Modify one face of a game object cube

I am working on a maze game with a cube walking around, collecting keys, entering portals and dodging traps… The problem is the players find it hard to find the cube “face” at the beginning… This is because I am using this script for moving the cube:

if (Input.GetKey (KeyCode.UpArrow)) {
            transform.Translate (Vector3.forward * moveSpeed * Time.deltaTime);
        }

        if (Input.GetKey (KeyCode.DownArrow)) {
            transform.Translate (-Vector3.forward * moveSpeed * Time.deltaTime);
        }

        if (Input.GetKey (KeyCode.LeftArrow)) {
            transform.Rotate (Vector3.up, -turnSpeed * Time.deltaTime);
        }

        if (Input.GetKey (KeyCode.RightArrow)) {
            transform.Rotate (Vector3.up, turnSpeed * Time.deltaTime);
        }

I want to make something like a smiley face or just put a different color on the “face” of the cube so that the players will know what direction they are facing when the game starts…

I don’t know how to do that… I was thinking to create a material and modify it and then apply it to my player cube… but I don’t know how to do that either… I have just started in unity and I have previous experience in scripting.

I already saw these:

However, the most interesting answer is this:

Yup. Unity’s default cube is shared UV between all faces.
Just learn the basic of 3D modeling and UV unwrapping should do this job nicely.
Then paint the texture you want in Photoshop or similar painting tools.
I assume you are pure programmer. I always suggest people to learn other aspect of knowledge.
Because this will improve your overall planning which make game development more easier.:wink:
