        dxUpdateScreenSource(screenSource)     
        dxSetShaderValue(blackWhiteShader, "screenSource", screenSource)
        dxDrawImage(0, 0, screenX, screenY, blackWhiteShader)
    end
end



local marker = createMarker(0, 0, 3, "cylinder", 2)

addEventHandler("onClientMarkerHit", marker, function()
    addEventHandler("onClientPreRender", getRootElement(), doBlackAndWhite)
end)

addEventHandler("onClientMarkerLeave", marker, function()
    removeEventHandler("onClientPreRender", getRootElement(), doBlackAndWhite)
end)
