InteractAPI

InteractAPI

A lightweight library for customizable world-space interaction prompts and quick time events.

InteractAPI provides a display layer for other mods to render floating interaction icons, key prompts, and interactive QTE sequences directly in the world.

Quick Time Events

InteractAPI also includes a built-in QTE system for creating interactive sequences and button-mashing challenges.

• Mash Events - Repeatedly press a key to fill a progress meter before time runs out.
• Sequence Events - Press a series of displayed keys before their timers expire.
• Arcade Style - Bright effects, animations, sound effects, and rewarding feedback.
• Horror Style - Darkened visuals, heartbeat effects, screen distortion, and increasingly intense feedback.
• Custom Results - Receive success, failure, cancellation, score, hit counts, and timing information.

Accessibility

Players can customize QTE difficulty through client settings:

• Hold instead of repeatedly mashing a key
• Increase event duration with a time multiplier
• Automatically complete QTEs

Designed for Developers

InteractAPI is a rendering and presentation library. It intentionally does not decide when an interaction should happen.

For ordinary prompts, InteractAPI:

• Does not read key presses
• Does not perform raycasts
• Does not activate blocks or entities
• Does not send network packets
• Does not determine whether a target is interactable

Your mod handles all interaction logic and tells InteractAPI when and where to display a prompt.

The API supports persistent and temporary prompts, reusable prompt IDs, dynamic anchors, and thread-safe registration.

QTEs are a separate feature that handle their own input during an active event and return the result to your mod.
