on race car game ERROR on ramp

[ufulio]

Hello, I just wanted to ask if anyone has any comments, to which I will be very grateful.
and it is that I have a ramp, in a game that I am making, and when I go at full speed the car stops suddenly.
but when I go slowly the car jumps perfectly.
…
I leave a photo of the colliders that the PREFAB car contains
and I leave a video where the car runs twice, one gets stuck, and the second time going slowly it jumps perfectly
…
I appreciate any comment.

here 20 seconds video :

Perhaps you are mis-using physics? Or you have some other collider glitch.

With Physics (or Physics2D), never manipulate the Transform directly. If you manipulate the Transform directly, you are bypassing the physics system and you can reasonably expect glitching and missed collisions and other physics mayhem.

This means you may not change transform.position, transform.rotation, you may not call transform.Translate(), transform.Rotate() or other such methods, and also transform.localScale is off limits. You also cannot set rigidbody.position or rigidbody.rotation directly. These ALL bypass physics.

Always use the .MovePosition() and .MoveRotation() methods on the Rigidbody (or Rigidbody2D) instance in order to move or rotate things. Doing this keeps the physics system informed about what is going on.

Collisions in high speed without unity physic / rigidbody

You say you’re not using 2D physics but you’re using queries therefore obviously colliders. This IS using 2D physics therefore you need to use it correctly so here are some basic rules: Don’t ever modify the Transform if using 2D physics components If you want a 2D Collider to move then add a Rigidbody2D and use its API to move it; many ways to do this. Rigidbody2D don’t make it “unresponsive”. If you want explicit control then set the body-type to Kinematic; it’s what it’s for. When…

OnCollisionEnter2D not being called

That’s not related to body-type. You should never drive via the Transform. The main thing to understand here is that the Rigidbody2D role is to write to the Transform after the physics simulation, not the other way around. It acts as a proxy to the Transform because you want physics behaviour. Does “it work” if you write to the Transform and force the Rigidbody2D to read from the Transform? Yes! It works like that because otherwise it’d be reported as a bug and so we’re forced to “support” it.…

With a wheel collider, use the motor or brake torque to effect motion.

If you want to try something other than the wheel colliders, here’s an approach I used that worked pretty neat:
