Interface ILunyTimeService

Namespace

Luny.Engine.Services

Assembly

Luny.dll

Provides engine-agnostic access to time and frame information.

public interface ILunyTimeService : ILunyEngineService

Remarks

IMPORTANT: Implementations must inherit from both the ILunyService interface and its corresponding LunyServiceBase class!

Properties

DeltaTime

Time since last frame update. Updates once after heartbeat. Value varies with framerate.

double DeltaTime { get; }

Property Value

double

Remarks

When read in a Heartbeat method, be aware that DeltaTime is last frame's deltaTime.

ElapsedSeconds

Gets the time in seconds since the application started. Uses real time (not affected by Time.timeScale).

double ElapsedSeconds { get; }

Property Value

double

EngineFrameCount

Gets the engine's frame count since the application started.

long EngineFrameCount { get; }

Property Value

long

Remarks

CAUTION: This value may differ between engines! Some engines start with frame 0, others in frame 1. Unity for instance launches in frame 0 where it runs Awake and OnEnable, but by Start it has incremented FrameCount to 1. While in Godot the entire first frame's FrameCount is 0. Prefer FrameCount since it is the same for all engines.

FixedDeltaTime

Time between two heartbeats. Value remains fixed (constant) at runtime.

double FixedDeltaTime { get; }

Property Value

double

FrameCount

Gets the total number of frames LunyEngine has run since launch. This value is consistent across engines.

long FrameCount { get; }

Property Value

long

Remarks

Initialization (startup, OnCreate, OnEnable) occurs in FrameCount 0. By OnReady (and before first OnHeartbeat/OnFrame) FrameCount will be 1.

HeartbeatCount

Gets the total number of heartbeats LunyEngine has run since launch. This value is consistent across engines.

long HeartbeatCount { get; }

Property Value

long
