ALttP makes common use of entrances with access rules that require another entrance to be accessible. This results in requiring an indirect condition to be registered for the other entrance's `.parent_region`, but this indirect condition is often missing. There are so many missing indirect conditions, and due to the complexity of some of the chained rules, it is simply not realistic to add all the missing indirect conditions. This patch changes ALttP to use automatic indirect conditions instead of explicit indirect conditions and removes the places that were registering indirect conditions. Without this patch, the missing indirect conditions almost never have an effect on generating with default options, but enabling certain options, such as `glitches_required` or `entrance_shuffle` can result in frequently checking entrances that are missing indirect conditions. Examples of complex chained rules: `get_rule_to_add()` in `Rules.set_bunny_rules()` can create rules on entrances that require access to any of a number of different other entrances, which should require the parent regions of all of those other entrances to be registered as indirect conditions. There are entrance access rules that check `StateHelpers.can_kill_most_things()` (e.g. `Turtle Rock Second Section Bomb Wall`), which can check `can_extend_magic()`, which checks for being able to buy unlimited `Blue Potion`, which checks for being able to reach a shop that sells unlimited `Blue Potion`. This is usually `Potion Shop`, but there is a yaml option that shuffles shop inventories, so the shop that sells unlimited `Blue Potion` can be randomized, meaning that the region that should be registered as an indirect condition can also be randomized. Example of many missing indirect conditions: With `small_key_shuffle: universal`, every single `ALttPLogic._lttp_has_key()` checks for being able to reach shops that sell an unlimited number of universal Small Keys. Meaning that every entrance access rule that uses `_lttp_has_key()` should register all shop regions that sell unlimited universal small keys as indirect conditions.

History
Archipelago is built upon a strong legacy of brilliant hobbyists. We want to honor that legacy by showing it here. The repositories which Archipelago is built upon, inspired by, or otherwise owes its gratitude to are:
- bonta0's MultiWorld
- AmazingAmpharos' Entrance Randomizer
- VT Web Randomizer
- Dessyreqt's alttprandomizer
- Zarby89's and sosuke3's contributions to Enemizer, which make up the vast majority of Enemizer contributions.
We recognize that there is a strong community of incredibly smart people that have come before us and helped pave the path. Just because one person's name may be in a repository title does not mean that only one person made that project happen. We can't hope to perfectly cover every single contribution that lead up to Archipelago, but we hope to honor them fairly.
Path to the Archipelago
Archipelago was directly forked from bonta0's multiworld_31 branch of ALttPEntranceRandomizer (this project has a
long legacy of its own, please check it out linked above) on January 12, 2020. The repository was then named to
MultiWorld-Utilities to better encompass its intended function. As Archipelago matured, then known as
"Berserker's MultiWorld" by some, we found it necessary to transform our repository into a root level repository
(as opposed to a 'forked repo') and change the name (which came later) to better reflect our project.
Running Archipelago
For most people, all you need to do is head over to the releases page, then download and run the appropriate installer, or AppImage for Linux-based systems.
If you are a developer or are running on a platform with no compiled releases available, please see our doc on running Archipelago from source.
Related Repositories
This project makes use of multiple other projects. We wouldn't be here without these other repositories and the contributions of their developers, past and present.
