clearing pen in specific areas

Pechu317

i think it would be useful to have some way to clear pen in specific areas, because it is quite tedious to program a sprite to retrace where it has previously drawn pen, and DID program that, if you had a pen line that went over a switch in background colors, it would be even harder to sync the pen changing color with the background changing color.

And how would this work, exactly? You're being very vague.

sorry, i accidentally hit enter before i was done typing. whoops

But pressing enter doesn't post it- it just goes to the next line.
Anyway, when I said it was a bit vauge, I meant how it would work, not why it was useful. I can see quite easily why the general idea would be useful, but how would it be executed? What would the new blocks be? That's what I really meant.

probably something like this:

clear pen from (starting x) (starting y) to (ending x) (ending y)::pen

if my scratchblocks dont work the first time i'm not surprised

That's still pretty ambiguous. Would it run from pen size? Will it be a line, or a square?
Even then, I don't think that's the best way of executing the idea no matter what the answer is. They just look really awkward to use.
(By the way, your scratchblocks is fine)

okay. I just thought it would be nice.

I still feel like the concept is good, just the exact execution I think could be improved on. Could you think of anything else?

Support, this would be useful for pen platformers!

not really.

Like this?

clear pen x () y () w () h () ::pen

ooh i like that. although it would need to be explained which direction the “height” and “width” inputs go.

Actually I think that it would be a lot more practical if there was something like:

set pen to eraser :: pen

Support. Right now you can only really precisely erase certain pen areas if you have a solid background in your project. If this was implemented, then you could clear pen areas effectively in any visual circumstance.

haha i'm quoting you even though ur signature says not to
well then if you did that you would need to retrace the pen you would want to erase unless you set the size to something huge, and then instead of a rectangle you just have a giant eraser circle, which i don't believe is useful
