The speed of Ai and player becomes zero on punch
Hello! I was following a game tutorial on udemy but the course is deleted. The game consists of a platform with 4 Ai and 1 player where the player and Ai punches each other to fight and get their respective enemies out of the platform to gain score. My problem is, when the Ai punches another Ai or the main player, the speed of Ai or main player becomes zero and they don't move. Can anyone please help me with this?
Could you please upload some code to give us more information?

I do not know what is the problem. However, according to Unity documentation, it would be better not to modify Rigidbody.velocity directly. They recommend using AddForce.
