Post Need some lua to actor (LaserHead)
I need lua for the actor, are follows:
Actor would have a laser sight, as Techion nanorifle, where you look, there is laser, it better to be from the head and not from body.

Experimental code:
Code:
dofile("Base.rte/Constants.lua")
require("Actors/AI/NativeHumanAI")
function Create(self)
   self.AI = NativeHumanAI:Create(self);
   self.laserTimer = Timer();
   self.laserLength = 800;
   self.laserSpaceCheck = 5; -- For optimization purposes. Smaller value means a more accurate but slower check.
   self.laserDensity = math.ceil(self.laserLength/self.laserSpaceCheck);
end
function Update(self)
   if self.laserTimer:IsPastSimMS(50) then
      self.laserTimer:Reset();
      if self:GetController():IsState(Controller.AIM_SHARP) and self:IsPlayerControlled() == true then
         local roughLandPos = self.EyePos + Vector(self.laserLength,0):RadRotate(self):GetAimAngle(true);
         for i = 0, self.laserDensity do
            local checkPos = self.EyePos + Vector(self.laserSpaceCheck*i,0):GetAimAngle(true);
            if SceneMan.SceneWrapsX == true then
               if checkPos.X > SceneMan.SceneWidth then
                  checkPos = Vector(checkPos.X - SceneMan.SceneWidth,checkPos.Y);
               elseif checkPos.X < 0 then
                  checkPos = Vector(SceneMan.SceneWidth + checkPos.X,checkPos.Y);
               end
            end
            local terrCheck = SceneMan:GetTerrMatter(checkPos.X,checkPos.Y);
            if terrCheck == 0 then
               local moCheck = SceneMan:GetMOIDPixel(checkPos.X,checkPos.Y);
               if moCheck ~= rte.NoMOID and MovableMan:GetMOFromID(moCheck).Team ~= self.Team then
                  roughLandPos = checkPos;
                  break;
               end
            else
               roughLandPos = checkPos;
               break;
            end
         end
         local checkRoughLandPos = roughLandPos + Vector(self.laserSpaceCheck*-1,0):RadRotate(self):GetAimAngle(true);
         for i = 0, self.laserSpaceCheck do
            local checkPos = checkRoughLandPos + Vector(i,0):GetAimAngle(true);
            if SceneMan.SceneWrapsX == true then
               if checkPos.X > SceneMan.SceneWidth then
                  checkPos = Vector(checkPos.X - SceneMan.SceneWidth,checkPos.Y);
               elseif checkPos.X < 0 then
                  checkPos = Vector(SceneMan.SceneWidth + checkPos.X,checkPos.Y);
               end
            end
            local terrCheck = SceneMan:GetTerrMatter(checkPos.X,checkPos.Y);
            if terrCheck == 0 then
               local moCheck = SceneMan:GetMOIDPixel(checkPos.X,checkPos.Y);
               if moCheck ~= 255 then
                  break;
               end
            else
               break;
            end
            roughLandPos = checkPos;
         end
         local laserPar = CreateMOPixel("Nanorifle Laser Sight Glow");
         laserPar.Pos = roughLandPos;
         MovableMan:AddParticle(laserPar);
      end
   end
end
function UpdateAI(self)
   self.AI:Update(self)
end


Does not work. In the console error:
ERROR: no overload of 'Vector: RadRotate' matched the arguments (Vector, AHuman)
candidates are:
Vector: RadRotate (custom [float])

Is nothing said for me.

Hi there.

Look carefully at lines 14 and 36. Looks like you misplaced a parenthesis, instead of putting a ')' after last self, put it right at the end of the line before ';'. Otherwise you're trying to pass self (a reference to the actor and unexpected argument type) to the function RadRotate and then calling GetAimAngle on the return value.
