I have made a function to make flat disk. the weird thing is: it works with some input parameters but doesn’t with others. when it doesn’t work it doesn’t give any errors, just nothing shows up.

this is my Code:

```
public Mesh Disk(int radius,int radiusTiles,int tilesAround)
{
Vector3[] vertices = new Vector3 [radiusTiles*tilesAround*6];
Vector3[] triangles = new int [radiusTiles*tilesAround*6];
Vector3[] UV = new Vector2 [radiusTiles*tilesAround*6];
int currentVertex = 0;
float tileLength = radius / radiusTiles; //the length of a tile parallel to the radius
float radPerTile = 2 * Mathf.PI / tilesAround; //the radians the tile takes
for(int angleNum = 0; angleNum < tilesAround; angleNum++)//loop around
{
float angle = radPerTile*angleNum; //the current angle in radians
for(int offset = 0; offset < radiusTiles; offset++)//loop from the center outwards
{
vertices[currentVertex] = new Vector3(Mathf.Cos(angle)*offset*tileLength , Mathf.Sin(angle)*offset*tileLength ,0);
vertices[currentVertex + 1] = new Vector3(Mathf.Cos(angle + radPerTile)*offset*tileLength , Mathf.Sin(angle + radPerTile)*offset*tileLength ,0);
vertices[currentVertex + 2] = new Vector3(Mathf.Cos(angle)*(offset + 1)*tileLength , Mathf.Sin(angle)*(offset + 1)*tileLength ,0);
vertices[currentVertex + 3] = new Vector3(Mathf.Cos(angle + radPerTile)*offset*tileLength , Mathf.Sin(angle + radPerTile)*offset*tileLength ,0);
vertices[currentVertex + 4] = new Vector3(Mathf.Cos(angle + radPerTile)*(offset + 1)*tileLength , Mathf.Sin(angle + radPerTile)*(offset + 1)*tileLength ,0);
vertices[currentVertex + 5] = new Vector3(Mathf.Cos(angle)*(offset + 1)*tileLength , Mathf.Sin(angle)*(offset + 1)*tileLength ,0);
currentVertex += 6;
}
}
for(int j = 0; j < triangles.Length; j++) //set the triangles
{
triangles[j] = j;
}
//create the mesh and apply vertices/triangles/UV
Mesh disk = new Mesh();
disk.vertices = vertices;
disk.triangles = triangles;
disk.RecalculateNormals();
disk.uv = UV; //the UV doesnt need to be set
return disk;
}
```

for example:

Disk (5, 7, 15);

doesn’t work, but:

Disk (4, 4, 15);

does.

If anyone knows what i’m doing wrong it would be really helpfull.

**Edit:**

changed

float tileLength = radius / radiusTiles;

into

float tileLength = (float)radius / (float)radiusTiles;

and:

float angle = radPerTile*angleNum;

into

float angle = (float)radPerTile*(float)angleNum;
