(SOLVED)Powerup that spawns something as it lasts?

[FranckyFox2468]

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):

Code: Select all

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

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!

[FranckyFox2468]

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

Don't know if i'm doing this right but nothing seems to be spawning:

Code: Select all

script 600 (void)
{
  for (int i = 0; i < 30; i++)
  {
    str class = "StarmanAOE";
       do {
     delay(1);
     int x = GetActorX(0);
     int y = GetActorY(0);
     int z = GetActorZ(0);
	 int angle = GetActorAngle(0);
 
   } until (Spawn(class, x, y, z, 0, angle));
    Delay(1);
  }
}

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!
