"Stunning" Enemies?

[Tormentor667]

Is it possible to create a weapon that doesn't do any damage but stun enemies so that they move slower OR stop moving? Custom pain states? Custom states? Please an example if possible Are other propertychanges possible with weapons?

[Risen]

It's possible while doing one damage point... not sure if it's yet possible with 0. Not too long ago it was not possible, but I haven't been keeping up with the recent additions.

the freeze gun in the weapon res wad that freezes the emeny but maby just maby if you play around with it you probly could get an effect that you want

[Jimmy]

He wants to "stun" the monsters, not freeze them into ice.

Have a damagetype called "Stun" and then have a custom pain state that goes like this:

Code: Select all

Pain.Stun
  TROO H 2
  TROO H 25 A_Pain
  TROO H 2
  Goto See    //replace this with Wait to make them stop moving completely

Or somesuch. Untested of course, since I've never used damagetypes before, but modify until it works flawlessly or to your content.

To make them move slower, have them execute a script in this state to reduce their speed.

Code: Select all

Pain.Stun
  TROO H 2 ACS_Execute(539,0)
  TROO H 2 A_Pain
  Goto See

Code: Select all

script 539 ( void )
{
  SetActorProperty(0,AProp_Speed,0.5); //I believe this will reduce them to half-speed, but this may be wrong
}

Hope that helps - I'm double-guessing here, of course - soooo... don't hurt me if it doesn't work.

Enjay made some stun grenades using non damaging ripping projectiles.

Okay, thx first at all jimmy, that helped. Here is what I have tried:

Code: Select all

///////////////////////////////
// ALTERED ORIGINAL MONSTERS //
///////////////////////////////

actor MyZombie : ZombieMan replaces Zombieman

{
    painchance "Freeze", 255

    States {
         Pain.Freeze:
              POSS G 3
    	      POSS G 300 A_Pain
              goto See
     }
}

}

  Select:
    MISG A 1 A_Raise
    loop

    stop
  Spawn:
    LAUN A -1
    stop
  }
}

It is a weapon now (with dummy graphics) that uses a new projectile with the damage type "Freeze" doing exactly 1 damage as suggested by Risen. I can now easily stun the altered Zombieman with that attack. The only problem now is, when I hit it with a different weapon, the stun effect stops and the normal pain state is displayed. Is there anything I can do to make sure that the stun lasts the "frames / duration" that I have set in its state without getting into the normal pain state?

[Ghastly]

I'm 99% sure that 0 damage can't activate a pain state. +AlwaysPain flag for projectiles and bulletpuffs, anyone?

A_ChangeFlag("NoPain", 1) should fix that problem, Tormentor.

[Tormentor667]

Awesome, that worked

[Enjay]

Enjay made some stun grenades using non damaging ripping projectiles.

Yup, specifically the "sonic grenades" in my Burghead thingy. The thrown grenade sits on the floor spewing out short life, zero damage, invisible ripping projectiles in all directions for a few seconds. Any enemy that comes close has a high chance of being put into their pain state. With custom pain states and damage susceptibility, it could certainly be tailored further.

[DBThanatos]

@ghastlyd: I think enjay just said it, but Ill say it myself ( ): Zero damage attacks still makes monsters enter in it's pain states.

@torm: The only way that comes to my mind for the last thing you said, is a check in the main pain state (if you are not using more than the PAIN and Pain.Freeze).

Code: Select all

actor MyZombie : ZombieMan replaces Zombieman

{
    painchance "Freeze", 255
    Health 1500

    States {
         Pain:
              TNT1 A 0 A_JumpIfInventory("StunCheck",1,"Pain.Freeze")
              POSS G 3
             POSS G 4
              goto See
         Pain.Freeze:
              TNT1 A 0 A_JumpIfInventory("StunCheck",1,1)    //if it have at least one, jump the next state so it wont get more infinitely
              TNT1 A 0 A_GiveInventory("StunCheck",10)    //as many as you want the effect lenght
              POSS G 3
              POSS G 3 A_Pain
		  TNT1 A 0 A_TakeInventory("StunCheck",1)
		  Goto Pain
     }
}

Actor StunCheck : Inventory
{
	Inventory.MaxAmount 30
	Inventory.Amount 1
}

In theory this should work, I dont have ZDoom to test in this PC, but I really think it'll work. If not, I think you'll get my idea anyway

[Onslaught Six]

Wouldn't giving an enemy (all enemies?) a Damagefactor "Freeze" 0.5 tag reduce the damage enough to get rid of the 1 point of damage, also?

[Unknown_Assassin]

I'm 99% sure that 0 damage can't activate a pain state. +AlwaysPain flag for projectiles and bulletpuffs, anyone?

Add +RIPPER to projectile, and you can make a monster go into its pain state. Of course, with a damage of 0, it will still have the same health.

With tje +RIPPER flag, the projectile goes through enemies and I don't want this to happen
