Pitch darkness in space

[GeneralZadrot]

The idea is to make a day/night cycle in space. The platforms rotate around the planets, and when the platform is in the shadow of the planet, it should become very dark and the efficiency of the solar panels should drop to 0%.

This will complicate the design of the platforms and will stimulate players to use nuclear reactors in space.

Help with an example of a line of code for a script that would activate the day/night cycle for all platforms in space.

Thank you in advance to everyone who responds!
