Use Keyboard

[bbjam]

I'm trying to use the Keyboard class insted of Java's key events for my game engine, but when I try to .create() the keyboard I get

Exception in thread "main" java.lang.IllegalStateException: Display must be created.
	at org.lwjgl.input.Keyboard.create(Keyboard.java:319)
	at com.glassFlame.event.EventSystem.<init>(EventSystem.java:43)
	at com.glassFlame.scene.SceneBuilder.createScene(SceneBuilder.java:19)

Yes, you can't use the keyboard without some kind of display.

See Display.create()

By that I think you mean org.lwjgl.opengl.Display.

Big thanks

b.t.w. Is there any way to draw on the surface you get from Display.create() with Java2D?

I just made my very first OpenGL window, and keypresses seem to work without me having to call "Keyboard.create()" ... is this just a matter of style, or is it actually important?

I'm just using Keyboard.isKeyPressed() calls, by the way.

input creation is now done automatically when you create the display.

[Buggy]

So does calling Keyboard.create() create a second keyboard object? Or is calling it just good coding style, and no new object is created?

[Matzon]

If the keyboard hasn't been created, it wil create it - otherwise it will just do nothing.

[Buggy]

Except, if I understand correctly, the keyboard can't be created without first creating a display. And creating a display automatically creates a keyboard, rendering Keyboard.create() completely useless.

Is there something I'm missing here?

[Matzon]

a) its old code, hence no need to break stuff
b) you can disable automatic input creation using:
org.lwjgl.opengl.Display.nokeyboard
org.lwjgl.opengl.Display.nomouse
org.lwjgl.opengl.Display.noinput

Ah... thanks for clearing that up.
