Question

So far I have the code

- (void)CreatenewBlock:(int)blockCountToSpawn
{
    for (int i=0; i != blockCountToSpawn; i++) 
    {
        theBlockxCord = arc4random() % 4;
        theBlockyCord = arc4random() % 4;
        NSLog(@"New Block with Cords (%i, %i)",theBlockxCord, theBlockyCord);
    }

}

This loops until it reaches the anount of blockCountToSpawn
This works exactly how I want it to but I want to set theBlockxCord to a new variable each time. So the end result would be something like:

theBlockxCordOfBlock1=2
theBlockxCordOfBlock2=4
theBlockxCordOfBlock3=1
theBlockxCordOfBlock4=3

Instead of theBlockXCord being overwritten each time.

For bonus points, Is there a single way to call of them maybe in an array so I don’t have to keep doing this:

if (theBlockxCordOfBlock1 == 2 || theBlockxCordOfBlock3 == 2 ..etc)
{
   do stuff..
}

You can use C arrays or an NSMutableArray. You will have to convert the ints to NSNumbers before you can add it to the array.

- (void)CreatenewBlock:(int)blockCountToSpawn
{
    NSMutableArray *blockXCoord = [NSMutableArray array]; // Retain it as needed.
    NSMutableArray *blockYCoord = [NSMutableArray array];
    for (int i=0; i != blockCountToSpawn; i++) 
    {
        [blockXCoord addObject:[NSNumber numberWithInt:(arc4random() % 4)];
        [blockYCoord addObject:[NSNumber numberWithInt:(arc4random() % 4)];
    }

    ...
}

if you want to search for 2 then do this

if ( [blockXCoord indexOfObject:[NSNumber numberWithInt:2]] != NSNotFound ) {
    ... do stuff
}

or

if ( [blockXCoord containsObject:[NSNumber numberWithInt:2]] ) {
    ... do stuff
}

EDIT

for ( int i = 0; i < [blockXCoord count]; i++ ) {
    NSPoint point = NSMakePoint([[blockXCoord objectAtIndex:i] intValue],[[blockYCoord objectAtIndex:i] intValue]);

    ... do something with the point.
