Oxygen (special)


Recommended Posts

This is probably common knowledge, but I was amused to see in my LOx cooler that at the moment of condensation, oxygen (gas) turns into a packet of oxygen (special) at a temperature of absolute zero.  This appears to last for a single tick before becoming a droplet and then turning into oxygen (liquid) at the expected temperature.  I haven't been able to catch this on the boiling side, just the condensation.

It intrigued me because it is a special packet type and it didn't have the temperature of either the liquid or the gas phase.

Yes I'm weird and I often just sit and watch temperature fluctuations of things.

Yup, this is normal (for ONI values of normal).  I think what's happening here is a consequence of the mass in each tile being tracked separately from the element in each tile.  It allows tiles to be in states that don't really make any sense.  In this case the tile briefly has a mass of 0, but it's element is still set to oxygen gas and not vacuum (which in the code is handled as a gas with some special-cased behavior).  I'm not sure what the exact display logic causes it to show "(special)", but a tile containing an element other than vacuum with 0 mass seems to do it.

When a tile of gas condenses, it turns always turns into a droplet which is no longer part of the simulation grid.  The tile the that the oxygen occupied is then briefly set to 0 mass, but the element doesn't change until another element flows into the cell on the next tick.

It was said that debug monitoring slowed down the EA. Now, after release - is it any better?

I am not sure they removed it yet. I can understand they wanted to get it out before the festivities, but it still has more bugs than it should IMO.

This is not just a forum about a game , its a support group , because ONI is a very addictive game, it's like having a Formicarium with ants , you catched a queen and you can watch hours and hours his behavior, not because you are study them, because you like it. 

I also like to watch temperature fluctuations. And also did notice strange things happen when gas condensing to liquid. Although did not manage to get any (special) material, but I suppose vacuum in the tile that holded gas which became a liquid, is pretty understandable mechanic. Also you can notice this effect when slicksters are feeding. They make vacuum in tile above and below them when they suck the co2. I think same should be with pufts.
