Hi

How to make a simple count from 0 to 5. ? when i press SPACE. 0 1 2 3 4 5 ?

Check out a for loop.

Or use more words to explain what you mean. Is there a Text on screen that should show the numbers 0 through 5, one at a time, 1 second apart? Or do you have six objects you need to assign a number to? Or one of the dozens of other scenarios that would fit your question?

The answers to these different scenarios will be quite different.

counting man. simple count. from 0 to 5. “0,1,2,3,4,5” count in seconds while I am pressing C.

int number = 0;

     if(Input.GetKeyDown(KeyCode.C))
        {
             // count number up
            if ( number >=5) {
                number = 5;
            }

            Debug.Log(" counting up " + number);
        }
        else {
            // count number down

            if ( number >=0) {
                number = 0;
            }
            Debug.Log(" counting down " + number);

        }

OK, I think you didn’t understand my point — there are many different ways and things to count. But you’ve now given enough clues to guess more or less what you mean anyway.

Here’s how I would do it.

  • Add a value field to your class. IMPORTANT: this must be a float.

  • In your Update method, use Input.GetKey (not Input.GetKeyDown) to check whether C is pressed.

  • If it is, add Time.deltaTime to your value.

  • Else, subtract Time.deltaTime from your value.

  • Display (somehow — I doubt Debug.Logs are what you really want) the value, truncated to an integer (for example, with Mathf.FloorToInt).

thank you Joe. its work now. here is my script:

    public float number = 0;
    void Update() {

        if(Input.GetKey(KeyCode.C))
        {
            number += Time.deltaTime;
            if ( number >=5) {
                number = 5;
            }

            Debug.Log(" counting up " + Mathf.FloorToInt(number));
        }
        else {
            number -= Time.deltaTime;

            if ( number <=0) {
                number = 0;
            }
            Debug.Log(" counting down " + Mathf.FloorToInt(number));

        }

    }

If there is anything can i add to improve the code please write it.
Thank you so much.

Looks reasonable to me.
