The art for characters, which includes their model and the poses that make up their sprites, is made in a 👍 Japanese paper doll program called Kisekae, which is based on the K-On anime art style and was developed by a 👍 user named Pochi. Kisekae has both an online and offline version; the offline version is the one used with other 👍 SPNatI character creation software to make sprites. Pochi continues to update Kisekae with new features to this day.
Many characters' sprites 👍 also utilize image editing and other forms of post-processing, such as Photoshop. Additionally, to save file space, character sprites are 👍 compressed using a web tool known as TinyPNG.
A character's dialogue, mechanics, metadata/information, and pose-to-line assignments are found in their "behaviour.xml" 👍 files, which are essentially text documents. Creating a .xml file can be done by using the SPNatI Character Editor program 👍 ("CE") to write dialogue. The CE also has built-in support for converting Kisekae scenes ("codes") into character sprites, which would 👍 otherwise have to be done manually.
SPNatI offers comprehesive documentation on our tools, features, and policy in our Official Docs Repo. 👍 We highly recommend any new devs start here:
