The space is not necessary I put that in just to make it easier to read. Note that I separated the numbers with a comma. Let's say I only want to wiggle at a pace of one wiggle a second, fairly sedate, and let's say I want to wiggle by 100 pixels. I'll type P to reveal the position value, hold down Option or Alt to enable expressions for Position, click, and in place of the default expression transform.position, I am going to type wiggle, open parentheses, and I need to enter two numbers, how fast I want to wiggle and how much I want to wiggle by. In other words, I want to wiggle its position. Let's say I want this gizmo to wander around the screen. In it I just have a little gizmo in the middle of my screen just doing his own little animation.
First I'll clean up my display by closing all of my previous comps and open up 05-wiggle*starter. Next, I'd like to show you our favorite expression of all, Wiggle.
