ProjSpawnFuncActorFast is a simpler version of [BasicFastProjectile](<https://mm8bdm.notion.site/BasicFastProjectile-46b999123b704437822c07226eff796d>). It’s a simple actor inheriting from [FastProjectile](<https://zdoom.org/wiki/Classes:FastProjectile>) with no new properties aside from the fact that it activates all spawn functions for projectiles. This actor is extremely bare-bones and should only be used when you specifically want a projectile that triggers spawn functions, but has different requirements from BasicFastProjectile.

Similar to BasicFastProjectile, this should only be used for projectiles at or above speed 60. If you want a projectile that’s slower, consider [ProjSpawnFuncActor](<https://mm8bdm.notion.site/ProjSpawnFuncActorFast-64bc35994ac0467a99df41fd82844df1>) instead.

DECORATE Definition

<aside> 🚨 Wait! Stop! Before you copy this actor's definition into your mod, remember the following things:

• You do not need to copy this actor, since it is already defined.
• In fact, it's not just useless, it's actually harmful as it can cause problems.
• If you want to use it as a basis, using inheritance is the way to go.
• The actor definitions here are put on the wiki for reference purpose only. Learn from them, don't copy them into your mod. </aside>

}

Custom Properties

These are user variables that can be added to the actor for various effects. You do not need to give them a value, they just must be defined.

• var int user_NoTranslation - Disables projectile team colors on this actor

• var int user_TranslateWhiteColors - Allows projectile team colors to recolor white.

• var int user_TranslateBlackColors - Allows projectile team colors to recolor black.

• var int user_PierceRipper - Makes it so that this actor only does damage once to another actor. The actor being damaged must have [+USEDAMAGEEVENTSCRIPT](<https://wiki.zandronum.com/DECORATE#:~:text=USEDAMAGEEVENTSCRIPT>), like players already do.

  • You can fine-tune the number of times that this actor deals damage by using A_GiveInventory("PierceRipperLimit", x) in the Spawn state of the actor.

• var int user_DamageKill - Makes it so that this actor only does damage once before entering Death state. The actor that is being damaged must have [+USEDAMAGEEVENTSCRIPT](<https://wiki.zandronum.com/DECORATE#:~:text=USEDAMAGEEVENTSCRIPT>), like players already do. The actor with this flag must also have reactiontime set.

  • The amount of times that this actor can deal damage before perishing is determined by the reactiontime value. A projectile with reactiontime 3 will only be able to damage 3 times to any players before dying.

• var int user_noOwnerDamage - If the actor has the +SHOOTABLE actor flag, the [+USEDAMAGEEVENTSCRIPT](<https://wiki.zandronum.com/DECORATE#:~:text=USEDAMAGEEVENTSCRIPT>) actor flag, and a health value, this property will prevent the owner of the actor as well as their teammates from dealing damage to it.

Example

Here is a modified Wheel Cutter actor from MM8BDM. It is used to “instantly” place Wheel Cutter’s launched projectile 96 units forward.

actor WheelCutterLaunchPlacerSimple : ProjSpawnFuncActorFast
{
    PROJECTILE
    Obituary "$OB_WHEELCUTTER"
    Damagetype "WheelCutter"
    scale 2.5
    Radius 10
    Height 10
    Damage (20)
    Speed 96 // WEPC_10WC_SAWRADIUS
    States
    {
		    Spawn:
		        TNT1 A 0
		        TNT1 A 0 A_SpawnItemEx("WheelCutterLauncher", 0, 0, 0, momx/WEPC_10WC_SAWRADIUS, momy/WEPC_10WC_SAWRADIUS, momz/WEPC_10WC_SAWRADIUS, 0, SXF_ABSOLUTEMOMENTUM|SXF_MULTIPLYSPEED)
		        stop
		    Death:
		        TNT1 A 0 A_SpawnItemEx("WheelCutter", 0, 0, 0, 1.0, 0, 0, 0, SXF_MULTIPLYSPEED)
		        TNT1 A 10
		        stop
    }
}
