Everhorn newlestehorn is a map editor for the newleste.p8 project. It's a newleste.p8-specific version of Everhorn with UI improvements and all-new Camera Trigger support by @gonengazit!
Carts from the newleste.p8 repository have already been setup for you, this is just for your information:
Everhorn is a room-based editor, like Ahorn. While it is able to open and save vanilla Celeste carts, splitting them into 16x16 rooms, its true power is revealed when using Evercore, which is able to load maps from variables levels and mapdata, located in the second code tab. To get started with an evercore-based cart, you need to open up the code in it, find the place where levels and mapdata are defined and surround them in --@begin and --@end comments like this:
--@begin
levels={
...
}
mapdata={
...
}
...
--@endEverhorn will now be able to locate this section ('Everhorn section') and automatically read levels and mapdata from it and write them back. Note that you can create as many rooms as you want, however, Evercore will actually load them into the normal PICO-8 map the moment you enter them. This means that you must place rooms within the boundaries of the map (shown as a grid), or you'll get fucky stuff (nothing permanent though, don't worry). However, you can simply stack rooms on top of each other and it will work fine.
Newlestehorn 1.1 introduced an additional @conf block that will be added automatically before @begin; this block contains commented code (not visible to the running cart) that newlestehorn uses to store project settings, such as autotile tilesets and room parameter names.
Go to the Releases section at the top of the page.
- Ctrl+O - Open a .p8 cart file (loads rooms and the spritesheet).
- Ctrl+S, Ctrl+Shift+S - Save/Save As.
- Ctrl+R - reload the spritesheet from the currently opened cart.
- Ctrl+Z, Ctrl+Shift+Z - Undo/Redo. Can undo pretty much anything (including something like deleting a room).
- Middle click or Shift+Left click pans camera, Scroll zooms in/out.
- Shift + Right Click selects a tile from the map
- N - create new room.
- Alt+Left/Right Mouse Button - move and resize rooms.
- Up/Down, Ctrl+Up/Down - switch between rooms and reorder them (can also click to switch).
- Shift+Delete - delete room.
- Ctrl+Shift+C - copy the entire room (it's text-based, so you can send it to someone directly).
- Space shows/hides the tool panel with the tools and the tileset. The tileset also includes 3 autotiles, which will automatically pick the right version of the tile based on it's neighbors, both when drawing and erasing. They are defined to match vanilla snow, ice, and dirt (you can put any other sprites instead, of course, and I can define more if needed).
-
- Brush - left click to paint with the tile, right click to erase (tile 0)
-
- Rectangle - same but in rectangles.
-
- Select - basic selection tool, click and drag to select a rectangle, then you can move it, place it, copy or cut it with Ctrl+C, Ctrl+X and paste with Ctrl+V.
-
- Camera Trigger - tool for adding, moving and resizing n.p8 camera triggers. Use Ctrl+Left/Right Mouse Button to move/resize.
-
- Room - currently allows setting room exits and whether the room is stored in code inside a string, or in mapdata.
-
- Project - allows adding/removing level parameters, and configuring whether string levels are saved in base256 or hex format (defaults to whichever the cart uses, or base256 if the cart has no string levels)
- Tab toggles playtesting mode. When it's enabled, saving a cart will also inject a line of code that spawns you right in the current room and disables music. (conveniently, in PICO-8 you can press Ctrl+R to restart the cart and it will reload the map as well!). Press Tab again to enable 2 dashes.
- CTRL+H - shows/hides garbage tiles on the tool panel
- CTRL+T - shows/hides camera triggers when not using the dedicated tool
- 1, 2, 3, 4, 5 - switch to the nth tool
