InteractPrompt Pro

InteractPrompt Pro provides a lightweight hover-prompt system for Unity using a simple and reliable detection model:

1. Raycast-based Hover Detection

Each frame, the system casts a ray from the camera through the mouse position.
If the ray hits an object that has a HoverPrompt component (or a parent with one), that object becomes the current hover target.

2. Max Distance Filtering

You can define a maximum detection distance.
Objects beyond this range won’t show prompts.

3. LayerMask Filtering

Only objects on the selected layers will be considered hoverable, allowing fine control over what should show prompts.

4. Shared On-Screen UI

A single UI element displays the prompt.
It smoothly fades in when hovering a valid object and fades out when nothing is hovered.

5. Per-Object Content

Each interactable object can define:

• A prompt text (e.g. “Inspect”, “Open Chest”, “Interact”)

• An optional icon (keyboard key, mouse button, custom graphic)

InteractPrompt Pro focuses purely on visibility of prompts — it does not trigger gameplay actions or handle interaction keys.
This gives you full freedom to implement your own interaction system alongside it.
