VirtualKeyBinding control,scanCode[,modifier]
Parameters
| control: key-button handle. scanCode: recognized Blitz scan code. modifier: Shift, Control, Alt or 0 (default). |
Description
Cancels the old contact before rebinding. Invalid bindings leave the button unchanged and set MobileInputError$. Labels are independent of bindings. A held finger must lift before pressing the rebound button.
Native overlays are supported on iOS, Android, macOS and Windows, including IDE run presets and saved layouts, and on the web, where the page draws them over the canvas. Controls use presentation coordinates, remain responsive during blocking input waits, and are excluded from SaveBuffer. See the mobile input guide. |
; VirtualKeyBinding Example
; Virtual keyboard: movement and action use only existing keyboard commands.
