Sync

<table><tr><td width="900">

MonsterDB includes full server synchronization support so all clients stay consistent with the server's configuration.

| Step | Description | |:---|:---| | Game Load | Plugin starts and reads all files from the Import folder | | Server | Loads imported files, creates clones, and applies all updates | | Client | Waits for files from the server, then creates clones and applies updates | | FileWatcher | If enabled, any changes made on the server are automatically sent to all connected clients |


</td></tr></table>


RRR

<table><tr><td width="900">

To convert RRR.json files into MDB.yml files, install https://thunderstore.io/c/valheim/p/ValheimModding/JsonDotNET/ to gain access to command: monsterdb rrr which will look for files within folder RRR at BepInEx/config/MonsterDB/RRR

RRR Converter was designed to parse both RRR.json and DropThat.cfg to coalesce into MDB.yml

Notes

  • Not all RRR values are transfered over, i.e (cTintColor, cTintItems, cBodySmoke)
  • Recommended to review exported files and clean up fields ( fields that do not change any values )

List of fields not copied:

- dtAttackDamageOverride
- fAttackDamageTotalOverride
- sAttackProjectileOverride
- cTintColor
- cTintItems
- cBodySmoke
- bAttackPlayerObjectsWhenAlerted
- fHairValueMin
- fHairValueMax
- bCanTame
- bAlwaysTame
- bCanProcreateWhenTame
- bFxNoTame
- bSfxNoAlert
- bSfxNoIdle
