How the button flags work

The instructionalKey / flags argument of SetWarningMessage andSetWarningMessageWithHeader is a bit field. Each bit adds one instructional button to the bottom of the alert screen. Add the values of the buttons you want: Yes (4) + No (32) =36.

SetWarningMessageWithHeader(titleMsg, entryLine1, flags, promptMsg, p4, p5, background, p7, showBg)

Things to know

  • The warning must be drawn every frame, so call it inside a loop with Wait(0).
  • It only accepts text entries, not raw strings. Register your own with AddTextEntry("MY_KEY", "text"), like the generated snippet does.
  • The buttons are only visual. You still have to check the keys yourself. Normal controls are blocked while the warning is up, but frontend controls in input group 2 still work: 201 accept (Enter),202 cancel (Esc), 203 alternative (Space).
  • Several bits share the same key, for example Select, OK, Yes and Continue are all Enter. The preview shows what the player sees, the snippet groups them into accept / cancel / alt.
  • The constant names in this tool (YES, CANCEL_TRANSFER…) are descriptive, the game has no official names for most bits.
