Some sort of array problem
Post: #1
Im not really sure what is going on an array (amebas) isnt holding the last object stuck into it, i think. After the last object is placed in the array, i can get info about it in that same method, but as soon as i try to call its methods from a different method everything is 0 whereas the other 3 objects are fine.
here is my method for loading the objects into the array
i dont think the beginning code matters much skip down the the note that says setup players
lots of stuff in there that has nothing to do with it its basicallly the last loop
the array amebas is the one that is giving me trouble.
ameba has a method called -owner which returns the player that owns it as long as i am in the above method all 4 amebas in the amebas array tell me correctly which player owns them but as soon as its a diffferent method the last one is 0 for everything
here is the method
simple but if i log right before it and get the ameba n's owner it is -1
yes amebas is init'd alloc'd and retain'd at -awakeFromNib
here is my method for loading the objects into the array
i dont think the beginning code matters much skip down the the note that says setup players
Code:
- (void)setupH:(int)h W:(int)w players:(int)p
{
width = w;
height = h;
srand(time(NULL));
[board removeAllObjects];
[players removeAllObjects];
//setup board
int x, y;
for (y = 0 ; y < h ; y++) {
for (x = 0 ; x < w ; x++) {
Tile *tempTile = [[Tile alloc] init];
[tempTile setX:x*32];
[tempTile setY:y*32];
[tempTile setProtein:0];
[tempTile setOwner:0];
if (rand() % (h*w) < (h*w)/3) {
[tempTile setProtein:1];
}
[board addObject:tempTile];
}
}
//setup players
for (x = 0 ; x < p ; x++) {
Player *newPlayer = [[Player alloc] init];
Ameba *firstAmeba = [[Ameba alloc] init];
switch (x) {
case 0:
[firstAmeba setTileOn:0];
break;
case 1:
[firstAmeba setTileOn:w-1];
break;
case 2:
[firstAmeba setTileOn:(w*h)-w];
break;
case 3:
[firstAmeba setTileOn:(w*h-1)];
break;
}
[firstAmeba setStrength:4];
[firstAmeba setSpeed:3];
[firstAmeba setVitality:5];
[firstAmeba setArmor:0];
[firstAmeba setOwner:x];
[amebas addObject:firstAmeba];
[newPlayer addAmeba:firstAmeba];
[newPlayer setProtein:20];
[players addObject:newPlayer];
}
}lots of stuff in there that has nothing to do with it its basicallly the last loop

First thing that stikes out is
So is whats being printed actually what the objects are.
I think id need to see the code for the amoeba class to really know what the problem is.
Code:
NSLog(@"%d %d", n, [[amebas objectAtIndex:n] owner]); // owner
return [amebas objectAtIndex:n]; // not ownerI think id need to see the code for the amoeba class to really know what the problem is.
Sir, e^iπ + 1 = 0, hence God exists; reply!

That -1 should be a 3 and it does the same thing for all accessor methods of the last added object, owner was just an example, the other 3 objects are fine so it isnt the ameba class.
but here it is anyway
its just a bunch of mutator/accessor methods
but here it is anyway
Code:
@implementation Ameba
- (void)setTileOn:(int)n
{
tileOn = n;
}
- (int)tileOn
{
return tileOn;
}
- (void)setStrength:(int)n
{
strength = n;
}
- (int)strength
{
return strength;
}
- (void)setSpeed:(int)n
{
speed = n;
}
- (int)speed
{
return speed;
}
- (void)setArmor:(int)n
{
armor = n;
}
- (int)armor
{
return armor;
}
- (void)setVitality:(int)n
{
vitality = n;
}
- (int)vitality
{
return vitality;
}
- (void)setOwner:(int)n
{
owner = n;
}
- (int)owner
{
return owner;
}
@endits just a bunch of mutator/accessor methods

Ok sorry I dont really see anything wrong.
Is players 4 or 3?

Players 0-2 work fine but the last one in the array (3) is all -1s even if i log it at the end of the mehtod where it is created all 4 are fine, so something is happening to it. But i have no idea what i could try adding another and seeing what it does. Ill do that.
Ok i made it just add an object and it did the same thign the last ogject was the messed up one 3 didnt have any problems. !!!
here is my awake from nib method

Don't alloc and retain, that's causing a memory leak.
Do one of the following but not both:
[[NSArray array] retain]
OR
[[NSArray alloc] init]

here is my new code, does the exact same thing
this gets the same thing also if i change it to
amebas = [[NSMutableArray array] retain];
it gets the same thing as well
Code:
- (void)awakeFromNib
{
players = [[NSMutableArray alloc] init];
board = [[NSMutableArray alloc] init];
amebas = [[NSMutableArray alloc] init];
[self setupH:10 W:20 players:4];
}this gets the same thing also if i change it to
amebas = [[NSMutableArray array] retain];
it gets the same thing as well
