Warning Screen Buttons

Warning Screen Buttons calculates the button flags for the full-screen GTA V alert (the black “Alert” screen with Yes / No at the bottom). You pick the buttons, see a preview with your own text, and copy a Lua snippet that draws the screen and waits for the player’s choice.

What it is for

SetWarningMessage and SetWarningMessageWithHeader take a bit field that decides which instructional buttons appear on the screen. Each bit adds one button: Yes is 4, No is 32, so Yes / No is 36. Useful for “are you sure” prompts: leaving a job, deleting a character, confirming a purchase.

Quick start

1. Pick a Preset (the page opens on Yes / No, 36) or toggle buttons.
2. Fill Header, Line 1 and Line 2 in the Text panel and check the Preview.
3. Turn Black background on or off.
4. Copy warning.lua.

Decode a value in the Button flags panel reads 36, 0x24 or 4 | 32 and shows which buttons it contains.

Button flags

The constant names are descriptive labels used by this tool. The game has no official names for most of these bits.

The generated snippet

The snippet registers your text with AddTextEntry (warning screens only take text entry keys, not raw strings), then draws the screen every frame until a key is pressed. Buttons are grouped by what they mean, and each group is checked with frontend controls in input group 2, which still work while the warning is up:

For Yes / No it looks like this:

local WARNING_FLAGS = 36 -- YES | NO

AddTextEntry("FM_WARN_HEADER", "Alert")
AddTextEntry("FM_WARN_LINE1", "Are you sure you want to leave the server?")
AddTextEntry("FM_WARN_LINE2", "Unsaved progress will be lost.")

local function ShowWarning()
    while true do
        SetWarningMessageWithHeader("FM_WARN_HEADER", "FM_WARN_LINE1", WARNING_FLAGS, "FM_WARN_LINE2", false, -1, true, 0, true)
        if IsControlJustPressed(2, 201) or IsControlJustPressed(2, 217) then return "accept" end
        if IsControlJustPressed(2, 202) then return "cancel" end
        Wait(0)
    end
end

CreateThread(function()
    local choice = ShowWarning()
    if choice == "accept" then
        print("Accepted")
    elseif choice == "cancel" then
        print("Cancelled")
    end
end)

If only the loading spinner (or nothing) is selected, there is nothing to press, so the snippet shows the screen for 5 seconds instead.

Tips

• The warning has to be drawn every frame, inside a loop with Wait(0).
• Several bits share a key. Select, OK, Yes and Continue are all Enter, so combining two of them gives the player two labels for the same key.
• Black background is passed as the background argument of SetWarningMessageWithHeader.

Limitations

The preview is an approximation of the game’s layout, not a screenshot. Everything runs in the browser.
