double_vision

type: "double_vision"

Two ghost copies of the frame offset left/right with a slow drift.

Fields

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

Field	Type	Default	Meaning
offset	float	0.04	Ghost distance from the centre, screen-width fractions (0..0.5)
ghost_opacity	float	0.5	Ghost opacity (0..1)
drift	float	0	Slow sinusoidal drift, screen fractions per second (0..0.2)
intensity	float	1 (fades to 0)	Overall strength (0..1)

Example

{
    "type": "double_vision",
    "duration": 60,
    "params": { "offset": 0.04, "ghost_opacity": 0.5, "drift": 0, "intensity": 1 }
