Comprehensive Stopwatch & Countdown Timer

OBS Lua Comprehensive Stopwatch & Countdown Timer 3.7

Added new Feature:

1) Timer Cycle List for Source/Scene

Cycle Scene List: (used with Source Dock)


Cycle Source List: (used with Source Dock)



'Next Scene' option that activates when timer ends now include a new option to define either a "source list" or "scene list" that will have an infinate cycle. Everytime the timer ends it will reset and switch to the next item restarting the timer. To stop the cycle the timer needs to be stopped. This can be done with a hotkey.

Note: To work with sources, the sources should be nested in a group and the "group name" must be listed in the Source Toggler. This is required so that only the source needed is visible.

This feature is useful for someone who would like to set a timer that will cycle through scenes or sources, for example if you have several different cameras and would like to cycle through them at a specific interval.

Important: The list have to be manually entered and will only work if the source name was correctly defined.

2) Show Current Source Name

There is also a new text source config, that if selected, will show the source/scene name for the current active source/scene.

3) Some minor bug fixes
* Fixed Hotkeys for Script Duplication
* Fixed Media Play to complete when timer ended
* Fixed Looped Media Playback limitation
* Updated fix for User Common FPS (Used to calculate the Stopwatch Milliseconds)
