Any way to check if any key was pressed?

There are some way to check if any key, "a", F1", "Ctrl" or "Alt" etc.. keys are pressed and know the KEYs VALUEs of it?

If KeyHit(KEY_A) Then 'Do something!
If KeyHit(KEY_F1) Then 'Do something!
If KeyHit(MODIFIER_CONTROL) Then 'Do something!
If KeyHit(MODIFIER_ALT) Then 'Do something!

etc..

If you go to the documentation for KeyDown() or KeyHit() there should be a link to 'key codes' (a list of valid key codes).

While True
	For key:Int = 1 To 183
		If KeyDown(key) Then
			Print key
			End
		EndIf
	Next
Wend

Yes I know that.

But I want to check on my main loop if anykey are pressed to execute some function asociated with some behavior of my sprite and pass the value of keys to the function.

Checking every key state every time through a loop is very inefficient.

So you want to check for specific keys, not any key?

In the main loop want to check for any key then pass the getted key_coded to each sprite behavior and inside of behavior scheck what is the key to make the action.

So you want to check for any key to be pressed then send it off to a function, fair enough. What does that function do?

AddHook EmitEventHook,KeyHook,Null,0

Function KeyHook:Object( id,data:Object,context:Object )

	Local event:TEvent=TEvent(data)
	Select event.id
		Case EVENT_KEYDOWN
			Print event.data
	End Select
	Return data

End Function


While Not KeyDown(KEY_ESCAPE)
	Cls
	Flip
Wend
End

Swap the Print event.data for a Select..Case with the keycodes you want to check.

Thanks Perturbatio for that, work great.
