How to make my character walk when I click a button?

Hello,

So I'm a bit new to programming and I want to make my character (a cube for now) to walk 1 unit per click on a button that will be on the screen. Also if possible how can I for example: if I press 2 times this button he jumps or if I press 2 times this button + 1 time other button he attack, etc. It will be a 2D game btw.



I didn't find the right solution from the internet.
