P5play

P5play is a P5.js library developed originally by Paolo Pedercini that makes it easier to make games. Version 3 is led by Quinton Ashley.

P5.js, which we looked at in class, will still be useful for a few things. But mostly we'll be using P5play for the game stuff.

This library will help you handle sprites and animation, groups of objects, collisions, and simple physics, 

Getting Started Resources

With p5play and OpenProcessing you can build games!

• p5play homepage
• p5play reference page (which can be a bit overwhelming)

Enabling P5play in your Projects

If you get an error It seems that you may have accidentally written "Canvas" instead of "noCanvas" you forgot to toggle P5play on.
