Simulating keyboard and mouse input

[somewhatOfACoder]

I am trying to simulate keyboard and mouse input for a neural network but I can't figure out how to actually get the keys to be pressed. I put the following code into a separate class but when I call the jump method nothing happens.

public static void jump() {
  Minecraft mc = Minecraft.getInstance();
  KeyBinding.setKeyBindState(mc.gameSettings.keyBindJump.getKey(), true);
  KeyBinding.onTick(mc.gameSettings.keyBindJump.getKey());
}

The method is indeed being called but the jump keybind isn't changing whatsoever.

How do I go about simulating these inputs?

Looking at both KeyboardListener#setupCallbacks and MouseHelper#registerCallbacks, I can see that I need to use the following:

// for the keyboard
this.onKeyEvent(windowPointer, key, scanCode, action, modifiers);

// for the mouse
this.mouseButtonCallback(handle1, button, action, modifiers);

However I am unsure as to how to get the windowPointer and the handle1. From what I understand, InputMappings#setKeyCallbacks gives the necessary parameters, but calling this again would mean that I would need my own onKeyEvent and mouseButtonCallback methods to handle the input.

Do I need to call InputMappings#setKeyCallbacks again or is there a nice way to get the windowPointer and the other parameters?

Ok so I changed the method I made to be the following:

public static void jump() {
		Minecraft mc = Minecraft.getInstance();
		int jumpKeyCode = mc.gameSettings.keyBindJump.getKey().getKeyCode();
		int scanCode = jumpKeyCode;
		int action = 1;
		int modifiers = 0;
		mc.keyboardListener.onKeyEvent(mc.getMainWindow().getHandle(), jumpKeyCode, scanCode, action, modifiers);
	}

However it still doesn't work. The keyCode is fine, but I am not sure about how to get the scanCode. I had a look at KeyboardListener#onKeyEvent and it seems that if the action is 1 then the key will be pressed. I am also not sure about the modifiers because I can't find where it is used.

Ok I am now stumped. I read the input guide and made a callback method for the keyboard which allowed me to get the keycode, scancode, action and modifier of whatever key I typed. However after using these values as parameters for KeyboardListener#onKeyEvent, nothing happened. For example, the space bar has a keycode of 32, a scancode of 57, an action of 1 when pressed and no modifiers. When I put these values directly into KeyboardListener#onKeyEvent nothing happened. Help?

Unforntunately I haven't got it to work. I tried sending two presses as you said, one down then one up, but it didn't work. Do I need to have some sort of delay inbetween? And if so how do I do that
