FS_file_exists

[Minegamezz]

Hey guys,
I'm really new to the community and wanted to give game development a try.
I got all the stuff from this forumpost https://iwannacommunity.com/forum/index.php?topic=1625.0 and imported all of it in game maker studio.
I've built a little level, but when i try to run it, these errors appear https://puu.sh/z8X0B/fefdd0eaf7.png

Help would be much appreciated

FS_file functions are from a GameMaker:Studio extension that not a lot of fangames use anymore. Klazen's engine just so happens to use it, and it appears that you're missing the extension, which is making gamemaker spit out those errors telling you it doesn't know what those FS_file functions mean.

When you followed Klazen's guide, you should've downloaded his project file. If you go to the extensions folder in the GMS_Engine_KS_Edition.gmx folder the file should be there. The file you're looking for is GMFileSystem.extension.gmx You can drag-and-drop that file into your project to add it, that should fix your problem.

Good luck making games!

First of all: Thank you very much for the quick reply!

That did solve the problem, but another one occured

It doesn't even tell me what the problem is now.

If this won't work, I guess I can just start from scratch with only the sprites?
