| Title: EnableDirectInput
| Code Submitted By:
- cloudnine
| | EnableDirectInput is a undocumented command that was introduced in V1.78 (or thereabouts). DirectInput is now disabled in all programs unless you use this command. Don't worry, you won't be affected, as Blitz now uses Windows messages (a.k.a the dreaded WndProc). The only reason I can see for using DirectInput is that it is slightly faster than Windows messages. |

Text(x,y,"text")
but its still good to know I think |
