Adding a game over scene - iphone

Question

I want to add this game over scene to this game that I am trying to do for my homework, and I seem to not have it where if you kill the target the game over scene will pop up. I tried putting my code in every line and see if it will finally work but no it didn't. So now I have to ask for some help.
. m file
- (void)addTarget10 {
Boss *target10 = nil;
if ((arc4random() % 2) == 0) {{
target10 = [WeakAndFastBoss9 boss9];
}} else {
target10 = [WeakAndFastBoss9 boss9];
}
[[SimpleAudioEngine sharedEngine] playEffect:#"lastboss.mp3"];
// Determine where to spawn the target along the Y axis
CGSize winSize = [[CCDirector sharedDirector] winSize];
int minY = target10.contentSize.height/2;
int maxY = winSize.height - target10.contentSize.height/2;
int rangeY = maxY - minY;
int actualY = (arc4random() % rangeY) + minY;
// Create the target slightly off-screen along the right edge,
// and along a random position along the Y axis as calculated above
target10.position = ccp(winSize.width + (target10.contentSize.width/2), actualY);
[self addChild:target10 ];
// Determine speed of the target
int minDuration = target10.minMoveDuration;
int maxDuration = target10.maxMoveDuration;
int rangeDuration = maxDuration - minDuration;
int actualDuration = (arc4random() % rangeDuration) + minDuration;
// Create the actions
id actionMove = [CCMoveTo actionWithDuration:actualDuration position:ccp(- target10.contentSize.width/2, actualY)];
id actionMoveDone = [CCCallFuncN actionWithTarget:self
selector:#selector(spriteMoveFinished9:)];
[target10 runAction:[CCSequence actions:actionMove, actionMoveDone, nil]];
target10.tag = 1;
[_targets addObject:target10];
}
-(void)gameLogicboss9:(ccTime)dt {
[self unschedule:_cmd];
[self addTarget10];
}
- (void)updateboss9:(ccTime)dt {
CGRect projectileRect = CGRectMake(projectile.position.x - (projectile.contentSize.width/2),
projectile.position.y - (projectile.contentSize.height/2),
projectile.contentSize.width,
projectile.contentSize.height);
BOOL bossHit = FALSE;
NSMutableArray *targetsToDelete = [[NSMutableArray alloc] init];
for (CCSprite *target1 in _targets) {
CGRect target1Rect = CGRectMake(target1.position.x - (target1.contentSize.width/2),
target1.position.y - (target1.contentSize.height/2),
target1.contentSize.width,
target1.contentSize.height);
if (CGRectIntersectsRect(projectileRect, target1Rect)) {
[targetsToDelete addObject:target1];
bossHit = TRUE;
Boss *boss = (Boss *)target1;
boss.hp--;
if (boss.hp <= 0 ) {
[targetsToDelete addObject:target1];
}
break;
}
}
for (CCSprite *target in targetsToDelete) {
[_targets removeObject:target];
[self removeChild:target cleanup:YES];
_projectilesDestroyed++;
if (_projectilesDestroyed > 2) {
}
}
if (bossHit) {
//[projectilesToDelete addObject:projectile];
}
[targetsToDelete release];
}
-(void)spriteMoveFinishedboss9:(id)sender {
CCSprite *sprite = (CCSprite *)sender;
[self removeChild:sprite cleanup:YES];
if (sprite.tag == 1) { // target
[_targets removeObject:sprite];
} else if (sprite.tag == 2) { // projectile
[_projectiles removeObject:sprite];
} }
This the game over scene I want to add when target 10/ boss 9 is killed
GameOverScene *gameOverScene = [GameOverScene node];
[gameOverScene.layer.label setString:#"You Lose"];
[[CCDirector sharedDirector] replaceScene:gameOverScene];
Right now my other game over scene is when the sprite is moved passed screen.If you need me to answer any questions feel free to ask.

Answer 1

For scene replace you try this for your game code..
First Add this code to your GameOverScene class
+(CCScene *) scene
{
// 'scene' is an autorelease object.
CCScene *scene = [CCScene node];
// 'layer' is an autorelease object.
GameOverScene *layer = [GameOverScene node];
// add layer as a child to scene
[scene addChild: layer];
// return the scene
return scene;
}
Make your GameOverClass is subclass of CCLayer,
Than when You want to change scene do this
[[CCDirector sharedDirector] replaceScene:[GameOverScene scene]];

Answer 2

Ok, so you have to create a new scene. This can simple be done using File->New File and make it a subclass of NSObject. You then change the subclass to an CCLayer. As a test, you can just copy your code from the hello world layer. Next, just import the new class in your helloworld layer class and create a instance of it. Then in a method use [[CCDirector sharedDirector] replaceScene:sceneName];
