DeltaMinutes()

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

inlinestaticnoexcept

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

Pre-calculated each frame by Core::Synchronize(). Represents the time elapsed since the previous frame with minute precision.

Precision and Range:

• Hardware precision: ~4.47μs per tick (PHI_128)
• Fxp precision: ~0.9ms per unit (16.16 format)
• Fxp limit: 32767 minutes (~22.7 days)

Usage:

Use for long-term game timers, auto-save intervals, session tracking, and any timing that spans minutes to days.

// Auto-save every 5 minutes of gameplay
static Fxp gameTime = 0;
gameTime = gameTime + Timer::DeltaMinutes();
if (gameTime > 5.0) {
    SaveGame();
    gameTime = 0;
}

Note

DeltaMinutes provides the longest range among delta variables while maintaining fixed-point precision. Ideal for persistent game state.
