Why is my variable not being set in Cocos2d? - cocos2d-iphone

Question

In my GameManager singleton object I create:
// Load levels
// Create array property to store level objects
self.levels = [[[NSMutableArray alloc] init] autorelease];
//Create 2 level objects with spawnRates
Level *level1 = [[[Level alloc] initWithLevelNum:1 spawnRate:10000 bgImageName:#"Icon.png"] autorelease];
Level *level2 = [[[Level alloc] initWithLevelNum:2 spawnRate:10000 bgImageName:#"Icon.png"] autorelease];
Level *level3 = [[[Level alloc] initWithLevelNum:3 spawnRate:80 bgImageName:#"Icon.png"] autorelease];
Level *level4 = [[[Level alloc] initWithLevelNum:4 spawnRate:80 bgImageName:#"Icon.png"] autorelease];
Level *level5 = [[[Level alloc] initWithLevelNum:5 spawnRate:2 bgImageName:#"Icon.png"] autorelease];
Level *level6 = [[[Level alloc] initWithLevelNum:6 spawnRate:1 bgImageName:#"Icon.png"] autorelease];
//Put level objects into array property
[_levels addObject:level1];
[_levels addObject:level2];
[_levels addObject:level3];
[_levels addObject:level4];
[_levels addObject:level5];
[_levels addObject:level6];
//Set current level index to 0
self.curLevelIndex = 0;
And further down the line, I implement methods to be called by layers like so:
- (Level *)curLevel {
NSLog(#"curLevelIndex is %d", _curLevelIndex);
//returns object at current level index where at start, first slot [0] = spawnrate = 1
return [_levels objectAtIndex:_curLevelIndex];
}
- (void)restartGame {
_curLevelIndex = 0;
[self nextLevel];
}
- (void)levelComplete {
NSLog(#"curLevel spawnRate is %d", [self curLevel].spawnRate);
//Increase currentlevelindex
_curLevelIndex++;
if (_curLevelIndex >= [_levels count]) {
_curLevelIndex = 0;
NSLog(#"resetting levels");
} else {
//make it faster
//NSLog(#"current level %d", [[_levels objectAtIndex:_curLevelIndex].spawnRate ];
NSLog(#"new level %d", _curLevelIndex);
}
}
Please excuse all the NSLogs but im going crazy trying to find out why my spawnRate is not being changed. In my game's update method I do this:
if (timeSinceLastRateBump > 3) {
NSLog(#"DIFFICULTY INCREASES NOW>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>");
[[GameManager sharedGameManager] levelComplete];
timeSinceLastRateBump = 0;
}
And this is called every second more or less. Now Im getting this in my NSLog:

Which proves curLevelIndex is increasing from 0 to 1 to 2. But the spawnRate remains at 0. Why?

Answer 1

in your levelComplete routine, instead of :
NSLog(#"new level %d", _curLevelIndex);
do :
Level* current = [self curLevel];
NSLog(#"current level no : %d , spw rate : %f",current.levelNumber,current.spawnRate];
// *** WAG for the getters.
and breakpoint on log. If current is nil, figure that out. If not, inspect the var and look at the spawn rate in that object.

Answer 2

in the code:
NSLog(#"curLevel spawnRate is %d", [self curLevel].spawnRate);
%d is used for a double value, not a float. change it to %f.
