Health wasn't full, I placed a hurt zone in the corner to test functionality just to be sure.
Anyway, worked just fine. However, I noticed that the hitbox of the entity may be a bit botched--a fixable problem, of course.
I was wondering if this charger could be adjusted to function like the health/HEV chargers in Half-Life: Source (the action key--usually, the Enter key--activates it, and it will charge your health to a limited extent before cutting out--and will refuse to charge your health further if it's full. There should also be a way for it to not continue to be used beyond its limit once the player's health has been reached or the recharge limit has been hit--in which case, a sound should be played and the texture should be changed).
I'm inexperienced with FPI scripting... so I'll just play n00b here and ask if you guys can show me how?
