Create a rubber/eraser like effect

JagonApps

Hi
I have recently created a pen like tool similar to the one in the game example: 'Drawer ORBZAMPLE'
But I need a rubber/eraser tool that can be used in-game by the user - what is the best way of doing this please????

2 ways;

1. if you have gameAttribute: colorSelected
on eraserActor:
Rule: when
Event: touch is pressed
-changeAttribute: game.colorSelected To: drawing background color

2. or on the pen LineSegmentActor:
Rule: when
Event: overlaps/collides with eraserActor
--changeAttribute: self.Color.Alpha To: 0

Thanks I tried your second suggestion but ran into issues that are not directly related.

I think I'll just scrap the rubber

… sorry … forgot … the brushSize for the eraser should be very small…
so that other lines are intact … just the segment that user is dragging it to … change Alpha
