Props · `RandomBars`

Changes apply to the demo above and to the code tabs. Descriptions come from the library registry (MIT).

Name	Value	Default	Range / options	Description
`progress`Progress	0.5Auto-animated in the demo — moving it pins the value	0.5	0 – 1 (step 0.01)	How far the wipe has progressed (0 = fully visible, 1 = fully wiped away)
`angle`Angle	0	0	0 – 360 (step 1)	Orientation of the bars in degrees (0 = vertical bars)
`barCount`Bars	12	12	2 – 100 (step 1)	Number of bars across the frame
`softness`Softness	0.15	0.15	0 – 1 (step 0.01)	How softly each bar fades out (0 = hard-edged bars)
`invert`Invert		false	—	Reverse the order the bars vanish in

Every component also takes blendMode · opacity · visible · maskSource/maskType · boundingBox · id

Bars across the frame disappear one after another in a varying order. It adds an unpredictable sequence to a regular stripe pattern.

`progress` defaults to 0.5 and ranges from 0 to 1. `angle` defaults to 0 degrees and ranges from 0 to 360 degrees to rotate the bars. `barCount` defaults to 12 and ranges from 2 to 100 for their number; `softness` defaults to 0.15 and ranges from 0 to 1 to soften each fade. `invert` defaults to false and reverses the order.

Place it over an image or video, and put the next scene on a lower layer for a transition. Many bars can fragment the frame and feel busy; low softness makes hard edges, so tune it to the size and contrast of the content.

When to use

Use it for a transition with an irregular bar rhythm, a short video cut, or striped graphics. Avoid it when the frame should feel calm or long copy must stay intact.
