This was released a couple of days ago now actually, but had a bit of trouble getting the video sorted.
Qiso has a new cameraFollows() function that works as a delayed variant of the lockCamera() function, giving a smoother follow mechanic. In a nutshell, if you tell cameraFollows() to follow a specific character, it’ll wait for that character to leave the current tile and then chase it around instead of literally ‘locking on’.
