Spaceshroom grilling

[goet]

About the PR

Changes spaceshroom cooking to be temperature based instead of the microwave timer. They can now be cooked both in the microwave and on the grill.

Why / Balance

There is a maints room in cog that features a grill with spaceshrooms on top of it, urging the player to cook them. This was impossible before.
/
The cooked item is identical to the previous recipe and it roughly takes the same amount of time to cook. It's possible to cook them in batches, but this shouldn't be a problem as they provide the same amount of nutrients as steaks.

what's the purpose of the fixture?

what's the purpose of the fixture?

It's required for InternalTemperature to work. Without it, the heat capacity of the entity will be so high the internal temp barely moves despite the surface temperature being 100+ more. You can still walk over it and throwing doesn't feel different so I don't think it's affecting anything else, but I could be wrong on this.

Basically without the fixture this will return over 50 (no idea where it gets the FixtureMass from):

space-station-14/Content.Server/Temperature/Systems/TemperatureSystem.cs

Line 173 in d57faf5

return comp.SpecificHeat * physics.FixturesMass;

Which in here will make the delta temp practically 0:

space-station-14/Content.Server/Temperature/Systems/TemperatureSystem.cs

Line 81 in d57faf5

var degrees = joules / GetHeatCapacity(uid, temp);

Values are just copied from the steak, it ended up cooking for the correct time with the temp so I didn't change it.
