How to move object by "steps" controlling time?

Hi, I'm beggining with Unity and I have a problem with my project. I guess it must be a very stupid question but I havent found anything in the web and don't know what else I can try. I'll just paste the necessary code:

Code (CSharp):

1.     void walk() {
2.         Vector3 plpos = player.transform.position;
3.         plpos.z += 1;
4.         player.transform.position = plpos;
5.     }

I have a surface that I'm using like a kind of chessboard. What I want is to move the player from cell to cell but not describing a linear trajectory. I just want it to appear in the next cell. The code I've pasted works, but now is when my problem appears. I want to call this function in void update(), but of course the player disappears in a blink. I've tried to use Time.deltatime in multiple ways, but the problem is that as I said, I don't want a linear trajectory, I just want that each second the player appears in the next cell and I don't know if deltatime is what I need.

 

You can structure your Start() function as a coroutine and have it call walk() periodically , like so:

Code (csharp):

1. IEnumerator Start()
2. {
3.     float interval = 1.0f;    // how often to step
4.     while( true)    // endless loop
5.     {
6.         // wait for an interval...
7.         yield return new WaitForSeconds(interval);
8.         walk();        // take one step
9.     }
10. }

Make sure you do NOT take out the yield statement or else Unity will lock up with the abovecode.

 

Thank you! works perfectly! I suspected this is what i needed, but I didn't know how to apply it to my case.
