This parameter executes the enclosed custom expressions prior to presenting a stimulus animation frame. The script can change properties on a given stimulus such as size, position, or color according to custom logic in order to implement complex animations. The animation paramter must be set to "dynamic" in order for this code to executed.
The following shape includes a custom animation that alternates between to screen positions:
/ shape = rectangle
/ color = red
/ size = (50%, 50%)
/ position = (50%, 50%)
/ animation = dynamic(500, -1)
/ onanimate = [
shape.redsquare.hposition = 75%;
shape.redsquare.hposition = 50%;
values.toggle = !values.toggle;
