Ok you need to research and play more :p
Ill give you a quicki on whats what
Hit is the damage it does, You will see no Effect on Granades as if you hit someone direct it kills them,
You would need to increase the Splash on it to do something like this
model WHAT THE GUN IS
hit THE DAMAGE THIS CAUSES
indirectHit 18
indirectHitRange MORE LIKE SPASH DAMAGE "turn this up on a gun to 5000 and fire lol you will see"
typicalspeed SPEED IT TRAVELS
cost 40
simulation EFFECTS FOR THE WEAPON
simulationStep 0.050000
soundHit EFFECTS FOR THE WEAPON
soundEngine EFFECTS FOR THE WEAPON
CraterEffects EFFECTS FOR THE WEAPON
explosionEffects EFFECTS FOR THE WEAPON
visibleFire I THINK THIS IS THE TRAIL OR THE EXPLOSION OR SOMETHING IT LEAVS,
audibleFire 0.250000
visibleFireTime LOOK IT UP, SEARCH THE VALUE NAME
Some of them may be wrong correct me if the case,
when i get home i may upload the file i have that tells you what each value does,
My Advise, if have fun with it,
Do extrem stuff so increase vaules to like 5000 and then see what it does, when its visable you know you have done something right,
All i did, was sit there and increase the values on rockers and bullets to a realy high number when ingame tested as seen what it did, wrote it down and moved onto the next,
i hope this helps you, if not sorry
thanks
Dave
