Gun Script

From Second Life Wiki
Revision as of 15:21, 7 December 2012 by Omei Qunhua (talk | contribs) (Rewrote attach and on_rez events and removed llResetScript(). Assignment of computed perm mask to permFlags can't be done in global definitions. Pointless asking if it's attached to owner!)

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. Someone simplified this without saying so and it doesn't work i'm looking for why.

<lsl> float bulletVelocity = 15.0; float pauseBetweenShots = 0.30; string shootingSound = "gun"; string shootingAnimation = "hold_R_bazooka"; string inventoryItemWhichIsBullet = "bullet 1.0"; integer permFlags;

default {

   on_rez(integer start_param)
   {
       if (!llGetAttached() )       llOwnerSay("Attach me to your right hand and enter mouselook to fire!");          
       else                         llPreloadSound(gunsound);
   }
   attach(key id)
   {
       if (id == NULL_KEY)
       {
           llStopAnimation(shootingAnimation);
           llReleaseControls();
       }
       else    llRequestPermissions(llGetOwner(), (permFlags = PERMISSION_TRIGGER_ANIMATION | PERMISSION_TAKE_CONTROLS | PERMISSION_ATTACH | PERMISSION_TRACK_CAMERA) );
   }
   changed(integer change)
   {
       if (change & (CHANGED_OWNER | CHANGED_INVENTORY))           llResetScript();
   }
   run_time_permissions(integer perm)
   {
       if (perm & permFlags)
       {
           llAttachToAvatar(ATTACH_RHAND);
           llTakeControls(CONTROL_ML_LBUTTON, TRUE, FALSE);
           llStartAnimation(shootingAnimation);
           llOwnerSay("Gun is ready. Enter mouselook to fire!");
       }
   }
   control(key owner, integer level, integer edge)
   {
       vector cameraPos = llGetCameraPos();
       rotation cameraRot = llGetCameraRot();
       if ((level & CONTROL_ML_LBUTTON) == CONTROL_ML_LBUTTON)
       {
           if ((edge & CONTROL_ML_LBUTTON) == CONTROL_ML_LBUTTON)
           {
           //  play sound at max volume
               llPlaySound(shootingSound, 1.0);
               llRezAtRoot(inventoryItemWhichIsBullet,
                   cameraPos + <1.5, 0.0, 0.0>*cameraRot, bulletVelocity*llRot2Fwd(cameraRot), cameraRot, 10);
               llSleep(pauseBetweenShots);
           }
       }
   }

} </lsl>
