Getting attacking player TID/Pointer (Zandro-compatible)

[ConflagratedCanine]

So I'm completely reworking an existing system for a multiplayer mod, one that would benefit significantly from being able to give inventory items to a player when they attack another.
Previously, I assumed A_GiveToTarget in a painstate would work the same way as it does in a deathstate: this is not the case, and I may have questioned if I was suffering from mild psychosis after producing no results.

I considered using the weapon code as players are the only bleeding actor in the game, but unfortunately all of my weapons, uh, "explode" as a means of simulating swing arcs - As far as I know, I can't trace a successful 'hit' from those back to the attacker.

I might need some help chewing this one out.

It does if you use the flag +QUICKTORETALIATE on the playerpawn actor.
By the way, for the flag to correctly work, make sure the playerpawn actor doesn't have the FRIENDLY flag set otherwise it will break (I ran into this issue myself previously).
This of course will work in 3.0.
One last thing, make sure in the decorate code that whatever you want to do with the pointer is done at the same time the pain state is entered (using stuff like acs_executewithresult) that way you can be sure the pointer will remain untouched by other parts of the engine (I heard there were some issues in the past with the target pointer, can't be 100% sure).
My memory could be playing tricks on me, it's been so long, tell me if this works out for you.

... I just gave all the weapons LOF/LOS checks so I can award inventory items for attempted strikes, as well. I'm going to add your suggestion and see if I can work it in for some extra flexibility.
