Hi guys, i am working on a Sub-System, a road creation in a simCity way. i am in a phase of experimentation, i know the basics, so here is my question.
i am using a function named mousePosition,with raycasting. i create a mesh dinamicaly(4 vertices), The idea is simple, i made 1 click and CreateRoad is called. The center of the mesh is exactly where the mouse was clicked. the road lenght is 4.
Alpha(4Pix)-------Beta(0pix)
imagine the road with both extremes Alpha and Beta. the center is on B.
i want to rotate Alpha toward the mouse location. point Beta must be fixed and A always have to be looking at mouse location. My problem is that my road rotates with Beta looking the mouse location, not Alpha.The road rotates complete, not with a fixed point. i have tried to add a GameEmpty like a parent but i cant separate the Transform from the road mesh becouse there is no option to do this from Unity. i have tried a lot of codes and i dont get it to work, i have readed a lot of post too. here is the complete script with comments.
i would love to know if somebody knows how to do it correctly. Thanks a lot, and hope you understand my question. Image beneath.

Vector3[] vertices = new Vector3[]
{

new Vector3(-1, 0, -5),

int[] triangles = new int[]

Vector2[] uv = new Vector2[]

new Vector2(1, 1),
new Vector2(1, 0),
new Vector2(0, 1),

Vector3[] normals={

};
mesh= new Mesh();
mesh.vertices=vertices;
mesh.triangles=triangles;
mesh.uv=uv;
mesh.normals=normals;
mesh_filter=road.GetComponent<MeshFilter>();

}
}
i have tried a lots of code that doesnt work properly.
