I did the zelda style scrolling in one event hehe
I think we need a new system expression which is similar to clamp and similar to lerp. I need a name for it...but basically you give it a value, another value, and the amount to move the first value towards the second value...
so it's like this:
return source + clamp(destination - source, -dist, +dist)
hmm...
one disadvantage to my system is it doesn't pause the game
