Question
I’m trying to make a custom car physics using raycasts to move a rigid body. I’ve watch every video about it but I can’t quite figure it out since most of them are on Godot 3
This is what I’m trying to achieve:
This is what I have right now:
It jitters, doesn’t go all the way up. Can anyone please help me with that? This is my code:
Wheel code:
func _physics_process(delta):
getVect()
if is_on_ground():
var collision_point = to_local(raycast.get_collision_point())
var ray_target = raycast.target_position
#offset from desired spring length
displacement = ray_target - collision_point
#used by parent to apply force
susp_force = (displacement * susp_power) - (-wheelVector * susp_damp)
func is_on_ground():
return raycast.is_colliding()
func getVect():
var diff = get_global_position() - last_pos
wheelVector = diff.normalized()
last_pos = get_global_position()
Car code:
func _physics_process(delta):
for i in wheels.size():
if wheels[i].is_on_ground():
var wheel_point = wheels[i].position
var susp_force = wheels[i].susp_force
var wheel_displacement = wheels[i].displacement
#to hold the car
apply_central_impulse(-wheel_displacement * 1200 * delta)
#suspention activation
apply_impulse(-susp_force, wheel_point)
