在 Sprite-Kit 游戏中,我想在按下按钮时为其设置动画。现在代码直接使用react,而不是等到动画执行。此外,当用户将手指从按钮上擦出时,我希望按钮能够动画回来。
Here my code:
-(void)addStartButton:(CGSize)size {
self.start = [SKSpriteNode spriteNodeWithImageNamed:@"startButton1"];
self.start.position = CGPointMake(size.width/2, size.height/2);
self.start.name = @"start";
[self addChild:self.start];
}
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch = [touches anyObject];
CGPoint location = [touch locationInNode:self];
SKNode *node = [self nodeAtPoint:location];
if ([node.name isEqualToString:@"start"]) {
self.start.texture = [SKTexture textureWithImageNamed:@"startButton2"];
MyScene *myScene = [MyScene sceneWithSize:self.size];
[self.view presentScene:myScene transition:[SKTransition pushWithDirection:SKTransitionDirectionLeft duration:0.5]];
}
}
最佳答案
在切换到另一个场景之前,这会给你 2 秒的延迟:
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch = [touches anyObject];
CGPoint location = [touch locationInNode:self];
SKNode *node = [self nodeAtPoint:location];
if ([node.name isEqualToString:@"start"]) {
SKAction *changeTexture = [SKAction runBlock:^{
self.start.texture = [SKTexture textureWithImageNamed:@"startButton2"];
}];
SKAction *wait = [SKAction waitForDuration:2.f];
SKAction *presentAnotherScene = [SKAction runBlock:^{
MyScene *myScene = [MyScene sceneWithSize:self.size];
[self.view presentScene:myScene transition:[SKTransition pushWithDirection:SKTransitionDirectionLeft duration:0.5]];
}];
[self runAction:[SKAction sequence:@[changeTexture,wait,presentAnotherScene]]];
}
}
Furthermore I want the button to animate back when the user wipes his finger out of the button.
这似乎毫无意义,因为当用户按下按钮时您正在转换到另一个场景。
