Event functions

This PR's missing /reference/Event_Source_Element because I don't have any idea how to make it.

It’s great that you want to help develop the wiki! But you need to know that the old, original wiki isn’t perfect - very often it’s incomplete and contains incorrect or outdated information. That’s why please always verify the description and syntax against the source code. While creating many functions, I very often came across outdated descriptions, incorrect examples (for example with typos), missing OOP documentation even though the function supports OOP, and a lot of mess left after the scraping process.

So this is my personal request: verify and edit the content, don’t trust the original wiki blindly, and don’t just copy information from it.

Thanks for your review! I was just copying from original wiki to here I didn' know the original has many mistakes btw I'll fix them

Thanks! The Lua code formatting still isn’t correct, but I’ll fix it and you’ll know for the future what I meant.
