Coin Magnet [Unnamed]
Coin Runners only
Editing KMPs to move coins (and maybe start positions) has in my eyes two disadvantages: First you have to waste time to find the correct configuration of where to put them, and second you will not be able to play normal games anymore, unless you find a way to toggle between custom track files.
This is a much easier way to do "coin KMP" now, with this code! Simply press your activator and you will attract the coins like a magnet. Of course, this is only working for free coins. Works offline and online.
NOTE: You mustn't press any other buttons when pressing your button(s) to make the code work.

## The Hook adress seems like to be in a function that loads the coordinates of objects and then do some calculations (no Idea what lol), we can use this adress for our code. ##
