[HELP] Ped looking at an object

[..:D&G:..]

Is there any easy way to have an action function that does something when the player looks straight at an object and presses 'E' for example, like in games like Rust or Reign Of Kings? Don't really know how to explain this, but here is an example:

Thanks.

So want a player pick up a object when press a key and look it?

[undefined]

As I understand as: SetPedLookAt

As I understand as: SetPedLookAt

Well I want to get the position of where the ped is looking at. Lets say I have a wood box on the ground, and if the player is close to it and is looking directly at the box, a message like "You are looking at the box" should appear.

function pedLooks(theElement) 
   local x, y, z = getElementPosition(localPlayer) 
   local bx, by, bz = getElementPosition(theElement) 
   local distance = getDistanceBetweenPoints3D(x, y, z, bx, by, bz) 
   if setPedLookAt(localPlayer, theElement)  and  distance <= 5 then 
      outputChatBox("You looking at "..theElement) 
   end 
end

hit, hitX, hitY, hitZ, hitElement = processLineOfSight ( float startX, float startY, float startZ,  
                                       float endX, float endY, float endZ,  
                                       [ bool checkBuildings = true,  
                                       bool checkVehicles = true,  
                                       bool checkPlayers = true,  
                                       bool checkObjects = true,  
                                       bool checkDummies = true,  
                                       bool seeThroughStuff = false,  
                                       bool ignoreSomeObjectsForCamera = false,  
                                       bool shootThroughStuff = false,  
                                       element ignoredElement = nil, 
                                       bool includeWorldModelInformation = false, 
                                       bool bIncludeCarTyres ] ) 
  

set ignoredElement to localPlayer and where its positions do

startX, startY, startZ, endX, endY, endZ = getCameraMatrix()

and then check if 'hit' is true and hitElement is the element which are u looking on.
