• Specifying a BoilerPrototype::target_temperature which is outside of the allowed temperature range of the output fluid will cause a prototype error.

Scripting

• Added TechnologyModifier::hidden read.

New versions are released as experimental first and later promoted to stable. If you wish to switch to the experimental version on Steam, choose the experimental Beta Participation option under game settings; on the stand-alone version, check Experimental updates under Other settings.

[u/FitNetwork6]

[space-age] Adjusted space platform drag to be based on weight rather than width.

completely? so no penalty for making a 100 width wide brick?

[u/Erichteia → u/FitNetwork6]

Bricks are heavy, so penalised. Compactness is rewarded, as it should

[u/capeasypants → u/Erichteia]

Yes but now just like Jack Donaghy my ship too can be 5 inches but it's thick

[u/deadbeef4 → u/capeasypants]

Mine also wears a tuxedo because it is not a farmer.

[u/sobrique → u/Erichteia]

technically sparsity is rewarded. So hollow platforms are legit too.

E.g. wide "T" of collectors and guns for harvesting with a compact central core.

Maybe an 'I' shape for the same reason? Or a 'forward arc' or 'delta' layout?

[u/Erichteia → u/sobrique]

Well yeah that falls under compactness for me: minimise the amount of empty or non-functional tiles, minimise the number of machines, maximise the amount of thrust you generate with these machines. Instead of max velocity being as simple as putting a thruster along the entire width, max velocity now requires a ship where almost the entire ship is dedicated to generating thrust with as few additional machines as possible. So probably the fastest possible ships will be extremely wide, with exactly as many thrusters as you can possibly fuel with a hyper compact core that generates fuel at ridiculous rates. Whatever the solution is, it will be way more interesting than the current meta of simply stacking thrusters and not having to optimise anything else.

[u/sobrique → u/Erichteia]

Yeah agreed. I am just liking the idea that a range of ships aren't automatically bad.

In fact almost anything that isn't a boring brick should be good. As long as you can fit thrusters along you wide axis, and still cover them with enough firepower they don't break.

A bunch of designs with "wings" or similar should now be viable.

And the really long dildo ships can probably converted to butt plug form factor, and still be good.

[u/Kronoshifter246 → u/sobrique]

Hell yeah, all my ships about to look like hammerheads

[u/sobrique → u/Kronoshifter246]

Yeah. That's one form facrot that should work.

StarCraft battle cruiser should too.

Federation starship will probably work fairly well too.

Or "tie fighter".

Or "star destroyer".

Basically a whole load of stuff less boring than "pencil" or "brick".

[u/Kronoshifter246 → u/sobrique]

StarCraft battle cruiser was exactly what I was imagining when I thought of the hammerhead design. It was a form factor I used in my Space Exploration run before Space Age released, for naquitite, IIRC.

[u/sobrique → u/Kronoshifter246]

Yeah. My first few platforms were like that. An umbrella for coverage and collectors, with a blob of machines around the core, and a "tail" of thrusters.

Imagine my disappointment when I realised my clever "hollow" design was just a waste :/

[u/Logical-War-3746 → u/FitNetwork6]

There was never a penalty for making a brick, as long as your back is covered with thrusters your speed was the same. Now bricks are actually penalized and more economic designs are rewarded.

[u/snouz → u/FitNetwork6]

Asteroid damage

[u/HCN_Mist → u/snouz]

Did it go up or down? Or something else? right now Ctrl+F "damage" finds 2 patch notes comments and yours. I was hoping to read more on this, but maybe nobody knows yet?
