I should note that ray casts will be slightly faster than convex casts and there usually is no perceptible difference in behavior between the two. I would recommend sticking with ray cast wheels just for ease of use if possible. I cannot use raycast wheel, because the presence of the slot. which ca...

mmm I'm trying to use a convex cast.. I did what you wrote, creating a new class by copy/paste of the RayCastWheelShape. then I used collidable.ConvexCast(_shape, ref startingTransform, ref sweep, out hit) instead of the collidable.RayCast(new Ray(base.wheel.Suspension.WorldAttachmentPoint, base.whe...

I saw that on a previous version of the BEPU, there was a ConvexCastRayWheel. why have you removed it from the engine? From a performance point of view, it would be better to use a raycasted wheel, or a constraint/entity wheel (like a cylinder)? (ex. is better a vehicleinput approach or a cuspension...

Maybe I found the issue.... for better joint stability, during some previous test I added a static capsule under the paddle. So that the paddle rotate around Y axis, and at the same origin, there's a static capsule (with a radius < of the minimum radius of the paddle) joined to the car's box to form...

Some more informations: - I've enabled PositionUpdateMode.Continuous for the Paddle. - With the paddle as squished cylinder, the Narrow Phase goes from 0.6 to 7-8ms but with some spikes to 15ms in certain circumstances. This is an example of a turn, so you may see the density of the tasselation (I d...

Using a squished cylinder works a lot better. But not enough. Which are the params which affect the Narrow phase, for tuning? Reducing the size of the AABB area, should consume more memory but also should reduce the number of triangles to test. Or not? I know the size of the paddle, so that it isn't...

The slowdown spikes, and it coincide with collisions in areas of the mesh with denser tessellation (when the car perform a turn). The paddle is a cylinder mesh, with an ellipsoide as base (instead of circle): Note: I forgot to simplify its physic model. http://www.magicstudio.eu/tmp/paddle.png Some ...

Ok, I edited the topic subject, so that I'll use this topic for all my questions :) Actually, I've a fully functional slot car game. Every track part is a mesh, with the paddle which is inserted into the slot and pull the car around the track. Even with bigger tracks I haven't any framedrops. From t...

I have a problem with the join of two meshes. Each mesh is a model of a track part of the slot car game. so each model the "front" and the "back" of the model has the same vertices, so that they can be attacched each other. Simple Example: I have two model (two boxes), BoxA and B...

For the game on that video, I may confirm that he use the paddle on the slot approach. About my issue, I found the problem :) The wheels doesn't have enough traction when the paddle collide with the slot. So the wheel skids, instead of get traction and continue to pull the car. I solved, removing th...

I'll check and try tomorrow. Thanks for the support.

p.s.
Have a look at this: http://www.kjow.net/
He use a full physic engine to move the car. As I would like to reproduce.
he use Newton Physic Engine

I will look at the demo, but if I would like to try this route also? is There a way to preserve the velocity after a collision? Even at slow speed and with high curve tassellation, the speed of the car slow down. Other info: The paddle is a capsule with a radius smaller than the width of the slot. T...

Hi, I'have a problem. I'm writing a Slot Card game. I'have a car, with a paddle below it. When tha car moves, the paddles moves inside the slot. what I would like to have, is that the paddle shouldn't brake the car while colliding with the slot. (but should response to a collision, to allow the car ...

actually I'm tesing with bepu demo project. I added a new screen demo.

I'm doing more tests.. later I'll add more infos.

tryed. same effect. boxB rotate around his joint point with the boxA
