Repixture/DEVELOPERS.md

Developer information

This file explains information to document the code of Repixture and information for people wanting to develop or mod Repixture.

Note the focus of Repixture is not to be a "base for modding", but to be a standalone game in its own right. That having said, Repixture also doesn't actively oppose modding.

Core development

Testing

There are some hidden testing/debug settings. Add them into minetest.conf to activate:

• rp_testing_enable=true: Enables Testing Mode. Performs some simple benchmarks on startup (See the log file / console) and also enables testing the validity of crafting recipes, gold trades, and more (printing errors if any errors were found). This also enables a few helper chat commands (see /help).
• hunger_debug=true: Enables Hunger Debug. This displays the internal hunger values on the screen.

Some modding rules

• Crafting recipes (except cooking and fuel recipes) MUST be registered through rp_crafting.
• Modifying player physics (like running speed) MUST be done via rp_player_effects.
