Hey there
I want to make a 2D platformer in space. But how can I make that a object is moving forever? If I push it a lil bit with a other object (example), it should move forever at the same speed.
I hope u can help me

Rigidbody has a drag property. It’s responsible for slowing down the object even when no other forces act on it. Set it to zero and your object should keep the velocity
@Casiell is right
Also, you could always create your own gravity and do rigidbody.addforce for spacelike Moment in zero gravity.
You could set the drag and use gravity of your rigidbody to 0 and false and change velocity of your rigidbody for spacelike movement.
Hope this helps @chernobyyl
