The Newbie Level Guide

This guide should cover level editing enough to get you started making your own levels

Overview

The Rundown currently out is Rundown 8, revision 34800. If you're reading afterwards, you may have to adjust. If we're lucky any future changes to level generation will be backwards compatible.

Be aware that game updates can break datablocks, and levels/rundowns usually suffer the most from this. Rundown developers often don't even port their rundowns after some updates.

There's now a page with finished blocks stored and updates noted located here.

If you get stuck or are unsure if some changes were made as updates passed, check it out.

As you probably already know, levels in GTFO are generated, and their data is stored in datablocks. In terms of difficulty, editing levels is between intermediate and one of the most advanced things in datablocks. This guide is not meant to teach all thing related to level editing, but it will hopefully give you enough to get you going in creating your own levels.

This goes without saying, but if you're looking to learn, I highly recommend editing and testing the blocks yourself as you read along.

Throughout the guide, I'll be posting datablocks or parts of them. If you move along, you won't have to copy-paste them, but you can verify they match using Diffchecker for example.
