How to Safely Call Unity API Functions from Non-Main Threads?

Use Unity API from other threads or call functions in the main thread

Question

In a separate thread, using Unity's socket API may cause errors, especially when updating the UI element from the sub -thread. Due to thread security problems, the Unity API calls performed from non -main threads will trigger abnormalities.

Solution

Call the Unity API

Implement the following steps:

Create a static

called

to store the operation that needs to be performed in the main thread.

1. Copy to the local list (actionQueuesUpdateFunc) and perform these operations. List<Action>
Create a loss -loss Boolean value (
2. ) to indicate when the function is operated to execute when the function is operated. actionQueuesUpdateFunc actionCopiedQueueUpdateFunc
Call the main thread function
3. noActionQueueToExecuteUpdateFunc Update The function to call the function from a separate thread:

or, pass the function as a parameter:

Operating corporation in the main thread

UnityThread.executeInUpdate(() =>
{
    // 在主线程中执行的代码
});

For the coroutine: <对于>

How to use <使用>

Action rot = Rotate;
UnityThread.executeInUpdate(rot);

void Rotate()
{
    // 函数代码
}

Initialize in <初> :

UnityThread.executeCoroutine(myCoroutine());

IEnumerator myCoroutine()
{
    // 协程代码
}

Execute the code in <执>:

1. Awake() Perform in <执>: UnityThread

UnityThread.initUnityThread();

Execute the code in <执>:
2. Update

UnityThread.executeInUpdate(() =>
{
    // Update 代码
});

Execute the code in <执>:

3. Update

Starting the coroutine:

Action rot = Rotate;
UnityThread.executeInUpdate(rot);

void Rotate()
{
    // 方法代码
}

4. LateUpdate Additional description <附>

In order to improve performance, if not needed, please comment

UnityThread.executeInLateUpdate(() =>
{
    // LateUpdate 代码
});

and

.
5. FixedUpdate This solution uses a single
instance for all scripts.

UnityThread.executeInFixedUpdate(() =>
{
    // FixedUpdate 代码
});
