Describes any custom UI elements to be displayed in the Core Settings menu.
The Core Settings menu is built up dynamically from the following sources:
input.json)data.json, any data slot marked as “User-reloadable” in its Parameter Bitmapinteract.json file.Up to 16 UI entries from interact.json can be shown. However, if more than 4 reloadable data slots are also present, additional entries will be dropped to maintain a maximum of 20 combined interact+data menu entries.
It is recommended to use list items since each one can have up to 16 of its own possible options within itself, and does not count towards the overall limit.
See the data.json section for an explanation on what happens when a user reloads a data slot through this menu - the behavior can be customized.
The following UI elements are supported:
checkradioslider_u32listactionnumber_u32Each frame, all of the UI elements are read back from the core at a specified 32-bit BRIDGE address, updated with new user-adjusted values, and finally written back. This read-modify-write cycle requires the core to have both read and write support at each desired address, unless the element is flagged as writeonly .
Elements with a mask can be used to selectively modify any number of bits in a register. The readback value where the mask bits are set will be preserved when writing back.
If any persistent elements are found and loaded, they will be written into the core’s register space on boot immediately before the APF sends the [0011 Reset Exit] host command.
Persistent values will be saved out by their ID. If you update your core to add or remove some interact elements, APF will try to match up all the settings by their ID, so all IDs should be unique.
By default, the interact menu is loaded from:/Cores/AuthorName.CoreName/Interact/interact.json
By default, the interact menu’s persistent values are saved to:/Settings/AuthorName.CoreName/Interact/interact_persist.json
It is possible to have completely unique interact menus for every single primary asset loaded by the core. APF will check in a specific location, generated from the very first data slot 0. If it is found, it will override the core’s existing interact.json.
A per-asset interact menu, if it exists, is loaded from:/Presets/AuthorName.CoreName/Interact/<path_to_slot0_asset>.json
A per-asset interact menu, if it exists, will save persistent values to:/Settings/AuthorName.CoreName/Interact/<path_to_slot0_asset>.json
For example, with an primary asset loaded into data slot 0 with current path and filename of/Assets/myplatform/common/subfolder1/asset.bin
APF will check for a JSON file mirroring the same folder structure, but in a different base folder:/Presets/AuthorName.CoreName/Interact/myplatform/common/subfolder1/asset.json
Similarly, any persistent values will be saved to:/Settings/AuthorName.CoreName/Interact/myplatform/common/subfolder1/asset.json

writeonly: boolean
If present and true, the value will only be stored in JSON and written to the core, but never read back from the core. Optional.
defaultval: integer / hex string
Initial value. May be 0 (unchecked) or 1 (checked). Restored when user selects Reset to Defaults.
value: integer / hex string

value_off: integer / hex string
Value that is written when unchecked. Optional. Defaults to 0.
mask: integer / hex string
