I think the video I posted above should be enough for your case, this is a called interpolation
(lerp) to camera, there are multiple interpolation methods out there, in the video I used a simple smooth lerp method via a well known formula
For other types of easing, I would recommend to use the easing object, it has a lot lerp functions
(check it's help file and built-in examples from Help > Examples > Easing to know how to use it)
Also just a thing that I see repeated a lot, you probably are new to the engine, I would recommend starting out properly first before making your game
- Go over the tutorials from Help > Tutorials
- Watch some good tutorials, like the ones by AlmightyZenTaco (NOT FNAF ONES THEY ARE ALL BAD)
- Check the documentation from Help > Contents
- Understand how events work (they are explained in Help > Contents)
- Play with different objects, check there help files and examples that come with them (most objects do)
- Experiment a lot with different objects, various engine features and editors, object selection, fastloops and foreach loops, groups and comments..etc
- Search the forum or ask for stuff on it (but do not have very specific stuff like how to make camera movement like fnaf) there is also the discord server (pls don't ask for fnaf questions if possible though, we are burnt out from them): Click Converse Discord Server Invite
