[英]How can i make the 'poo' appear in a certain place when the screen is touched?
我正在用精灵套装制作游戏,对于iphone而言我是一个菜鸟哈哈。 无论如何,这是我到目前为止的代码,但不是在我触摸的地方出现的便便,我希望它出现在我选择的地方。
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
/* Called when a touch begins */
for (UITouch *touch in touches) {
CGPoint location = [touch locationInNode:self];
SKSpriteNode *poo = [SKSpriteNode spriteNodeWithImageNamed:@"poo"];
poo.position = location;
poo.zPosition = 5;
[poo setScale:0.2f];
//next line adds gravity to the poo.
poo.physicsBody = [SKPhysicsBody bodyWithCircleOfRadius:poo.size.width/2];
[self addChild:poo];
}
}
只需创建一个具有所需位置的CGPoint
并将其设置为一个位置:
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
CGPoint yourLocationOfChoice = CGPointMake(200.0f, 200.0f);
SKSpriteNode *poo = [SKSpriteNode spriteNodeWithImageNamed:@"poo"];
poo.position = yourLocationOfChoice;
...
}
