Basic Appliance implementation

[Fris0uman]

Summary

Infrastructure "Basic Appliance implementation"

Purpose of change

Does this #28289

Describe the solution

• Add APPLIANCE flag
• can't install APPLIANCE parts on normal vehicles
• "vehicle" with at least one APPLIANCE is an appliance
• aplliances don't get the vehicle menu, but do get the normal uilist vehicle parts have to control electronics and start washing machines
• Appliances have the "Plug appliance" option that spawn a power cord that you can plug into any nearby vehicle
  - You can plug into an infinity of other vehicle
  - the power cord can't be uninstalled and doesn't drop when the vehicle is destroyed or move away, but it does disconnect

Describe alternatives you've considered

Testing

• Spawn a fridge item

• Place fridge

• Plug fridge into a nearby vehicle with battery power

• Turn fridge on

• Wait a few hours

• Vehicle battery is properly depleted

• Grab appliance

• Try to move

• "The fridge collides with ."
  So collision for appliance is bugged but I have no idea how to fix it

Additional context

This only add the infrastructure and the json for the fridge.
What's missing and should happen in other PRs:

• Something to make a power grid, so I guess some sort of basic vehicle frames that spawns on top of walls
• All of the other possible appliance
• And maybe a map rework to replace furnitures with appliances.

I don't understand the description (or, rather, my attempts to do so results in unreasonable functionality):

• Are you implementing a stationary power grid that's intended for fixed installation exclusively (i.e. not on mobile vehicles)?
• If so, is the usage of the minifridge just a test case example, as we wouldn't want to lose the ability to actually mount those in vehicles (or find them in vehicles)? In fact, for a stationary implementation I'd want an appliance that isn't "mini" anymore...
• The "only" wording is confusing, as it seems to imply you can start out with a normal vehicle, but ones you've gotten a single appliance all vehicle functionality development is blocked, and only the power grid/appliance part can grow. If it's a stationary network the concern here is that it seems to exclude adding things like more power generation. Of course, a dedicated power grid might be restricted to grid functionality only, and require power to be carried to it via jumper cables.
• The frame seems to be a hull part rather than a frame part, which seems to imply you still need a frame to start things off. Wouldn't it make more sense for it to be a special kind of frame that can only support appliances?

None of the data in the zip file is meant to go in the game, this is a quick json edit to get things to instal and try

• Yea an actual fullsize frdge would make more sense
• You can't start out with a normal vehicle since you can't install appliance on something that doesn't already have appliances. It doesn't exclude anything, we either add an appliance power generator or you make a vehicle generator like now and plug it into the grid with a jumper cable.
• the frame is a hull because it's a quick copy paste
