Updated to 1.21.1
Fixes
- Fixed some bugs that emerged from version 1.2.2
Additions
- You can now fire spawn eggs from cannons. This might cause unexpected issues, use at your own risk!
Thanks Nacolla and Ninni for the help!
Updates
- Added a dynamic software-based rendering system to ensure Hullback's damaged armor renders correctly with OptiFine and Oculus shaders.
- Replaced vanilla movement wrappers with custom stationary-aware controls for smoother behavior.
- Implemented full compatibility with Neat health bar mod.
- Added new configuration options to scale and dynamically offset UI heights based on the Hullback size.
- Tweaked Hullback physics and mechanics for a smoother experience:
- Improved riding timers for better dismount logic and player detection.
- Added hysteresis to platform spawning to prevent rapid snapping when hovering on the edge.
- Adjusted proportional buoyancy and water seeking for a smoother resting depth.
- Changed Walkable Platforms to use fluid interpolation instead of hard hitbox snapping.
- Dynamically altered player detection bounding boxes based on approach states.
- Cleaned up the codebase by removing unused classes, obsolete rendering types, and dead tracking files.
- Added a new server-side config allowing customization of fields such as:
- Hullback's spawn frequency(Chance based)
- Hullback's spawn cap
- Hullback's despawn time(tick based) including
- A multiplier to said time
- A grace radius around the Hullback that pauses the despawn timer in case the player is inside it.
- Debug settings for:
- Hullback buoyancy system:
- Height on water for:
- Wild Hullbacks
- Tamed Hullbacks:
- While stationary
- While sailing(when player sits on the helm)
- Height on water for:
- Hullback buoyancy system:
- Refactored the barnacle dirt placement system.
- Made it so widgets such as sails and cannons can be placed on the ground.
- Interacting with the sails by right clicking them will make them rotate.
- Right click: 11,25 degrees to the left
- Shift + Right click: 11,25 degrees to the right
- Interacting with the sails by right clicking them will make them rotate.
Fixes
- Fixed major visual glitches where damaged armor planks would break depth tests when shaders were active.
- Fixed a critical detachment bug where attached widgets would detach from the Hullback sometimes upon joining a world(through exaustive tests, the possible cause was an forced/improper shutdown of the game)
- Fixed a terrestrial speed bug where the Hullback would move at extreme aquatic speeds while stranded on land.
- Fixed the desynchronization of the Hullback's swimming animation and the Helm's wheel rotation when being controlled.
- Before it would only be shown to the one controlling it, now both sides will be able to see it.
- Fixed innacurate player movement when riding a mast attached to the Hullback's tail.
- Fixed visual z-axis rotation for passengers while the Hullback is being controlled.
beta 1.2.1
Hullback
- Made walking hitboxes a bit wider
- Made sound travel distance configurable
Ship Mechanic
- Modded heads now render correctly in the crown slot
- Fully armored hullback now renders as cutout to avoid flickering while clipping through the entity in spectator mode
Sail
- Banners now drop when sails are broken
beta 1.2.0
Hullback
Fixed walking on hullback mechanic
- it now goes completely still and creates invisible platforms for players, avoiding jitteriness
Ship Mechanic
The ship can now be equipped with all types of vanilla planks
- If the item's block hardness is proportional to the armor's chance to fully negate attacks
- More armor block types can be added simply by adding them to the "items/hullback_equippable" item tag and providing a texture in "whaleborne\textures\entity\armor" using a resourcepack
- Make sure the file is named correctly, hullback_<block_id>_armor.png
- Example: for "acacia_planks", the texture would be named "hullback_acacia_planks_armor.png"
Cannon
New interaction with boat and chest boat items is now possible
Sail
Sails can now be interacted with with a banner to apply its patterns to the sail
- Using a waterbucket on the banner sail will drop the banner
Anchor
Anchors can now be placed on blocks, right clicked or shift right clicked to change its facing angle
- Punching them will drop the anchor item again
Rough Barnacles
Using an axe on a hullback will now drop rough barnacles, a new decorative block that can be stacked up to three times in one block space Using two rough barnacles in a crafting grid will give you a barnacle, which can be stacked up to 9 blocks high to create organ like musical notes
Shader incompatibility
Added a new client config to address the shader incompatibility
beta 1.1.1
Hullback
Hullbacks now has a wandering cooldown when a passenger hops off Hullbacks are much less likely to spawn in cave aquifers
Ship Mechanic
Fixed disappearing equipment bug Fixed relogging desync Fixed equipment rotation issues Other fixes
Cannon
Removed fire charge temporarily
Helm
If anchors are present on the hullback, pressing space while on the helm will lower / raise them
Reuploaded to fix NoSuchFields crash
beta 1.1.0
Hullback
- Hullbacks now turn less violently when player is holding a temp item
- Hullbacks will now seek water when beached
Ship Mechanic
- Fully overhauled seating system to make it more reliable

- Added FOV zoom when steering in F5 mode
Mast
- Using a leashed mob on a mast now deposits it on top, right click the mast to drop the mob
Cannon
- Added more sound events
- Now drops content on death
- Using a barnacle as ammo now has a special interaction
Barnacles
- Barnacles now individually react to redstone signal

Initial Release!
