perf: generate user limb skins per limb instead of whole skins

View 5 more changes
  • User limbs used to cost 10 MineSkin uploads per skin per variant, even for limbs no loaded model used. Limbs are now uploaded on demand, and eager generation on join only covers the limb types that loaded blueprints reference.
  • - No limb[type=] bone loaded: 0 uploads per joining skin, was 10.
  • - Default skins: 0 uploads at startup, was 20. They fill in on first use.
  • - Head, body, arms and legs model: 5 uploads, was 10.
  • - A failed limb no longer discards the ones that succeeded, so a retry only re-sends what failed.

feat: sub-tick bone transform sampling

View 33 more changes
  • Opt in per bone, then read by index, where `0` is the previous tick and `n` is the current one.
  • ```java
  • bone.setSubTickSamples(10); // ancestors are raised to match
  • Transform t = bone.getSubTickTransform(k); // model space, like getGlobalTransform()
  • Matrix4f m = bone.getSubTickMatrix(k); // like getTransformMatrix()
  • Location loc = bone.getSubTickLocation(k);
  • Location eye = bone.getSubTickLocation(k, OffsetMode.LOCAL, new Vector3f(0, 0.2f, 0), true);
  • ```
  • Samples go through the animation's own interpolators, so curved segments and step keyframes resolve exactly as they do at tick resolution. `isSubTickStep(k)` marks where a step keyframe landed.
  • ```java
  • for (int k = 1; k <= 10; k++) {
  • var t = bone.getSubTickTransform(k);
  • if (bone.isSubTickStep(k)) camera.snapTo(t);
  • else camera.lerp(bone.getSubTickTransform(k - 1), t, frac);
  • }
  • ```
  • Everything returns `null` (`false` for the step flag) when sampling is off, the index is out of range, or the buffer has not been filled yet, so callers fall back to `getGlobalTransform()`.
  • ## API
  • | Method | Returns |
  • | --- | --- |
  • | `setSubTickSamples(int)` / `getSubTickSamples()` | opt in, `0` disables |
  • | `getSubTickTransform(int)` | `Transform`, model space |
  • | `getSubTickMatrix(int)` | `Matrix4f` |
  • | `getSubTickLocation(int)` | `Location` |
  • | `getSubTickLocation(int, OffsetMode, Vector3f, boolean)` | `Location` |
  • | `isSubTickStep(int)` | `boolean` |
  • ## Notes
  • Bones the animation does not fully drive (bone behaviors, manual animators, procedural transforms) are detected each tick by composing the animation alone and comparing it against what the tick produced. Those interpolate their own two tick transforms instead, which still lands exactly on the tick values at both ends.
  • Off by default at one null check per bone per tick. When on, `n + 1` animation evaluations and decomposes per opted-in bone per tick.
  • Supporting changes:
  • - `SubTickProperty`, a time-shifted read-only view of an `IAnimationProperty`
  • - `AnimationHandler.updateBone(bone, propertyMapper)`, whose default ignores the mapper so third-party handlers degrade to tick resolution instead of breaking
  • - `Transform.set`

perf: block culling does far less work per player

View 3 more changes
  • - Block culling used to build the full list of a model's box corners before testing any of them. It now walks the visible faces directly and stops at the first corner that is in view. Same culling decisions, a small fraction of the memory churn, so the cull thread and the GC both get lighter.
  • - Bone item updates got the same treatment on a smaller scale.
  • - Fixes models more than 16.7 million blocks from spawn being culled while still visible. The old corner math lost precision that far out and ended up skipping half its checks.

perf: skip repeated work in bone item and behaviour lookups

View 3 more changes
  • - Updating a bone's items copied a set that was already deduplicated, just to compare it against a set it could never match.
  • - On Java 21 and newer the copy is now skipped, making the update 14-48% faster when models spawn or change parts.
  • - Servers on Java 17 (1.19.4 to 1.20.4) keep the copy, since dropping it there would reorder a bone's sub-models.

perf: reduce per-entity overhead on the model tick

View 2 more changes
  • Every model does a few lookups per entity each tick to reach the entity behind it.
  • These took slower paths than they needed to, and one of them created a throwaway object on every call.

perf: send fewer bytes when a model comes into view

View 3 more changes
  • Trims redundant clientbound data from the spawn and tracking paths, cutting the traffic burst when a model enters view by roughly 10 to 30 percent.
  • Savings scale with start-tracking events rather than with viewers standing still.
  • Also fixes two client disconnects, one under Bundle-Everything and one on the held-item path.

fix: add inheritfaction option to bindHitbox

View 4 more changes
  • bindHitbox always copied the caster's faction onto the bound mob, silently overriding the faction set in the bound mob's own config.
  • This broke any faction-based targeting of bound mobs, e.g. keeping them alive with remove @children{targetconditions=[ - faction{f=x} false]}.
  • Set inheritfaction=false (alias: if) on the mechanic to make the bound mob keep its own faction.
  • Defaults to true, matching summon's inheritfaction, so existing setups are unchanged.

Initial 26.1 & 26.1.1 support

View 4 more changes
  • Known bugged feature:
  • - Core share player model works, but causes some items in inventory to not render. Mineskin player model still works though.
  • - If your model has elements that has out of bound UV (i.e. UV starts under 0 or ends above the texture size,) the model will render as error cube. Since it is a modeling error, a warning message would be implemented later
  • 26.1+ requires Java 25. If there are any issues please tell Taiyou (cuz I will be gone for the week)

fix: guard interpolation delay with per-player snapshot check

View 1 more changes
  • Move snapshot computation before the interpolation delay condition so DISPLAY_INTERPOLATION_DELAY is only sent when the player actually has stale transform data. Previously, the delay was added based on the bone-level dirty flag alone, before the per-player snapshot was even computed. Also adds missing empty entity data guard to v1_20_R4.
