A problem with random falling objects shaking

Above I am creating an event where polygons fall randomly.
I want to set it to fall randomly between 45 and 135 degrees left and right without falling vertically,
but it falls almost vertically. And as it falls, the shapes shake slightly.
Any help would be appreciated.

The shaking is because you are applying a random instant force every frame at a random angle, and not the same force every frame.

What you really want to to is apply a force at the angle of the shape.

I can’t quite remember, but that move box event may need to iterate over each shape, by using a repeat for each object event, with Shapes as the object. Apply the force at the shape’s angle as the action.
