How do I draw on the screen like a white board?

Sorry if this is super simple, I'm just starting. I'd like to draw on the screen to make lines, like drawing on a white board. Change the color of the drawing pencil. Draw arrowheads at the end of a line. Things like that. Any suggestions?

Thanks!

You'll want to familiarize yourself with the drawing canvas plugin.

Keep track of where your mouse position is in a variable at the end of every tick, so you have the information of where the mouse was the last tick, and the current position of the mouse at any given tick. You can use that information to create a line between those two points.

Ah, perfect. I was searching writing on white board and chalk board and nothing was coming up.

Thanks so much!
