Black Iron Spine—the backbone of your games. Get Your BIS.

BIS RPG Action Bar is a customizable Unreal Engine 5.8 action-bar framework. Add the source-included plugin to a supported Win64 project and press Play to see a working 12-slot starter bar. The plugin handles presentation, input, layout, cooldown display, and action requests; connect those requests to your own abilities, items, or combat rules with Blueprint or C++.

KEY FEATURES

• Flexible bars: Configure multiple bars with horizontal, vertical, or grid layouts, 1–24 slots per bar, per-bar visibility, scale, slot size, spacing, labels, opacity, and cooldown presentation.

• Exact key chords: Plain and Shift, Control, Alt, or Command-modified versions of the same base key can be assigned separately. Keyboard and gamepad bindings are supported.

• Move and snap: Shift-drag the complete layout, move panes independently, snap nearby glass edges together, move attached panes as a group, and Alt-drag to detach a pane.

• Arrange actions: Drag supplied preview actions onto standalone slots, swap assignments, drag an assignment off the bar to clear it, and lock slots against accidental editing.

• Readable combat UI: Slot icons, keys, stack or charge counts, availability states, tooltips, radial cooldown wipes, and countdown text make action state clear.

• Saved layouts: Create, rename, switch, save, and delete named player profiles, and choose a startup default. Layouts, presentation, and standalone assignments can persist through Unreal SaveGame data.

• BIS appearance controls: Black-iron glass, bright white active borders, live scale and presentation controls, a separate Window Settings panel, and a bottom-right launcher.

• Integration: Optional Blueprint startup and action-request events are included. Advanced games can implement ABKActionProviderInterface to own actions, cooldowns, and mutations.

PRODUCT BOUNDARY

This product supplies action-bar UI and input/request plumbing. It does not include authoritative abilities, damage, healing, targeting, inventory, movement controls, or a hosted multiplayer economy. The twelve supplied preview actions demonstrate interface and cooldown behavior; they are not a combat system. Characters, weapons, environments, and effects shown in illustrative artwork are presentation context and are not included.

Supported build: Unreal Engine 5.8 on Win64. Validated with Unreal Engine 5.8.1. Full C++ source included. No third-party code or runtime dependencies.
