Thanks for the script, it only works when the object is placed on the ground
though.
Here is something strange though...I turned land damage "on", and shot my
gun at another avatar, and the gun DID DAMAGE...but to me! LOL
Every time I shoot it does damage to me...now if I can just figure out "how"
I may be able to get guns to work in OpenSim.
here is the script I am using;
// Gun script
// John Linden
// where the gun attaches itself if you click on it
// switch this to ATTACH_LHAND if you are left-handed
integer gAttachPart = ATTACH_RHAND;
string INSTR_HELD_1 = "Enter Mouselook (press 'M') to shoot me.";
string INSTR_HELD_2 = "Right-click and choose 'Detach' to take me off.";
string INSTR_NOT_HELD_1 = "To wear and use me, right click and choose";
string INSTR_NOT_HELD_2 = "Acquire -> Attach -> Right Hand.";
string INSTR_NOT_OWNER_1 = "To use this gun, take it (right-click and
choose 'Take'.)";
string INSTR_NOT_OWNER_2 = "Then, drag it from your inventory onto
yourself.";
// this is a permission combination we check for many times
// I define it here so we don't have to keep typing it
// guns need to take controls, attach themselves, and possibly
// trigger animations
// NOTE: since I can't initialize to an expression (even if it is
// all constants), this moved to default { state_entry() }
integer gDesiredPerm;
// Indicates whether wearer has yet given permission
integer gHavePermissions;
// Bullet travel speed
float gBulletSpeed = 45.0;
// when we last fired a shot
float gLastFireTime = 0;
// how long it takes to reload when tapping
float gTapReloadTime = 0.05;
// how long it takes to reload when holding
float gHoldReloadTime = 1.0;
// how long it takes when we're out of ammo
float gOutOfAmmoReloadTime = 1.4;
// how many shots before reload is necessary
integer gAmmoClipSize = 6;
// how much ammo we have right now
integer gAmmo;
// HACK: how far away the eye is from the avatar's center (approximately)
vector gEyeOffset = <0.0, 0.0, 0.84>;

I modified it to have smoke when I shoot, so I wonder why it does damage to
me when I shoot and how I can make it damage the other avatar instead?
any suggestions?
