I want to draw with my pen, but it goes behind this sprite I've got. I don't want to get rid of the sprite. How can I put the pen on top? Putting the sprite it follows to the (front) layer doesn't work, and neither does putting the sprite that blocks it to the (back) layer.
A recent thread
Thanks. I don't suppose anything has changed since then?
Not as far as I know
Do you want to draw on a sprite instead of the stage (pentrails)?
If yes, i explored to solutions for you:
I decided to see if I can create a smooth system to draw on sprites like pe, and I've managed to do it.
This system modifies the movement primitives to draw on sprites whenever the sprite is moved. Not only that, this library also creates a sprite local variable to store a list of the sprites to draw on, so that each sprite can have their pen down on other sprites.
Now, the biggest limitation is that this only works like the flat line ends setting, so you can't make dots. This is because the block just creates a line costume then stamps onto the sprites, and it's super fast to create a rectangle.
P.S.
When I get kn my computer, I'll try to clean up the project, and also make a post for this.
Edit: I have made some changes, unfortunately snap was down at the time, so I'll have to upload the updated project later.
Blank project...
Heh, sorry, I guess I just didn't look at the link before sending it. I have now fixed the link.
Why do you need to hide it with code? You can do it from the hide blocks menu.
Because the sprite local variable that the library uses is created programmatically, which means that the variable will be shown by default. Also, I just figured out how to do it, but it looks like snap is down for me right now, so I can't update the project.
Your project has a bug in this block, and I have fixed it:
The trouble was that you were creating a 3-dimensional list when the "new costume" block expects a 2-dimensional one. The block would flat out fail with widths larger than 3, and did not take into account the colour at all.
Yeah, I actually just fixed that, but
Cool! How?
Yeah, looks like it. I tried clicking on the link to your project again to get a script pic of the original "costume of length" block, but it couldn't connect to the cloud. Apparently, I opened your project just in time.
Basically just what you did
Crazy cool!
One thing: have you considered a clear block that works on the sprite? I guess that that would be a challenge - you would have to store the original costume somewhere.
I haven't really considered it, but I do think it might be possible, since I could just store the costume when I set the pen down on a sprite (since I am just adding the sprite to a list). However I'm not sure what to do if the sprite changes costumes, or what to do when you pen up then pen down again. I'd probably have to modify the switch to costume [ V] block to save the costume in a variable, and then the clear sprite pen would just switch to the original costume. But if I do that, then people would probably also ask for sprite pen trails and text on costumes (which I could do with the text costumes library).
I have a fix for that, but unfortunately it's on my computer because snap was down when I fixed it (and I'm not at my computer right now).
Edit: the color is an easy fix I can do on my phone, so I just fixed it. Later I'll upload the other changes I made.
Oh okay
