3、关键代码

一、简单介绍

UGUI，是Unity自带的 GUI 系统，有别于 NGUI；使用 UGUI 也能制作出比较酷炫的效果。

本节介绍，在 UGUI中普通的 UI 元素中实现简单的多边形显示的若干方法的整理总结。

UGUI 的 UI 扩展，可参见 unity-ui-extensions 工程学习： https://bitbucket.org/ddreaper/unity-ui-extensions

接下来将逐一说明几种多边形UI的方法。

二、可以自由调整形状的多边形 UI

1、功能说明

1)添加脚本 PolygonUIMesh

2）在该脚本的组建下，添加子物体，作为 Polygon 多边形的点

3）任意移动子物体，Polygon 多边形都会穗子变化

3、效果预览

3、实现步骤

1）编写好脚本 PolygonUIMesh

2）挂在 PolygonUIMesh 脚本到 Canvas 下的物体上

（注意：PolygonUIMesh 相当于 Button 的 Image，所以可以在其组建上添加 Button，实现按钮功能等）

3）在挂载 PolygonUIMesh 脚本组件下，添加子物体，会自动作为多变形的点，移动他们既可以跳帧多边形形状了

4、关键代码

using UnityEngine;
using System.Collections;
using UnityEngine.UI;public class PolygonUIMesh : Graphic
{private void OnGUI(){// 实时检测更新绘制 OnPopulateMesh 中 transform.child 位置SetAllDirty();}/// <summary>/// 根据 transform.child 位置 绘制 Mesh/// </summary>/// <param name="vh"></param>protected override void OnPopulateMesh(VertexHelper vh){if (transform.childCount <= 2){return;}Color32 color32 = color;vh.Clear();// 几何图形的顶点，本例中根据子节点坐标确定顶点foreach (Transform child in transform){vh.AddVert(child.localPosition, color32, new Vector2(0f, 0f));}for (int i = 0; i < (transform.childCount-2); i ++){// 几何图形中的三角形vh.AddTriangle(i+1, i + 2, 0);} }/// <summary>/// 点的辅助绘制/// </summary>private void OnDrawGizmos(){if (transform.childCount == 0){return;}for (int i = 0; i < transform.childCount; i++){Gizmos.DrawSphere(transform.GetChild(i).position, 2.55f);Gizmos.DrawIcon(transform.GetChild(i).position, "numbers/numbers_" + i+".PNG",false);}}
}

三、调整对应边数，实现任意正多边形，甚至圆形 UI

1、功能介绍

1）这里是继承 RawImage，调整其多边形的绘制

2）改变边数，实现 UI 多边形

3）调整 UI 元素宽高，效果会有不一样（局限性）

2、效果预览

3、实现步骤

1）编写脚本 UIPolygonRawImage ，继承 RawImage ，重写其方法，实现多边形UI

（其中：UIPolygonRawImageInspector 脚本是对 UIPolygonRawImage 变量显示的调整，放在 Editor 目录下即可）

（UIPolygonRawImageInspector 可以根据需要可要可不要，不影响功能）

2）在 Canvas 下添加组件，并挂载脚本 UIPolygonRawImage ，对应添加图片

（跟使用 RawImage差不多，只是多了个边数）

3）调整边数，实现多边形 UI

4、关键代码

参考博文：https://www.xuanyusong.com/archives/4375

1）UIPolygonRawImage

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;public class UIPolygonRawImage : RawImage
{const int FILL_PERCENT = 100;float thickness = 5;[SerializeField][Range(4, 360)]int _segments = 36;public int segments{get { return _segments; }set{if (_segments != value){_segments = value;SetVerticesDirty();
#if UNITY_EDITORUnityEditor.EditorUtility.SetDirty(transform);
#endif}}}protected override void OnRectTransformDimensionsChange(){base.OnRectTransformDimensionsChange();this.thickness = (float)Mathf.Clamp(this.thickness, 0, rectTransform.rect.width / 2);}protected override void OnPopulateMesh(VertexHelper vh){float outer = -rectTransform.pivot.x * rectTransform.rect.width;float inner = -rectTransform.pivot.x * rectTransform.rect.width + this.thickness;vh.Clear();Vector2 prevX = Vector2.zero;Vector2 prevY = Vector2.zero;Vector2 uv0 = new Vector2(0, 0);Vector2 uv1 = new Vector2(0, 1);Vector2 uv2 = new Vector2(1, 1);Vector2 uv3 = new Vector2(1, 0);Vector2 pos0;Vector2 pos1;Vector2 pos2;Vector2 pos3;float tw = rectTransform.rect.width;float th = rectTransform.rect.height;float angleByStep = (FILL_PERCENT / 100f * (Mathf.PI * 2f)) / segments;float currentAngle = 0f;for (int i = 0; i < segments + 1; i++){float c = Mathf.Cos(currentAngle);float s = Mathf.Sin(currentAngle);StepThroughPointsAndFill(outer, inner, ref prevX, ref prevY, out pos0, out pos1, out pos2, out pos3, c, s);uv0 = new Vector2(pos0.x / tw + 0.5f, pos0.y / th + 0.5f);uv1 = new Vector2(pos1.x / tw + 0.5f, pos1.y / th + 0.5f);uv2 = new Vector2(pos2.x / tw + 0.5f, pos2.y / th + 0.5f);uv3 = new Vector2(pos3.x / tw + 0.5f, pos3.y / th + 0.5f);vh.AddUIVertexQuad(SetVbo(new[] { pos0, pos1, pos2, pos3 }, new[] { uv0, uv1, uv2, uv3 }));currentAngle += angleByStep;}}private void StepThroughPointsAndFill(float outer, float inner, ref Vector2 prevX, ref Vector2 prevY, out Vector2 pos0, out Vector2 pos1, out Vector2 pos2, out Vector2 pos3, float c, float s){pos0 = prevX;pos1 = new Vector2(outer * c, outer * s);pos2 = Vector2.zero;pos3 = Vector2.zero;prevX = pos1;prevY = pos2;}protected UIVertex[] SetVbo(Vector2[] vertices, Vector2[] uvs){UIVertex[] vbo = new UIVertex[4];for (int i = 0; i < vertices.Length; i++){var vert = UIVertex.simpleVert;vert.color = color;vert.position = vertices[i];vert.uv0 = uvs[i];vbo[i] = vert;}return vbo;}
}

