Time manipulation, and a real centaur

The headline is a new system: time runs at whatever speed you say, for a single entity, a chunk or a whole dimension, without a second mod in the pack.

Tick rates are an Apoli type now

Minecraft has had /tick since 1.20.3, but only for the whole server. Apoli 1.67.0 takes the same idea and lets you aim it. An entity, the chunk under a block, or a whole dimension can each carry their own rate, and the three fall back to each other: an entity with no rate of its own takes its chunk's, and a chunk takes its dimension's.

There are five new types, all sharing the name:

• apoli:modify_tick_rate is the power. It applies its state again every tick and lets it lapse when the power stops, so nothing stays frozen after a death, a revoke or a /reload. target: area slows or freezes everything around the holder.
• apoli:tick_rate and the block action are the one-shot form, with rate, frozen, step, sprint, reset and duration.
• apoli:tick_rate and the block condition read the effective rate back.

A slowed chunk covers block entities, scheduled block and fluid ticks, and random ticks, so a bubble of stopped time stops furnaces and crops as well as mobs. Rates never run anything faster than the server's own tick rate. To speed the world up, raise it with vanilla /tick rate and hold everything else down with a power.

    "type": "apoli:modify_tick_rate",
    "target": "area",
    "radius": 8,
    "shape": "sphere",
    "frozen": true,
    "affect_chunks": true,
    "condition": { "type": "apoli:sneaking" }
}

The centaur is a centaur

apoli:centaur used to be a pose: a seated rider, meant for sitting on someone else's avatar. It's now an actual centaur. The player's own head, torso and arms sit on a four-legged horse body with a mane and a tail, the player's legs are hidden, and the horse's legs trot along with the player's real movement.

The horse half is drawn from its own texture, a plain 64 × 64 horse skin at apoli:textures/entity/centaur/horse.png, so any horse texture drops straight in, either for everyone through a resource pack or for one power with the new model_texture_location field on apoli:modify_player_model. Every horse part can be named (horse_body, horse_tail, front_left_leg and the rest, plus horse_legs and horse) from modify_model_parts, model_color and custom_model_render.

Custom particles where a shot lands

apoli:spawn_particles is now a block action too, so a raycast's block_action and a projectile's block_action_on_hit can spawn an Apoli custom particle at the impact, which /particle through a command could never do. Its anchor defaults to hit, which uses the exact impact point instead of the block's centre.

Expressions in two more places

distance on apoli:grab is worked out again every tick, so an expression can reel the held target in and out while the grab is running.

roll and roll_speed on a custom particle are worked out once per particle, which is what you want them for:

"roll": "rUni(0, 360)",
"roll_speed": "rNor(0, 4)"

Every particle in the burst starts at its own angle and tumbles at its own rate.

Smaller things

• The apoli:fire_projectile action now honours interval and start_delay like the power does, and its page finally lists the fields it always shared with the power: offset_x, offset_y, offset_z, space, max_distance and shooter_action.
• origins: resolves to apoli: even without the Origins mod installed. A single type ID that can't be resolved anywhere inside a power's entity_action drops the whole action, so a pack written with origins: IDs used to go quietly dead on a server with only Apoli. It doesn't any more.
