Hello,
I hope I m not too annoying with all my questions… :mrgreen:
I m going through the first tutorial (about Flag Rush) and I m stuck again…
The problem seems to come from the update method. I ve already written the rest.
@Override
protected void update(float interpolation) {
timer.update();
interpolation = timer.getTimePerFrame();
//if escape was pressed, we exit
if (KeyBindingManager.getKeyBindingManager().isValidCommand("exit")) {
finished = true;
}
}
When I execute the "game", I get the settings dialog, and then, a black screen (the game) and no sphere that directly shuts down. The console gives me a NullPointerException in the update method.
I think the problem comes from the timer, because if I put the first two lines in comments, I get a nice black screen with my textured sphere in the center.
I really dont know how to fix that...
Anyways here s the complete code:
