BUG: Wrong Resource Path #147
Description
PROBLEM DESCRIPTION
The resource_path() function in EyeTrackApp/utils/misc_utils.py fails to correctly resolve asset file paths in development mode, causing FileNotFoundError when launching overlay programs that depend on resources like Purple_Dot.png.
ROOT CAUSE
The function uses Path(".") as the base path in development mode, which resolves relative to the current working directory (project root). However, actual resources are located in the EyeTrackApp/ subdirectory, making relative paths fail when the application is launched from the project root.
Example:
- Current working directory:
C:\Users\...\EyeTrackVR-copy\ - Resource location:
C:\Users\...\EyeTrackVR-copy\EyeTrackApp\Tools\assets\Purple_Dot.png - Resolved path:
.\tools\assets\Purple_Dot.png❌ (relative to project root, notEyeTrackApp)
REQUESTED INFORMATION

- Searched the problem in issues
- Searched the problem in discussions
TO REPRODUCE
- Clone the repository
- Run from project root:
poetry run .\EyeTrackApp\eyetrackapp.py - Tracking mode
- Observe error:
C:\Users\Administrator\Documents\OpenSourceProject\EyeTrackVR-copy> poetry run .\EyeTrackApp\eyetrackapp.py
