## プロパティ

- `Stats.ContactsCount: int`：A measurement of how many parts are currently in contact with one another.
- `Stats.DataReceiveKbps: float`：In a networked game, this describes roughly how many kilobytes of data are being received by the current instance, per second.
- `Stats.DataSendKbps: float`：In a networked game, this describes roughly how many kilobytes of data are being sent by the current instance, per second.
- `Stats.FrameTime: float`：A measurement of how long it takes for the engine to process all tasks required to render a frame.
- `Stats.HeartbeatTime: float`：A measurement of the total amount of time it takes for the server to update its task scheduler jobs in seconds.
- `Stats.InstanceCount: int`：A measurement of how many Instance are currently in memory.
- `Stats.MemoryTrackingEnabled: boolean`：An indication of whether memory tracking is enabled. This is guaranteed to be unchanged until the next time the Client is started.
- `Stats.MovingPrimitivesCount: int`：A measurement of how many physically simulated components are currently moving in the game world.
- `Stats.PhysicsReceiveKbps: float`：In a networked game, this describes roughly how many kilobytes of physics data are being received by the current instance, per second.
- `Stats.PhysicsSendKbps: float`：In a networked game, this describes roughly how many kilobytes of physics data are being sent by the current instance, per second.
- `Stats.PhysicsStepTime: float`：A measurement of how long it takes for the physics engine to update its current state.
- `Stats.PrimitivesCount: int`：A measurement of how many physically simulated components currently exist in the game world.
- `Stats.RenderCPUFrameTime: float`：A measurement of how long it takes for the CPU to process all of its rendering tasks for a frame.
- `Stats.RenderGPUFrameTime: float`：A measurement of how long it takes for the GPU to process all of its tasks required to render a frame.
- `Stats.SceneDrawcallCount: int`：A measurement of the number of draw calls made by the game's current scene.
- `Stats.SceneTriangleCount: int`：A measurement of the number of triangles rendered by the game's current scene.
- `Stats.ShadowsDrawcallCount: int`：A measurement of the number of draw calls being made for shadows by the game's current scene.
- `Stats.ShadowsTriangleCount: int`：A measurement of the number of triangles rendered as shadows in the game's current scene.
- `Stats.UI2DDrawcallCount: int`：A measurement of the number of 2D draw calls made for UI elements in the game's current scene.
- `Stats.UI2DTriangleCount: int`：A measurement of the number of triangles that are being rendered for 2D UI elements in the game's current scene.
- `Stats.UI3DDrawcallCount: int`：A measurement of the number of 3D draw calls made for UI elements in the game's current scene.
- `Stats.UI3DTriangleCount: int`：A measurement of the number of triangles being rendered for 3D UI elements in the game's current scene.

## メソッド

- `Stats:GetHarmonyQualityLevel(): int`：Internal-only. Returns the engine's current dynamic-quality level as a score normalized from 0 to 100.
- `Stats:GetMemoryCategoryNames(): Array`：Internal-only. Returns an array of the names of every developer memory category the engine tracks.
- `Stats:GetMemoryUsageMbAllCategories(): Array`：Returns the number of megabytes that are being consumed by all available categories, or an empty array if Class.Stats.MemoryTrackingEnabled|MemoryTrackingEnabled is false.
- `Stats:GetMemoryUsageMbForTag(tag: DeveloperMemoryTag): float`：Returns the number of megabytes that are being consumed in the specified DeveloperMemoryTag category, or 0 if Class.Stats.MemoryTrackingEnabled|MemoryTrackingEnabled is false.
- `Stats:GetTotalMemoryUsageMb(): float`：Returns the total amount of memory being consumed by the current game session, in megabytes.
- `Stats:ResetHarmonyMemoryTarget(): ()`：Internal-only. Restores the performance-control system's memory budget to the values in effect before Class.Stats:SetHarmonyMemoryTarget() was called.
- `Stats:SetHarmonyMemoryTarget(targetMB: int): ()`：Internal-only. Overrides the performance-control system's memory budget with a target value, in megabytes, for testing.
