[Question] Lifesteal Attack for Monsters?

[RV-007]

Is there some script/code that allows monsters to be vampires and stuff like that? The best I can think of is the PowerDrain and its PowerupGiver inventory. I can't really tell if it really works for monsters so that's why I asked here.

It should. Might as well test it.

[Blue Shadow]

Well, in my tests it didn't seem to have any effect on monsters.

My guess it's a player-only powerup.

[NeuralStunner]

I remember looking at that, and don't recall any player-specific code.

Since puffs can have Death, XDeath, and Crash states that they jump to depending on whether they hit level geometry, bleeding targets, or non-bleeding targets respectively, you could use those on a puff to determine when to "steal" life. In the puff's XDeath state you'd run a script that added to the shooter's health.

Monster melee attacks don't use puffs.

[amv2k9]

Monster melee attacks don't use puffs.

Yeah... Well, you can just use a hitscan attack/projectile attack as a melee attack, in combination with things like MeleeThreshold and A_JumpIfCloser.

http://zdoom.org/wiki/A_CustomPunch
A_CustomPunch (int damage [, bool norandom [, int flags [, string pufftype, [float range[, float lifesteal]]]]]) is one statement (other than PowerDrain) that deals with lifesteal. I don't think that there is a monster attack that directly allows lifesteal. This is not much to get monsters to lifesteal targets, but I thought I put this up here.

Puff works too, in fact, it might be a automated spawn of one actor. I guess there is some script to have monsters to use PowerDrain.

There is also DamageType value DrainLife, but I have yet to use this yet.

[XutaWoo]

That's for players, RV. It wouldn't work with monsters.

[RV-007]

There is a LifeDrain value for the DamageType actor property, but I am not sure if that would work for melee monsters (possibly for range monster) unless I used those Archvile statements (still not melee, but close enough). Still need to try out the string Pufftype later on for both melee and range.
