BounceEaseOut()

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

inlinestaticconstexpr

Bounce ease-out interpolation for bouncing ball effect.

Implements bouncing using piecewise quadratic functions. Simulates diminishing bounces of an elastic ball.

The motion consists of four phases:

• Initial fall (36% of time)
• First bounce (36% of time)
• Second bounce (18% of time)
• Final small bounces (10% of time)

Common uses:

• Dropping objects
• UI element landings
• Character jump landing
• Button clicks

Parameters

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

Returns

Eased value

Note

Each bounce is approximately 75% the height of previous
