Reverse engineering a capx with one event, while someone told you how to create the event above?
You are right, that's not being lazy..
There are other words for it though..
While typing in the event as shown above you'd have noticed after typing the dot behind textbox a menu pops up showing all the different things you can put behind the dot. This is actually true for every object you type the name in for. So if you ever need the height of an object in a "formula" object.height will do it for you.
Reverse engineering, while possibly usefull, isn't the same as programming. Programming is solving issues while building something. reverse engineering just shows the one possible solution to an issue someone decided to use. It could be very possible there are easier ways to solve the issue, but by reverse engineering you'll never learn those.
But if it works for you to ask people to do unnessecary work for you, that's fine..
