Unity Step on the pit to learn a little knowledge

Draw a cube dashed line in the editor 、 Sphere dotted line (Gizmos Auxiliary wireframe )

Use Gizmos Class allows us to Unity An auxiliary wireframe is implemented in , Here are some common wireframes .

added API You can come The official manual is about Gizmos see

Use Gizmos Drawing wireframe is used in the following two functions ：

private void OnDrawGizmos(){   Debug.Log(" Keep calling " );}private void OnDrawGizmosSelected(){    Debug.Log("selected, Only when the object is selected, it is called " );}

You can also use Gizmos.color Color change .

Be careful ： Under normal circumstances, only in Scene See wireframe in , stay Game To open... In the view Gizmos Before you can see the wireframe

The dashed boxes of cube and sphere are as follows ：

    private void OnDrawGizmos()    {        Gizmos.color = Color.green;// Change the color of the wireframe         Gizmos.DrawWireCube(transform.position, new Vector3(3, 3, 3));// Cube dashed box         Gizmos.DrawWireSphere(transform.position, 5f);// Sphere dashed box     }

The cube and sphere wireframes are as follows ：

    private void OnDrawGizmos()    {        Gizmos.color = Color.green;// Change the color of the wireframe         Gizmos.DrawCube(transform.position, new Vector3(3, 3, 3));// Cube wireframe         Gizmos.DrawSphere(transform.position, 5f);// Sphere wireframe     }
