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

<code class="language-csharp">UnityThread.executeInUpdate(() =>
{
    // 在主线程中执行的代码
});</code>

For the coroutine:

How to use

<code class="language-csharp">Action rot = Rotate;
UnityThread.executeInUpdate(rot);

void Rotate()
{
    // 函数代码
}</code>

Initialize in :

<code class="language-csharp">UnityThread.executeCoroutine(myCoroutine());

IEnumerator myCoroutine()
{
    // 协程代码
}</code>

Execute the code in :

1. Awake() Perform in : UnityThread

<code class="language-csharp">UnityThread.initUnityThread();</code>

Execute the code in :
2. Update

<code class="language-csharp">UnityThread.executeInUpdate(() =>
{
    // Update 代码
});</code>

Execute the code in :

3. Update

Starting the coroutine:

<code class="language-csharp">Action rot = Rotate;
UnityThread.executeInUpdate(rot);

void Rotate()
{
    // 方法代码
}</code>

4. LateUpdate Additional description

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

<code class="language-csharp">UnityThread.executeInLateUpdate(() =>
{
    // LateUpdate 代码
});</code>

and

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

<code class="language-csharp">UnityThread.executeInFixedUpdate(() =>
{
    // FixedUpdate 代码
});</code>
