Boxes with known issues

[EmeraldMT]

Issues reported by players:

257 - Bouncing on trampolines isn't working properly.
679 - Players get stuck on top of trapdoors underwater.
777 - Gravel fell on piston and broke it. (can happen in the tutorial and other boxes too)
819 - Player can no longer jump high enough to press the switch above some closed doors.

Misc collision issues. Mech links randomly disappearing.

376 - Same trampoline problem as 257
312 - Trampoline bounce/jump height is less on 5.3.0 making some trampoline jumps impossible.
848 - Similar problem as box 679 with trapdoors underwater.

A small problem I found with a lot of boxes is that they use "levers" instead of "filtering button signals" for doors. If you are able to hit the lever from both sides of the door you'll end up locking yourself in. It happens to me frequently.

51 - sequence break (get second nexus first) by jumping from the roof of a house to a vine on the bridge

I'm adding +1 to the trampoline issue. Just ran box 312 - the trampoline jumps may technically be possible, but the inputs are probably frame-perfect, it's hard to tell but out of maybe 50 tries i got like 1 jump on the first trampoline there, and never managed on the second one. There's 3 total in that room, meaning you have to do the jumps perfectly 3 times, which is really unlikely.
Edit: Tested on Minetest 5.0.1 - the trampolines definitely bounce higher, or at least, holding spacebar registers to let you jump higher much, much better. Box 312 (and probably the other ones mentioned here) are actually doable on 5.0.1

• Box 75 also has the trampoline issue. Impossible to do in 5.6.1, but easily doable in 5.0.1

There was a PR against Minetest engine that fixed the trampoline regression that was merged some time after 5.6.0. Since @ZenonSeth said it was not in 5.6.1, would someone like to try it with 5.7.0-dev?

@Montandalar I downloaded the latest 5.7.0 release from Gitlab and tested. It seems better

• Box 75 is doable, there's only 1 trampoline jump and it works fine now.
• Box 312 has 3 trampoline jumps, the first is doable on 5.7.0 but the second is not. Went back to 5.0.1 and it seems it relies on the fact that if you keep jumping on a trampoline, you'll gain a bit of height, which does not happen in 5.7.0. Can upload a video to show you the comparison.

So it seems better on 5.7.0, but it doesn't match the 5.0.1 behavior - if that's the intention. If not (because gaining a bit of height as you keep bouncing on trampoline seems weird) then 312 might remain incompletable unless using an older client.

@ZenonSeth 5.7.0 made the shortcut in 312 possible subsequently making the box completable in that version.

Instead of jumping to the second trampoline you can jump to the last one which is in the floor. You'll have to thread the gap between the bars and the ledge on the way up. But you'll have just enough height to make it onto the marble ledge.

I don't have access to box 312 (or any others. the tutorial gives me unbearable motion sickness), but I want to mention MT 5.7 does allow accumulating bounce height (and decreasing, by the sneak key) but not at the same rate as MT<5.3 since it relied on broken collision in a way that makes correction impossible to quantify.

Box 184 "Crystalline Infection" has a problem as seen in the images. If you are too early close to the exit, you cannot go back. The steel trapdoor is not climbable. At this point you have to leave the box and restart.
