Pause menu help... noobish!

[aidenfry]

Hey all, brand new to the site, and fairly new to coding.

I am just working on a tower defense game, and atm I am incorporating an RPG element where the player can upgrade their towers in a separate menu.

What I am doing is to pause the game, load the upgrade layer on top of the game screen, then the player can choose their upgrades, after which the layer will disappear and the game will resume.

Where its falling down is removing the layer after the player has chosen their upgrades.

Here is what im doing:

-(void)upgradeSceneLoad
{
ccColor4B c = {255,255,255,0};
upgrademenu = [[[UpgradeLayer alloc]initWithColor:c]autorelease];
[self.parent addChild:upgrademenu z:10];


[[CCDirector sharedDirector] pause];
}

+(void)upgradeSceneRelease
{
[self.parent removeChild:upgrademenu cleanup:TRUE];
[[CCDirector sharedDirector] resume];
}


and in UpgradeScene.m

- (void)healthUpgradeid)sender
{
[MachineGunTower upgradeHp];
[Tutorial upgradeSceneRelease];
}

------------
Because upgradeSceneRelease is accessed from the UpgradeScene class, i'v had to make it a +(void) rather than a -(void). This change now means that I get an error on this line
[self.parent removeChild:upgrademenu cleanup:TRUE];

saying that the member reference is a pointer and maybe i want to use ->parent instead of .parent. Either way it doesn't work.

So, can anyone see where I am going wrong / other ways of doing this.... it should be very simple right???
Thanks
Aiden

Thanks for anyone who looked into this issue.
I have worked out a way around it (although it still might not be the bst way...)


What i Did was too remove
+(void)upgradeSceneRelease entirely

and change the upgrade function in the upgradeScene class too

- (void)healthUpgradeid)sender
{
[MachineGunTower upgradeHp];
//[Tutorial upgradeSceneRelease];

[self.parent removeChild:self cleanup:TRUE];
[[CCDirector sharedDirector] resume];
}

.... mybad!
Thanks all

also make sure that you call

[super onExit];

in the layer when you want to pause it and display another layer on it. This ensures that any touches will not happen on that paused layer.

And when you want to unpause it, just use:

[super onEnter];
