* The button indices are shown in the GECK when editing the message object and remain the same even if certain buttons are hidden with conditions.

* As demonstrated in the example above, always store the return value of GetButtonPressed in a variable, then check the variable instead of calling GetButtonPressed directly in an "if" statement. Attempting to call GetButtonPressed in successive "if" conditions will cause your menu to fail silently for all options except the first—the first "if" statement calls GetButtonPressed and gets the value of the button pressed, clearing the stored information. GetButtonPressed will then return -1 for each of the remaining "if" statements. | |||
