What is Control Flow?

The Control Flow of a program is the order in which the program's code executes.
As a competent programmer, you NEED to understand where you are in the Control Flow and where it can lead you.
📌 By default, your program will execute instructions in a linear order, executing each line of code after the next.
📌 This linear flow can be broken up using conditional statements and function calls.
📌 It's easy to represent the Control Flow of your program using a graph.
📌 If using GCC, you can use tools like Trucov to print the Control Flow of your program.
📌 The If-Statement and Switch-Statement will cause your Control Flow to branch.
📌 Loops will cause your Control Flow to go back to a previous node.
📌 Function calls will jump to an entirely separate part of your control flow.
✅ When you are writing lines of code, you are defining the Control Flow of your program.
✅ Where it can branch, loop, jump, break; essentially what it can do and where it can go.
✅ The cool thing about the Control Flow is that you don't have to understand the entire graph at once.
✅ The graph can be broken up or "encapsulated" into a single section.
✅ This makes it easier for us to understand; that's why we separate code into different functions and classes.
🎮 In Unity, you can think of the entire Control Flow as a huge massive graph.
🎮 But we only need to worry about the Control Flow in our own MonoBehaviors. ➡️ Follow @mefirstgames for more game dev tips.
