Cave Story Tilesets and Tile Properties

If you want to make your own, make sure that:

  • It is saved in .bmp format
  • Begins with the letters “Prt,” such as PrtCave, PrtWeed, etc
  • Tiles are 16 pixels by 16 pixels each
  • Has a maximum height of 256 pixels and a maximum width of 256 pixels

Once you have made a tileset, you will have to assign properties to each tile. [In Cave Editor,] click on a tileset and press the “edit tileset” button. This can also be achieved by right-clicking the tileset and clicking on “edit tileset.”

Now, there are distinct properties for most tiles, but most function identically. Here’s a list going over the major ones that are always used by Pixel:

  • 0- Air. Nothing. Nothing will be rendered if you put anything in there.
  • 40- Used for decorations such as grass, small stones on the ground, and more importantly, fake blocks. Will be rendered in front of the PC
  • 41- Solid blocks. The Player cannot get through any of these, if you didn’t know what a solid area is.
  • 42- Spikes. Note that the same tile property is used on several spikes facing different directions. Why? There is a 4x4 hitbox in the center of the area, and will damage the player when it touches it. Also, this will render in front of the player.
  • 43- Breakable blocks. Also known as those “Sn” blocks in some of Pixel’s tilesets. If you want to edit the appearance for the breakable blocks, go to NpcSym.
  • 44- No NPC blocks. Monsters and other NPCs will not pass through. A great example would be the vines in Grasstown/Bushlands.
  • 46- Not really used by Pixel, but the Player cannot pass through this. Same effect as any solid object.
  • 50-57- Diagonals. Not much to say about those.
  • 60- Water. The stuff that will make you drown if you stay in there for too long.
  • 62- Spikes!... In Water!
  • 70-77- Same as tile tiles 50-57, but have water
  • 80-83- Eternal Winds. Will move the player in the direction of the arrow.
    • 80- Left
    • 81- Up
    • 82- Right
    • 83- Down
  • A0-A3- Same as tiles 80-83, but in water. Very commonly used in the Waterway.
    • A0- Left
    • A1- Up
    • 82- Right
    • 83- Down
