Hi all,

This a code to make a laser for weapon but he not work,

pls fix it if have a problem and thx!

client-side:

addEventHandler( "onClientRender",  getRootElement(), 
    function() 
        local players = getElementsByType("player") 
        for k,v in ipairs(players) do 
                DrawLaser(v) 
             
        end 
    end 
) 
  
function DrawLaser(player) 
        local targetself = getPedTarget(player) 
        if targetself and targetself == player then 
            targetself = true 
        else 
            targetself = false 
        end      
         
        if  IsPlayerWeaponValidForLaser(player) == true and targetself == false then 
            local x,y,z = getPedWeaponMuzzlePosition(player) 
            if not x then 
                outputDebugString("getPedWeaponMuzzlePosition failed") 
                x,y,z = getPedTargetStart(player) 
            end 
            local x2,y2,z2 = getPedTargetEnd(player) 
            if not x2 then 
                --outputDebugString("getPedTargetEnd failed") 
                return 
            end          
            local x3,y3,z3 = getPedTargetCollision(player) 
            local r,g,b,a = GetLaserColor(player) 
            if x3 then -- collision detected, draw til collision and add a dot 
                dxDrawLine3D(x,y,z,x3,y3,z3, tocolor(r,g,b,a), laserWidth) 
                DrawLaserDot(player, x3,y3,z3) 
            else -- no collision, draw til end of weapons range 
                dxDrawLine3D(x,y,z,x2,y2,z2, tocolor(r,g,b,a), laserWidth) 
                DestroyLaserDot(player) 
            end 
        else 
            DestroyLaserDot(player) -- not aiming, remove dot, no laser 
        end 
  
end 
 function IsPlayerWeaponValidForLaser(player) -- returns false for unarmed and awkward weapons 
    local weapon = getPedWeapon(player) 
    if weapon and weapon > 21 and weapon < 39 and weapon ~= 35 and weapon ~= 36 then 
        return true 
    end 
    return false 
end 
  
  
function DrawLaserDot (player, x,y,z) 
    if not dots[player] then 
        dots[player] = createMarker(x,y,z, "corona", .05, GetLaserColor(player)) 
    else 
        setElementPosition(dots[player], x,y,z) 
    end 
end 
function DestroyLaserDot(player) 
    if dots[player] and isElement(dots[player]) then 
        destroyElement(dots[player]) 
        dots[player] = nil 
    end 
end
