Light blocks up

Hi,

How would you light blocks up around a player - like fog of war - would you need a shader to do this and how would you cycle night and day, so game goes darker (I guess this is just a simple global shader)? Or is there another way to do this such as getting player position and changing the tint on the blocks around them? Screen shot of my game so far - big sandbox game, procedurally generated, would just like to add lights to it :slight_smile:

This maybe in the wrong section…I’m using libgdx for this.

Many thanks
