I'll be fixing the inability to revolve while hard tied in the next release or so.
:blink:
Please explain!
You shouln't ever be able to revolve with respect to a hardened tie..... except by setting .fixang or one of the new .tiang() settings on the offending tie.
I've been talking about this for a while. Specifically I put it all together in the tie thread.
Bots in hardened ties will act as ball bearings. Bots will only be able to change angles
between two ties by applying nrg to move it. That is, the angle between where the bot is looking and a single tie is meaningless for anything but the bot's own information. That means the bot is free to rotate around while still manipulating ties, which is much better for reasons Ulc has clearly demonstrated.
The exact nature of the energy needed to move two ties I'm still researching, but it will probably be similar to the amount of energy muscles have to expend to move two bones in relation to each other. You'll apply force X and drag and added mass from the ties will cause forces in opposition which can move you forward or to the side, etc. The force of these opposition forces depends on the viscosity and density (depending on laminar and turbulent flows) so is user definable, but forces will always be realistically based in physics.
Now you know what I've been doing for the last 4 days.
