processLineOfSight problem

[Kenix]

I have a problem when the bot behind the wall we see image please help fix it.

  
addEventHandler( "onClientRender", getRootElement(), 
   function( ) 
    for _, plr in ipairs( getElementsByType( "ped" ) ) do 
        if (getElementData (plr, "zombie") == true and getElementData(plr, "status" ) ~= "dead")  then 
            local Px,Py,Pz = getElementPosition( getLocalPlayer() ) 
            local Zx,Zy,Zz = getElementPosition( plr ) 
            local distance = (getDistanceBetweenPoints3D (Px, Py, Pz, Zx, Zy, Zz)) 
            if (distance < 35) and (distance > 2) then    
                local x, y, z = getPedBonePosition( plr, 8 ) 
                local sX, sY,sZ = getScreenFromWorldPosition( x, y, z+0.5 ) 
                local cx, cy, cz = getCameraMatrix() 
                local ht,hX,hY,hZ,hE  = processLineOfSight(cx, cy, cz,sX, sY,sZ,true,false, false, true, false, false,false,false,plr) 
                if ht then 
                    if sX then 
                        if getElementData( plr ,"zClass") == 6 then  
                            dxDrawImage(sX, sY,10, 10,"w.png") 
                    elseif getElementData( plr ,"zClass") == 1 then  
                            dxDrawImage(sX, sY,10, 10,"wg.png") 
                    elseif getElementData( plr ,"zClass") == 2 then 
                            dxDrawImage(sX, sY,10, 10,"g.png") 
                    elseif getElementData( plr ,"zClass") == 3 then 
                            dxDrawImage(sX, sY,10, 10,"y.png") 
                    elseif getElementData( plr ,"zClass") == 4 then 
                            dxDrawImage(sX, sY,10, 10,"r.png")  
                    elseif getElementData( plr ,"zClass") == 5 then 
                            dxDrawImage(sX, sY,10, 10,"b.png") 
                            end 
                        end 
                   end 
              end 
          end 
      end 
   end

you don't need to use getScreenFromWorldPosition( x, y, z+0.5 ) for line of sight, just do processLineOfSight(cx,cy,cz,x,y,z+0.5)

thx karlis.

So I removed the image that was visible through objects, etc. but now there is no image at all please help

  
addEventHandler( "onClientRender", getRootElement(), 
   function( ) 
    for _, plr in ipairs( getElementsByType( "ped" ) ) do 
        if (getElementData (plr, "zombie") == true and getElementData(plr, "status" ) ~= "dead")  then 
            local Px,Py,Pz = getElementPosition( getLocalPlayer() ) 
            local Zx,Zy,Zz = getElementPosition( plr ) 
            local distance = (getDistanceBetweenPoints3D (Px, Py, Pz, Zx, Zy, Zz)) 
            if (distance < 35) and (distance > 2) then    
                local x, y, z = getPedBonePosition( plr, 8 ) 
                local sX, sY,sZ = getScreenFromWorldPosition( x, y, z ) 
                local cx, cy, cz = getCameraMatrix() 
                local ht,hX,hY,hZ,hE  = processLineOfSight(cx, cy, cz,x, y,z + 0.5,false,false,false,false,false,false,false,false,plr)  
                if ht then 
                    if sX then 
                        if getElementData( plr ,"zClass") == 6 then  
                            dxDrawImage(sX, sY,10, 10,"w.png") 
                    elseif getElementData( plr ,"zClass") == 1 then  
                            dxDrawImage(sX, sY,10, 10,"wg.png") 
                    elseif getElementData( plr ,"zClass") == 2 then

                            dxDrawImage(sX, sY,10, 10,"b.png") 
                            end

you need to see image when zombie is behind wall or when it is not?

if when not you need to put "if not hit then "
