测试代码
public class CollisionTest : MonoBehaviour
{
void Update()
{
if (Input.GetMouseButtonDown(0))
{
if (Physics.SphereCast(Vector3.zero, 0.5f, Vector3.forward, out var hitInfo, 5))
{
Debug.Log($"hit: {hitInfo.point.x},{hitInfo.point.y},{hitInfo.point.z}");
}
}
}
void OnDrawGizmos()
{
Gizmos.color = Color.cyan;//更改颜色
Gizmos.DrawLine(Vector3.zero, Vector3.forward * 5);
}
}
检测范围
1) 从原点+半径距离开始，半径为0.5的圆柱体射线，
2) 排除掉一开始的0.5半径的球形（灰色那个）
