구를그림

    void OnDrawGizmos()
    {
        Gizmos.DrawWireSphere(transform.position, radius);
    }

 

가려지지 않는 구를 그림

    void OnDrawGizmos()
    {
#if UNITY_EDITOR
        UnityEditor.Handles.DrawWireDisc(transform.position, transform.up, radius);
        UnityEditor.Handles.DrawWireDisc(transform.position, transform.right, radius);
        UnityEditor.Handles.DrawWireDisc(transform.position, transform.forward, radius);
#endif
    }

 

 

원을 그림

void OnDrawGizmos()
{
    UnityEditor.Handles.DrawWireDisc(transforms[i].position, fowordAngle * Vector3.up, radius);
}

 

텍스트 표시

#if UNITY_EDITOR
        void OnDrawGizmos()
        {
            UnityEditor.Handles.Label(transform.position, "text");
        }
#endif

 

폰트설정한 텍스트 표시

var guiStyle = new GUIStyle();
guiStyle.alignment = TextAnchor.MiddleCenter; //왜인지 UpperLeft로만 된다
guiStyle.fontSize = 48;
guiStyle.normal.textColor = color;
UnityEditor.Handles.Label(transform.position, "text", guiStyle);

콜라이더를 그림

    void DrawColliderGizmo(Transform transform)
    {

컬러적용

Gizmos.color = Color.red;
{
    Gizmos.DrawLine(cameraPosition.position, thirdPersonPoint.position);
}
Gizmos.color = Color.white;

 

 

 

선택된 상태에서만 기즈모를 그림

void OnDrawGizmosSelected()
{
    //기즈모를 그림
}

혹은

#if UNITY_EDITOR
        if (Selection.transforms.Contains(transform))
        {
            //기즈모를 그림
        }
#endif

 

 

 

화살표 표시 (arrow)

#if UNITY_EDITOR
Handles.color = Handles.xAxisColor;
UnityEditor.Handles.ArrowHandleCap(0, transform.position, transform.rotation * Quaternion.Euler(0, 90, 0), size: 0.25f, EventType.Repaint);
Handles.color = Handles.yAxisColor;

EditorWindow에서 그릴때

Debug 계열만 됨

void OnGUI()
{
    if (armTransform != null)
    {
        Debug.DrawLine(armTransform.position, armTransform.position+Vector3.forward,Color.red);
    }
}
void Update()
{
    Repaint();
}
