input.json

Describes the button input mappings shown in the Core Settings > Controls menu. Currently read-only.

Per-Asset Functionality

Default

By default, the Controls menu is loaded from:
/Cores/AuthorName.CoreName/input.json

It is possible to have completely unique Controls 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 input.json.

A per-asset Controls menu, if it exists, is loaded from:
/Presets/AuthorName.CoreName/Input/<path_to_slot0_asset>.json

Example

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/Input/myplatform/common/subfolder1/asset.json
