Angelscript
The majority of It Takes Two's gameplay is written in angelscript, a scripting language for Unreal Engine that is made by Hazelight. For more information about angelscript, please check out Hazelight's official documentation here.
The angelscript source code is located in your It Takes Two installation folder at ItTakesTwo\Nuts\Script.
The script folder is split up into a lot of smaller folders, each of them serving a different purpose in script, which I'll list here:
Cake systems are large gameplay sections that span longer amounts of time and involve a lot of systems to create coherent experience.
Editor only scripts
A folder containing example scripts and templates.
Peanuts systems are small, self-contained building blocks with strict specifications of behavior. These building blocks can then reliably be used to construct larger Vino and Cake systems.
Rice systems do not relate directly to gameplay or level design, but are still required to implement specific other systems.
Vino systems represent distinct gameplay moments that can used in levels or by larger Cake systems.
If you are using Angelscript mods, you'll likely see a Mods or Speed folder as well. These have been added by us for organizations sake.
