error that locked my browser
I apologize for the error that locked your browser. Let's create a more optimized version of the animation player that won't cause performance issues.
I'll rebuild the animation player with performance as a priority:
I've completely rebuilt the animation player with several key optimizations to prevent browser lockups:
Added three performance levels (high, medium, low) that adjust:
This implementation should run smoothly without locking up your browser, while still providing the core functionality of a three.js animation player with sequencing, parameter controls, and multi-layer compositing.
I see the error in your Three.js Animation Player. The error message "TypeError: undefined is not an object (evaluating 'a.count')" indicates there's an issue with accessing the count property of an undefined variable a.
This is likely happening in one of the animation components, specifically when trying to access the buffer attributes of a geometry. Let me fix this issue:
The error you're seeing (TypeError: undefined is not an object (evaluating 'a.count')) occurs when the code tries to access properties of an object that doesn't exist yet. This typically happens during the animation rendering process when:
These changes should prevent the error from occurring by ensuring we only try to access properties when the objects actually exist. The error boundary we added previously will also catch any remaining issues and prevent the entire application from crashing.
The code returns the following error:
Uncaught error: TypeError: undefined is not an object (evaluating 'a.count')
Revise the code to address the error.
