Hi!

Here is a bit of script that can show that OnKeyUp event not addressing every control key by its name. Instead of "SPACE" and "ENTER" I have to use ascii codes of these keys and change to Switch Asc(msg.key). What is the concept for such behaviour? I know that enter and space are displayable, so it has ascii codes, but IsKeyDown() can handle them by name. At least a bit of info in the guide would clarify the situation for newbies.

Code: Select all

Function p_key(msg)
    Switch msg.key
    Case "UP":
        Print("up")
        Case "DOWN":
            Print("down")
            Case "SPACE":
                Print("space")
                Case "ESC":
                    Print("esc")
                    Case "ENTER":
                        Print("enter")
                EndSwitch
            EndFunction

InstallEventHandler({Onkeyup=p_key})

Repeat
    WaitEvent
Forever

For SPACE you can use " " For ENTER you can use "/n"

Thanks Paul!

Tried it, but don't work, and not helps to make the script readable.

The following code works for me:

Code: Select all

Function p_key(msg)
Switch msg.key
Case "UP":
Print("up")
Case "DOWN":
Print("down")
Case " ":
Print("space")
Case "ESC":
Print("esc")
Case "\n":
Print("enter")
EndSwitch
EndFunction

InstallEventHandler({Onkeyup=p_key})

Repeat
WaitEvent
Forever

Hello rev

Ok. This is really works, however in your last post there was a simple slash for \n.

Thanks!

The idea behind the different behaviours of IsKeyDown() and the event handler is to make certain tasks easier. Supposed that you do something like

Code: Select all

InstallEventHandler({OnKeyUp = Function(msg) Print(msg.key) EndFunction})

If msg.key would contain "SPACE" now for every space press, it would be pretty annoying. Same for RETURN, ENTER etc. Well, but it all depends on the circumstances of course. In your case it's probably the other way round
