Hey I was wondering if someone could help me with the coding of making the four original power ups into "power downs" (negative power ups)
double points = half points (earn half as many points as normal)
max ammo = clip unload (unload the clip of the gun everyone is currently holding, NOT both weapons)
insta kill = infinite kill (zombies have double health)
nuke = point nuke (lose 10% of your points)

Somebody helped me make the clip unload powerdown, but I still need the other 3.
Here is the code for clip unload if anyone wants to use it: http://pastebin.com/PzdaJiAW
Also I need a way for the person who picks up the power up to not be affected by it.

To make everyone affected except the one who grabs it get the play who touched it (I think this is done in zombiemode powerups and with a little modification it will do the job) and then just thread the effect on the other players. And I'd do a check for 1 player, otherwise it would be pointless on solo.

or detect and pass the player that touches it to a function that ignores that player

like :

function_to_call( player )
{
  players = get_players();
  for ( i = 0; i < players.size; i++ )
  {
    if ( player == players[ i ] )
    {
      continue;
    }
    else
    {
      // Thread here
    }
  }
}

To make everyone affected except the one who grabs it get the play who touched it (I think this is done in zombiemode powerups and with a little modification it will do the job) and then just thread the effect on the other players. And I'd do a check for 1 player, otherwise it would be pointless on solo.

I don't know how to do that. And I don't need the solo check because this is a coop only mod

Solo Grief? That sounds like fun

Edit: I realised maybe you hadn't seen his Grief mod topic, so probably you didn't know that

To make it work on a specific player all you need to do is call it on the entity that is within the range.
So: players thread powerup();

I still don't know exactly what to do

you could probably just open the effects in the effect editor and change it to a red colour and then just make it call that fx

lol, he means the actual effect, not the colour bro

The fx color is simple yo change
