SceneContainer::getBinRange() - Bad Range

by JohnT · in Torque X 2D · 06/22/2008 (3:53 pm) · 3 replies

I am carrying this forward from the General Discussion area since I believe this to be a bug in the engine.

The problem is that I keep receiving an Assert while using the RigidComponent while also moving the object in code. The Assert appears to be originating from SceneContainer.cs at line 748

Assert.Fatal(max >= min, "SceneContainer::getBinRange() - Bad Range!");

Primarily the Assert happens when I am moving the object using the following to move in a forward direction and fire a weapon at it. When I step into the code after hitting Retry I get NaN for max and min.

obj.Scene.Position += new Vector3(obj.Scene.Transform.Forward.X*10, obj.Scene.Transform.Forward.Y*10, 0);


I should mention that I am running on a quad core processor and I am seeing all processors working so I am assuming that this could be a mult-threading issue.

I've gotten that error alot too.. when I got it I was just piling up objects and throwing grendades at them.

You might try using Velocity to move the object, then it might play better with the rigid physics, who knows.

Thanks, sounds like a good idea.
I'll give that a try and see if the Asserts come up less often.

Yeah, I pretty much pulled that advice right out of the source
/// <summary>
        /// The velocity of the object. This property should be used to move an object
        /// instead of the scene group's Position property so the object can resolve collisions
        /// properly. Movement will also be smoother. This value will be changing constantly as
        /// the object collides with other objects. To force it to stay the same, set Kinetic to
        /// true.
        /// </summary>
        public Vector3 Velocity
        {
            get { return _rigidBody.Velocity; }
            set { _rigidBody.Velocity = value; }
        }
