generating heat

[steuben]

I'm trying to hack up a part so that it will generate heat as it converts resources to elec. I think I've got the right coding but it still sits there as cool as a cucumber, despite the silly large numbers I've put in. So I know I'm either mis-invoking the heat or missing parts of the invocation

"TemperatureModifier" is float curve not a single number.

TemperatureModifier
{
key = 0 100000
key = 750 50000
key = 1000 10000
key = 1250 500	
key = 2000 50	
key = 4000 0
}		

 

[steuben]

So if I want a flat curve, always generating the same amount of heat, I would construct it something like:

TemperatureModifier  {
key = 30 0 
}

And so i have my head around it.

The second number is the slope of the curve at that point, and the first is the value?

[Deimos Rast]

the closest comparison I can think of is Interstellar's WasteHeat resource.

Alternatively, you could maybe have a converter that only operates within specific temperature ranges.

[steuben]

I've tried both

   TemperatureModifier
   {
     key = 1 4000
    }

   TemperatureModifier
   {
     key =  4000 1
    }

I've also tried

   TemperatureModifier
   {
     key = 0 4000000
     key = 4000 4000000
    }

It still stays the coldest part of the craft.

 

There are any  docs out there for temp modifier?

Okay i've got it generating heat. It turns out I need to add modulecoreheat.

 }

}

Now I want to add a complexity to it. The hotter it gets the faster it gets hotter. Is it possible or do have to fake it a bit?

The keys in TemperatureModifer are temperatures while the values are heat fluxes. So you can create the following

key = 0 50000
key = 100 100000
key = 500 150000

That will cause the part to produce 1000kW at 0K, 2000 kW at 100K and 3000kW at 500K. The values in TemperatureModifier are in kW*50, so if you want to produce say 10 kW, you write 500. 

[steuben]

The system interpolates linearly between the two nearest defined points, and flat lines after it falls off the list? So using those numbers at 600 it will still generate 150000, correct?

So short of manually defining the points up to the melting point, and maybe a little beyond, of the part there is no way to create a runaway effect. Well short of getting fancy with module manager, or some other coding, which is more lifting then I am prepared to do for this.

[wasml]

There's a float curve editor for Unity - works in the unity editor (Not sure if it works in the KSP 1.2 version of unity). Shows you the curve you're creating.

 

[steuben]

I think I have my run away condition... but I can't see to get control back of it. I let the temp spike up to 1300, turn on all the radidators, the temp drops down to 400 and then runs its way back up to the temps that will slag the part. I think it has something to do with CoreEnegry on the thermal debug display.

I don't think I've got the cooling hooked up right, or enough flow for the heat I'm generating.
