RWEditor

A rain world level editor remade from the ground up with javascript and html/css. link to my editor: https://rweditor.net

to do things

• click left mouse to use the currently selected tool
• click and hold middle mouse to move the view
• to erase, select the "air" geometry type and draw with it

material format

in materials.json

{
  "materialName" : {                          //the only requirement for the material name is that it's different from every other name in the json file
    "baseSize" : 20,                          //the base size of each asset in pixels. this is used to split the big textures you make into a bunch of small ones i can use
    "type" : "tile",                          //the type of the material. see below for all supported material types
    "variants" : 2,                           //the number of unique versions of the same tile. in the editor you can choose a specific variant or a random one
    "includedTileTypes" : {                   //tells the editor which types of tile this material contains. if its not here it will take the default material's tiles instead
      "wall" : [2, 2, 2, 2, 2, 2, 2, 2, 2, 2],//the layout for each layer of that specific tiletype of the material. a tile is always made of 10 layers. see below for what each number means in this
    }  	
  }
}

layers

• each number represents which texture to use for that layer of the material
• 2 textures are provided to every material by default. texture 0 is just an invisible texture to be used as padding, and texture 1 is a green texture in the shape of the tiletype you've selected
• every texture after 1 (so 2 to infinity) are textures that you added manually to the material
• the main geometry types are : wall, slope, semisolid platform, pole, and cross pole. to edit the layer setup for them just add an entry to the includedTileTypes list with your desired layer setup

material types

{TODO: a more complete tutorial on material creation}

tile

• a simple tile that doesn't care about any of its neighbors

simpleConnected

• a tile which will care about its four directly adjacent neighbors and connect with them. make sure to lay out the textures properly using the provided templates
• to add more layers, just duplicate this texture downwards with whatever variations you want for that other layer, and importantly there must be a 1 pixel gap between all individual textures

complexConnected

• a tile which will care about all 8 neighboring tiles. again make sure to lay out the texture correctly using the correct template below
• the method to add more layers to this is the same as above
  

mask

• (not currently implemented) uses green areas of the baseMaterial material to act as an area to "allow" a desired texture to show through

random

• (not currently implemented) a tile which will place down randomized sprites taken from a big texture, roughly within the area of the tile the material was added to
