Code:
function Update(self)
   if self.parent:GetController():IsState(Controller.PRESS_UP) and self.parent:GetController():IsState(Controller.PRESS_DOWN) then
      local Ge = CreateMOSRotating("Blast");
         Ge.pos = self.pos;
         Ge.vel = self.Vel;
         MovableMan:AddParticle(Ge);
         self.ToDelete = true;
      end
   end
end


you may need to use Controller.HOLD_UP and Controller.PRESS_DOWN (or vise versa), cause this requires to be pressed at the exact same time.

Needing to press both jump and crouch at the same time excludes gamepad users.
Makes me saaaad. :(

so are you using something like this

Code:
function Create(self)
     for i = 1, MovableMan:GetMOIDCount() - 1 do
          local gun = MovableMan:GetMOFromID(i);
          if gun.PresetName == "name of gun" then
               local avgx = gun.Pos.X - self.Pos.X;
               local avgy = gun.Pos.Y - self.Pos.Y;
               local dist = math.sqrt(avgx ^ 2 + avgy ^ 2);
               if dist < 50 then
                    self.gun = gun;
               end
          end
     end
     if self.gun ~= nil then
          local root = MovableMan:GetRootMOID(self.gun.ID);
          if root.ClassName == "AHuman" then
               self.act = MovableMan:GetMOFromID(root);
          end
     end
end

function Update(self)
     if self.parent ~= nil then
          if self.parent:GetController():IsState(Controller.PIE_MENU_ACTIVE) then
               local Ge = CreateMOSRotating("Blast");
               MovableMan:AddMO(Ge);
               Ge.pos = self.pos;
               Ge.vel = self.Vel
               self.ToDelete = true;
          end
     end
end

"root" can't be used as a variable.


Since when??

I have been using root as a variable in all my scripts and haven't had any problems with it?

and yes, you only need to find the actor, to use the script it it still useful to find the gun to get gun position and rotangle if you are making lua bullets?

else this will suffice

Code:
function Create(self)
   for actor in MovableMan.Actors do
      local avgx = actor.Pos.X - self.Pos.X;
      local avgy = actor.Pos.Y - self.Pos.Y;
      local dist = math.sqrt(avgx ^ 2 + avgy ^ 2);
      if dist < 50 then
         self.parent = actor;
      end
   end
end

function Update(self)
     if self.parent ~= nil then
          if self.parent:GetController():IsState(Controller.PIE_MENU_ACTIVE) then
               local Ge = CreateMOSRotating("Blast");
               MovableMan:AddMO(Ge);
               Ge.pos = self.pos;
               Ge.vel = self.Vel
               self.ToDelete = true;
          end
     end
end

Soo you want the gun to:

A. shoot a bullet and if you "right click" with your actor the bullet explodes?
B. or do you want the bullet to find an actor (not yourself) and blow up the actor?
C. or blow yourself up?

I made an example for you, when you fire the gun then right click it turns into pow.
