How do I change sprite colour depending on touch speed

Hi everyone,

Could be a really simple question but it has me stumped.

I would like to change the colour of a sprite depending on how fast the user taps the screen.

For example:

no taps - white sprite

lots of taps - red sprite

I don't have a problem changing the colour of the sprite, but how can I measure the frequency of the users taps?

Thanks!

Do this:

System Event -> On every 0.5 seconds (for example) & Is Object being touched.

If it misses one it will stay white. Change the timing to get he frequency that you need.

Let me know if it works for you.

Cheers!

Hi henriquesv,

thanks for your advice - I just tried our your logic and it works - just not quite how I imagined it!

What I am looking for is a little more open ended. By that I mean instead of targeting a specific touch frequency, I would like the sprite to change colour gradually as the user taps faster and faster.

Any ideas?

Thanks again for helping out!

Try this capx. You also have to remember to check if touch has been released... otherwise the player would cheat =)

Hummm I see... let me think about it!

You could do this:

Set the timer to minimum period (increase frequency) and count how many touches it gets in a larger amount of time.

For instance:

Timer 1 (0.01s): check if the touch has been released and if it is touching. Add 1 to the counter.

Timer 2 (0.5s): check how many touches happened and set this number to a color scale; clear counter;

=)

Hi henriquesv,

thank you very much for your help, that looks perfect!

I will give that a try and let you know how I go (or if I need any more assistance =) .

thanks again!
