Fastprojectiles w/ damage falloff

[Se7eNytes]

Is it possible for an fastprojectile's damage to reduce in games like Wolfenstein 3D or most modern games' hitscan weapons?

Hacky method: send several projectiles, without any spread. Make them of different types, all derived from each other through inheritance.

Use code this form:

Code: Select all • Expand view

Actor BulletThatGoesABitFarther : BulletThatStopsAfterAWhile
{
    States
    {
    Spawn:
        BULL AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA 1
        Goto Super::Spawn
    }
}

The number of A in the spawn state determines how long it exists, and therefore, how long it travels. The first class should be the one that travels the least, then you can just copy/paste the exact same code, changing only the name of the bullet actor and its parent, to get even increments in this way.

Shoot all of these projectiles at once and without any sort of variance (you can use args[] or user variables if you do want random spread, compute it once and use the same values for each projectile) so that they'll overlap and just disappear when they run out of their range. There will be gradually less bullets, and therefore gradually less damage.

Alternate method:

• Fire a single projectile.
• Give it Damage (0).
• Include an arg or user var that decreases each tic.
• If the variable drops to zero, have the missile terminate itself.
• On impact, pass the variable to A_Explode, give it a radius/fulldamageradius slighly larger than the projectile's size, and make it not hurt the shooter.
• Make sure it has the FORCERADIUSDMG flag, so it can actually hurt explosive-immune bosses and such.

(Incidentally, this method also foils species projectile immunity, so it would more closely resemble a hitscan.)

A hitscan can also use the A_Explode method, but would need the PUFFGETSOWNER flag a large number of A_JumpIfCloser calls to determine how far it is from the shooter.

I'll give these methods a try soon, thanks!

I have two questions:

• Is there a way to make the damage not fall below a minimum value?
• I should have asked this earlier, but how do I use an Arg?

A_JumpIf

A_SetArg, Args[] Decorate Expression.
