## About The Pull Request ##### Code bounty for holinka4ever Adds a furnace equippable to the back slot, which when active (it is a lamp), will form a bubble of space protection, affecting the user and people nearby, and will last 5 minutes before it dissipates and needs to be re-formed. This item requires a pyroclastic anomaly core to activate, while the bubble itself can only be formed in pressurized environments. It's researchable in the Anomaly technology node. The downsides of the item is it requires 2 hands to hold, can't be inserted into storage items (as it's bulky), can only be equipped to the bag slot, and has slowdown while on, which only affects you when you're in gravity anyways. ## Why It's Good For The Game The pyro anomaly is currently one of the more useless anomaly cores, not even getting a unique reactive armour variation. This hopefully gives it some purpose as a good tool to keep people alive in a spaced area at a good cost to the user. This is an item that shouldn't be overpowered, but also isn't just a selfish tool- when someone's crafting this item it's specifically aiming to help people, which I think is a benefit. ## Changelog 🆑 JohnFulpWillard, sprites by PopLop add: Added a new pyroclastic anomaly locked item, the Space Furnace. Grants space immunity to people nearby while active. /🆑

/**

* This component behaves similar to connect_loc_behalf but for all turfs in range, hooking into a signal on each of them.
|
|
* Just like connect_loc_behalf, It can react to that signal on behalf of a separate listener.
|
|
* Good for components, though it carries some overhead. Can't be an element as that may lead to bugs.
