UiProcess and InputProcess events

[Apeirogon]

This two event on wiki page warn me that if I return true with one of this event, player will be locked from moving, event with lower order stop processing, all be bad.

But there are a way to bypass this using network event. And in this point I lost thread of thought. I must override two events one of which send all input and ui events in network? Write input event inside network event? Write network event inside input?

UiProcess and InputProcess are events to get direct access to keyboard events. Normally you don't have to return true in the events; also with InputProcess the game and the player just keeps moving. UIProcess is more meant for a kind of modal screens, at least that is where I use it for. In UIProcess you can also catch system keys like ESC and PrtScr and such, and provides also direct access to mouseX/Y coordinates and left/right/wheel button clicks.

Both events are UI bound, so you can't modify game data there; that's why the NetworkProcess event exists; when you use SendNetworkEvent in InputProcess or UiProcess, you can receive and process the information in NetworkProcess.

Very simple example for Input:

Code: Select all

	override bool InputProcess (InputEvent e)
	{
		if (e.Type == InputEvent.Type_KeyDown && automapactive == false) // not when automap is active
			SendNetworkEvent("keypress", e.KeyScan);
			
		return false;
	}


	override void NetworkProcess(ConsoleEvent e)
	{	
		if (e.Name == "keypress")	
		       console.printf("%d", e.Args[0]);
	}

Ooooo, send RESULT of event.
I think about sending ENTIRE event...

Also, how check buttons in input process? I mean, what name I must use for key, say "L"?

See the console.printf in my example for the exact value; otherwise see in gzdoom.pk3 the events.txt , struct InputEvent.

Btw, in my example I used e.KeyScan which is an internal code for the engine, but you can also use the ascii code, which is represented by e.KeyChar.

Okay, now I know what button player press, release and how long it was pressed.

How check is this button do something inside game? Like, I want check how much time player press "use" button.

Like, I want check how much time player press "use" button.

Using the same keypress command as in the previous example, it would be something like this:

Code: Select all

int used;  //<== local variable in your eventhandler class

override void OnRegister()
{
    used=0;
}

override bool InputProcess (InputEvent e)
{
      if (e.Type == InputEvent.Type_KeyDown && automapactive == false) // not when automap is active
         SendNetworkEvent("keypress", e.KeyScan);
         
      return false;
}

override void NetworkProcess(ConsoleEvent e)
{         
      
      if (e.Name == "keypress")
      {
         int key1, key2;
         [key1, key2] = Bindings.GetKeysForCommand("+use");
         if ((key1 && key1 == e.Args[0]) || (key2 && key2 == e.Args[0]))
         {
            used++;
         }
      }
}

Why you check two time value of argument from input event? This important?

Why you check two time value of argument from input event? This important?

You mean this: if ((key1 && key1 == e.Args[0]).. ?

[Apeirogon]

More specific, why

Code: Select all

         [key1, key2] = Bindings.GetKeysForCommand("+use");
         if ((key1 && key1 == e.Args[0]) || (key2 && key2 == e.Args[0]))

instead

Code: Select all

         key = Bindings.GetKeysForCommand("+use");
         if (key && key == e.Args[0])

[gwHero]

Because Bindings.GetKeysForCommand returns 2 values; you can have 2 keys assigned to an action.
