Body
copied!<p>I've been stumped for days trying to get my sprite touch method under control. My aim is to have another sprite pop up offset to a touched sprite.</p> <p>I currently have a half baked code for this process, in which I have experimented with many varieties of code, see links below, none of which has worked. My questions:</p> <ol> <li>Getting CCTouchBegan to run the method towerPositionTapped once the touch hits a sprite on screen (the NSLog in CCTouchBegan is also not working).</li> <li>Find out how to get the location of the touched sprite so that it can be used in the towerPositionTapped method.</li> </ol> <p><strong>My touch specific code so far in the main layer:</strong></p> <pre><code>-(void) registerWithTouchDispatcher{ [[[CCDirector sharedDirector] touchDispatcher] addTargetedDelegate:self priority:0 swallowsTouches:YES]; } -(BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event{ CGPoint location = [touch locationInView: [touch view]]; location = [[CCDirector sharedDirector] convertToGL: location]; //_towersFromClass is an NSMutableArray with CCSprite objects for(CCSprite *tb in _towersFromClass){ if(CGRectContainsPoint(tb.boundingBox,location)){ NSLog(@"sprite touched at %@", NSStringFromCGPoint(location)); [self towerPositionTapped] return YES; } } return NO; } </code></pre> <p>The NSLog check doesn't end up showing when I click on any of the sprites. </p> <p>For the towerPositionTapped method I am unsure how to capture the touched location (or record the touched sprite) in order to position the new sprite.</p> <p><strong>towerPositionTapped.m</strong></p> <pre><code>-(void)towerPositionTapped{ CCMenuItem *towerOption1 = [CCMenuItemImage itemWithNormalImage:@"tower.png" selectedImage:@"tower.png"]; towerOption1.position = /* place touched sprite location here, with an offset*/; CCMenu *_towerOptionsMenu = [CCMenu menuWithItems: nil]; _towerOptionsMenu.position = CGPointZero; [self addChild:_towerOptionsMenu z:5]; </code></pre> <p>}</p> <p>Any constructive criticism is appreciated.
