Can use FixedUpdate in Update?
Hi, it's my code
void Update () {
if (Input.GetKey (KeyCode.J)) {
GetComponent<Rigidbody2D> ().velocity = new Vector2 (5,0);
}
}
but the problem is that we should get inputs in Update and use all object that have Rigidbody2D in FixedUpdate
how can I get input in Update and then use RigidBody2D to move the object in FixedUpdate?
???

You can use a class level variable to separate your concerns. Also you should cache your Rigidbody2D for performance:
Vector2 force;
Rigidbody2D rb2d;
void Awake () {
rb2d = GetComponent<Rigidbody2D> ();
}
void Update () {
if (Input.GetKey (KeyCode.J)) {
force = new Vector2 (5, 0);
} else {
force = Vector2.zero;
}
}
void FixedUpdate () {
rb2d.velocity = force;
}
