In-Depth Information
This will now move the particle emitter to the location of the mouse cursor. If you want to remove the
pointer, add this line to the
love.load
function:
love.mouse.setVisible(false)
As shown in Figure
11-11
, this creates a particle emitter that spews particles. You can play with
the various
setGravity
values; for example, a negative number will make the particles float. You can
also play with
setSize
to make the particles bigger or smaller, and
setColor
to change the color of
the particles.

Tip
If you want to visually create particle effects, there is an application written in LÖVE that allows
for interactive particle creation. It can be found at

Physics
Box2D is the common thread across all of these frameworks when it comes to physics. As
mentioned earlier, Box2D is a very complex and large library. While some frameworks wrap and offer
a few functions to work with the library, LÖVE offers developers complete access, so there are a
couple of extra steps involved to create a physics body.
