After Effects Expression Bounce Floor

To achieve this animation.

After effects expression bounce floor.

The bounce happens in whatever direction the object is traveling. Download the project file. Copy the standard bounce expression for after effects. Http bit ly 2t89vxn learn how to create bounce particles that bounce off a floor in after effects.

The most popular bounce expression for after effects. Note that you also have to define the maximum number of bounces nmax to keep the expression from disappearing into an endless calculation of smaller and smaller bounces. The expressions below are all covered in the tutorial above and you can simply copy paste them to your project. Creating bounce particles allow you to wo.

The math that goes into making this bounce expression is pretty darn nerdy. Create or import your graphics in after effects. The loop expression is probably to most used after effects expression it allows you to repeat your animation forever with code tweak you can also control the loop time and repetitions. Essentially inertial bounce creates a bouncing motion of any parameter from one keyframe to the next based on its velocity.

These are expressions i use in just about every project and i consider them to be incredible workflow enhancements. The bounce expression is great because it only takes two keyframes to create a bounce. First create an animation ie. After effects will interpolate the velocity of your layers movement to help determine how the bounce will work.

The bounce parameters launch angle elev initial velocity v elasticity e friction f and gravity g are all defined at the top of the expression. Download the loop expression example here. Download the ae presets. Scale 100 to 120 or position from left to right.
