AE Expression Code

// Inertial Bounce (After Effects) amp = 0.05; freq = 4.0; decay = 2.0; n = 0; if (numKeys > 0){ n = nearestKey(time).index; if (key(n).time > time){ n--; } } if (n == 0){ t = 0; } else{ t = time - key(n).time; } if (n > 0 && t < 1.0){ v = velocityAtTime(key(n).time - thisComp.frameDuration/10); value + v * amp * Math.sin(freq * t * 2 * Math.PI) / Math.exp(decay * t); } else { value; }

How To Apply Expressions

Open the Expression Editor

Option-Click (Mac) or Alt-Click (Windows) on the **Stopwatch icon** next to the desired property inside the After Effects timeline.

Paste the Code

Delete any auto-generated text in the expression box and paste the code copied from this playground.

Link Controller Sliders (Optional)

For custom parameters, add an **Expression Control > Slider Control** to your layer. You can pick-whip the values directly to automate sliders dynamically!

Slider Reference Snippet

Instead of hardcoding numbers, bind a parameter to a slider effect on a Null Object called `"Control"`:

amp = thisComp.layer("Control").effect("Amplitude Slider")("Slider"); freq = thisComp.layer("Control").effect("Frequency Slider")("Slider"); wiggle(freq, amp);

Troubleshooting Hints

Numeric Keypad Enter:To apply expressions, don't use standard Enter. Use the numeric keypad Enter key, or click outside the text box to execute.
