update custom function more than 1 time per frame

Hi, I am wondering is it possible to update my own custom function more than once per frame. I know that I can configure FixedUpdate but I need something faster to return bool from Physics.CapsuleCast()

 

Why do you need something called more often than FixedUpdate?

 

Well I am struggling with a character movement script, I want to make my own one because CharacterController does not fit my need... Currently I have something (absolutely not working like I wish) I have done so far...
I don't need physics for my character but when I use transform.Translate() it goes into other objects.

Am I on the wrong path and should use something totally different?

PS. Jumping still in process

Code (csharp):
