Canvas and Stage Settings

If you use a loop forever, it will follow the pointer.

You want it to go after the user lifts their finger, right?

Going back to what actech said, you can then compare the X&Y of the last pointer position and if it has been that for x time then you can delete it.

It may be incorrect to put the X to X check there, I’m still testing really. But do you see the direction of my thinking?
