I'm making an engine for the vines in the Photoshop Flowey fight. It involves creating a bunch of clones and launching them towards the player, leaving a pen trail. The trail is then supposed to disappear. I used the

clear

block to delete the trail, but it also deletes the trails of other clones. How do I delete the pen trail for ONE sprite?

There isn't a way to erase the strokes from just one sprite or clone, there is only one pen layer that everything draws to. Either you would have to draw over the previous stokes to match the background (or whatever was there before the stroke was made) or erase everything and redraw it (which is simpler and more common). It highly depends on what you are doing.

I see. I recomend that you use lists to store the trail information of all sprites. Then after you erase all, then you can draw them back using the list.

Don’t use pen trails, use clones of clones

I would try to add and delete clones. Might not work, but its worth a shot!

create clone of [ v]
when I start as a clone
delete this clone

The clear block will clear every pen trail, and i dont know of a work around

BUT, if you use sprite trails instead, it may work better.

I think grifpatch made a video about it lol

ALSO - THIS MY 100th POST!!!!!!

I would say that you should just somehow store the trails with lists, and make a custom block that reads them and put the block in the clones so when you erase all, you just redraw

add [trail] to [trail list v]

when I receive [erase v]

clear

read trail list

define read trail list
