slice_shift

type: "slice_shift"

The frame is cut by a straight line and the halves slide past each other along it; the exposed strips at the screen edges are filled with wrapped or mirrored copies of the world (no black gap).

Fields

Every screen effect also accepts screen_layer and the shared definition fields (duration, easing, loop, persistent, fade_ticks, sound).

Field	Type	Default	Meaning
angle	float	0	Cut-line tilt in degrees from horizontal (0 = horizontal line, 90 = vertical)
offset	float	0	Pushes the line off the screen centre along its normal, in screen fractions (-0.5..0.5)
shift	float	0.05 (fades to 0)	How far each half slides along the line, in screen fractions; halves diverge by 2x shift, negative swaps the sides (-1..1)
mirror	float	0	Fill of the exposed strips: 0 = repeat/wrap, 1 = mirrored copy
