[1.70b] [SMP] Jetpacks

I'm seeing a similar problem. On SMP, my electric jetpack cannot be set to hover mode. In SSP it appears to work correctly.

Use the M key

Did some more testing. It appears [electric] jetpacks are having other issues in SMP as well.

While wearing an electric jetpack and 3 pieces of nano armor:

-Mode key does not toggle hover mode. I tried a few different mode keys. If the mode key is held at the same time spacebar is held, ascent is slow, similar to hover mode. Hover mode works correctly in SSP.

-Landing takes fall damage that appears to be related to the total vertical distance traveled. Taking off from the ground, going just a little ways up and then landing (using the jetpack to keep a low velocity) results in zero or very small fall damage. (~half a heart) If I take off from the ground (~y=66), fly to max height, and then land, I will take several hearts of damage, even if I slow my descent using the jetpack. Finally, if I take off from the ground, go to max height, and then descend to near ground (don't land) and ascend back to max height a few times, when I land I will die from fall damage no matter how gently I touch down. This behavior is not present in SSP.

-Jetpacks do not give the 1.5 armor units they do in 1.64. This behavior occurs in SSP as well, not sure if it is intended.

Jetpacks are pretty broken on SMP and it's very hard to fix, requiring baseclass mods

I used an electric jet pack with s solar helmet and i was able to get it to run indefinitely during daylight. it seemed to be toggling on and off very quickly but the overall result was that it ran fine without a noticeable power deficit. i report this as a bug because letting it charge on the ground with the helmet and then flying it without the helmet doesn't yield anything close to a 1:1 ratio of charge time to flight time. For now you can fly pretty much forever in the daylight.

Same issue here. Jetpacks were fully functional on my server in 1.64 but no longer have proper hover mode in 1.71. Holding m slows my ascent, but the m key otherwise performs no function for the jetpacks. I tested my mining laser and that still works, my old one anyway.
