Members & coop

Island roles (Owner, Coop, Trusted, Member, Banned), permissions, flags, presets, entity caps, and island settings.

Updated 11d ago

Your island is not a solo affair. Invite friends as coop partners, trusted players, or members. Manage who can do what, toggle island flags to control gameplay behaviour, and customize your island's look and feel.

In short

Islands support up to 16 members across 5 roles. Use island flags to control gameplay behaviour, and customize settings like biome, weather, border color, and entity caps.

Member roles

Every island supports up to 16 members (hard cap, all bonuses included). There are 5 roles, ranked from highest to lowest:

Role	Build / break	Interact / buckets	Bank access	Upgrades	Invite others	Settings
Owner	Yes	Yes	Yes	Yes	Yes	Full
Coop (Co-owner)	Yes	Yes	Yes	Flag-gated	No	No
Trusted	Yes	Yes	Flag-gated	Flag-gated	No	No
Member	No (visitor-level)	No	No	No	No	No
Banned	No (cannot enter)	No	No	No	No	No

Member role is restrictive

Members are treated like visitors by default. They cannot build, break, interact, or access the bank. To give someone building rights, assign them the Trusted or Coop role instead.

Key details:

Coop is the co-owner role. There is no separate "Co-owner" rank. Coop players always have full bank access.
Trusted bank access depends on the BANK_ACCESS island flag. If the flag is off, Trusted players cannot deposit or withdraw.
Trusted and Coop upgrade access depends on the UPGRADE_ACCESS island flag.
Member cannot build or break blocks. The canBuild() check explicitly excludes Members. They are essentially visitors with a label.
Two flags exist in the GUI but do nothing in code: MEMBERS_CAN_INVITE and COOP_CAN_EDIT_FLAGS. They are shown in the flag editor but are never checked by the invite or flag-editing handlers.

Your maximum coop slots increase as you climb progression rank tiers (from 3 at tier 1 up to 15 at tier 9).

Inviting and managing players

Action	Command
Invite a player	`/island invite <player> [role]`
Accept an invitation	`/island accept`
Deny an invitation	`/island deny`
Add a member directly	`/island add <player> [role]`
Remove a member	`/island remove <player>`
Promote a member	`/island rank promote <player>`
Demote a member	`/island rank demote <player>`
Set a specific role	`/island rank set <player> <role>`
Transfer ownership	`/island transfer <player>`
View all members	`/island members`

Ownership transfer is permanent

Transferring ownership hands full control to another member. You become a regular member. This cannot be undone without the new owner's cooperation.

Visitors and bans

Any player can visit your island if it is set to public. Toggle visibility with /island privacy.

Action	Command
Toggle public / private	`/island privacy`
Expel a visitor to spawn	`/island expel <player>`
Ban a player from visiting	`/island ban <player>`
Unban a player	`/island unban <player>`
View your ban list	`/island banlist`

Island flags

Flags are per-island boolean toggles that control gameplay behaviour. Open the flag editor with /island flag or browse by category with /island flag list. Flags are organized into 9 categories:

Category	Controls
Combat	PvP, friendly fire, damage sources
Mobs	Mob behaviour, aggression, targeting
Mob Spawn	Which mob types can spawn on your island
Nature	Crop growth, water flow, fire spread, ice melt
Explosions	Creeper, TNT, bed, and other explosion damage
Visitors	What visitors can and cannot do (build, use chests, interact)
World	Block physics, redstone, leaf decay, weather effects
Permissions	Member-level overrides (BANK_ACCESS, UPGRADE_ACCESS, and others)
Premium	Rank-gated flags (see below)

You can also set or check individual flags by command:

Action	Command
View all flags by category	`/island flag list`
Check one flag's value	`/island flag get <flag>`
Set a flag	`/island flag set <flag> true/false`
Reset a flag to default	`/island flag reset <flag>`

Flag presets

Instead of toggling flags one by one, apply a curated bundle that configures multiple flags at once:

Preset	Best for
Peaceful	No hostile mobs, no PvP, no explosions
Public Hub	Visitors welcome, building restricted, safe environment
PvP Event	Full PvP enabled, explosions on, competitive settings
Grind	Optimized for mob farming and XP grinding
Farm	Optimized for crop growth and passive automation
Vanilla	Default Minecraft behaviour, minimal protection

/island preset list
/island preset apply <preset>

Premium flags (rank-gated)

Cosmetic ranks unlock premium flags that give your island additional protections and quality-of-life toggles. These are cumulative: a higher rank includes everything from the ranks below it.

Rank	Flags unlocked
Sentinel	Permanent saturation, no phantom aggro
Void	Infinite water source, auto crop replant, keep potion effects, enhanced spawner rates
Shadow	10 damage immunities: fall, fire, drowning, suffocation, freeze, hunger depletion, starvation, thorns, falling block, cramming
Dragon	6 more immunities: lightning, contact, poison, magic, dragon breath, kinetic
Mythic	Void damage, wither effect, sonic boom + boss/mob spawn flags (warden, evoker, ravager, boss)

Flags can also be bought individually

Some premium flags can be purchased with Coins from the island bank, even without owning the rank. Common mob-spawn flags cost 50,000 Coins, dangerous ones 100,000.

Entity caps

Your island has limits on how many entities can exist at once. Base caps can be increased through rank bonuses and upgrades:

Category	Base	Hard cap	Rank bonus per tier	Upgrade step	Upgrade cost
Animals	20	60	+3	+5	25,000 Coins
Monsters	30	80	+4	+8	15,000 Coins
Villagers	6	24	+1	+2	50,000 Coins

Entities over your cap are auto-removed after a 5-minute grace period. Manage caps with /island caps and trim excess entities immediately with /island caps trim.
