API:LCDButtonPressed
From RoR Wiki
UI Lua API · LCD functions
Version: WAR 1.4.8
Returns a value the client keeps for one of the four LCD soft buttons.
value = LCDButtonPressed(button)
Arguments
- button
number– Button number, 1 to 4.
Returns
- value
number– The value stored for that button in the client's LCD button data. What the value counts is not documented here.
Details
- A button number outside 1–4 logs the error below and returns nothing.
- To react to button presses, register a handler with LCDSetButtonHandler instead. The stock UI does that and never calls this function.
Errors

The number shown is one less than the number passed.
