VKeyDown:Int32 scancode:Int32

Parameter	Mode	Type	Default	Description
scancode	In	Int32	required	The SDL scancode of the key, 1 to 511.

Returns: 1 while the key is held down, otherwise 0.

Description

Tells whether a key is held down right now, asking for the key by its SDL scancode instead of the DirectInput code that KeyDown takes. Every key has an SDL scancode (F16 is 107, Pause is 72, the left Windows key is 227), so this reaches the keys that KeyDown cannot. The codes are the same on every platform and do not change with the keyboard layout. See Scan Codes for the table.

Differences

• This is a BlitzLLVM extension: the original has no such command.
