Center of Gravity and Angular Velocity calculations

[Jecowa]

Does the game consider unloaded chunks when calculating the Center of Gravity?

Also, the wiki indicates that the Angular Velocity is determined only by the number of Spin Thrusters. Is this chart correct?

Number of Thrusters | Maximum Angular Velocity.....
1 | 0.025 rad/s
2 | 0.050 rad/s
3 | 0.075 rad/s
4 | 0.100 rad/s
​

And do all blocks have the same mass for the Center of Gravity calculation?

 

[radfast]

The calculation of centre of mass temporarily loads any chunks which are adjacent to blocks being checked, until it finds air. Most things in Minecraft work the same way, otherwise you could have for example half-trees and half-villages at the edge of loaded chunks.

The mass of blocks is taken to be their hardness, but with a maximum of 30.

The maximum angular velocity is usually the figure in your table, but it may be less than that: for a very large radius space station, it is capped at a figure that produces an acceleration of 1g at the outer limits of the space station. In practice, it is difficult for players to build such a station as it is larger than people think, probably around 500 blocks across. We may change this in future (to produce higher g-force for smaller stations) because with Minecraft physics we can do what we want.
