How to divide circle & set color for each path ?

Hello everybody,

I have a problem . I want create a circle & divide this to three path,set color for each path. How to make this?
Thanks !




Thanks

 

Please, help me !

 

in 2D?

- create a procedural Mesh circle with triangles that have one vertex in the center
- weight the arcs of the triangles by your percentages
- if an arc is larger than a certain degree amount you create a new triangle

 

Right, Nice...Thank you

But How to create a circle from the triangle ??

 

It's called a pie chart, btw.

Meshes are made in unity with http://docs.unity3d.com/ScriptReference/Mesh.html

 

I got some code that may help you. I use it to visualize an attack Cone with a procedural mesh, i just post it here, you have to make it work for you, but it should look like the pink cone in this gif if you make it work:

Code (CSharp):

1. //Cone Mesh
2.     private    static GameObject    attackCone;
3.     private    static Mesh            coneMesh;
4.     //public    Material        coneMat;
5.            
6.     private    void CreateAttackCone(){    //create a new cardPrefab procedurally    and a selection border
7.        
8.         attackCone                        = new GameObject();
9.         attackCone.transform.position    = Vector3.zero;//pos;    //not important
10.         attackCone.transform.name        = "AttackCone";
11.        
12.     //Card
13.         coneMesh                = attackCone.AddComponent<MeshFilter>().mesh;
14.         /*MeshRenderer coneMeshR    = */attackCone.AddComponent<MeshRenderer>();
15.         //coneMeshR.material        = coneMat;
16.        
17.         int vertCount = 19;
18.                                    
19.         //coneMesh.Clear();
20.         Vector3[]    vertices    = new Vector3    [vertCount];
21.         //Color[]        colors        = new Color        [vertCount];
22.         Vector2[]    uv            = new Vector2    [vertCount];
23.         Vector3[]    normals        = new Vector3    [vertCount];
24.         int[]        triangles    = new int        [(vertCount-1)*3];
25.         Vector4[]    tangents    = new Vector4    [vertCount];
26.                            
27.         for(int i = 0; i<vertCount-1; i++){
28.            
29.             vertices[ i]    = Vector3.zero;
30.            
31.             if(i<vertCount-2){
32.                 triangles[i*3+0]    = 0;
33.                 triangles[i*3+1]    = i+1;
34.                 triangles[i*3+2]    = i+2;
35.             }else{
36.                 triangles[i*3+0]    = 0;
37.                 triangles[i*3+1]    = i+1;
38.                 triangles[i*3+2]    = 1;
39.             }
40.                    
41.         }
42.        
43.         for(int i = 0; i<vertCount; i++){            
44.             uv[i]        = new Vector2(vertices[i].x, vertices[i].z);
45.             tangents[i]    = Vector4.zero;
46.         }                    
47.        
48.         coneMesh.vertices    = vertices;
49.         coneMesh.uv            = uv;
50.         coneMesh.tangents    = tangents;
51.         coneMesh.normals    = normals;
52.         coneMesh.triangles    = triangles;
53.        
54.         coneMesh.RecalculateNormals();
55.         coneMesh.RecalculateBounds();
56.     }
57.    
58.     private    static void UpdateCone(float range, float coneAngle){
59.        
60.         float angle        = -coneAngle/2F;
61.         Vector3[]    vertices    = new Vector3    [coneMesh.vertices.Length];
62.        
63.         for(int i = 1; i<vertices.Length; i++){            
64.             vertices[ i]    = Quaternion.Euler(0, angle, 0)    *(Vector3.forward*range);
65.             angle += coneAngle/(vertices.Length-1);
66.         }
67.         coneMesh.vertices    = vertices;
68.     }

Thank ! I'm trying...
