Space Game test

This is my second project and the first posted on the website.
I have a problem with this, I am using a scrolling world which I got from a demo scenario, which works fine with my own stuff put in, but I am trying to put a smoke effect in, to leave a trail behind the ship, but I think because the smoke is made as a child of the ship, which is staionary to the camera, the smoke is also stationary. Also is it possible to only produce smoke if your moving? I presume you'd do that by checking if UP is held, then doing makeSmoke.

Thanks

The Smoke class should extend the ScrollActor class. That, and you using the wrong x and y to place your smoke into the world (in the ship class). The 'makeSmoke' method should be like this: private void makeSmoke() { count--; if (count == 0) { ScrollWorld sw = (ScrollWorld) getWorld(); getWorld().addObject ( new Smoke(), sw.getCameraX(), sw.getCameraY()); count = 2; } } You may want to add a 'setPaintOrder' statement in your subclass of ScrollWorld. Oh, and move your call to 'makeSmoke' inside the 'up' key detection clause

Ok, this makes the smoke no longer attached to the ship and it leaves a trail when up is pressed, BUT, the smoke also leaves the ship entirely, and appears to be keyboard controlled still. All that needs to happen is that the smoke is spawned in the world at a specific point, not relative to the screen, and stays there until it disappears.

The 'specific point' being where it ship is at the time. Sorry that wasn't very clear.
