详细描述

Coordinates deterministic timeline transport with a transactional preview host.

The controller borrows services that must outlive it. It invokes no preview host callback while holding a lock and remains owner-thread-only.

在文件 ActionPreviewController.h 第 21 行定义.

构造及析构函数说明

◆ ActionPreviewController()

eve::editor::ActionPreviewController::ActionPreviewController ( ActionTimelineEditor &  editor,
action::IActionPreviewSink &  sink,
const action::IActionRootMotionSource *  rootMotion = nullptr 
)

Construct with a required presentation sink and optional root-motion provider.

在文件 ActionPreviewController.cpp 第 21 行定义.
