player speed

[paupav]

Ok, I wanna create simple snake game, and I'm stuck.
And I've wanted to ask you how do you create variable that defines player's speed.
E.g I wanna make my snake moves 15 blocks every second. Do you use clock somehow?

This is how I did it before, but that's messy way of doing that:

The answer to your question can be found in every basic physics textbook. Speed is distance travelled per unit time.
And yes, you would use a clock to keep track of time passed.

Edit: I recently made a simple example of a bouncing ball. Take a look - maybe it'll help you
