"The import org.lwjgl.Display cannot be resol

OpenGL Development

Hi there!

As suggested by Middy I have downloaded Eclipse.

This code example, that demonstrates how to sett up an OpenGL Window, produces the below listed errors. As described in the above linked thread I have installed the LWJGL files as told to on the official site.

java -cp lwjgl.jar;lwjgl_test.jar;lwjgl_util.jar; org.lwjgl.test.WindowCreationTest
and
java -cp lwjgl.jar;lwjgl_media.jar;lwjgl_test.jar;lwjgl_util.jar; org.lwjgl.examples.spaceinvaders.Game
both work. (1st creates an empty window | 2nd. starts a space invaders game).

Eclipse finds the following problems:


  Description                                            Resource           In Folder          Location

Lesson01 is some old code, based on something prior to 0.93.

You can find up-to-date demos and tutorials here.

Thank’s. I’ll give them a try.

#5

if i remember correctly, in lwjgl 0.93 it is now called

import org.lwjgl.opengl.Display;

*note the addition of the .opengl bit

also note org.lwjgl.Window has been merged with Display so just replace where it says Window with Display.

I have updated the NeHe lessons, but have not had a chance to put them up on the WiKi. Until I put them up, you can get them all at http://members.rogers.com/mark.bernard/
