アドバイスが必要です。私のGameSceneには、ポイントラベルcurentPointsLabelがあります。更新するために関数がありますが、パフォーマンスupdateCurentPoints(CCSequence)の後、ポイントラベルが消えます!なぜ?
init
_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];
ポイントラベルを更新したいとき
- (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];
}
//*******************************************************************

label.color = ccc3(255,255,255);//white

label.color = ccc3(0,255,0);//green
