Question

Cocos2d新手在这里。我正在构建一个游戏，其中我有一个精灵和5个按钮展开。我希望精灵移动到我点击的按钮的方向。我有以下代码：

在我的初学者：

goHere1=[CCMenuItemImage itemWithNormalImage:@"goToBut.png"selectedImage:@"goToBut.png" target:self selector:@selector(imHere:)];
goHere1.position=ccp(70, 650);

然后方法：

- (void) imHere:(id)sender {
    NSLog(@"I'm Here");
    [mole runAction:[CCMoveTo actionWithDuration:1.5 position:????????)]];
}

Answer 1

您作为CCMenuItemImage的选择器操作传递的方法可以使用CCMenuItemImage方法参数访问哪个sender被触发。因此，您可以使用((CCMenuItemImage*)sender).position获取排名（需要先将sender变量转换为CCMenuItemImage）

- (void) imHere:(id)sender {
    NSLog(@"I'm Here");
    [mole runAction:[CCMoveTo actionWithDuration:1.5 position:((CCMenuItemImage*)sender).position]];
}

Answer 2

试试此代码

-(void)ccTouchEnded:(UITouch *)touch withEvent:(UIEvent *)event
{
CGPoint touchLocation=[touch locationInView:[touch view]];
touchLocation=[[CCDirector sharedDirector] convertToGL:touchLocation];
touchLocation=[self convertToNodeSpace:touchLocation];

 self.moveaction=[CCSequence actions:[CCMoveTo actionWithDuration:0.5f position:touchLocation],[CCCallFunc actionWithTarget:self selector:@selector(moveend)],nil];
[sprite runAction:moveaction];
 }

我希望这会对你有所帮助。

据我所知，你不应该使用moveTo方法来动画精灵。你没注意到当你使用'moveto'时你的动作不顺畅吗？

我是这样做的，也许并不完美。

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

    UITouch *myTouch = [touches anyObject];
    CGPoint location = [zoombase convertTouchToNodeSpace:myTouch];
    self.destinationLocation = loaction;
}
-(void)ccTouchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
     UITouch *myTouch = [touches anyObject];
    CGPoint location = [zoombase convertTouchToNodeSpace:myTouch];
    self.destinationLocation = loaction;
}

-(void)update:(ccTime)dt {

    //that will do until your sprite reach you destination point
    if(!CGPointEqualToPoint(self.spriteToMove,self.destinationLocation)) {
        CGPoint *stepToMove = ccp(0.2/destinationLocation,0.2/destinationLocation); //some piece of orginal destination
        [self.spriteToMove setPosition:ccpAdd(stepToMove,self.spriteToMove.position)]; // add that pice to your sprite current location
    }
}

Cocos2d精灵MoveTo点击按钮？
