cocos2d에서 버튼 클릭 이벤트의 라인 색상 변경

Question

저는 Cocos2D의 초보자입니다. 이제 시작하겠습니다. 나는 장면을 설정했고 Cocos2D에서 선의 색상을 변경해야합니다. 누구든지 이걸 도와 주실 수 있습니까? 어떤 도움을 주시면 감사하겠습니다.

이 작동합니다 :

-(id) init{ 

if((self = [super init])){ 

//CGSize winSize = [[CCDirector sharedDirector] winSize]; 

naughtytoucharray = [[NSMutableArray alloc] init]; 
self.isTouchEnabled = YES; 
CCMenuItem *starMenuItem = [CCMenuItemImage itemFromNormalImage:@"ButtonStar.png" selectedImage:@"ButtonStarSel.png" 
      target:self selector:@selector(starButtonTapped:)]; 

CCMenuItem *starMenuItem1 = [CCMenuItemImage itemFromNormalImage:@"ButtonPlus.png" selectedImage:@"ButtonPlusSel.png" 
      target:self selector:@selector(starButtonTapped1:)]; 

CCMenuItem *menuItem1 = [CCMenuItemImage itemFromNormalImage:@"Button1.png" selectedImage:@"Button1Sel.png" target:self selector:@selector(button1Tapped:)]; 
CCMenuItem *menuItem2 = [CCMenuItemImage itemFromNormalImage:@"Button2.png" selectedImage:@"Button2Sel.png" target:self selector:@selector(button2Tapped:)]; 
CCMenuItem *menuItem3 = [CCMenuItemImage itemFromNormalImage:@"Button3.png" selectedImage:@"Button3Sel.png" target:self selector:@selector(button3Tapped:)]; 

_scoreLabel = [CCLabelTTF labelWithString:@" MyScore" dimensions:CGSizeMake(150, 30) alignment:UITextAlignmentLeft fontName:@"Arial" fontSize:15]; 
_scoreLabel.color = ccc3(255, 0, 0); 
[_scoreLabel setPosition:ccp(80, 300)]; 

CCMenu *starMenu = [CCMenu menuWithItems:starMenuItem, nil]; 
CCMenu *starMenu1 = [CCMenu menuWithItems:starMenuItem1, nil]; 
CCRadioMenu *radioMenu = [CCRadioMenu menuWithItems:menuItem1, menuItem2, menuItem3, nil]; 



starMenuItem.position = ccp(60, 60); 
starMenuItem1.position = ccp(60, 120); 
radioMenu.position = ccp(120, 120); 

[radioMenu alignItemsVertically]; 
radioMenu.selectedItem_ = menuItem1; 
[menuItem1 selected]; 

starMenu.position = CGPointZero; 
starMenu1.position = CGPointZero; 
[self addChild:starMenu]; 
[self addChild:starMenu1]; 
[self addChild:radioMenu]; 
[self addChild:_scoreLabel]; 


} 
[_scoreLabel setString:[NSString stringWithFormat:@"MyScore: %d", score]]; 

return self; 

} 

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

UITouch *touch = [touches anyObject]; 
CGPoint new_location = [touch locationInView:[touch view]]; 
new_location = [[CCDirector sharedDirector] convertToGL:new_location]; 


CGPoint oldTouchLocation = [touch previousLocationInView:touch.view]; 
oldTouchLocation = [[CCDirector sharedDirector] convertToGL:oldTouchLocation]; 
oldTouchLocation = [self convertToNodeSpace:oldTouchLocation]; 

[naughtytoucharray addObject:NSStringFromCGPoint(new_location)]; 
[naughtytoucharray addObject:NSStringFromCGPoint(oldTouchLocation)]; 



} 

-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex 
{ 
if (buttonIndex == 0) 
{ 
exit(0); 
NSLog(@"exit"); 
} 

else if(buttonIndex == 1) 
{ 
//CCScene *scene = [CCScene node]; 
[[CCDirector sharedDirector] replaceScene:[GameScene scene1]]; 
NSLog(@"Play again"); 
} 
} 

-(void)draw 
{ 
glEnable(GL_LINE_SMOOTH); 

for (int i = 0; i < [naughtytoucharray count]; i+=2) 
{ 
CGPoint start = CGPointFromString([naughtytoucharray objectAtIndex:i]); 
CGPoint end = CGPointFromString([naughtytoucharray objectAtIndex:i+1]); 

ccDrawLine(start, end); 
glColor4ub(200, 120, 120, 255);
