Example: [ [300, 10], [400, 5], [410,150], [320, 100] ,[290, 20] ]

  • units::String
  • lineWidth::Int64
  • lineColor::PsychoColor

Methods:

  • draw()
source

draw(various shape types)

Draws the shape (Line, Rect, Ellipse, TextStim, etc.) into the back buffer.

Example:


	newRect = Rect(myWin, 
			100,			# width
			100, 			# height
			[200,200],		# position
			lineColor = [255,0,0], 
			fillColor = [255,128,128] 
			)
	draw(newRect) 		# in PsychoPy this would have been newRect.draw()

setPos()

Set the position of the object, usually the center unless specified otherwise. Example moves an image rightward by 100 pixels per frame, starting at 300 and ending at 500 pixels:

	for x in 300:100:500
		setPos(myImage, [x, 400])
		draw(myImage)
		waitTime(myWin, 100.0)
		flip(myWin)
	end
