Additions
- owo-ui components can use the new
inspectorDescriptorgetter to customize the text displayed below them when the inspector is active ReadViewandWriteViewhave new methods for getting/setting values in them using keyed Endecs
Fixes
ModDataLoadernow works properly in a development environment using split sources- The surface setter on
DropdownComponentnow correctly returns the dropdown
Fixes
- Labels with text that has an empty style no longer crash when clicked on
- Scissoring on draw contexts which have complex transforms should no longer incorrectly cut off content
Changes
- Ported to 1.21.9: Most features seem to work well from our limited testing, however full library coverage is not guaranteed. Please report any problems you find
- The
zIndexproperty of owo-ui components has been removed - it has been nonfunctional since 1.21.6
Add AT entry for simple map of DataComponentMap to resolve crashing
Attempt to resolve issues with client side loading of classes and methods leading to crashes
Fix issues with MergedComponentMapMixin At targets due to not being remapped
Changes
- (Breaking) Renamed
OwoItemGroup.getBackgroundTexturetogetOwoBackgroundTextureto avoid a naming conflict when developing in an environment with Mojang Mappings
Fixes
DerivedComponentMapshould play more nicely with other mods that manually check for component equality- owo-ui blur no longer flickers occasionally
- owo-ui scissoring no longer incorrectly stops rendering elements that are partially off-screen. This is most noticeable in scroll containers, like the one used in owo config
This release is primarily a port to 1.21.6/7. Due to the massive vanilla refactors around GUI rendering in particular, this is a larger-than-usual update and we expect there will be some bugs and porting mistakes - please report anything you find!
Changes
OwoBlurRendererhas been replaced withBlurQuadElementRenderStatein accordance with the vanilla GUI rendering changes
Removed
(Block|Entity|Item)RegistryContainerOwoItemSettings, replaced by interface injection onItem.SettingsDraggableContainer.alwaysOnTopCodecUtils.ofEndec, replaced bytoCodecConfigScreen.(registerProvider|getProvider|forEachProvider), replaced byConfigScreenProviders
Fixes:
- Issues where flashing occurred with owo blur renderer
- Incorrect scissoring behavior leading to non rendering gui elements particularly with scroll containers in owo configs.
- Proper fix for
DerivedComponentMapequality - Fix possible issues with Optional reading and writing within NBT losing references due to use of
IdentityHolder
Neoforge
Changes to how classes persist due to the removal of @OnlyIn could lead to issues but mostly taken care of.
Update attempts to remove dependency on FFAPI to resolve issues, fix missing owo item groups, and pull from upstream 1.21.1, and fix issues with optional serialization issues

Initial port of owolib 0.12.21 for Neoforge
Fixes
- The blur pipeline now uses a custom vertex shader to avoid a random fog code dependency
OwoBlurRenderernow uses the depth buffer in its render pass to fix blur rendering issues on some drivers- owo no longer accidentally overwrites the vanilla
gui_texturedrender pipeline
Fixes
- Fixed the optional flattening implementation introduced in the last build
- Decoding of sequence elements in NBT has been made idempotent
Changes
- Updated to 1.21.5
- As a consequence of the changes to Minecraft's rendering backend, the
GlProgramAPI has been removed since it is no longer necessary - As a further consequence of the above change, owo's built-in programs have changed API:
OwoClient.HSV_PROGRAMhas been superseded byOwoUIPipelines.GUI_HSVOwoClient.BLUR_PROGRAMhas been replaced with theOwoBlurRenderer, which uses the same shader and parameters under the hood
Fixes
- Backport optional flattening fixes from 0.12.17
Fixes:
- Fix issues with errors relating to texture identifier being null
- Fix issue involved with ModDataLoader on Connector not being able to get any mod list
