Hooking

Create a hook

A hook is done using RegisterHook, the first argument is what you want to hook, and the second the name of the lua func you want the hook to run

Example:

function onDraw()
    -- This will run at draw, here you can use the draw funcs to draw primitives and text
end

function onFSN(frame)
    if frame == 3 then
        -- This will run in the NET_UPDATE_POSTDATAUPDATE_END frame in FrameStageNotify
    end
end

function onUI()
    UI.AddCheckbox("Test Checkbox", "test checkbox var")
end

RegisterHook("Draw", "onDraw")
RegisterHook("FrameStageNotify", "onFSN")
RegisterHook("UI", "onUI")
