Free After Effects Project: 2D Aim Constraint with Expressions (Chetal Gazdar)
Original title: How to Create a 2D Aim Constraint in After Effects Using Expressions: Tutorial and Project File
Overview
Chetal Gazdar provides this free After Effects project file with his tutorial on creating a 2D aim constraint using expressions and simple trigonometry. The technique aligns one layer to another based on their relative positions, which suits objects that need to follow or aim at specific targets.
The 75 KB MediaFire zip (2D_aim_constraint.zip) holds two 'aim Constraint start' .aep files and a butterfly PSD, and downloads free with no signup; the version is not stated.
What You Can Learn
- Use trigonometry inside an expression to point one layer at another
- Align a layer to a target from the two layers’ relative positions
- Rig objects that follow or aim at a moving target
