Hi, i’m making a sport game, like a dodge ball game, i need help with the ball physics, how do i make it damage the player when it hits, depending on the impulse of the physics force?

RigidBody2D has a property called linear_velocity which returns a Vector of how fast your RigidBody2D object is moving.

Just use the Pythagorean formula if you want the c

var c =  sqrt((linear_velocity.x * linear_velocity.x) + (linear_velocity.y * linear_velocity.y))

use linear_velocity.length() is simpler.
