Detailed Description

Deki Engine timing system.

Provides platform-independent timing functionality for the engine. All time values are in milliseconds for consistency.

Member Function Documentation

Initialize()

void DekiTime::Initialize ( )

static

Initialize the timing system Should be called once at engine startup.

GetTime()

uint32_t DekiTime::GetTime ( )

static

Get current time in milliseconds.

Returns

Current time since initialization in milliseconds

GetElapsed()

uint32_t DekiTime::GetElapsed ( uint32_t previous_time )

static

Get elapsed time since a previous timestamp.

Parameters

previous_time

Previous time value from GetTime()

Returns

Elapsed time in milliseconds

Update()

void DekiTime::Update ( uint32_t deltaTime )

static

Update the timing system Should be called once per frame.

Parameters

deltaTime

Frame delta time in milliseconds

GetDeltaTime()

uint32_t DekiTime::GetDeltaTime ( )

static

Get the last frame delta time.

Returns

Delta time of last frame in milliseconds

GetDeltaTimeF()

float DekiTime::GetDeltaTimeF ( )

static

Get the last frame delta time as float (high precision).

Returns

Delta time of last frame in milliseconds with sub-ms precision

UpdateF()

void DekiTime::UpdateF ( float delta_time_ms )

static

Update with float delta time for high precision (used by editor FPS limiter).

Parameters

delta_time_ms

Frame delta time in milliseconds (float for sub-ms precision)

GetFPS()

float DekiTime::GetFPS ( )

static

Get frames per second.

Returns

Current FPS

ResetFrameTime()

void DekiTime::ResetFrameTime ( )

static

Reset frame time after loading Call after loading a scene to prevent huge deltaTime from accumulated loading time.

SetDelayFunction()

void DekiTime::SetDelayFunction ( std::function< void(uint32_t)> fn )

static

Register the platform-specific sleep implementation.

Called during platform init before RunMainLoop begins.

Delay()

void DekiTime::Delay ( uint32_t ms )

static

Sleep for ms milliseconds using the registered delay function.

No-op if no function has been registered.

SetTimeProvider()

void DekiTime::SetTimeProvider ( std::unique_ptr< ITimeProvider > provider )

static

Set the platform-specific time provider.

Must be called before Initialize().

Parameters

provider

The time provider implementation (takes ownership)
