Hey everyone,
I've just downloaded LWJGL 2.6 and right now I can't render anything!
I can't even make a call to any OpenGL method.
I've added the natives to the project in Eclipse and to the run-time variables.
A fullscreen display is made but does not close when receiving a NullPointer. And it receives the NullPointer at the first call to the render method.
Here is the code that I currently use:
package com.nitrocrime.games.lwjgl.test;
import org.lwjgl.LWJGLException;
import org.lwjgl.opengl.*;
import static org.lwjgl.opengl.GL11.*;
public class TestLauncher extends Thread
{
public static void main(String args[])
{
new TestLauncher();
}
private boolean rendering = true;
public TestLauncher()
{
try
{
DisplayMode mode = Display.getDisplayMode();
if (mode == null)
{
System.out.println("Error creating display mode");
return;
}
// configure and create the LWJGL display
Display.setTitle("LWJGL test");
Display.setDisplayMode(mode);
Display.setFullscreen(true);
Display.create();
this.start();
}
catch (LWJGLException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public void run()
{
while(rendering)
{
try
{
Thread.sleep(1000/60);
}
catch (InterruptedException e)
{
}
render();
}
}
private void render()
{
glClearColor(1.0f,0.0f,0.0f,1.0f);
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
}
}
And this is the error that I receive:
Exception in thread "Thread-0" java.lang.NullPointerException
at org.lwjgl.opengl.GL11.glClearColor(GL11.java:570)
at com.nitrocrime.games.lwjgl.test.TestLauncher.render(TestLauncher.java:65)
at com.nitrocrime.games.lwjgl.test.TestLauncher.run(TestLauncher.java:59)
Line 65 is the call to GLClearColor and line 59 is the call to render.
Have I made a mistake or is this maby a bug in LWJGL?
I am using a IMac 24 Inch with an NVidia geforce 9400 graphics card.
