[SPZ2-4839] [1.0.0-RC2] the floating shape problem

[sturdy kayak]

when i was testing the shapes, i notice that half destroy the right side shape will produce a floating shape
is it intentional design or not

Bug with crystals in falling quadrants in stacker and cutter
Done • Priority: Highest • Fix: 4.1 - EA Prototype • Resolution: Done

When stacking a shape with a crystal in a quadrant that should break and fall, the crystal quadrant incorrectly stays floating on the upper layer instead of falling to the lower layer. This occurs when stacking shapes where the support breaks, such as stacking CgcbCy-- on top of Cr------. The Cy quadrant should fall to layer 1 when cb breaks, but it remains floating on layer 2. The same bug happens when cutting certain shapes with the Signal Producer. This has been fixed and the crystal quadr...

Cutters do not follow stacking rules and create floating shapes
Done • Priority: Medium • Fix: None • Resolution: Won't Fix

When a shape is cut that has a layer with only a west half, the cutter does not follow stacking rules and creates floating shapes. The affected layer appears invisible after cutting, causing the shape to float improperly. This issue is easier to reproduce in Insane difficulty using the specific shape code provided. The expected behavior is that cutters should follow stacker logic when destroying a layer, preventing floating shapes from being created.

Crystal quadrant sticks to shape quadrant on layer below
Done • Priority: Medium • Fix: 4 - Early Access • Resolution: Done

A Crystal quarter was incorrectly sticking to a regular Shape Quarter on the layer below it, preventing the upper piece from falling as it should. When the same shape was built without the Crystal, the unsupported quarter would fall correctly. The expected behavior is that Crystals should only stick to other Crystals, not to regular shape pieces. This has been verified as fixed, so unsupported non-crystal quarters now fall properly even when crystals are present elsewhere in the shape.

[Dev] Cutter breaks when cutting shapes where one half is empty
Done • Priority: High • Fix: 2 - Demo • Resolution: Done

The Cutter and Half Cutter machines break when attempting to cut shapes where one half is already empty. This occurs when a shape that has already been cut is fed into a Cutter, which tries to cut the remaining half, resulting in nothing. The machine fails to handle this edge case properly. This issue has been verified as fixed in the master branch.

Half Destroyer doesn't shatter connected crystal.
Done • Priority: High • Fix: 4 - Early Access • Resolution: Done

The Half Cutter does not shatter connected crystals as expected. When a single layered crystal on the right side is connected to a three layered crystal on the left side, with pins placed prior to crystallization, the crystals on layer 3 are not connected vertically to other crystals. The machine fails to properly break apart the crystal structure during the cutting operation. This prevents correct processing of crystallized shapes with support pins.

it's a bug ( https://discord.com/channels/1000343719314198548/1397501456109535442 )

[sturdy kayak]

why it showed "won't fix"🤔

[fringe pulsar]

at some point there was a misunderstanding on what the issue was, so the report was classified as won't fix, maybe the status wasn't updated properly

[full frost]

And @fringe pulsar It was set to Won't Fix, because it was determined too risky to attempt to change the shape logic.

I wonder, too risky before 1.0 or too risky in general ?

[raven sierra]

Most likely in general - not saying we're never gonna fix it, but changing a single line in the shape logic means we need to test a lot to make sure we didn't break anything else, esp. also advanced crystal mechanics etc 😅

The folks in #1295099125016301608 are willing and able to test any shape logic changes.
