//FLICKER OPACITY blinkSpeed =10; n = Math.sin(time*blinkSpeed); if (n<=0) 0 else 100; This After Effects expression is intended to create a flickering effect by adjusting the opacity of a layer over time. Here’s how it works: In summary, this expression creates a flickering effect by modulating the opacity of a layer based on a sine […]
//OSCILLATE POSITION BACK AND FOURTH ON X AXIS: amplitude = 10; frequency = 3; temp=amplitude*Math.sin(time*frequency)+amplitude; // add the result to the current x pos temp=temp+transform.position[0]; //plug the new x into slot 0. y is currently left unchanged [temp, transform.position[1]]
//MAKE A LAYER BOUNCE: bounceSpeed=7; flight=01; bounceHeight=3.5; t=Math.abs((time*2*bounceSpeed)%2-1); t=linear(t,flight,0,0,1); b=Math.cos(t*Math.PI/2); value – [0,bounceHeight*b]; This After Effects expression is designed to create a bouncing animation effect for a layer. Let’s go through it step by step: In summary, this expression creates a bouncing animation effect for a layer based on the current time. Adjusting the variables […]
To create an After Effects expression that flickers an object’s opacity to 100%, you can use the wiggle() function to generate random flickering and then gradually increase the opacity. Here’s an expression that achieves this effect: // Adjust this flicker frequency to your taste var flickerFrequency = 5;// Generate flickering effect var flicker = wiggle(flickerFrequency, […]
