Raycast Not Working
Hey all,
I'm trying to make an object (with a box collider) interact with a click to exit out of a while loop using a Raycast. However, although I think I have all the components necessary to initiate it, nothing happens when I click on the object, and the while loop keeps looping. The snippet of code follows:
public IEnumerator Qone()
{
t.text = "A: 1";
while (i == 0)
{
Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
RaycastHit hit;
if (Input.GetMouseButtonDown(0))
{
if (Physics.Raycast(ray, out hit))
{
if (hit.transform.name == "A")
{
Debug.Log("hit");
i = 1;
}
}
}
Debug.Log("F");
yield return null ;
}
i = 0;
StopAllCoroutines();
}
Your code works for me. Can you post a screenshot of your Hierarchy and Inspector of the object in question?
@Ymrasu Yes, here they are. The object in question is "A." (Don't $$anonymous$$d how unorganized they are)
I've solved it! For some reason, Box Collider 2D doesn't work with Raycast, so putting a normal Box Collider on the object fixed the problem. Thanks for your help.
Works perfectly for me. Are you sure your object you clicked on is named "A"?
Yes, the object is named A. However, this script is attached onto the "A" object; does that make a difference?
Physics.Raycast returns the first thing it hits. If you happen to have anything in front of 'A' or if your B, C, and D all have box colliders as well, they could be the ones getting hit.
Try Physics.RaycastAll:
public IEnumerator Qone()
{
//t.text = "A: 1";
while (i == 0) {
if (Input.GetMouseButtonDown(0)) {
Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
RaycastHit[] hits = Physics.RaycastAll(ray);
foreach(var hit in hits) {
if (hit.transform.name == "A") {
Debug.Log("hit");
i = 1;
}
}
}
Debug.Log("F");
yield return null;
}
i = 0;
StopAllCoroutines();
}
@Ymrasu Thanks for responding. However, I tried using this method and sadly the result was the same as before. I even tried making another scene using this code and just one object, but it still did not work. Do you think it might be a problem with my editor?
Is this how you want the object to behave? Behaviour GIF
@xBlackhawk Yes, the only difference is that I'm using Unity2d.
