I'm wondering if it's possible to make a powerup that spawns something (like a spam of projectiles or an explosion) every X tics while it lasts?

Use an ACS script.

An exemple would be nice if possible. That is a well done one, unless its as basic as an inventory check so it spawns something. But wouldn't even know how to do so at a player's position.

Subclass this in decorate http://zdoom.org/wiki/Classes:CustomInventory
Then make an ACS library http://zdoom.org/wiki/Libraries
In the ACS library, create a script like this one (this script starts and executes some code every second for 10 seconds): Then put an ACS_ExecuteWithResult(666) in your CustomInventory thing in Pickup: state (if the powerup is used instantly) or Use: state (if it's stored in the inventory).

Player position can be received with GetActor# family of functions.
Spawning is done by the Spawn family (see the bottom of this page for other spawn-related functions).

Neat, ill try it out whenever i can!

Uh, i would like to ask another question, if the spawn is done via a script and not via a decorate or an actor itself, wouldn't it result the projectile to hurt the user of the projectile as well and its allies?

EDIT: I tried a work around in the meantime of an inventory item that loops its effect for as long as the powerup is detected on the player but i seem to be running out of luck... Only does it once you pick up the item then it stops

script 666 (void)
{
  for (int i = 0; i < 10; i++)
  {
    // spawn something here.
    Delay(35);
  }
}

Don't know if i'm doing this right but nothing seems to be spawning: I'm pretty awful when it comes to ACS ^^'

EDIT: Figured its because i forgot to put #include "zcommon.acs", tho what is weird is that instead of counting seconds it counts ticks, like it only lasts 10-30 tics. And it also hurts allied players as i feared.

EDIT2: I figured a work around using ZZYZX's script (Will remember to give him a special thanks if this project gets finished), instead of spawning something every X tics, it gives an item to the player that spawns something every X tics. So it doesn't affect the player and nor allied players :D. Thanks for the help guys!
