General requirements

all the software you need to make your own item.

If you are looking for the modding requirements (requirements to make a mod), head over the Mod Making section.

All you need for level and skin making is:

1. Jump King Worldsmith or a tool that converts images and sounds into XNB (in-depth details in the following category).

2. A simple pixel art editor or a image editor such as:

   • Aseprite (paid, open-source),
   • Krita (free, open-source),
   • GraphicsGale (free),
   • Adobe Photoshop (paid subscription),
   • GIMP (free, open-source),
   • paint.NET (free),
   • Procreate (iPad only) (paid)

   … or others that you might know of.

Nice to have

The following items are not required but nice to have for tinkering down the line.

• Basic knowledge on how to deal with files in Windows (cut, paste, copy, move and create files).

• And a text editor (that will be used for XML files) such as:
  • Visual Studio Code (free, open-source, recommended),
  • Notepad++ (free, open-source, recommended),
  • Notepad (preinstalled on Windows)

  … or others that you might know of.

• If you are making a level, SaveStates (checkpoint maker) or JumpKingManager can help out testing you level further by saving/loading your position.
