I live in Berlin, where I studied Biology but then discovered that CGs are fun. The two programs I use the most are Blender and After Effects and now I am quite eager share my knowledge with the world.
In Part 4 and Part 5 of this tutorial you will learn how to apply effects and expressions to existing layers using Javascript. The result is designed to handle large numbers of pictures with a randomly created offset, so that they form a wall when the created slider is 0 and disperse in Z-space when increasing the slider value. The script will also have a user interface, so you can use it on any number of layers, without changing the source code.

In Part 3 of this series, we’ll be learning how the Adobe Javascript Editor works and how to write a script that can be executed in After Effects. You will learn how to debug scripts and end up with just a few lines of code that will generate a cube that consists of 1.000 solids, a parent null object, a light and a camera.

This is the second tutorial on the road to generating script files for After Effects. I read the comments from Part 1 stating that those are expressions, not actual Javascripts. I figured, to learn what Javascript does from scratch, you have to understand expressions first, because you can immediately see what the changes do. There will be one more tutorial on placing layers with expressions, then we’ll move on to actual scripts. In this tutorial you will learn how for-loops can help analyzing several frames in order to customize effects.

This series of tutorials will get you closer to the world of variables and case-by-case analysis. The introduction to Javascript will start with After Effects expressions and continue on to writing scripts that build an entire scene. Expressions and Scripts are used to automate values that would take a long time to keyframe or building scenes containing a lot of similar elements, with a few lines of code.
