Hey guys,
I tried to create a flat mesh on my own, just like the terrain, but so i can change its vertices height in each Update()-Call (to create something wave-like).
I’m pretty sure I created the rectangles right (there are no errors anymore) and even the pivot in Scene-View moves when I hit start.
But the mesh turns out to be invisible, even in “Wireframe”-Mode, from all directions (so i guess its not the normals). Also i got a material ‘Diffuse’ with a Texture on it.
I have the feeling I’m missing something simple, any suggestions?
Here’s the code, still in Start(), because I don’t need to transform it yet. I just want it visible. Possibly the uv’s?
public class Waves : MonoBehaviour {
private int width = 4;
private int maxRows = 1; //Minimum 1
private float distance = 2f;
public bool showInformation = true;
public bool showDetailed = true;
void Start() {
if(maxRows < 1)
maxRows = 1;
//Building Vertex-Grid
List<Vector3> vertices = new List<Vector3>();
for (int row = 0; row <= maxRows; row++){
if(row%2 == 0){
for (int i = 1; i <= width ; i++ ){
vertices.Add(new Vector3(i*distance, 0f, row* distance));
}
} else {
for (int i = 1; i <= width ; i++ ){
vertices.Add(new Vector3(i*distance + distance*0.5f, 0f, row* distance));
}
}
}
//Convert List<Vector3> to Vector3[]
Vector3 [] allVertices = new Vector3[vertices.Count];
for (int i = 0; i < vertices.Count; i++) {
allVertices _= vertices*;*_

I also uploaded the concept for creation of the triangles:
