Once the air group gets to the 20 ticks with no big changes, it will dismantle itself with no compares. At the 10 ticks the group will still merge itself.
Testing has revealed that it reduces the sluggishness of the game, though it will spike from lag when the singularity is loose. Thanks to ChuckTheSheep for suggesting it.
Server owners who want to keep set background enabled can do so by changing the define.
-mining rooms will be generated before the air controller is created
-changed the total of moles of the NO2 turfs from 2000 to 6000 to compensate the replacement of the canister that spawns like 36000 moles on top of it for a normal canister. I'm talking about the NO2 canister inside of the chamber in atmos. (I will replace the canister in another pull request)
* Replaced "fire" with SPAWN_HEAT. You will have to use it in conjunction with SPAWN_TOXINS to spawn fire.
* Added flags for HEAT, COLD, TOXINS, OXYGEN, CO2, NITROGEN, N2O, FUEL and AIR.
* Stopped the fuel and n20 option, in spawn_air, from runtiming.
* Added toxins as a spawn_air option.
* Removed all use of the fuel option and replaced it with toxins, since fuel does not work with LINDA anymore.
These doors didn't work previously, as the bound width needs to be set properly. Additionally, LINDA was tweaked to properly update in the case of multitile objects such as this door (actually this door is the only such, currently, but if more doors or other multi-tile objects are added, this will help)
Note that until #1206 is merged, this door has a blind spot where you cannot click it because you are not in range of the leftmost tile; old click code only uses the canonical location (loc), meaning the right tile is not counted for range checks.