2）UIPolygonRawImageInspector

using System.Collections;
using System.Collections.Generic;
using UnityEditor;
using UnityEditor.UI;
using UnityEngine;[CustomEditor(typeof(UIPolygonRawImage), true)]
[CanEditMultipleObjects]
public class UIPolygonRawImageInspector : RawImageEditor
{public override void OnInspectorGUI(){base.OnInspectorGUI();UIPolygonRawImage polygon = target as UIPolygonRawImage;polygon.segments = Mathf.Clamp(EditorGUILayout.IntField("UICircle多边形", polygon.segments), 4, 360);}
}

四、类雷达图的多边形 UI

1、功能说明

1）查看UGUI的代码可以得知，绘制ui图的方法其实是绘制mesh，然后对其进行填充。正常一个Image图片，绘制有四个顶点。为了实现多边形，继承于MaskableGraphic，重写OnPopulateMesh，重新绘制顶点。

2）能调整边数，点的比例，是否填充，旋转等，控制显示雷达图的样式

2、效果预览

3、实现步骤

1）编写脚本，实现类雷达图的功能

2）把脚本挂载到Canvas 的组建下

3）调整脚本参数，即可根据需要调整成自己想要的样式

4、关键代码

}

六、雷达图 UGUI 案例

参考博文：Unity---UGUI案例学习---雷达图

1、效果图

2、Unity 场景布局

（这里的方法是通过改变黄色区域UI元素的外围顶点位置，来实现出我们需要的渲染效果。）

3、关键代码

（Point是蓝色区域最外的顶点，只需执行一次获得其具体位置就行。Handler是红色的顶点，每次更新时都要同步更新）

1）Boke_RadarChart（黄色区域雷达图类）

public class Boke_RadarChart : Image{//顶点个数、顶点位置、顶点大小、顶点显示图片、顶点颜色[SerializeField]private int _pointCount;[SerializeField]private List<RectTransform> _points;[SerializeField]private Vector2 _pointSize = new Vector2(10, 10);[SerializeField]private Sprite _pointSprite;[SerializeField]private Color _pointColor = Color.white;//每个方向上各个点的的比例、存储handler[SerializeField]private float[] _handlerRadio;[SerializeField]private List<S5RadarChartHandler> _handlers;private void Update(){//刷新SetVerticesDirty();}protected override void OnPopulateMesh(VertexHelper vh){//修改原来的空image，让他填满我们的雷达图。//清空原来顶点，自己添加vh.Clear();AddVerts(vh);//AddVertsTemplete(vh);AddTriangle(vh);}/// <summary>/// 添加顶点/// </summary>private void AddVerts(VertexHelper vh){//添加轴心点vh.AddVert(Vector3.zero, color, Vector2.zero);foreach (S5RadarChartHandler handler in _handlers){vh.AddVert(handler.transform.localPosition, color, Vector2.zero);}}/*/// <summary>/// 如果需要用贴图。就要每个顶点单独设置uv坐标/// </summary>private void AddVertsTemplete(VertexHelper vh){vh.AddVert(_handlers[0].transform.localPosition, color, new Vector2(0.5f, 1));vh.AddVert(_handlers[1].transform.localPosition, color, new Vector2(0f, 1));vh.AddVert(_handlers[2].transform.localPosition, color, new Vector2(0f, 0));vh.AddVert(_handlers[3].transform.localPosition, color, new Vector2(1f, 0));vh.AddVert(_handlers[4].transform.localPosition, color, new Vector2(1f, 1));}*//// <summary>/// 添加三角形/// </summary>private void AddTriangle(VertexHelper vh){//围绕中心点生成5个面for (int i = 1; i < _pointCount; i++){//用三个顶点组成一个三角面//顺时针vh.AddTriangle(0, i + 1, i);}vh.AddTriangle(0, _pointCount, 1);}public void InitPoint(){ClearPoints();_points = new List<RectTransform>();SpawnPoint();SetPointPos();}private void ClearPoints(){if (_points == null)return;foreach (RectTransform point in _points){if (point != null)//编辑模式下要用这个DestroyImmediate(point);}}private void SpawnPoint(){//5个最边角的顶点for (int i = 0; i < _pointCount; i++){GameObject point = new GameObject("Point" + i);point.transform.SetParent(transform);_points.Add(point.AddComponent<RectTransform>());}}private void SetPointPos(){//每个角的弧度float radian = 2 * Mathf.PI / _pointCount;//半径float radius = 100;//从最上面一个顶点开始算。以中心为原点。