I was literally just about to post something about this.
I'm attempting something near-exact to this, but I can't get it right because I don't understand what's being done in the event sheet and what "lerp" is.
What I'm going for is a little more similar to game like Shovel Knight and Mega Man, where the player leaves the Zone and the player motion is disabled while the camera and player are slid into the new zone.
I'm sure I can get the player motion right, but I cannot understand how this works or how to edit the values to suit my layout's size/needs.
