EaseOut()

static constexpr Fxp SRL::Math::Interpolation::EaseOut ( const Fxp & start, const Fxp & end, const Fxp & t )

inlinestaticconstexpr

Quadratic ease-out interpolation for decelerating motion.

Implements quadratic easing using the formula: -t * (t - 2)

The easing produces this motion:

• Starts at full velocity
• Continuously decelerates
• Stops smoothly (zero velocity)

Common uses:

• Character movement stop
• UI element exit
• Zoom-out effects
• Landing animations

Parameters

start	Starting value of the interpolation
end	Ending value of the interpolation
t	Interpolation factor in range [0,1]

Returns

Eased value

Note

For symmetric animation, pair with EaseIn
