Determining the rotation of an object based on its upcoming position?

[UserUnityAriel]

Hi,

I have an object that I would like to rotate so that it’s “head” (one end of the rectangle. I want to be able to apply this to any object though) is facing the direction that it is moving in. I don’t have a target that I want to look at so the object needs to be able to know it’s correct rotation based on it’s upcoming movements. See the following picture for an example :

My idea was to find the inverse of tan of the opposite and adjacent values ( ie x and y ) and then to convert those radians to the new rotation angle. However, this doesn’t seem to give me the desired result?

Here is the code that I’m using:

        float z = Mathf.Rad2Deg * Mathf.Atan(x / y);

        GetComponent<Rigidbody>().rotation = Quaternion.Euler(0,0, z);

My object is moving in small increments vertically and horizontally based on the 2D plane every frame so I was thinking of doing something like so to make it seem like a more realistic rotation but it’s also not giving me the result that I’m looking for. What would you recommend?

     float inc = Mathf.Rad2Deg * Mathf.Atan(x / y);

        if(inc > 0) { 
        for(int i = 0; i < inc; i++) {
            z = i;
            GetComponent<Rigidbody>().rotation = Quaternion.Euler(0,0, z);
        }
        }
        else
        {
            for (int i = 0; i > inc; i--) {
            z = i;
            GetComponent<Rigidbody>().rotation = Quaternion.Euler(0,0, z);
        }

Something along the lines of setting the rotation euler angles to the rigidbody’s velocity vector, can’t remember. Good thing I can point you to a script that does exactly that!

smooth follow C#

It does have damping, but the whole principle is in there.
