I am trying to implement a live/score system using cocos2d and box2d. my bodies are box2d bodies which collide as I want them to but the problem is that I have been trying to implement a score system where on each collision a life is removed or reduced from the lives left and after a certain number of collisions(say 3) the game is supposed to stop. On this occasion it doesn't but from the CCLOG I find out that it actually prints out the message I put in to display when the game manager is called but a weird thing is that it calls it forever(see the debugging window below)also it removes the object, "man" from the scene completely on starting the application.
I have a gameManager(singleton) class where in the .h file I have this declared
@interface GameManager : NSObject {
int lives;
}
-(void)removeLives : (int)val;
and in the gameManager.m file I have this method
-(void)removeLives : (int)val
{
lives -=val;
CCLOG(@"YOU HAVE LOST A LIFE MAN");
}
In my main gameLayer.mm file in the update method I have this code
if(kStateColliding){
if (lives > 0) {
man.visible = TRUE;
}
else if(lives <= 0){
[man stopAllActions];
man.visible = FALSE;
[[GameManager sharedGameManager] removeLives:1];
}
}
and the lives is initialised in gameManager init method thus
-(id)init { // 8
self = [super init];
if (self != nil) {
// Game Manager initialized
CCLOG(@"Game Manager Singleton, init");
lives = 3;
}
Also note that I have a "Man" class which is Box2d class.
Am I doing the correct thing? Please can anyone help me out with how to go about implementing this system and where and how to make the appropriate calls.
Thanks.
