As soon as the sleep screen starts, the mod starts searching for the necessary files with the extension ".json" in the mods folder. Then the mod tries to find the same files in the sprite folder of this sleeping slugcat. And if the mod finds them, then it will use new ones.

For example, I will use The Slopeyed (SaltCat) mod made by Saltfornow.

Just in case, I'll point out that the mods from the workshop for rain world are located in the steam folder along the following path : \steamapps\workshop\content\312520

Opens the folder with the custom slugcat mod and go to "scenes" and then look for the folder where the sprites for sleepscreen are stored.

Next, we create the "entitiesinden" folder and open it.

Now we need to copy the json file we need and paste it into the folder we created.

To do this, follow this path in the steam folder : \steamapps\workshop\content\312520\3496047692\entitiesinden
and copy and paste what we need.
I chose Vulture Mask.



Now we need to go into the json we copied.
We see several properties here, but for the most part, we just need to change the position of the sprite.
First, we need to delete the variables "whi","yel","red", "gou","art","riv","spe", "sai".(They don't affect anything here).
And then find the "pos" variable. It is responsible for the position of the sprite.
Changes the values of x and y in the "pos" variable and saves the changes.


Default

Edited

To do this, we create a text document in the created folder and name it "slugcatIndex".
In it, we sort of indicate the number under which the slugcat sprite was uploaded. If you don't know how the slugcat sprite is loaded, you can simply iterate through the numbers from 0 to the number of sprites in this folder - 1.
