After Effects Expression Bounce Floor

Http bit ly 2t89vxn learn how to create bounce particles that bounce off a floor in after effects.

After effects expression bounce floor.

The most popular bounce expression for after effects. After effects will interpolate the velocity of your layers movement to help determine how the bounce will work. 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. Create or import your graphics in after effects.

First create an animation ie. The bounce happens in whatever direction the object is traveling. To achieve this animation. Scale 100 to 120 or position from left to right.

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. Download the loop expression example here. If you re new to after effects we suggest to first watch our introduction and then come back for these expressions. Download the ae presets.

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. Creating bounce particles allow you to wo. The bounce expression is great because it only takes two keyframes to create a bounce.

The math that goes into making this bounce expression is pretty darn nerdy. Add the following expression to the position property of the layer. Copy the standard bounce expression for after effects. 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.
