我需要帮助

我正在开发一个简单的 2d 游戏，其中角色左右行走。

我正在使用我应用 CCAnimation 的 6 帧的sneakyjoystick 和步行动画

我遇到的问题是，当我从操纵杆更新方法调用动画时，动画仅在我从左操纵杆释放左或右按钮时开始......在我看来，我错过了一些简单的东西，但我无法弄清楚...

-(void) update:(ccTime)deltaTime
{
    CGPoint scaleVelocity = ccpMult(leftJoystick.velocity, 100);
    CGPoint oldPosition = [self.Bartender position];
    CGPoint newPosition = ccp(self.Bartender.position.x + scaleVelocity.x * deltaTime, self.Bartender.position.y + scaleVelocity.y * deltaTime);


    [self.Bartender setPosition:newPosition];
    if (oldPosition.x > newPosition.x) {

        [self.Bartender stopAllActions];
        self.Bartender.flipX = YES;
        [self GoWalk];

    } else if (oldPosition.x == newPosition.x) {

        // Intentionally do nothing to preserve orientation at start of scene!
        NSLog(@"equal");

    } else {

        [self.Bartender stopAllActions];
        self.Bartender.flipX = NO;
        [self GoWalk];
    }


    /*
     if(oldPosition.x > newPosition.x)
     {
     aChar.flipX = YES;
     }
     else if(aChar.flipX == YES)
     {
     aChar.flipX = NO;
     }

     if(jumpButton.active == YES)
     {
     CCLOG(@"jump pressed");
     }
     if(attackButton.active == YES)
     {
     CCLOG(@"attack pressed");
     }

     [aChar setPosition:newPosition];*/

}


-(void)GoStand
{
    self.StandAnimation = [CCAnimation animation];

    [self.StandAnimation addFrame:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:@"AStand1.png"]];
    [self.StandAnimation addFrame:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:@"AStand1.png"]];
    [self.StandAnimation addFrame:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:@"Walk4.png"]];
    [self.StandAnimation addFrame:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:@"AStand1.png"]];
    [self.StandAnimation addFrame:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:@"AStand1.png"]];

    id animatedAction = [CCAnimate actionWithDuration:0.8f animation:self.StandAnimation restoreOriginalFrame:NO];
    id repeatAction = [CCRepeatForever actionWithAction:animatedAction];
    [self.Bartender runAction:repeatAction];
}

-(void)GoWalk
{
    self.WalkAnimation = [CCAnimation animation];

    [self.WalkAnimation addFrame:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:@"Walk1.png"]];
    [self.WalkAnimation addFrame:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:@"Walk2.png"]];
    [self.WalkAnimation addFrame:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:@"Walk3.png"]];
    [self.WalkAnimation addFrame:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:@"Walk4.png"]];
    [self.WalkAnimation addFrame:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:@"Walk5.png"]];
    [self.WalkAnimation addFrame:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:@"Walk6.png"]];

    id animatedAction = [CCAnimate actionWithDuration:0.8f animation:self.WalkAnimation restoreOriginalFrame:NO];
    id repeatAction = [CCRepeatForever actionWithAction:animatedAction];
    [self.Bartender runAction:repeatAction];
}

有人吗？

你的问题是你太频繁地开始你的动画。如果您的 fps 为 60，则每秒大约 60 次。因此，您尝试在每个滴答声中都在节点上运行操作。
