NPE when clearing points with bodies in world #29
Description
Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException
at com.badlogic.gdx.physics.box2d.World.destroyBody(World.java:309)
at aurelienribon.bodyeditor.canvas.rigidbodies.RigidBodiesScreen.clearWorld(Unknown Source)
at aurelienribon.bodyeditor.canvas.rigidbodies.RigidBodiesScreen.access$300(Unknown Source)
In RigidBodiesStream:
Iterator<Body> bodies = world.getBodies();
while (bodies.hasNext()) world.destroyBody(bodies.next());
This look suspicious; are you sure the iterator's backing collection isn't
modified?
A conservative approach:
boolean empty = false;
while (!empty) {
Iterator<Body> bodies = world.getBodies();
empty = !bodies.hasNext();
if (!empty) {
world.destroyBody(bodies.next());
}
}
