How can I make a custom line brush that can be used with a curve?

Help

Hello everyone,

Apologies, I am a giant newbie and do not really know what I am doing. I understand that oft times forums like these are for more experienced people, but I have tried to find a solution online and couldn’t. So here is the context:

I am creating a game that has a map similar to the one in inscryption in that there will be stages / levels connected by a dotted line. However, unlike inscryption - I would like to add some curvature to my lines to make them pop a bit more - aesthetically speaking.

I have been reading up and have managed to create a custom brush with ctrl B, but am struggling to figure out how to let the brush rotate and work as I desire with the curved line tool.

Here is the image I am using for my custom brush: I put it on a 64 by 64 canvas.

Apologies again for my newbiness. I promise I am trying my best, I simply have no idea where to look to find this information. I have been looking at videos on custom brushes but haven’t found one that answers how to do this. Is this even possible?

Best wishes,

yjzhou

I don’t think that this feature is in Aseprite. It’s more commonly available in vector graphics than raster graphics programs. For example, you might want to try Inkscape’s pattern along path effect instead

Then export the vector artwork to a raster image.

You could try using the Aseprite Lua scripting API to create the feature, but I’m afraid it’s not really a newbie friendly problem. A thorough background with the maths of cubic Bezier curves is needed – something I don’t have myself.

For anyone interested, Pomax’s primer is a solid resource on the topic. I’m linking specifically to the section on tracing a curve at fixed intervals, but there’s a section on calculating arc length as well.
