(A)

Peasycam has beginHUD

See Peasycam documentation

[http://mrfeinberg.com/peasycam/reference/index.html](http://mrfeinberg.com/peasycam/reference/index.html)

(B) make a invisible PGraphics pg that you draw your stuff on but each with a unique color that you store. When mouse is pressed use pg.get() to retrieve the color of the position. Look up the index of the item that has this color. It’s a picking technique.

`(C)` you can temporarily deactivate Peasycam, I think with cam.setActive(false);

Use lights(); - looks much better
