DeltaMilliseconds()

const Math::Types::Fxp & SRL::Timer::DeltaMilliseconds ( )

inlinestaticnoexcept

Frame delta time in milliseconds (fixed-point 16.16).

Pre-calculated each frame by Core::Synchronize(). Represents the time elapsed between frames in milliseconds with higher resolution than seconds.

Range:

• Typical 60fps: ~16.7 milliseconds
• Typical 30fps: ~33.3 milliseconds
• Fxp limit: 32767 milliseconds (~32.8 seconds)

Usage:

Use when you need millisecond precision for short-duration events, input debouncing, or animation keyframe timing.

// Check if enough time has passed for input repeat
if (Timer::DeltaMilliseconds().As<int>() > 100) {  // 100ms elapsed
    // Process repeating input
}

Warning

The 32767ms limit (~32.8s) is the Fxp format limit. The hardware timer itself can track up to ~673 days (PHI_128). For measuring longer durations than 32.8s, use DeltaSeconds() instead.
