Shake

Shake makes an object tremble on the spot: small, nervous movements in position plus a little roll, like something rattling, vibrating or scared.

How it works

The tremble is built from smooth noise rather than a new random position every frame, which would look like flicker. Each direction of movement and the roll follow their own noise track, so the shake feels organic and never repeats in a pattern. Its forward-and-back movement is half as strong as the rest, so most of the tremble shows up and down and side to side. It eases in when switched on and settles back still when switched off, and it is layered over the object's own position and animation, so it can shake while it floats or moves.

Settings

• Strength: how far it moves, as a share of its height.
• Rate: how many jitters per second; low is a slow rattle, high is a buzz.
• Roll: how far it tilts as it shakes.
• Duration: one pass of building up, shaking and settling; with Loop on it keeps shaking.

Use it for

"Wrong answer" or error feedback, alarms and phones ringing, rumbling engines, earthquakes, and nervous characters. Run it on click for a quick rattle (triggering again settles it), keep it on with Loop for a vibrating machine, or switch it on in an action. For a slower circular lean, use Wobble; for a hit followed by a rattle, Slam.
