Drifting Snow

This recipe shows how to use the TriplePlay particle system to simulate snowflakes drifting down the screen, with random "wind" that blows them about. Note: the TriplePlay particle system requires WebGL and therefor so does this recipe.

Live Demo

Controls

• None - just sit back and relax

Source Code

• Snow.java

Exercises

• Make the rotation vary for different particles. You probably don't want to compute a sin/cos for every single particle, but you could compute five or six of them and assign them to particles based on their index.
• Make the "wind" vary for different particles. Either choose a different velocity scale factory based on the particle's current y position, or some other differentiating factor.
