BounceEaseIn()

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

inlinestaticconstexpr

Bounce ease-in interpolation for reverse bouncing ball effect.

Implements bouncing by reversing BounceEaseOut. Creates a series of bounces that converge to the start.

The motion consists of four phases in reverse:

• Small initial bounces (10% of time)
• Medium bounce (18% of time)
• Large bounce (36% of time)
• Final launch (36% of time)

Common uses:

• Object launches
• UI element takeoffs
• Character jump startup
• Power-up activation

Parameters

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

Returns

Eased value

Note

Reverses BounceEaseOut for symmetric animations
