Making my first game issues

Here is a demo video of what I’m trying to do for an IOS game.


You click a number on the board and the number counts up. When it hits 5 it turns into 4 moving pieces. Those moving pieces might hit a object adding a 1 value to that object.

In the official documents for collisions it really goes into making real world collisions. I wasn’t able to find anything in there that about changing world physics. So I went searching physics by looking for ballon physics. Something that gets bigger with each reaction and eventually would pop. Kind of hit a wall with this. The worst part is I feel it’s a very easy answer and I’m not looking in the right part of the program.

My questions

  1. How do you make it so when an object is clicked it changes its value?
  2. How do make a collision recitation change its value?

Thanks!
