Sanscript

Sanscript is a programming language designed for the Sans-themed fangames of the indie horror game Undertale. It allows players to create and customize their own Sans-based battles within the game's engine. The language is relatively simple and focuses on defining attack patterns, character behavior, and dialogue sequences. Its primary purpose is to enable user-generated content and extend the replayability of existing fan-made games.

The syntax of Sanscript is inspired by scripting languages commonly used in game development, with a focus on readability and ease of use for those with limited programming experience. It utilizes a command-based structure to specify actions such as spawning projectiles, altering character sprites, and triggering sound effects. Variables can be used to manage game state, such as player health or attack cooldowns.

Sanscript is not a standalone language but rather an embedded scripting system within specific Undertale fangames that support it. This means that Sanscript code is written and executed within the context of these games. Its development and adoption are driven by the Undertale fan community, fostering a collaborative environment for sharing and improving custom battle scripts. The flexibility of Sanscript has led to a wide variety of creative and challenging fan-made battles, showcasing the community's ingenuity.
