In my main class:
/* next step for physics events */
toDestroy = new Vector<Body>();
w.step(BOX_STEP, BOX_VELOCITY_ITERATIONS, BOX_POSITION_ITERATIONS);
//System.out.println(theBall.getPos()+" | "+Math.abs(Math.toDegrees(theBall.getRotation()))%360);
/* destroy objects for destruction (e.g. - experience gems that have been picked up, bullets that have collided with another object) */
for (int i=0;i<toDestroy.size();i++){
Body b = toDestroy.elementAt(i);
b.setAwake(false);
w.destroyBody(b);
}
In my class that contains the physics world, its objects and the collision listener:
private void createCollisionListener() {
ContactListener cl = new ContactListener() {
@Override
public void beginContact(Contact contact) {
Fixture fixtureA = contact.getFixtureA();
Fixture fixtureB = contact.getFixtureB();
LogapBall lball = cast(fixtureA.getBody().getUserData(), fixtureB.getBody().getUserData(), LogapBall.class);
LogapExpGem leg = cast(fixtureA.getBody().getUserData(), fixtureB.getBody().getUserData(), LogapExpGem.class);
LogapBox lbox = cast(fixtureA.getBody().getUserData(), fixtureB.getBody().getUserData(), LogapBox.class);
LogapBullet lbull = cast(fixtureA.getBody().getUserData(), fixtureB.getBody().getUserData(), LogapBullet.class);
if(lbull !=null && lball == null){
ItLoGaP.toDestroy.addElement(lbull.getBody());
}
I read somewhere that a usual cause of the app crashing when trying to destroy box2d objects is when you’re trying to destroy the object inside the world step. This is why I just created a Vector in the main class, which is populated with bodies to destroy while the world step is ongoing so that once the step finishes, that’s the only time when the bodies will actually be destroyed.
So now that my game is still crashing… I have no idea what’s still causing it.
