how to use a raycast in unity code example
Example 1: raycast unity
RaycastHit hit;
if (Physics.Raycast(transform.position, transform.TransformDirection(Vector3.forward), out hit, Mathf.Infinity, layerMask))
{
Debug.DrawRay(transform.position, transform.TransformDirection(Vector3.forward) * hit.distance, Color.yellow);
Debug.Log("Hit");
}
else
{
Debug.DrawRay(transform.position, transform.TransformDirection(Vector3.forward) * 1000, Color.white);
Debug.Log("No Hit");
}
Example 2: unity raycast
void Update()
{
int layerMask = 1 << 8;
layerMask = ~layerMask;
RaycastHit hit;
if (Physics.Raycast(transform.position, transform.TransformDirection(Vector3.forward), out hit, Mathf.Infinity, layerMask))
{
Debug.DrawRay(transform.position, transform.TransformDirection(Vector3.forward) * hit.distance, Color.yellow);
Debug.Log("Did Hit");
}
else
{
Debug.DrawRay(transform.position, transform.TransformDirection(Vector3.forward) * 1000, Color.white);
Debug.Log("Did not Hit");
}
}
