Vehicle Sample

[Stevemata]

The vehicle sample is broken in fork v4.0.30319

I have gone through and corrected the variable name changes, but I'm getting all sorts of other errors. Is there a fixed version?

[Norbo]

I'm not sure what fork you mean- as far as I'm aware, all the nondevelopment forks I manage should compile without errors.

Occasionally, the development version won't compile for the Xbox360 (usually due to my prototypes ignoring XBox360 Vector3 initialization details), but the very latest one I just put up there works. The latest development version can always be found here: http://bepuphysics.codeplex.com/SourceC ... evelopment

Edit:
v4.0.30319 refers to a .NET framework version. If you see errors related to that, some references probably got messed up somewhere.

[Stevemata]

My mistake, that's two for me today. I updated my references with the latest developer build and demos, it's working much better

I have the model drawer drawing the vehicles wheels, how do I get the modeldrawer to draw the vehicle's body?

[Norbo]

Add the vehicle's body entity to the ModelDrawer. In the BEPUphysicsDemos, there's a loop that runs after the demo is constructed which adds all entities in the Space.Entities list to the ModelDrawer; that's why there's no explicit add in the VehicleInput.

[Stevemata]

I added all of my entities to the model drawer, I'm still only getting the wheels. Is there some other setting to make sure the models are drawn?

[Norbo]

Make sure the ModelDrawer.Update and ModelDrawer.Draw methods are both called properly. It's possible for special case models like vehicle wheels to draw properly without a ModelDrawer.Update, but the entity representations won't.

[Stevemata]

Oh my, yeah no modeldrawer.update... that was it.

[Stevemata]

I'm attempting to replace the default wheel with a custom wheel, what world matrix transformation does the modeldrawer use to draw the wheels in the vehicle sample?

[Norbo]

The wheel shape exposes a world transform. From the VehicleInput update:

Code: Select all

            for (int k = 0; k < 4; k++)
            {
                WheelModels[k].WorldTransform = Vehicle.Wheels[k].Shape.WorldTransform;
            }

There will also likely be some local transform that is required to bring the wheel model into alignment with the wheel shape prior to applying the world transform.
