unity3d - How to Edit the character motor script to enable slide on tagged objects rather than it is greater than slope limit? -

i working on 2.5d platforming game on unity3d , need character slide on tagged objects rather being on slope limit. using character motor , fps input scripts.
have found line enables slide , follows:

function toosteep () {     return (groundnormal.y <= mathf.cos(controller.slopelimit * mathf.deg2rad)); } 

this condition on slope limit, how able edit function return true if game object character on tagged "slide" example.
appreciated thank much.

first, add new boolean field charactermotor script , throw in "or" in if statement checks if player grounded and if ground steep, looks this:

if(grounded && (toosteep() || somenewbool)) 

then, attach trigger box collider object (don't bother tags on other object), , attach monobehaviour following function in it:

function ontriggerenter(other:collider)  {     if(other.tag.equals("player"))//replace "player" tag marked player with.     {          other.getcomponent(charactermotor).somenewbool = true;// new bool added charactermotor script     }  } 

and function looks this:

function ontriggerexit(other:collider)  {     if(other.tag.equals("player"))     {          other.getcomponent(charactermotor).somenewbool = false;     }  }
