This is just a fun animation where a hippo and some other sprites fly in front of and then behind a pen-draw mountain but always in front of a pen-draw sun.
I'm using the SciSnap blocks from the library which don't work well and are slow.
But drawing the mountain was supposed to part of the animation. How do we fly sprites in front of a pen drawn sun and behind a pen drawn mountain? If the sun and the mountain are on the pen layer at the same time won’t they both be in the pen trails?
It would go something like this
[scratchblocks]
forever {
warp {
clear
draw sun :: pen
move (10) steps
stamp
draw mountains :: pen
} :: grey
} :: control
[/scratchblocks]
I'm really confused. If you want the background bits to be there at the beginning, just save them in sprites.
Oh, are you thinking that CLEAR will make the sun disappear? Since you've given a sprite that costume, it'll still be visible when you clear the pen trails.
