The Character Editor - SlightlySimple/FNF-Restructure-Engine GitHub Wiki
The character editor allows you to create new characters or edit existing ones in Restructure Engine. It can be accessed from the Editors Menu, which by default is accessed by pressing "E" on the Main Menu.
Creating a new character
By clicking on the "Character Editor" text, you will be brought to the Character Editor. Once there, you can click on "File" and then "New" to bring up a file selector where you can select a sprite sheet for your character.
Sprite sheets go in the "images" folder of a mod, or any folders inside of it. By default, your mod should have a "characters" folder in the images folder, or in a subfolder of the images folder. This is where you will want to place your sprite sheet.
If your sprite sheet has a PNG and an XML file, they both go in the same folder. If your sprite sheet has a PNG and a TXT file, they both go in the same folder. Your sprite sheet may also have only a PNG file.
Once you have selected a sprite sheet, it will be loaded the editor. By default, it will attempt to create an "idle" animation for your character based on the most fitting animation prefix in it's sprite sheet.
Saving
In the previously mentioned "File" menu is a "Save" button. Clicking this will bring up a file selector which lets you decide where to save the character. The character should be saved in the "characters" folder inside the "data" folder of a mod, or in a subfolder of that "characters" folder.
Once you have saved your character at least once, pressing "Save" again will save the character with the same filename you already gave it. You can also do this by holding Ctrl and pressing S on your keyboard.
Additional Info
The Character Editor has a help screen that can be accessed through the "File" menu or by pressing F1 on your keyboard. Additionally, every option in the Character Editor will give you an explanation of what it means/does if you hover over it.
