Is this instruction only lite-c compatible?!

Or we can use it with c-script too?!
& if yes, How we can use it with c-script?!


I am forced to use c-script for one of our clients
But,,

The Dynamic lights flicker as camera moves,, as a solution I tried to type light_view = null; into main function, but it says it is unkown and gives an error

Please need help from experts
