Make an object fall at a fixed speed

Hi!, I have been thinking about how to do this but i didnt reach anywhere. Basicaly i want objects to fall at a fixed speed, but them as well should being able to collide using the physics engine. Changing the transform of the object over time or its rigidbody2d.velocity is not an option because it makes the collisions looks awful.
If you know how can i solve it or you came up with something that could work let me know. Thanks!

 

Use a kinematic RigidBody and move it via script using MovePosition.

 

I assume you don't want it to slow down? You can always just use the gravity in the rigidbody's properties which will make it fall at terminal velocity depending to gravity and drag.

 

not working too ?
if (rigidbody.velocity.y < maxSpeed) rigidbody.velocity = new Vector2 (rigidbody.velocity.x, maxSpeed);

 

Thanks! now it is working fine.
