Whenever i press F5 or Play on the Desktop version, the engine crashes with the error "The program has stopped working", how can i fix this?

Don't panic, this is likely just some errors in your game code (such as an endless loop) and thus why quest crashes, that needs to be fixed up.

If you right click on your game file, and open up it up with a text software (notepad, wordpad, notepad++, Apple: text editor, etc), you get into the (entire) game code. Just highlight all of it and copy it, then paste it here, either: publically as a post here on this forum or privately send it as an email attachment (or put it on a GitHub account --- read the guide on how to do so if you're new to GitHub) to one of the site mods and/or a user you can trust, who'll look over your game code, and fix it up.

P.S.

if/when you paste/write code in your posts, use this to put it into the code box:

.```
your pasted code
.```

but without the dots/periods in front of the 3 symbols/characters (this is the keyboard key to the left of the '#1' key at the top of your keyboard as a row --- not the '#1' key on the right side of some keyboards arranged in the square/old phone block)

it'll look like this:

your pasted code here

Sorry for hijacking the thread a bit, but hegemon, how do we send private anything anymore? As far as I've seen there's no way to contact anyone through their profiles since the forum overhaul.

my previous post states how: by email or via GitHub.

I do miss the features of the old forum such as PMs and being able to search a user's posts (I had to use google search to find my 'HK noobie help me thread' Thread in response to trying to help someone and/or to show them how I struggled when I was first learning quest and programming 4 years ago). Email and GitHub are a bit longer/greater efforts than they're worth it, for just merely posting code. Though I do understand 'feature creep', Alex can only do so much at a time, and we've got a gazillion things we can ask him to implement. Though, in my opinion, some of the missing features were useful for us users...

There is a search the forum box at the very bottom of the thread posts.
