我是Cocos2d的新手,尝试从正常的Cocoa Touch到Cocos2d的端口游戏。
我通过自定义方法创建了一些按钮:
+ (CCMenuItem *)createMenuItemImageWithNormalImage:(NSString *)normalImage selectedImage:(NSString *)selectedImage tag:(int)tag target:(id)target selector:(SEL)selector position:(CGPoint)position {
CCMenuItem *item = [CCMenuItemImage itemWithNormalImage:normalImage selectedImage:selectedImage];
item.tag = tag;
[item setTarget:target selector:selector];
item.position = [TSCCTransform transformPositionFromCocoaTouchToCocos2d:CGPointMake(position.x, position.y)];
return item;
}
按钮:
[self addChild:[TSCCLayer createMenuItemImageWithNormalImage:@"btn-mouse-dec.png" selectedImage:@"btn-mouse-dec.png" tag:0 target:self selector:@selector(changeNumberOfPlayers:) position:ccp([TSCCTransform winSizeWidth] - 140, 146)]];
但是当我点击它时没有任何反应。哪里有问题?怎么做得对?
答案 0 :(得分:1)
您不必向其添加菜单项,而是添加菜单。
将CCMenuItem添加到CCMenu,然后将菜单添加为图层的子级:
CCMenuItem* item=[TSCCLayer createMenuItemImageWithNormalImage:@"btn-mouse-dec.png" selectedImage:@"btn-mouse-dec.png" tag:0 target:self selector:@selector(changeNumberOfPlayers:) position:ccp([TSCCTransform winSizeWidth] - 140, 146)]
CCMenu* menu= [CCMenu menuWithItems: item, nil]; // item becomes child of menu
[self addChild: menu];
