Question about functions with ints

[James (Aka: The Geek)]

Riddle me this,lets say I am making a game (I'm not right now but I am curious about how this would work)
and I have a function like this:

int red;
int blue;
int green;

function addsome (){
int ran random (2)
if (ran==0)red==1;
if (ran==1)red==2;
if (ran==2)red==3;
Ã,  }

I need to use this function many times but, often times I
need to do this with other ints.Ã,  :o
Is there any I could do this without having to write many functions and instead do something like this:

function addsome(int,red);
function addsome(int,blue);
function addsome(int,green);

Please explain to me how to do this

Well, you're kind of there ... Use an int in the function declaration, to specify which int is to be changed, something like:

Code: ags

function AddSome (int which) {
  int ran = 1 + Random(2); // I.e. will be 1, 2 or 3
  if (which == 0) red = ran; // NOTE: Single '=' for setting values. Only use '==' for checking.
  else if (which == 1) blue = ran;
  else if (which == 2) green = ran;
  // And so on for any other ints you may have
}

To make it less confusing, you could make an enum for the int names, e.g. (in the Global Header):

Code: ags

enum IntNames {
  eIntRed,
  eIntBlue,
  eIntGreen
  // And so on
};

And then the function would be:

Code: ags

function AddSome (IntNames which) {
  int ran = 1 + Random(2);
  if (which == eIntRed) red = ran;
  else if (which == eIntBlue) blue = ran;
  else if (which == eIntGreen) green = ran;
  // And so on
}
