Set integer to new random value every time Update() runs
Hello! I am trying to have the value of an integer change randomly to either 0 or 1 every time a specific if statement within Update() is run, but the integer only seems to change the first time the if statement is run. I have already defined the integer at the beginning of the code, and I have also tried including hand_visible=1; within Start () to initialize it. Any help would be greatly appreciated!
Ex.
Update ()
if ((reset == true) && trial < 25)
{
hand_visible = Random.Range(0,2);
}
Have you verified that the if statement is being called correctly?
Yes, the actual if statement is below and I can confirm that a new trial starts and the cube disappears. Even if I set hand_visible to an integer like 1 in this if statement an to a different integer in a separate if statement within Update(), the value of hand_visible does not seem to change
if ((tip.transform.position).magnitude <= .5 * r && (reset == true) && trial < 25)
{
hand_visible = 1;
reset = false;
theta = ((expOrder[trial, 0] + 1) * 20 + 30) * $$anonymous$$athf.PI / 180f;
Ball.Instance.gameObject.transform.localScale = new Vector3(0.025f, 0.025f, 0.025f);
Destroy(Cube.Instance.gameObject);
Ball.Instance.gameObject.transform.position = new Vector3(r * $$anonymous$$athf.Cos(theta), 0, r * $$anonymous$$athf.Sin(theta));
All I can say currently is that I am quite sure hand_visible = Random.Range(0,2); works correctly, the only issue I can imagine is there is something else happening.
Can you confirm you are triggering the if statement? A Debug.Log("Triggered"); Should do
Thank you for your help! There is a lot of commented out stuff that I have tried to do, but ultimately the hand_visible integer is not getting updated when the if statement is called. The ultimate goal is to have the hand prefab's mesh turn on/off randomly for each trial.
