UE1 - UT Need help choosing a random pawn

[Rajada]

I can't seem to find anything that uses this already for this engine, but I need help making code that chooses a pawn at random in a mutator (probably just playerpawns). Any suggestions?

Nevermind, I found something similar enough in my game's (NAB) source code to adapt for this use. I doubt I'll ever use all 64 player slots, and ended up with this:

PlayerPawn PP[64];
var byte NumPPS;
var PlayerPawn P;

function PostBeginPlay()
{
	SetTimer(15,True);
	Super.PostBeginPlay();
}
simulated function timer() 
{
	foreach AllActors( class 'PlayerPawn', P )
		{

		PP[NumPPS++] = P;
		if( NumPPS==ArrayCount(PP) )
			break;
		}

	P = PP[Rand(NumPPS)];
}

Try this function on:

function Pawn GetRandomPlayer()
{
  local Pawn N;
  local PlayerPawn Dest;
  local Pawn Candidate[32];
  local int num;

  for (N=Level.PawnList; N!=None; N=N.NextPawn)
  {
    Dest=PlayerPawn(N);
    if (Dest!=None && Dest.bIsPlayer && !Dest.PlayerReplicationInfo.bIsSpectator)
    {
      if (num<32) Candidate[num] = Dest;
      else if (Rand(num) < 32) Candidate[Rand(32)] = Dest;
      num++;
    }
  }

  if(num==0) return None;
  return Candidate[Rand(Min(32,num))];
}

Fortunately my method works, but thanks for replying anyway.

You should avoid ForEach AllActors every time it is possible. Iterating the pawn list like I showed you is much faster and uses less system resources by far.

I'll keep that in mind because I'm going to be remaking it as a larger mutator. This version is just a proof of concept, thanks for the help.
