Question

I have no idea why this code does not work. The whole idea about it is to make the value bigger until it’s bigger than score.

if(score > height && rocketlaunch == false)
{
    @try
    {
         height = [self makebigger:height];
    }
    @catch (NSException *exception)
    {
         height = height + 4000;
    }
    upgradeRocket.center = CGPointMake((rand()%200), -50);
    rocketlaunch = true;
}

-(int)makebigger:(int)heightnr {
  heightnr = heightnr + (1000 * rand() %5);
  if(score > heightnr) {
    [self makebigger:heightnr];
    return heightnr;
  } else {
    return heightnr;
  }
}

Does anyone know how to fix this? Or have a alternative way?

P.S.
The error displayed was:

Implicit conversion of int to id is disallowed with ARC

and

Incompatible integer to pointer conversion returning int from a function with result type id

Thank you in advance.

EDIT:

It works this way thank you very much 🙂

EDIT:

I got a new problem hard to solve:

this gives the error > tread 1 exc bad acces code = 2

Answer 1

change -makebigger:(int)heightnr to - (int)makebigger:(int)heightnr.

You have to specify the return type.

And you have to return something if the condition is true, too.

Until now I didn’t even know it was possible to use no return type. But apparently it is.
