After Effects Expression Bounce Floor

The most popular bounce expression for after effects.

After effects expression bounce floor.

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. Add the following expression to the position property of the layer. Download the loop expression example here. After effects will interpolate the velocity of your layers movement to help determine how the bounce will work.

Download the project file. The math that goes into making this bounce expression is pretty darn nerdy. The expressions below are all covered in the tutorial above and you can simply copy paste them to your project. To achieve this animation.

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. Add keyframes to the position property of the layer you want to animate. If you re new to after effects we suggest to first watch our introduction and then come back for these expressions. The bounce expression is great because it only takes two keyframes to create a bounce.

Essentially inertial bounce creates a bouncing motion of any parameter from one keyframe to the next based on its velocity. 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. These are expressions i use in just about every project and i consider them to be incredible workflow enhancements. Creating bounce particles allow you to wo.
