Question Raycast2D of enemy

Hi,
I have a problem with the patrol of one of my mobs in my project of "2d castlevania". Im new in unity and dont know the diferent about my enemies. I make a RayCastHit2d to see where is the final of the platform. My Slime works alright but my skeleton doesnt want to stop and change his direction.
The code is this:

And the Enemies:

I give my a parameter the transform of the object "ComprobacionSuelo" = g_ControladorSuelo and the distance of the raycast.
If you can help me i will be very gratefull

PD: I created the slime with a prefab and the Skeleton with a PNG and sprites the animations.
