Question
How do I detect collision, when using custom_integrator?
Problem
Inside my func _integrate_forces I move the rigid body with state.linear_velocity = velocity with velocity being: velocity = Vector3(2, 0, 0).
Once it hits a collision shape it stops, while I expect it to change direction whenever it detects a collision. It appears that the rigidBody somehow detects it can not move forward, but doesnt really detect a “colission”, since I’m not getting any integers from state.get_contact_count(). Below is my code:
extends RigidBody3D
@export var velocity: Vector3 = Vector3(2, 0, 0)
func _ready() -> void:
#Schaltet die eingebaute Physik aus und gibtuns volle Kontrolle
#Node muss initialisiert sein, deswegen in _ready()
#Es gibt eine physics und idle processing. Idle läuft jeden Frame, Physics läuft 60 iterations/minute
custom_integrator = true
func _integrate_forces(state: PhysicsDirectBodyState3D) -> void:
state.linear_velocity = velocity
if state.linear_velocity != Vector3.ZERO:
print("I am still going")
#counts the amount of object hit in one frame
for i in range(state.get_contact_count()):
#counts what object it hit and changes behavior based on that
print("Detected collision, " + str(i))
var id = state.get_contact_collider_id(i)
print("This is the id: " + str(id))
var collider = state.get_contact_collider_object(i)
if collider:
print("touched")
velocity = -velocity
break
func _physics_process(delta: float) -> void:
pass
