I have the code "
public void render() {
BufferStrategy bs = getBufferStrategy();
if (bs == null){
createBufferStrategy(3);
return;
}
Graphics g = bs.getDrawGraphics();
g.setColor(Color.black);
g.fillRect(0, 0, getWidth(), getHeight()) ;
g.dispose();
bs.show();
}
"
I do call it here "
public void run() {
while(running == true) {
tick();
render();
}
" What's going on with it? It's not displaying a black screen at all!

--- Update ---

I do have all of the things imported.
