Keeping Unreal Engine and relevant plugins up to date is also important. Ensuring that the latest versions are used can provide fixes for known issues related to touch input and overall performance improvements.

6. Monitor Performance Metrics

Monitoring performance metrics using Unreal Engine's profiling tools helps identify and address performance bottlenecks that could contribute to delayed or unresponsive touch inputs.

7. Implement Logging for Touch Input Events

Implementing logging for touch input events helps track and analyze user interactions. This data can help identify patterns or recurring issues, facilitating more effective troubleshooting and optimization.

WebSocket Connectivity Issues

WebSocket technology is integral to Pixel Streaming, facilitating real-time, bidirectional communication between the server and client. However, developers often encounter connectivity challenges that can disrupt the streaming experience. Understanding these common issues and implementing effective troubleshooting steps are essential for maintaining a stable connection.

1. Frequent Disconnections

One prevalent issue is the occurrence of unexpected disconnections during streaming sessions. These interruptions can result from network instability, server overload, or misconfigured WebSocket settings. Such disruptions degrade the user experience and may necessitate manual reconnection.

2. Error Codes Like 1006

The WebSocket error code 1006 indicates an abnormal closure, often without a specific reason. This error can stem from various factors, including network interruptions, server-side issues, or client-side problems. Diagnosing the exact cause can be challenging due to the generic nature of this error code.

3. Delayed Responses

Users may experience latency or delayed responses during interactions, leading to a sluggish streaming experience. Such delays can result from high network latency, server performance issues, or inefficient handling of WebSocket messages.

Troubleshooting Steps
