How Can UnityThread Solve Cross-Thread Access Issues in Unity?

UnityThread

Many developers encounter problems when trying to access the Unity API function from threads other than the main thread. This may cause errors, such as "getComponentfastPath can only be called from the main thread."

Traditional methods and its limitations

The traditional method of solving this problem includes the use of Boolean variables to notify the main thread or uses corporation instead of threads. However, these methods have their limitations because they do not provide real thread security and lack the flexibility of multiple threads that need to notify the main thread.

Thread security solution: Unitythread

In order to overcome these restrictions, a thread security solution called UnityThread has been developed. It uses a collection to store the operation that needs to be performed in the main thread. Then copy these operations to the local list, execute and remove to prevent other threads from waiting. The working principle of the work of unitythread

UnityThread script has three main functions to perform operations in UPDATE, LateUpdate, and Fixedupdate. Each function has its own operating queue and an easy -to -loss Boolean variable to indicate whether there is an operation to execute.

When the operation is added to the operating queue, the Boolean variable is set to false, indicating that the operation is waiting for execution. In the Update, Lateupdate, or FIXEDUPDATE function, if the Boolean variable is true, the operation of the queue is copied to the local operation list and executed.

Using the use of unitythread

To use unityThread, first initiate it by calling unityThread.Initythread () to initialize it. Then, to execute the code in the main thread, use unityThread.executeinUpdate (() = & GT; {}); To call the function in the main thread, create an Action object and pass it to the ExecuteInUpdate function.

UnityThread also provides functions for executing operations in LateupDate and Fixedupdate and starting coroutines in the main thread. The advantages of unitythread

UnityThread is a reliable and thread security solution for accessing the Unity API function from other threads. It allows multiple threads to notify the main thread without causing errors or performance problems. In addition, it provides which functions are specified in the main thread and when they execute their flexibility.
