      Hello,
      sorry don't really understand what you mean.

      Could you draw an example or something? :)

      With Shape object you can create any shapes.

      if you want a free hand lasso tool that can create non-rect free form shapes, you need to note the points and draw a polygon joining them all.

      I mean in Gideros we have Shape:setRegion function which is use to set a rectangle region to draw shape inside. i want the same thing but in various form like triangle.
      thank you. :)

      oh, my bad. setRegion is for TextureRegion object only. maybe i'll think of another way. Thanks, you guys! :D

      Shapes allow you to draw arbitrary filled polygons. For example, here is how I draw an octagon (colour "color") with a border (colour "scolor"):
      local block=Shape.new()
block:setFillStyle(Shape.SOLID,color)
block:setLineStyle(swidth, scolor, 1)
 
block:beginPath()
block:moveTo(-width/2+crad,-height/2)
block:lineTo( width/2-crad,-height/2)
 
block:lineTo( width/2,-height/2+crad)
block:lineTo( width/2, height/2-crad)
 
block:lineTo( width/2-crad, height/2)
block:lineTo(-width/2+crad, height/2)
 
block:lineTo(-width/2, height/2-crad)
block:lineTo(-width/2,-height/2+crad)
 
block:closePath()
block:endPath()
      You can also fill with a texture instead of a solid fill.
