No that is incorrect. That warning is from another line. Line 1 is correct.

[DarkByte]

Still not working

[IIYAMA]

Amazing, that you say it doesn't work, when you haven't even make the line thicker. And if you did, show us that code and a screenshot of it.

[DarkByte]

And how to make it thicker?

function renderTankLine() 
    local theVeh = getPedOccupiedVehicle(localPlayer) 
    if theVeh and getElementModel(theVeh) == 432 then 
        local x,y,z = getVehicleComponentPosition( theVeh, "misc_c" ) 
        local x1,y1,z1 = getVehicleComponentPosition( theVeh, "misc_a" ) 
        if x and x1 then 
            local endX,endY,endZ = extendLine(x,y,z,x1,y1,z1,300) 
            dxDrawLine3D (x,y,z,endX,endY,endZ,tocolor(255,0,0,255)) 
        end 
    end 
end 
addEventHandler("onClientRender",root,renderTankLine) 
  
  
 function extendLine ( x,y,z,x2,y2,z2,length ) 
        local vx = x2 - x 
        local vy = y2 - y 
        local vz = z2 - z 
        local ratio = length/(getDistanceBetweenPoints3D ( x,y,z,x2,y2,z2 )) 
        vx = vx*ratio 
        vy = vy*ratio 
        vz = vz*ratio 
        return (x + vx),(y + vy),(z + vz) 
    end 

[IIYAMA]

dxDrawLine3D ( float startX, float startY, float startZ, float endX, float endY, float endZ, int color[, int width, bool postGUI ] ) 

dxDrawLine3D (x,y,z,endX,endY,endZ,tocolor(255,0,0,255)[color=#FF0000],10[/color]) 

dxDrawLine3D (x,y,z,endX,endY,endZ,tocolor(255,0,0,255),10) 

[DarkByte]

Not working.

function renderTankLine() 
    local theVeh = getPedOccupiedVehicle(localPlayer) 
    if theVeh and getElementModel(theVeh) == 432 then 
        local x,y,z = getVehicleComponentPosition( theVeh, "misc_c" ) 
        local x1,y1,z1 = getVehicleComponentPosition( theVeh, "misc_a" ) 
        if x and x1 then 
            local endX,endY,endZ = extendLine(x,y,z,x1,y1,z1,300) 
            dxDrawLine3D (x,y,z,endX,endY,endZ,tocolor(255,0,0,255),10) 
        end 
    end 
end 
addEventHandler("onClientRender",root,renderTankLine) 
  
  
 function extendLine ( x,y,z,x2,y2,z2,length ) 
        local vx = x2 - x 
        local vy = y2 - y 
        local vz = z2 - z 
        local ratio = length/(getDistanceBetweenPoints3D ( x,y,z,x2,y2,z2 )) 
        vx = vx*ratio 
        vy = vy*ratio 
        vz = vz*ratio 
        return (x + vx),(y + vy),(z + vz) 
    end 

[IIYAMA]

Now I tested it my self.

local extendLine = function ( x,y,z,x2,y2,z2,length ) 
    local vx = x2 - x 
    local vy = y2 - y 
    local vz = z2 - z 
    local ratio = length/(getDistanceBetweenPoints3D ( x,y,z,x2,y2,z2 )) 
    vx = vx*ratio 
    vy = vy*ratio 
    vz = vz*ratio 
    return (x + vx),(y + vy),(z + vz) 
end 
local renderTankLine = function () 
    local theVeh = getPedOccupiedVehicle(localPlayer) 
    if theVeh and getElementModel(theVeh) == 432 then 
        local x,y,z = getVehicleComponentPosition( theVeh, "misc_c","world" ) -- < problem 
        local x1,y1,z1 = getVehicleComponentPosition( theVeh, "misc_a","world" ) -- < problem 
        if x and x1 then 
            local endX,endY,endZ = extendLine(x1,y1,z1,x,y,z,10000) 
            dxDrawLine3D (x,y,z,endX,endY,endZ,tocolor(255,0,0,255),10) 
        end 
    end 
end 
addEventHandler("onClientRender",root,renderTankLine) 

And solved the problem...

[DarkByte]

Thanks man you're the best!

[DarkByte]

One more thing. Line is going through walls.

[IIYAMA]

Try this:

local extendLine = function ( x,y,z,x2,y2,z2,length ) 
    local vx = x2 - x 
    local vy = y2 - y 
    local vz = z2 - z 
    local ratio = length/(getDistanceBetweenPoints3D ( x,y,z,x2,y2,z2 )) 
    vx = vx*ratio 
    vy = vy*ratio 
    vz = vz*ratio 
    return (x + vx),(y + vy),(z + vz) 
end 
local renderTankLine = function () 
    local theVeh = getPedOccupiedVehicle(localPlayer) 
    if theVeh and getElementModel(theVeh) == 432 then 
        local x,y,z = getVehicleComponentPosition( theVeh, "misc_c","world" ) 
        local x1,y1,z1 = getVehicleComponentPosition( theVeh, "misc_a","world" ) 
        if x and x1 then 
            local  = extendLine(x1,y1,z1,x,y,z,10000) 
            local hit,endX2,endY2,endZ2 = processLineOfSight ( x,y,z,endX,endY,endZ

            if hit then 
                endX,endY,endZ = endX2,endY2,endZ2 
            end 
             
            dxDrawLine3D (x,y,z,endX,endY,endZ,tocolor(255,0,0,255),10) 
        end 
    end 
end

Thanks man. It had some errors in syntax but i already fixed.

[DarkByte]

But can you help add a image as crosshair at tank?

[IIYAMA]

Try this, edit the variables on the top.

    vx = vx*ratio 
    vy = vy*ratio 
    vz = vz*ratio 
    return (x + vx),(y + vy),(z + vz) 
end 
local texture = createTexture(imageLocation,"dxt5") or imageLocation -- createTexture + fallback

Not working. It sais failed to create texture in debug
