Game Development How to Make a Video Game Score, Enemies, and Game State Script the Score Counter

Frames per second

Hi all, So I just used the example of adding the Score text field to to the frog game to make a Frames per second Text field on the same canvas.

Here's the code:

public class FrameAverage : MonoBehaviour {

    private float frames;
    private int loops;
    private int oneSecond;
    private Text textBox;
    private bool logFrames;

    // Use this for initialization
    void Start () {
        frames = 0f;
        loops = 0;
        oneSecond = 1;
        textBox = GetComponent<Text> ();

    // Update is called once per frame
    void Update () {
        // Check if Logging:
        if (logFrames) {
            // Log average fps for last 10 frames to the screen:
            if (loops == 10) {
                frames /= 10f;
                textBox.text = "Frames: " + frames;
                frames = 0f;
                loops = 0;
            } else {
                frames += oneSecond / Time.deltaTime;
        } else {
            // If logging unchecked, clear screen:
            textBox.text = "";


My question is: When I run this, I get frame rates of about 18. Now the laptop I study on is in no way powerful at all - built in intel graphics, 8GB RAM, ultrabook i5 CPU, but it can still play lots of 5 year old games at well over 50fps lol, and this is a pretty basic scene with not a lot of things to draw so that made me wonder:

  • Is my script wrong - I'm getting fps by dividing 1 second by the time the last frame took?
  • Is Unity just quite slow when you want to play-test your game?
  • Is something in this scene more demanding than I assume it is?

Thanks in advance for any help or clarification :)
