You'll have to elaborate a bit. Are you using your own behaviors for movement? What do you mean by "sides of platforms"?
The cutscene pack replaces the miscellaneous pack, as it contains everything in the miscellaneous pack and more. Both packs have the "Player Control" behavior for platformer movement and it works pretty well. Issues with actors getting stuck while using it would mean problems somewhere else, such as the actor's friction settings, or if your player is standing over a row of missaligned actors.

Sry ya im pretty new at this. I mean when i make the character jump he sticks to the sides of tiles rather than falling if i keep holding down the key. Sry I looked for someway to message you directly

That is independent from your code. That issue is related to friction. This video explains it in detail: 

The short of it: set the friction to 0 for your actor. My "Player Control" behavior from this pack already handle slowdown and everything else.
