This is just a booby trap for new people.
Rather than having it so every movement is already on delta time, they make it so you need to add a special little formula to make your game actually work the same on every system. There is NO hint about this little secret unless you sift through the tutorial section and stumble across the delta time tutorial.
It is "broken by default" in my opinion.
They should make it cryptic and difficult to make things NOT delta time, not the other way around.
There a are quite a few little things like this. They make it so new people can see a working game in preview, yet when they export it it will be nearly non-functional on their clients machines.
In my opinion this is a form of "Bait then switch".
New user sees that their little project works in preview, so they buy C2.
Later they find out they were tricked, and their game is not playable on any system except the developers system in preview mode.
I lost almost a weeks worth of time trying to convert a finished game to use delta time. I ended up just abandoning the project because it would have been less time to just start over from scratch.
TL;DR
Do not attempt to make a game with C2 unless you read EVERY tutorial, Every Blog entry, and EVERY forum post. You might miss a cryptic little thing like this and your project may not be recoverable.
Do not even start a project unless you have tested every function you might need. You need to test in both preview and the exported game.
"The Obvious way", and "The easy way" are almost always wrong with C2.
