Hi eveyone,

is it possible to somehow use a the clear() function on a line that has been dynamically drawn only at a certain point? i need a line to be drawn and then gradually erased with time. currently i’m drawing a green line and then a few seconds later, a start up a function that creates a white line above it. it works great if this line is above a white background, but if it’s above some other element, you see a white line 🙂

any thoughts?
