.hide() / .show()

Hides or shows a stamp, text object, or circle. Here's a program that hides or shows a stamp, some text, and a circle every time you tap the screen.

c = circle(384,512,200,'pink') w = stamp('watermelon') t = text('watermelon',300,600) function tap() {   if (w.hidden) {     w.show()     t.show()     c.show()   } else {     w.hide()     t.hide()     c.hide()   } }

Note that hiding a stamp, text object, or circle does not delete it. Once you add an object, it never gets deleted unless you call reset().

Hidden stamps (whether they got that way via hide() or explode() or pop()) generally don't interact with the "world". For example, if you check for hit() vs. a hidden sprite, false will be returned.

This code will show text, because both stamps are visible and overlap.

a = stamp('apple') b = stamp('boy') if (a.hits(b)) {   text('they hit!',300,700) }

This will not show text, because one of the stamps is hidden, and therefore can't be "hit."

a = stamp('apple') b = stamp('boy') b.hide() if (a.hits(b)) {   text('they hit!',300,700) }
