WorldD - level designer for pygame

W - brush tool (default)
X - rect fill tool
E - reset tile to nothing (eraser)
SHIFT + X - rect autotile fill tool
Up and Down arrows - scaling size of the tile,
CTRL + DELETE - delete tile from lookup (all occurrences of tile will be deleted),

by renaming the tiles in the lookup, every tile in the grid will be replaced.
CTRL + T - toggle tile mode

tile mode is when you want to add new tiles or delete them
ALT + E - export tiles

classically you have two inputs, one for the tile group name and one for the tile name.

export feature will make so it will generate tiles from starting point to the end selection with each tiles having the selected tile size.

for example, you will start at 0x0 and end at 0x64 with the tile size being (32, 32) and name of the tile being "tiles":

you will have tiles:

(0, 0, 32, 32) - "tiles - 0x0",

(0, 32, 32, 32) - "tiles - 1x0",

(0, 64, 32,32) - "tiles - 2x0"
CTRL + E - edit tile

when editing tiles they aren't replaced, they make a new copy. making it replace could break the entire map, since the map is "indexed", that means each tile is a reference for a tile group and a tile in it.
< or > - toggle between editting group name and tile name

right arrow - new layer / change selection to the layer above
left arrow - change selection to the layer below, you can't select layers below 0.
CTRL + R - rename layer
SHIFT + DELETE - deletes current layer

path of the image is absolute. If you want to use WorldD you have to change the path to be relative, otherwise there is a very high probability it will not work.
