This function draws a 2D line across the screen - rendered for one frame. This should be used in conjunction with onClientRender in order to display continuously.

Syntax

 dxDrawLine ( )

Code Examples

Example 1 Example 2

client

This example draws an 'X' across the screen.

local screenWidth, screenHeight = guiGetScreenSize()
local lineColor = tocolor(255, 0, 0)
function drawLinesAcrossScreen()
  dxDrawLine(0, 0, screenWidth, screenHeight, lineColor)
  dxDrawLine(screenWidth, 0, 0, screenHeight, lineColor)
end
addEventHandler("onClientRender", root, drawLinesAcrossScreen)

client

This example draws a couple of circles

function drawCircle(x,y, radius, color)
    local numPoints = math.floor(math.pow(radius, 0.4) * 5)     -- Calculate number of points to make it look good
    local step = math.pi * 2 / numPoints
    local sx,sy
    for p=0,numPoints do
        local ex = math.cos(p * step) * radius
        local ey = math.sin(p * step) * radius
        if sx then
            dxDrawLine(x+sx, y+sy, x+ex, y+ey, color)
        end
        sx,sy = ex,ey
    end
end

addEventHandler("onClientRender", root, function()
    drawCircle(350, 350, 10, tocolor(255,0,255))
    drawCircle(350, 350, 50, tocolor(255,0,255))
end)
