Alright before you start going crazy and saying "NO NO NO" think, if the lighting engine was updated to have darker shades in closed areas: Tunnels, sewers, Buildings. You are in a sewer. You can't see anything. the enemy is right infront of you but you can't see his name/body. *presses F* *CLICK* *BANG BANG BANG* Dead.
Good side of a flashlight: Helps in darker places to see, and would be a good tactical ambush type thing when not turned on in a tunnel or sewer.
Bad side of a flashlight: It will increase the numbers of campers inside of dark areas.
Good side of lights: Helps see in dark areas, and could be destroyed to regain the light and place it back. Maybe hold a button like L and left click when in the blocks menu, you could make some nice structures with lights in em'.
Bad side of lights: Could influence more spamming of random blocks.
Muzzle-Flash: Idea by Diggy. Might look cool, but could cause performance problems along with the flashlight. Your choice!
Dark areas where you don't see a great distance ahead would also influence the use of a shotgun. (No more bright tunnels (except for lights) to let you snipe from the fog at people!)
Also flashlights give off a glare, so when you look into a flashlight you will see a bright flash on your screen.
Created a poll for the community.
NOTE: Don't just go NO NO NONONONO, give me a reason for why you don't want them. If you fail to do so, you shall be ignored, and your vote won't count in my opinion.
NOTE 2: Don't just go YES YES YESSESES Either. Gotta put some good information on why you want it.
Note 3: Be nice, if I see flaming, and hatred going on I'm going to request a lock. If you flame and spam for just that reason you will be man handled by staff.
