We are still creating five sprites in
initTestObjects()
as before. The difference is
that we are now using the bunny head, feather, and gold coin texture regions. To
make our test a little bit more interesting, we create a dynamic array called
regions
that holds all the texture regions we want to use. Then, inside the setup loop, we
create a
Sprite
instance with a randomly picked texture region from the dynamic
array. This results in a random number of similar looking objects in the test scene.
You can now run the game to test it out. The following is a screenshot that shows a
possible outcome due to the randomness that we built in:
