Custom status effects, and four more

Apoli 1.95.0 is a feature release, built on work contributed by FLDebug10 and PolarKookie.

Custom status effects

A file in data/<namespace>/effects/ now defines a real status effect. It works with /effect give, potions, apoli:apply_effect and apoli:status_effect, and while an entity has it, the entity holds the powers the file lists:

{
    "type": "beneficial",
    "powers": ["example:frenzy_speed"],
    "r": 0.85, "g": 0.15, "b": 0.1,
    "name": "Frenzy"
}

The server sends the list to every client, so players only need a resource pack for icons and translations. Server owners can switch the whole feature off in config/apoli-effects.json. Everything else is on the Custom status effects page.

/resource operation and /execute store resource

/resource operation combines a resource with a scoreboard score, using the same operators as /scoreboard players operation, down to its rounding and its "Cannot divide by zero" error:

resource operation @s example:mana += @s mana_bonus

resource is also a target for /execute store now, and it chains with the other store clauses the way store score does:

execute store result resource @s example:mana run data get entity @s XpLevel

Both are on the Resource command page.

Three new types

• apoli:sprinting makes the player sprint whenever they move forward.
• apoli:cooldown, an item action, puts the item on cooldown, like an ender pearl after a throw.
• apoli:aggro_at, a bi-entity action, makes a neutral mob angry at a player.

Update both sides

This release changes the network protocol, so the server and every player need Apoli 1.95.0, and a client on an older version can't join.
