How to make Alt fire effect player?

[Theshyguy489]

I'm making a few weapons that I need an alt-fire that effects the player. I don't know the proper commands.

I need one weapon to toggle Light amplification visor power up and the other to toggle an increase of running speed.

Is this something complicated or simple?

It's simple if you know how to zScript. In the weapon's Altfire state, you would simply check if the owner has the inventory and use it, or give him the powerup directly.
