Gideros Studio has a simple way of creating graphics in the way of Shapes.

To create a shape, you draw it using line commands. Once created, the shape can be rotated, scaled, ... 

local myShape = Shape.new()
myShape:setLineStyle(2)
myShape:setFillStyle(Shape.SOLID, 0x9900ff)
myShape:beginPath()
myShape:moveTo(1,1)
myShape:lineTo(100,1)
myShape:lineTo(100,100)
myShape:lineTo(1,100)
myShape:lineTo(1,1)
myShape:endPath()
stage:addChild(myShape)

This will draw a purple rectangle:

Manipulating your shape

myShape:setPosition(75,0)
myShape:setRotation(45)
myShape:setAlpha(0.5)

Style

There are a few options for setFillStyle:

  • Shape.NONE = No fill
  • Shape.SOLID = Solid color fill
  • Shape.TEXTURE = Fill your shape with the content of a PNG

This will set the shape as solid with a blue color filling and a transparency of 0.25: 

setFillStyle(Shape.SOLID, 0x0000ff, 0.25)

There are also a few options for setLineStyle:

  • width
  • color
  • alpha
