Verifica Colisão- collideRectCircle is not defined

p5.js says: It seems that you may have accidentally written "i" instead of "PI" (on line 22 in ator.js [/ator.js:22:41]).

Please correct it to PI if you wish to use the constant from p5.js (http://p5js.org/reference/#/p5/PI) 

Quando carrego o jogo está dando esse erro.
