Aim trainer

My goal is to make an aim trainer game. As an example, I leave a site link, you can check from there what I want to do.
If there is an example core game game, I would appreciate it if you could write the link or its name.

Sorry I'm not clicking on an external link from someone with no posting history, can you describe in some detail what it is you wish to achieve in Core, what you've tried and what the specific scripting problem is? If you just want to make a shooting range with various weapon parameters then it would be good to check out some of the tutorials, e.g. Weapons Tutorial
