Stopping Power
(1/1)
Khain:
I am making a weapon, and I'm trying to make it Slow down the player when he's shot.

Well isn't working, and when I set it to %obj, it's applied to me.

If anyone can help me it would be very cool.

Is WeaponImage::onHitObject even a function? I've always used Projectile::onCollision
Change the condition to if(%col.getClassName() $= "Player")
pushDatablock should be setDatablock

Remember when something doesn't work, always check the console. It may show errors on exec, and in this case, when you shot someone, it would at least show that pushDatablock doesn't exist

Looks like one of those crazy raycast weapons that have become so popular.
Space Guy:
(Headcrab Zombie:)

push/popDatablock is a custom function I made for adding/removing player types on a stack to avoid errors like the Old-School Rifle making everybody a Standard Player from the minigame rather than e.g. team settings, custom class settings.

WeaponImage::onHitObject is part of my raycast weapons system, it's not a standard function. (The Hammer and Wrench do use a similarly named one, though)

(Khain:)

With the push/popDatablock, are you actually executing the AltDatablocks file?

The problem you're getting is missing the %slot argument to onHitObject, it's trying to check if "weapon slot 0" is a player/apply datablocks to it. Use BigKillImage::onHitObject(%this,%obj,%slot,%col,%pos,%normal,%shotVec,%crit).

onHitObject is what happens when the shot connects with anything, but it'd be better to use BigKillImage::onRaycastDamage (same arguments as onHitObject) as that's when it actually should hurt something. It's the equivalent of editing Projectile::damage versus Projectile::onCollision.
