I am sorry to keep asking but im desperate, I always try to figure it out myself before asking.

I would like to make a moving platform that when I step on it it starts moving one direction, in my level I want to make my characther step on a raft that moves me through a tunnel filled with water.
kinda like the second level of superghoulsandghost for snes.

the other thing is camera when im in a walled environment.

if I turn left and I'm near a wall I disappear and all I see is the outside of my level.
here are some pictures that could explain it better.

I know it has something to do with camera.genius but dont know what.



this is me just facing normal, now I will turn left.



and this is the last which show outside my level.



Does anyone know how I can fix this ?
