How to disable touch on a CGRect / Sprite after one touch - ios

Question

How can I disable touches for a CCRect / sprite after it has been touched?
I have in my init method to set the sprite:
[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:#"testAtlas_default.plist"];
sceneSpriteBatchNode = [CCSpriteBatchNode batchNodeWithFile:#"testAtlas_default.png"];
[self addChild:sceneSpriteBatchNode z:0];
dinosaur1_c = [CCSprite spriteWithSpriteFrameName:#"dinosaur1-c.png"];
[sceneSpriteBatchNode addChild:dinosaur1_c];
[dinosaur1_c setPosition:CGPointMake(245.0, winSize.height - 174.0)];
I then create a CGRect using the position and size of the sprite as its parameters in:
-(BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event
{
CGPoint touchLocation = [touch locationInView:[touch view]];
touchLocation = [[CCDirector sharedDirector] convertToGL:touchLocation];
touchLocation = [self convertToNodeSpace:touchLocation];
dinosaur1 = CGRectMake(dinosaur1_c.position.x - (dinosaur1_c.contentSize.width / 2), dinosaur1_c.position.y - (dinosaur1_c.contentSize.height / 2), dinosaur1_c.contentSize.width, dinosaur1_c.contentSize.height);
if( CGRectContainsPoint(dinosaur1, touchLocation) )
{
CCLOG(#"Tapped Dinosaur1_c!");
PLAYSOUNDEFFECT(PUZZLE_SKULL);
// Code to disable touches??
// Tried to resize CGRect in here to (0, 0, 1, 1) to get it away from the original sprite, but did not work. Still was able to tap on CGRect.
// Tried [[CCTouchDispatcher sharedDispatcher] setDispatchEvents:NO];, but disables ALL the sprites instead of just this one.
}
}
I'm able to successfully tap on the sprite to make it play the sound, however I just can't figure out how to disable the CGRect after it is touched. I have tried different methods as commented in the code above. Any ideas or tips are appreciated!

Answer 1

this will also help you
- (void)selectSpriteForTouch:(CGPoint)touchLocation {
for (CCSprite *sprite in _projectiles) {
if (CGRectContainsPoint(sprite.boundingBox, touchLocation)) {
NSLog(#"sprite was touched");
[sprite.parent removeChild:sprite cleanup:YES];
[self removeChild:sprite.parent cleanup:YES];
}
} }
- (BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event {
CGPoint touchLocation = [self convertTouchToNodeSpace:touch];
[self selectSpriteForTouch:touchLocation];
NSLog(#"touch was _");
return TRUE; }

Ok so I solved the problem. In case anyone was wondering, I set up a -(BOOL)isTapped in my header file and set it to NO in my init method.
When I check for collisions with the touchpoint and the CGRect, I also check to see if isTapped != YES (meaning it hasnt been tapped yet). In that if statement, I do all the actions as normally would but then set isTapped = YES. Now it will skip over when I tap again. Below is my code with the added bits in between *'s
.h file:
BOOL isTapped;
and in the .m file:
.m:
-(id)init
{
isTapped = NO;
// Rest of init method.
}
-(BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event
{
CGPoint touchLocation = [touch locationInView:[touch view]];
touchLocation = [[CCDirector sharedDirector] convertToGL:touchLocation];
touchLocation = [self convertToNodeSpace:touchLocation];
dinosaur1 = CGRectMake(dinosaur1_c.position.x - (dinosaur1_c.contentSize.width / 2), dinosaur1_c.position.y - (dinosaur1_c.contentSize.height / 2), dinosaur1_c.contentSize.width, dinosaur1_c.contentSize.height);
if( CGRectContainsPoint(dinosaur1, touchLocation) **&& isTapped != YES**)
{
CCLOG(#"Tapped Dinosaur1_c!");
PLAYSOUNDEFFECT(PUZZLE_SKULL);
**isTapped = YES;**
}
else
{
CCLog(#"Already Tapped!");
}
}
Thanks for looking!
