Flips the frame horizontally and/or vertically.
|
|
Can be used for mirror effects or beat-triggered flips.
|
|
|
|
@param horizontal bool
|
|
@default false
|
|
Flip horizontally (left-right mirror).
|
|
|
|
@param vertical bool
|
|
@default false
|
|
Flip vertically (top-bottom mirror).
|
|
|
|
@example
|
|
(effect flip :horizontal true)
|
|
|
|
@example
|
|
(effect flip :vertical true)
