Blender_bevy_components_workflow/tools/bevy_components/TODO.md

Basics

• add panel

• add a "create blueprint" button

  • when clicked:
    • create collection
    • add an empty inside collection and name it <COLLECTION_NAME>_components
    • add a AutoExport Boolean property to collection
    • add name imput(popup for name input ?)

• add a list of existing components/custom properties

• add an "edit blueprint" section

  • only filled when there is ONE selection, and that selection is a collection
  • add a dropdown of possible components
  • add a checkbox for enabling disabling a component (enabled by default)
  • add a button for copying a component
  • add a button for pasting a component

UI:

• filterable list of components to DISPLAY for selection : ComponentDefinitionsList

• Filter out invalid objects for components that have no _components suffix ? (that is too limiting I think)

• -[x] How to deal with pre-existing custom properties that have NO metadata

  • if there is one without metadata: find if there is an available component with the same name & type ?
  • if there is , insert metadata
  • otherwise, mark it in some way visually ?

• for OBJECT enums: add two ui pieces

  • one for selecting the TYPE to choose (ie normal enum)
  • one for setting the VALUE inside that

• vecs => (not vec2, vec3 etc) more complex UI to add items in a list

  • generate contained CollectionGroup
  • CollectionProperty => type = the above

• find ways to "collapse" the different levels of nested data of structs/tupples into a single custom property (ideally on the fly, but we can do without)

• for single tupple components that represent a single unit type, re_use the base type's UIPropertyGroup instead of creating specific ones (ie TuppleTestF32_ui...) => will not work, would cause overriden "update callback"

• pre_generate default values/values for each main type

• fix issues with vec2 etc not having the correct number of items

• fix bad defaults in ui group

• fix object enums handling on updates (??)

• fix issues with lambads in loops

• object enum should be (params) ie *Collider: * Cuboid(Vec3) * Sphere(radius)

• deal with enums variants that do not have any data: ex { "long_name": "Mesh" }

• remove / change use of ComponentDefinitionsList

  • when filling the list, use the long_name as index ie items.append((str(index), item.name, item.long_name)) => items.append((item.long_name, item.name, item.long_name))

• when removing a component, reset the value of the attribute in the property group (or not ? could be a feature)

• deal correctly with fields of types that are NOT in the schema.json (for ex PlayingAnimation in AnimationPlayer)

• deal correctly with complex types CascadeShadowConfig: has an array/list ClusterConfig: one of the enum variants is an object

• possibly allow Color to be an enum as it should be ?

• for sub items , the update functions "Name" should be the one of the root object

• fix copy & pasting

  • it actually works, but the value of the custom property are not copied back to the UI, need to implement property_group_value_from_custom_property_value

• we need a notion of "root propertyGroup" =?

• notify user of missing entries in schema (ie , unregistered data types)

• clarify propgroup_ui vs named nested fields

• fix basic enums handling

• add a list of not found components to the registry, add to them on the fly

• add configuration panel (open the first time, closed on further user once configured)

• add limits to ixxx types vs utypes

• only display the "generate components xx" when relevant ie:

  • go through list of custom properties in current object
    • if one does not have metadata and / or propgroup: break

• remove custom property of disabled component ? => NOpe, as we need custom properties to iterate over

• what to do with components with n/a fields ? perhaps disable the component ? add a "invalid" field to meta ?

• format output as correct RON

  • fix issue with empty strings

• change custom property => propGroup to convert RON => Json first => obsolete

• cleanup process_lists

• fix issues with enum variants with only a long_name

• display single item enums inline, others in a seperate row

• add button to "apply all" (in configuration), to apply/update all custom properties to ALL objects where relevant

• add button to "apply to current" to do the same with current

• add warning sign to the above

• what about metadata ?