float curRadian = 2 * Mathf.PI / 4.0f;for (int i = 0; i < _pointCount; i++){float x = Mathf.Cos(curRadian) * radius;float y = Mathf.Sin(curRadian) * radius;curRadian += radian;_points[i].anchoredPosition = new Vector2(x, y);}}public void InitHandlers(){ClearHandlers();_handlers = new List<S5RadarChartHandler>();SpawnHandlers();SetHandlerPos();}private void ClearHandlers(){if (_handlers == null)return;foreach (S5RadarChartHandler handler in _handlers){if (handler != null)DestroyImmediate(handler.gameObject);}}private void SpawnHandlers(){S5RadarChartHandler handler = null;for (int i = 0; i < _pointCount; i++){GameObject point = new GameObject("Handler" + i);point.AddComponent<RectTransform>();point.AddComponent<Image>();handler = point.AddComponent<S5RadarChartHandler>();handler.SetParent(transform);handler.ChangeSprite(_pointSprite);handler.ChangeColor(_pointColor);handler.SetSize(_pointSize);handler.SetScale(Vector3.one);_handlers.Add(handler);}}private void SetHandlerPos(){//默认的handler位置，就是5项属性全满。if (_handlerRadio == null || _handlerRadio.Length != _pointCount){for (int i = 0; i < _pointCount; i++){_handlers[i].SetPos(_points[i].anchoredPosition);}}else{for (int i = 0; i < _pointCount; i++){_handlers[i].SetPos(_points[i].anchoredPosition * _handlerRadio[i]);}}}}

2）Boke_RadarChartHandler（红色顶点类）

public class Boke_RadarChartHandler : MonoBehaviour{private Image _image;private Image Image{get{if (_image == null)_image = GetComponent<Image>();return _image;}}private RectTransform _rect;private RectTransform Rect{get{if (_rect == null)_rect = GetComponent<RectTransform>();return _rect;}}#region 封装一层public void SetParent(Transform parent){transform.SetParent(parent);}public void ChangeSprite(Sprite sprite){Image.sprite = sprite;}public void ChangeColor(Color color){Image.color = color;}public void SetPos(Vector2 pos){Rect.anchoredPosition = pos;}public void SetSize(Vector2 size){Rect.sizeDelta = size;}public void SetScale(Vector3 scale){Rect.localScale = scale;}private float GetScale(){return Rect.lossyScale.x;}#endregion}

3）Boke_RadarChartEditor

（编辑器类，用于把Boke_RadarChart类中的可变属性显示到面板中，方便我们更改调试。）

using System.Collections;using System.Collections.Generic;using UnityEngine;using UnityEditor;[CustomEditor(typeof(Boke_RadarChart), true)][CanEditMultipleObjects]public class Boke_RadarChartEditor : UnityEditor.UI.ImageEditor{SerializedProperty _pointCount;SerializedProperty _pointSprite;SerializedProperty _pointColor;SerializedProperty _pointSize;SerializedProperty _handlerRadio;protected override void OnEnable(){base.OnEnable();_pointCount = serializedObject.FindProperty("_pointCount");_pointSprite = serializedObject.FindProperty("_pointSprite");_pointColor = serializedObject.FindProperty("_pointColor");_pointSize = serializedObject.FindProperty("_pointSize");_handlerRadio = serializedObject.FindProperty("_handlerRadio");}public override void OnInspectorGUI(){base.OnInspectorGUI();serializedObject.Update();EditorGUILayout.PropertyField(_pointCount);EditorGUILayout.PropertyField(_pointSprite);EditorGUILayout.PropertyField(_pointColor);EditorGUILayout.PropertyField(_pointSize);EditorGUILayout.PropertyField(_handlerRadio,true);Boke_RadarChart radar = target as Boke_RadarChart;if (radar != null){if (GUILayout.Button("生成雷达图顶点")){radar.InitPoint();}if (GUILayout.Button("生成内部可操作顶点")){radar.InitHandlers();}}serializedObject.ApplyModifiedProperties();if (GUI.changed){EditorUtility.SetDirty(target);}}}
