ios - SKA行动向前推进

Question

如何让 SKNode 继续前进？

我已经能够使用 [SKAction moveByX:y:duration:] 让节点沿固定方向移动，但我希望它沿相对于其面向方向的方向移动.

我希望让每个节点旋转 45 度，然后向前“行走”50 像素。

看起来很简单，我只是找不到它。

它将旋转，然后朝着您点击的位置旋转

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {

for (UITouch *touch in touches) {

    for (UITouch *touch in touches) {

        CGPoint location = [touch locationInNode:self];

        CGPoint diff = CGPointMake(location.x - _myPlayer.position.x, location.y - _myPlayer.position.y);

        CGFloat angleRadians = atan2f(diff.y, diff.x);

        [_myPlayer runAction:[SKAction sequence:@[
                                [SKAction rotateToAngle:angleRadians duration:1.0],
                                [SKAction moveByX:diff.x y:diff.y duration:3.0]
                                ]]];
    }
}
}
