public class Example : MonoBehaviour { // Casts a ray from (0,0,0) towards (0,0,1) to the infinity and prints a message // if any object has touched the ray. // To test it, just place any object and intersect it with the white drawn line

void Update() { // shows the line that follows the ray. Debug.DrawLine(Vector3.zero, Vector3.forward * 100); if (Physics.Raycast(Vector3.zero, Vector3.forward, Mathf.Infinity)) { print("There is something in front of the object!"); } } }
