Gun Script

From Second Life Wiki
Jump to: navigation, search

Uses tons of useful functions and a great example for those starting out. I've had tons of fun with this and all its variants i've made in my time here in Second Life. Obviously only can be used were you can rez and run scripts. Corrected and improved.

float   gVelocity   = 15.0;
float   gReloadTime = 0.30;
string  gShootSound = "gun";
string  gShootAnimation = "hold_R_bazooka";
string  gBullet = "bullet 1.0";
integer gPermFlags;

    state_entry()
    {
        //  sanity check
        if (llGetInventoryType(gBullet) != INVENTORY_OBJECT) {
            llOwnerSay("This needs a physical object called " + gBullet + " in it to work");
            return;
        }
        gPermFlags = PERMISSION_TRIGGER_ANIMATION | PERMISSION_TAKE_CONTROLS | PERMISSION_TRACK_CAMERA;
 
        if ( llGetAttached() )
            llRequestPermissions(llGetOwner(), gPermFlags);

            llSleep(gReloadTime);
