Loop Draw is an extension for Aseprite that allows you to draw on the canvas while the timeline is playing! This idea had come from a discussion including Gizmo199and JJHaggar on the Aseprite community forums.

They were looking for a feature that would be much similar to one that is included in Game Maker Studio's sprite editor.

Being able to draw on the canvas while it's looping though the current timeline can lead to some very interesting animations.

This tool even works with custom brushes (select area and press control b)

This tool also works with different ink modes as well such as alpha lock!

Try different tools and modes to see what might happen. 

Recommended to try this tool in an empty project or new layer so you can easilly erase any unwanted pixels 😄 

Getting Started / How to use:

1. Open Loop Draw from the top menu Frame>Loop Draw..
2. Add in some blank frames (Ctrl B) if you only have a single frame.
3. Toggle "Is Looping" to start looping the playback.
4. To draw simply toggle or press the hotkey you've set for  the "Is drawing".  Found under Edit>Keyboard Shortcuts (Look for Toggle Drawing)
5. Move the mouse over the canvas (Don't click! Just move!) 
6. Smile because your about to have lots of fun 😆 

----------------------------------------
Please Note A Slight Limitation: 

Due to a slight limitation (not being able to detect left click with the tool) a hotkey for drawing can be set in the keyboard shortcuts menu. Edit>Keyboard Shortcuts. Use this hotkey to toggle drawing on the canvas.

The box on the dialog also will enable and disable drawing as well.

-------------------------------

A fun example could be  leaves blowing in the wind. Creating this flowing motion with your mouse and directing  the leaves where to flow. This even works with custom brushes and ink modes (like alpha lock!)

There are many more uses that the tool could be used for though the term fluid or flowing seems to come to mind when ever I use it. Anything that might fall in that category should be fun to create with this tool!

Loop Draw could also be use to get a rough idea on the canvas and then you can go back each frame and refine how the pixels might look. The leaf example would be good here perhaps you want your leaves to well look like leaves. You could start with a rough outline then refine afterwards!

However you might use the tool there is really no wrong way to use it! I honestly can not wait to see what you all come up with. Feel free to share gifs or videos in the comment section below! Looking forward to seeing what yall come up with!!

New hotkeys that can be set!

New option to add frames (extend) while drawing!

New In v 1.2.0:

Growing Brush

• Growing brush will either grow the current brush size when using a positive number or reduce the current brush size when using a negative number.

• Setting a min and max size will limit the brush size to not go below the minimum or above the max size set.

Color Change

• This new option will use a selection of preselected colors, changing to the next color every x frames that is set in the input box.

Growing Cels

• By selecting a range of cels and clicking Create Grow Cels LoopDraw will progressively merge the cels together to make a growing like animation.
• This is quite useful for growing vines, creating a delay, motion blur, writing text and much more!
• Try it after using a custom brush to get some awesome effects.

Looping Tag

• When enabled LoopDraw will enter the next tag and continue to loop in this tag until disabled.
• Keyboard Shortcut: Loop Draw Toggle Loop Active Tag

Stop At End 

• When enabled LoopDraw will stop both looping and drawing when the timeline reaches the last frame

• Useful if you would like to only play though your frames once and not overwrite your previously drawn frames.
• Keyboard Shortcut: Loop Draw Toggle Stop At End

Append Last Frame

• When enabled LoopDraw will continue to add frames once it reaches the last frame in the timeline.
• Keyboard Shortcut: Loop Draw Toggle Append Last Frame
