Hello megarcher,
I've tried to make the zoom script myself but I'm running into alot of "Input" errors. Would you be so kind to explain how you made the script (or paste the script itself)
If you're not familiar with the new unity input system, you might want to change support for the old input system in player settings. Then you can just make a script using the old input system. Don't forget to make the background bigger and change the input/output pins locations. (or the input pins will be halfway on the screen)
