我需要你的建议。在我的 GameScene 中,我有一个点标签curlentPointsLabel。要更新我有一个功能,但是在性能updateCurentPoints (CCSequence) 之后点标签消失了!为什么?
在初始化
_curentPointsLabel = [CCLabelTTF labelWithString:@"" dimensions:CGSizeMake(screenSize.width*0.17f, screenSize.height*0.1f) alignment:UITextAlignmentLeft fontName:@"Trebuchet MS" fontSize:15];
_curentPointsLabel.anchorPoint = CGPointMake(1, 1);
_curentPointsLabel.position = ccp( screenSize.width-screenSize.height/20, screenSize.height-2*screenSize.height/20);
_curentPointsLabel.color = ccc3(0,0,0);
[self addChild:_curentPointsLabel];
当我想要更新点标签时
- (void)updateCurentPoints:(int)points {
if(_curentPoints+points<0)
_curentPoints=0;
else
_curentPoints=_curentPoints+points;
// [_curentPointsLabel setString:[NSString stringWithFormat:@"Score: %d",_curentPoints]];
NSString * valueString=[[[NSString alloc] initWithString:[NSString stringWithFormat:@"Score: %d",_curentPoints]] retain];
id sequence=[CCSequence actions:
[CCCallFuncND actionWithTarget: self selector: @selector(setLabelColor:withIndex:) data:(void*)1],
[CCCallFuncND actionWithTarget: self selector: @selector(setLabelValue:withValue:) data:(NSString*)valueString],
[CCBlink actionWithDuration:0.5f blinks:2],
[CCCallFuncND actionWithTarget: self selector: @selector(setLabelColor:withIndex:) data:(void*)3],
nil];
[_curentPointsLabel runAction:sequence];
[valueString release];
}
//*******************************************************************
-(void) setLabelValue:(id) sender withValue:(NSString*) value
{
CCLabelTTF *label=(CCLabelTTF *)sender;
NSString * valueString=[[[NSString alloc] initWithString:[NSString stringWithFormat:@"%@",value]] retain];
[label setString:[NSString stringWithFormat:@"%@",valueString]];
[valueString release];
}
//*******************************************************************
-(void) setLabelColor:(id) sender withIndex:(int)index
{
CCLabelTTF *label=(CCLabelTTF *)sender;
if(index==0)
label.color = ccc3(255,255,255);//white
else if(index==1)
label.color = ccc3(0,255,0);//green
else if(index==2)
label.color = ccc3(255,0,0);//red
else if(index==3)
label.color = ccc3(0,0,0);//black
NSLog(@"color:%i",index);
}
