So, I've been playing around with pen. Move around the scratch cats to change the pen triangle! For controls and some info, scroll down. Cat A: WASD, Cat B: Up, Down, Left, Right and Cat C: IJKL For more info, scroll down. Eyooooo! Cant believe I got this right! I was toying around with the moving triangle thingy. So I did the three sprites moving around. I had some trouble choosing the keys for the 3rd!!! I chose IJKL in the end, but I could. change it if you want. Then (of course) the pen sprite. So I made the reset positioning so a basic triangle would always pop up on an idle screen. But when I moved the cats, more pen just ended up on the screen (of course). So I put up a duplicate of the pen sprite and on one put a "erase all" block when the reset movement was done, so one could track and trace while the other would configure it, and it WORKED! I am proud of this project here. So, if you plan on using this, as I said in the Notes and Credits section, use with credit!
In projects using one, don't we always need to give credit to scratch! Also scratch AGAIN, for their good ol' mascot Scratch Cat! If you use this in a project of yours, use with credit!
