动画

 NSArray *animatedImages = [NSArray arrayWithObjects:
                                   [UIImage imageNamed:@"hero_1.png"],
                                   [UIImage imageNamed:@"hero_2.png"],
                                   [UIImage imageNamed:@"hero_1.png"],
                                   [UIImage imageNamed:@"hero_.png"], nil];
    SKAction *jump = [SKAction animateWithTextures:animatedImages timePerFrame:0.2];
    [hero runAction:jump];

这段代码放在didBeginContact

您不能为 UIImage 对象设置动画，它们必须是 SKTexture 对象。

NSArray *animatedImages = [NSArray arrayWithObjects:
                               [SKTexture textureWithImageNamed:@"hero_1.png"],
                               [SKTexture textureWithImageNamed:@"hero_2.png"],
                               [SKTexture textureWithImageNamed:@"hero_1.png"],
                               [SKTexture textureWithImageNamed:@"hero_.png"], nil];
