Various bug reports and feedback

[Percebob]

Firstly, kudos to the devs for such hardwork in making this great game/simulation and for giving us access to the alpha.

I'll start with the bugs I have encountered so far (more will come as I test the game) :

-Temperature locking(***) : I am unable to manually modify temperature on all bodies in the solar system simulation, also throwing huge chunks of rock at them does not change their temperature either. Happens every time(?) with most simulations(?). *** Figured you must disable climate to change temperature.
Secondly, when I actually can modify it, values taken seem random, for exemple : Adding 200°C when body is at -50 ends up at 50°C (not exact numbers here)
 
- Areas of earth not melting when they should, already sent a bug report using IG tool, but I'm going to throw it in here anyway : (I think a picture is better than words on this one, when I find out how you can put pictures here)

Optimization wise, the game stands much better than the first one, though I have some weird frame drops when not much is happening, for instance when only two bodies are simulated and one of them has sea level changes the game drops below 30fps while when simulating the whole solar system it stays at a strong 60fps.


Not really bugs but things that bothered me :

-Planets not loosing mass when sublimating/turning into giant comets at temperatures exceeding 3000 K
-Bodies fragments a bit too big IMHO (I'm no scientist but some fragments just seem too big, especially when looking at their mass)

I can actually heat up every planet except earth with asteroids on a new simulation quite easily.

[Percebob]

Really ? I must have missed something then, how do you do it ?

[Unnamed25]

I just throw asteroids at them with the "1" key.
Mars gains a lot of heat with those asteroids

[Percebob]

Ha, most of impacts don't affect it in my game, unless it's a giant one (Venus or Mars colliding into Earth)
Edit : In most simulation modes (not Collision for instance)
Edit 2 : In fact even giant impacts don't change the temperature
Edit 3 : Alright, I get it, you must disable climate to change the temperature

[Unnamed25]

Yeah climate change is a little bugged with temperatures

- Temperature locking : Right now you can't edit the temperatures, as those are simulation controlled. So you can expect some weirdness if you try. We'll have to see about a better way of handling that UI control, so it makes more sense. Also, if climate is enabled, it does not take into account impact heating, so the surface temps won't change. (That's a feature that needs to be implemented)

- Not Melting : I'll talk to Georg and see if we can get that fixed.

-Planets not loosing mass when sublimating/turning into giant comets at temperatures exceeding 3000 K
They are losing mass, but it's not enough for you to really see easily in relation to the mass of the entire body. On a smaller body, you should be able to see them losing mass.

-Bodies fragments a bit too big IMHO (I'm no scientist but some fragments just seem too big, especially when looking at their mass)

It's one of those counter intuitive things, but the smaller a body is, it actually has a lower density and therefore a larger radius. Large bodies are crushing in on themselves, and will compress the radius down based on their local gravity field. If you were to plot the radius of a body as you massed it up, you'd find it has some interesting bumps as it approaches those critical points.  That said, it's something we've noticed here as well, and we're still mulling over how best to handle it.
