    Saving a shape into file

    edited December 2012 in General questions
    Hi, I'm working on a drawing game app and thus I need to save the shape drawn by the user (not into an image file, it will probably be needed in the future though). I mean, it should be "loadable" afterwards.

    I thought of a way that I can save the x, y coordinates of the each colored pixel into a table stored in a file. But I'm not really sure if that is an effecient way to reach my goal. Any ideas on that?

      Shape._new = Shape.new
 
function Shape.new()
	local shape = Shape._new()
	shape._lastPoint = nil
	shape._allPoints = {}
	return shape
end
 
Shape._moveTo = Shape.moveTo
 
function Shape:moveTo(x,y)
	self:_moveTo(x, y)
	self._lastPoint = { x, y }
	self._allPoints[#self._allPoints+1] = x
	self._allPoints[#self._allPoints+1] = y
	return self
end
 
Shape._lineTo = Shape.lineTo
 
function Shape:lineTo(x,y)
	self:_lineTo(x, y)
	self._lastPoint = { x, y }
	self._allPoints[#self._allPoints+1] = x
	self._allPoints[#self._allPoints+1] = y
	return self
end
 
Shape._clear = Shape.clear
 
function Shape:clear()
	self:_clear()
	self._allPoints = {}
	return self
end
 
function Shape:getPoints()
	return self._allPoints
end
      Basically it stores all the points internally and provide new method for the Shape object - getPoints to return table with all the points in shape

      You can either create init.lua file and copy the code into it,
      or simply use GiderosCodingEasy with some other additional features
