Execution process at runtime

On the run-time side （ Let's say C++ Version to illustrate ,C# Version is basically similar ）, The entire build can be updated through Workspace::Update() Function to execute , This function mainly includes two functions ：

• call DebugUpdate() Function to update some functions related to continuous and hot loading .
• according to m_bExecAgents To determine whether it is necessary to perform all Agent Example of btexec() function , It can be through the interface Workspace::SetIsExecAgents(bool bExecAgents) Yes m_bExecAgents Set it up .

The specific execution logic is shown in the following code ：

void Workspace::DebugUpdate()
{
    this->LogFrames();
    this->HandleRequests();

    if (this->GetAutoHotReload())
    {
        this->HotReload();
    }
}

void Workspace::Update()
{
    this->DebugUpdate();

    if (this->m_bExecAgents)
    {
        int contextId = -1;

        Context::execAgents(contextId);
    }
}

about C++ edition , The execution of the behavior tree can call behaviac::Workspace::GetInstance()->Update() To carry out all Agent Instance behavior tree , You can also call Agent The interface of btexec() To execute the behavior tree of a single instance .

among ,Workspace::Update() Will traverse all Agent Instance and execute btexec(), But in my own game , It may be necessary to do some... In one frame Agent Multiple calls btexec(), And others Agent Just call... Once , In this case, you need to call Agent::btexec(), Instead of uniform calls Workspace::Update().

Workspace::Update() Calling Agent::btexec() Before , Will check the Agent::IsActive() Is it true, If false, that btexec() It won't be called .

Besides , To support continuous and hot loading , Please make sure that the update function of your game calls DebugUpdate() function . If you have already called behaviac::Workspace::GetInstance()->Update(), Then there is no need to call DebugUpdate().

The above example code is C++, But for the C#, They all have the same name .

Particular attention ： about C# edition ,behaviac.Workspace.IsExecAgents Default to false.

• If you will behaviac.Workspace.IsExecAgents Set to true, Use behaviac.Workspace.Instance.Update() Centralized update ,Agent You don't need to call... For your own updates btexec() 了 .
• If you will behaviac.Workspace.IsExecAgents Set to false, Do not use behaviac.Workspace.Instance.Update() Centralized update ,Agent For your own updates, you need to call btexec() 了 .
