Damage per distance

[jpalomo]

Why not suggest a feature to modify a projectile's damage value? That'd give all the flexibility one would really need.

This can already be done in ACS using [wiki]SetActorProperty[/wiki]. You can easily use ACS_ExecuteAlways (in decorate) in combination with SetActorProperty to modify the damage on the fly.

That changes the Random(1,8) damage multiplier though. It's useless for custom formulas.

I'm not a programmer nor do I know anything about ZDoom inner workings, so excuse my ignorance, but couldn't the [wiki]A_WolfAttack[/wiki]'s 'damage over distance' feature be adapted to other attacks?

[Spottswoode]

It's possible but unlikely. A_WolfAttack is a hitscan attack, but there is code designed to affect distance in it. The parameters for that action are very specific, so changing the action to more open parameters is probably better than adapting the code.
I had completely forgotten about this though.....shame on me.

This probably wouldn't work for hitscan, but wouldn't having a projectile start at x health, then do DamageThing(y) every z tics, then at death do A_Explode(Health,smallradius) work?

[Spottswoode]

I've been told that the Gyrojet is a real-world gun whose projectile accelerates the longer it is in flight, thus theoretically doing more damage if it flies farther.

Gyrojet firearms are actually rocket propelled projectiles. They have a much lower velocity than most of the new long range cartridges even at their max.

You can factor up current absolute velocity, and add/subtract to a user variable. ([wiki]Decorate Expressions[/wiki] and [wiki]A_SetUserVar[/wiki] will help you here.) Then, [wiki]A_Explode[/wiki] can be used to deal the actual damage, with the modified damage value passed to it. (The projectile itself can be set to (0) damage.)

How would you do that? I can only seem to put a number in the explosion amount

I think this will help you.
