In the last line the variable named answer receives the value True. drawn sequentially in lines progressing from the top of draw multiple stimuli.

We have to enclose text strings in quotation marks. PsychoPy is a software library written in Python, using OpenGL to generate. In the third line the variable s becomes the text string None shall pass. In the second line peterSmithAge becomes the real number 17.5. Stimulus to (PsychoPy) the self.screen property In the first line of code, the variable with the name i becomes the integer number 17. Nothing - draws an ellipse on (PyGame) or adds a GratinsStim

H - height of the rectangle in which the ellipse is drawnįill - Boolean indicating whether ellipse should be filled Figure 4 PsychoPy Tutorial Step 3: Loops. This produces a smoother (less-pixelated) line. interpolate ( bool) Enable smoothing (anti-aliasing) when drawing lines. depth ( int) Depth layer to draw the stimulus when autoDraw is enabled. Your Builder window should now look like the below figure. This value is used to modulate the contrast of colors passed to lineColor and fillColor.

W - width of the rectangle in which the ellipse is drawn Click Insert Loop then click on the left and right sides of the trial routine. Y - y coordinate of the rectangle in which the ellipse isĭrawn or None for a vertical centrally drawn X - x coordinate of the rectangle in which the ellipse isĭrawn or None for a horizontal centrally drawn (Circle(pygaze.expdisplay, radius=r-pw, edges=32, pos=pos, lineWidth=pw, lineColor=colour, lineColorSpace='rgb'))ĭef draw_ellipse(self, colour=None, x=None, y=None, w=50, h=50, pw=1, fill=False): (Circle(pygaze.expdisplay, radius=r, edges=32, pos=pos, lineWidth=pw, lineColor=colour, lineColorSpace='rgb', fillColor=colour, fillColorSpace='rgb')) The two critical arguments to create a line are start and end, which are each two-item lists that specify the x and y coordinates of the start and end points of the line, respectively. Lines Perhaps the most simple shape stimulus is a line, which we can create in psychopy using Line. Pos = pos2psychopos(pos,dispsize=self.dispsize) Using psychopy, we can also easily draw a variety of shapes. Nothing - draws a circle on (PyGame) or adds a Circle stimulus Pw - penwidth: circle line thickness (default = 1)įill - Boolean indicating whether circle should be filled or Shapes A variety of shapes can be drawn in PsychoPy, for example, rectangles, circles, polygons, and, of course, lines. Pos - circle center, an (x,y) position tuple or None for a None for the default foreground colour, self.fgc Def draw_circle(self, colour=None, pos=None, r=50, pw=1, fill=False):Ĭolour - colour for the circle (a colour name (e.g.