• only upgrade custom properties to metadata when asked/relevant

• implement move list up/down

• change property_group_value_from_custom_property_value => just disregard it for now, its point is very limited (helping people with old custom properties by attempting to generate real values) and give the change to a real ron format, it is too limiting

• fix reload registry clearing list of missing types

• clean up metadata module, a lot of repeated code

• some fields when original is 0 or 0.0 are not copyable ? (seems like a bad boolean check )

• fix issues with object variants in enums (see clusterconfig)

• perhaps directly export default values within the schema.json ? - for most types , it is straighforward, but others, not so much: like the default color in Bevy , etc

• change default schema.json to registry.json

• pasted components do not get updated value in custom_property

• finish documentation

• add storage of registry path

  • save after setting the data (browse for)
  • load after each reload ?

Additional

- [x] check if output "string" in custom properties are correct

- gltf_auto_export
    - [x] add support for "enabled" flag
    - [ ] add special components 
            - "AutoExport" => Needed
            - "Dynamic" ? naah wait that should be exported by the Bevy side
    - [x] filter out Components_meta ??
    - [x] add legacy mode to the persisted parameters

- bevy_gltf_components:
    - [x] first release patch for current issues
    - [x] make configurable 
    - [x] add "compatibility mode" and deprecation warnings for the current hack-ish conversion of fake ron
    - [x] update docs to show we need to use ComponentsFromGltfPlugin::default

- bevy_gltf_blueprints
    - [x] update dependency
    - [x] update version
    - [x] add ability to set legacy mode for bevy_gltf_components ? 

- [x] release all versions
- [x] update main documentation, add compatibility version grid

Phase 2

• fix handling of long component names

  • fix nesting level handling issue for new system : ie basic component DOES NOT work, but nestedLevel2 does
  • add goddam tests !
  • verify some weird prop => custom property values (Calculated Clip for example)

• fix "reload registry" not clearing all previous data (reloading registry does not seem to account for added/removed components in the registry )

• add file watcher for registry

  • have the watcher work as expected
  • add handling of removed registry file
  • clear & reset handler when the file browser for the registry is used

• re-enable watcher

• tests clear && pytest -svv --blender-executable <path_to_blender>/blender/blender-4.0.2-linux-x64/blender

  • load registry

  • just check list of components vs lists in registry

  • try adding all components

    • select an object
    • call the add_component operator

  • change params

    • use field names + component definitions to set values
    • find a way to shuffle params of ALL components based on a reliable, repeatable seed

  • test propgroup values => custom property values

  • test custom property value => propgroup value

  • check if all went well

• fix issues with incorect custom_property generation

  • fix issue with object variants for enums

• add handling for core::ops::Range & other ranges

• add handling for alloc::borrow::Cow

• add handling of isize

• indirection level

  • currently

    • short_name +_"ui => direct lookup
    • problem : max 64 chars for propertyGroupNames

  • possible solution

    • propertyGroupName storage: simple , incremented INT (call it propGroupId for ex)
    • lookup shortName => propGroupId

  • do a first pass, by replacing manual propGroupNames creation with a function

  • in a second pass, replace the innards

• add button to regenerate cutom prop values from custom properties (allows us to sidestep any future issues with internals changing)

  • fix lists
  • fix enums (see Clusterconfig)
    • need an example with one tupple one struct
    • projection
    • additionalmassproperties
  • fix tupleStructs (see TupleVecF32F32) => always the same problem of having us pre-parse data without knowing what we have inside
    • find a way to only split by level 0 (highest level) nesting "," seperators, ignoring any level of nesting until we dig one level deeper
    • solve nesting level use issues

• remove metadata when deleting components

• add try catch around custom_prop => propGroup

• enhance the GenerateComponent_From_custom_property_Operator to use the new system to actually generate the stuff

• coherence in operators:

  • component_name vs component_type
  • delete => remove

• clean up reloading of registry settings

• clean up file watcher

========================================= Restructuring of storage of components

• marking of invalid root propgroups/components should be based on long name

• overhaul & check each prop group type's use of short names => long names

  • lists

• property_name = short_name in process enum: will likely require to use another indirection helper to keep the propery names short

• in conversions from propgroups component_name = definition["short_name"]

• fix is_component_valid that is used in gltf_auto_export

• Hashmap Support

  • fix parsing of keys's type either on Bevy side (prefered, unlikely to be possible) or on the Blender side
  • handle missing types in registry for keys & values
