readd(obj: GameObj): void

Remove and re-add the game obj, without triggering add / destroy events.
// Common way to use this is to have one sprite overlap another sprite, and use readd() to have the bottom sprite on top of the other.

// Create two sprites.
const greenBean = add([
    sprite("bean"),
    pos(200,140),
    color(255, 255, 255),
    area(),
]);

// This bean will overlap the green bean.
const purpleBean = add([
    sprite("bean"),
    pos(230,140),
    color(255, 0, 255),
    area(),
]);

// Example 1: simply call readd() on the target you want on top.
readd(greenBean);

// Example 2: using onClick() or other functions with readd().
// If you comment out the first example, and use this readd() with a function like onClick(), you
can keep switching which sprite is above the other ( click on edge of face ).

purpleBean.onClick(() => {
    readd(greenBean)
});

greenBean.onClick(() => {
    readd(purpleBean)
});
