Growing the branches

- [Instructor] Hi, this is the last video of this section,…Growing the Branches.…In the previous video, we looked at getting started…with functions.…In this video, we are going to take a look at preparing,…updating, drawing, and moving the branches.…Now, as I've been promising for around the last…few videos, we'll use all the new C++ techniques…to draw and move some branches on our tree.…Add this code outside the main function.…Just to be absolutely clear, I mean before the code.…We just achieved quite a few things with that new code.…

First, we wrote a function prototype for our function…called updateBranches.…We can see that it does not return a value,…and it takes an int argument called seed.…We will write the function definition soon, and we will then…see exactly what it does.…Next, we declare a constant int called NUM_BRANCHES,…and initialize it to six.…There will be six moving branches on the tree,…and we will soon see how NUM_BRANCHES will be useful to us.…Follow this.…We declare an array of sprite objects called branches…
