moving object(words)

hardbrain · October 2016

hello, I'm studying for my project with the leap motion and processing. It's my first time to do programming, I'm trying to mix up some of sketches i found and to change little bit. based on https://www.openprocessing.org/collection/2560

whatever, Here is my Question.

how to change WordPaint axis? It moves to the left around the edges. 1-1. how to make to move WordPaint automatically on Y axis only? (wants to move like BBQ)
Wants to limit space. move inside on 'size'
