Collection was modified; enumeration operation may not...

I'm getting the following error:

Collection was modified; enumeration operation may not execute.

when trying to remove an entity from space on an initial collision event:

Code: Select all

        protected void Events_InitialCollisionDetected(EntityCollidable info, BroadPhaseEntry entry, INarrowPhasePair pair)
        {
            Kill();
        }

Code: Select all

        public override void Kill()
        {
            isValid = false;

            //entity.MotionState = MotionState.DefaultState;
            entity.LinearVelocity = new Vector3();
            entity.AngularVelocity = new Vector3();
            entity.WorldTransform = Matrix.Identity;

            game.Octree.RemoveObject(this);
            game.Space.Remove(entity);
        }

What is going wrong?

In the version you're using, removing entities from within an event handler is not allowed.

v0.15.2 (the latest released stable version) should allow it.

You're absolutely right, I hadn't updated to the latest version for this project.

Thanks for the help
