Hey everyone! :smiley:

I apologize for not updating this list recently, as I’ve been quite busy lately. However, I wanted to share a small Aseprite script I just finished working on. It allows you to import images from a folder into new layers.

You can find the script here: https://bitbucket.org/jjhaggar/aseprite-scripts/src/master/import_images_as_layers/

Feel free to give it a try and let me know if you have any feedback or suggestions. Enjoy! ^^/

Hi JJ, this script is exactly what I’ve been looking for. Tho I can’t seem to run it, it keeps giving me this error:
image_2023-08-29_222405188
“Unexpected symbol near ‘<’”

Thank you for making this btw :))

I suspect that the problem is that you downloaded the file as “html”, and not as “lua”.

Please, try downloading it from here: Bitbucket
Click that link > Click on the 3 points at the top right > right click on “open raw” > save link as “import_images_as_layers.lua”

If it still doesn’t work, please create a .lua file (you can use notepad++ for example) and paste this code inside:

    label = "Instructions: ",
    text = "Select an image in the folder that contains all the images you want to add as layers"
}
dlg:file{
  id = "file",
  label = "File:",
  open = true,
  save = false,
  onchange = function(file) dlg:modify{id="file", text=file} end
}
dlg:button{ id = "ok", text = "OK" }
dlg:show()

-- Extracts the directory path of the selected file
local file = dlg.data.file
local dir = app.fs.filePath(file)

-- Gets a list of files in the selected directory
if app.fs.isDirectory(dir) then
    local files = app.fs.listFiles(dir)
    for _,filename in ipairs(files) do
        -- Check if the file is an image by its extension
        local extension = string.sub(filename, -4)
        if extension == ".png" or extension == ".jpg" or extension == ".bmp" or extension == ".gif" then
            -- Extract the full path to the file
            local filePath = app.fs.joinPath(dir, filename)

            -- Check if there is an active sprite
            local sprite = app.activeSprite
            if not sprite then
                return app.alert("There is no active sprite.")
            end

            -- Creates a new layer with the file name
            local newLayer = sprite:newLayer()
            newLayer.name = filename

            -- Load the image
            local image = Image{ fromFile=filePath }

            -- If the image could be loaded, add it to the sprite
            if image then
                -- Get the current frame
                local currentFrame = app.activeFrame

                -- Adds the image to the layer at the current frame
                sprite:newCel(newLayer, currentFrame, image)
            else
                app.alert("Could not load image: " .. filename)
            end

            -- Refreshes the sprite view
            app.refresh()
        end
    end
else
    print("Error. Select an image in the folder you have all the images.")
end

And please let me know if it works :slight_smile:

Script for editing XML atlases for Towerfall. I know it is only useful for a few people, but the code could be helpful to look at.

Hope you like it! if you have any suggestions please tell me.

Hi emscape,

thanks so much for this script!

I was dealing with my own exporter and couldn’t get aseprite to only save specific frames with SaveFileCopyAs. Your way works perfectly! Thanks again so much, this is a huge bugbear of mine dealt with :sweat_smile:!

Happy that it suits your needs!

Edit: forgot to mention exporting tiles also splits frames :slight_smile:

I’m new at scripting for aseprite, i wanna something to select some blocks of 32x32 in the canvas, then flip it and move it one pixel for right or left.
i Found this to move


app.command.MoveMask{
  target='content',
  direction='right',
  units='pixel',
  quantity=1,
  wrap=true
}

and about flip i got this

app.command.Flip{
}

its good, but now i need something to select the location before move it.

Hi all, I’ve been at it again. Made a script to create a Paint Drip animation.
Here you can download it for free.

If there’s animo I can make it support masks and have some layer options as well as optimization

I’ve made s script to emphasise the layer you’re working on so you’re able to see better what you’re doing. There’s a free download for all patreon members (including the free ones) so please sign up for free:slight_smile:

I made a script for isometric “tiled mode”. It clones the selection to see how the texture fits. I hope it Helps! You can download the files at github.

Hi @JJHaggar - feel free to add my latest script to the list :slight_smile: There’s a post about it here.

Palettize (by @Projectitis) Gives you finer control when applying a fixed palette to an image, including tweaking HSV of separate channels, excluding specific color matches, and a preview before applying.

Hi, again, Aseprite buddies! :smiley:

I finally updated the first post, with lots of scripts (and since I only added the ones posted on this list, I’m sure I missed several ones XD)

These are the new ones I added to the first post (on 2024-04-18)

I don’t have much free time, and this post is getting hard to maintain ^_^U Maybe it would be a better idea to create a Github repo for this list? That way, anybody could help updating it! What do you think? ^^

Great idea!

If no-one beats me to it I will create a markdown page of your initial post and submit it to the official aseprite “script examples” repo this weekend.

A markdown library of community scripts that Ives in the official repo would be awesome. If the authors agree :slight_smile:

What do you think!

Aseprite is working on an official scripts and extensions database with some amazing functionality.

In the meantime I have copied the scripts to an “unofficial” community scripts collection repo. Like @JJHaggar, I don’t have tons of free time, but it will be easier to manage a list this way. When the official database is ready, the scripts can be moved there instead.

Scripts can be submitted to this list by filling in an issue form: Submit a script.
