So, I'm working on an IEnumerator() that is called to spawn objects in a fountain style (kinda flying up and out and landing at a random spot nearby). I feel like I had this working for a hot minute, but I don't know what I've done to screw it up. It's POSSIBLE that it was only working when it was a void() instead, but I need to function to be a coroutine (or otherwise run on something other than the main thread).
So, I have this. It works, except you only see the spawned objects after they've landed and the function has exited.
public IEnumerator ThrowFountain()
{
System.Random rnd = new
System.Random(System.Guid.NewGuid().GetHashCode());
GameObject _go = Transform.Instantiate(go, t.position, Quaternion.identity);
_go.transform.parent = t.parent.transform;
_go.transform.position = t.position + new Vector3(0.0f, 1.5f, 0.0f);
float trajectoryHeight = rnd.Next(3,6);
bool closeEnough = false;
Vector3 startVec = _go.transform.position;
Vector3 newVec = new Vector3 (t.position.x + rnd.Next(-6,6), t.position.y, t.position.z + rnd.Next(-6,6));
float distance = Vector3.Distance(startVec, newVec);
float startTime = Time.timeSinceLevelLoad;
float evalTime = startTime;
while (!closeEnough)
{
float distCovered = (evalTime - startTime) * speed;
float fracJourney = distCovered / distance;
Vector3 currPos = Vector3.Lerp(startVec, newVec, fracJourney);
currPos.y += trajectoryHeight * Mathf.Sin(Mathf.Clamp01(distCovered) * Mathf.PI);
_go.transform.position = currPos;
closeEnough = V3Close(currPos, newVec, 1.0f);
Debug.Log("Time: " + Time.time.ToString());
evalTime += Time.deltaTime;
}
yield return new WaitForEndOfFrame();
}
V3Close() just returns a bool so long as none of the vectors of the object and it's target are more than 1.0f apart. That part seems to be working as well. Not sure if maybe the IEnumerator loop won't draw the object (because it's not on the main thread or for some other reason)?
