In my game, when player contact with a flag (using DidBeginContact) I add an SKSpritenode "nextlevel" (which is not responding in TouchesBegan and I don't know why. The NSLog code in TouchesBegan is not working.
This my code:
-(void)nextlevel
{
nextlevel = [SKSpriteNode spriteNodeWithImageNamed:#"nextlevel.png"];
nextlevel.userInteractionEnabled = NO;
nextlevel.name = #"nextlevel";
nextlevel.position = CGPointMake(self.size.width / 2.0, self.size.height / 2.0);
[self addChild:nextlevel];
}
- (void)didBeginContact:(SKPhysicsContact *)contact
{
SKPhysicsBody *firstBody, *secondBody;
if (contact.bodyA.categoryBitMask < contact.bodyB.categoryBitMask)
{
firstBody = contact.bodyA;
secondBody = contact.bodyB;
}
else
{
firstBody = contact.bodyB;
secondBody = contact.bodyA;
}
if((firstBody.categoryBitMask == playerCategory && secondBody.categoryBitMask == flagCategory) ||
(firstBody.categoryBitMask == flagCategory && secondBody.categoryBitMask == playerCategory))
{
// PLAYER WINS
NSLog(#"player touches flag");
SKAction * wait = [SKAction waitForDuration:1.2];
SKAction *performSelector = [SKAction performSelector:#selector(nextlevel) onTarget:self];
[self runAction:[SKAction sequence:#[wait, performSelector]]];
}
}
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch = [touches anyObject];
CGPoint location = [touch locationInNode:self];
SKNode *node = [self nodeAtPoint:location];
// Nextlevel splash screen
if ([node.name isEqualToString:#"nextlevel"]) {
NSLog(#“Next Level was touched!");
}
}
It's possible your SKSpriteNode is obstructed by another Node on top of it.
Try setting the zPosition above all other nodes. Try different values depending on the zPositions of the other nodes in your scene.
nextlevel.zPosition = 10.0f;
in one part of my project I need to create some UI objects programmatically, can I just customize my UI Objects like labels,... visually in storyboard then simply copy/paste generated code relevant to that object?
I searched in xcode menu but I couldn't find this but once I saw it in a tutorial in youtube.
Thanks in Advance
Yes you can customize the UI Classes or any other class, Like I have customize UILabel Class as UILabelExtended

So I have it set up so when the characters health is < 100 (for testing purposes) it stop the scene and goes to the game over scene.
if (playerDataManager.playerHealth < 100) {
[[CCDirector sharedDirector] replaceScene:[CCTransitionFade transitionWithDuration:3 scene: [GameLogic scene]]];
}
However when the players health drops below 100, it goes to the new scene, but the FPS drops dramatically from 60 to 5.
I get a list of OpenGL error 0x0503 in -[EAGLView swapBuffers] then it stays frozen like that for about 40 seconds, then the FPS unfreeze and goes back out to 60 and I get a list of 2012-07-13 10:37:50.234 Tilegame[93513:10a03] cocos2d: removeChildByTag: child not found!
Then I can continue with the app like normal, going back to the main menu, starting a new game, then recreate the error.

OpenGL error 0x503 means GL_STACK_OVERFLOW, it means you are pushing too many things onto the opengl stack.
I see several instances of pushScene in your code, but no instances of pop anything anywhere. You cannot just keep pushing things indefinitely without popping them, or you will get this error.
We need to what is currently running in your scene, how it has been allocated and how it is released. We also need to know the same information for the new loaded scene GameLogic. Edit your question and add these data.
I have a tiled map. I use cocos2D. The isometric map has an CCLayerPanZoom. For Zooming and scrolling. Now I want to add a tile at the position where I pressed it. It does not work. It is inserting the tile at the wrong position.
Does it has to do with the scaling of the map(Zooming and Scroling which is posible).?

xcode 4.2 ios 5 single view template
I am very new to this ios format and these new features in xcode
Here is all of my code:

I dont know why this is happening
I've run your code through Lindent (a small shell script around the indent(1) program with settings that the Linux kernel developers like; it isn't perfect, but it's a good start).
Once I did this, it was far easier to spot that your series of if (CGRectIntersectsRect(..)) tests aren't actually in any function. They're at the top level of your source.
All statements and expressions must be within a function. (Declarations and global definitions can be at top-level.)
Figure out which function should "own" that series of routines and place them within the function body.
