Stop SKAction that RepeatsForever - Sprite Kit

问题:

I want to run two animations on my spriteNode depending on its rotation. If the value is negative run one of the animations, if it's positive run the other. And I managed to do that (kind of) but I have a problem. If Animation1 is running, and zRotation changes to positive, they both run because they are repeating forever. So I did this :

NSMutableArray *walkingTextures = [NSMutableArray arrayWithCapacity:14];


for (int i = 1; i < 15; i++) {
    NSString *textureName =
    [NSString stringWithFormat:@"character%d", i];
    SKTexture *texture =
    [SKTexture textureWithImageNamed:textureName];
    [walkingTextures addObject:texture];
}

SKAction *spriteAnimation = [SKAction animateWithTextures:Textures timePerFrame:0.04];
    repeatWalkAnimation = [SKAction repeatActionForever:spriteAnimation];
    [sprite runAction:repeatWalkAnimation withKey:@"animation1"];

and then when I want it to stop :

    [self removeActionForKey:@"animation1"];

but it keeps running the action, how can I stop the action, then? Thank you!

回答1:

The method is supposed to be called on the node which the SKAction is running on.

Change

[self removeActionForKey:@"animation1"]; 

to

[sprite removeActionForKey:@"animation1"];
