Predict RigidBody2D movement if velocity(x,y) is applied

7892

I'm trying to predict where a RigidBody2D will fly if velocity(x,y) is applied and this is working fine if the body does not have any linear damping.

	for point in range(arch_num_points):
		velocity.y += gravity * delta
		pos += velocity * delta
		
		line_arch.set_point_position(point, pos - get_global_position())

But how can I extend the script to also use damping?

Damping per physics step is: -kv

Thanks! Its working fine now.

	for point in range(arch_num_points):
		velocity.y += gravity * delta
		
		velocity.x -= linear_damp*velocity.x*delta
		velocity.y -= linear_damp*velocity.y*delta
		
		pos += velocity * delta
		
		line_arch.set_point_position(point, pos - get_global_position())
