GAM220 at Southern New Hampshire University builds on the programming foundations from GAM110, which the catalog lists as the prerequisite. The description focuses on code fundamentals, optimization techniques and scalable software architecture.
Students learn to manage memory efficiently, write modular and maintainable code, and work within an integrated development environment. The leap from "it runs" to "it is well built" is what makes the course demanding.

What GAM220 Covers
| Topic (from the catalog) | What it means in practice |
|---|---|
| Code fundamentals | Data types, logic and clean structure |
| Optimization techniques | Finding bottlenecks and reducing wasted work |
| Scalable architecture | Organizing code so it can grow without becoming tangled |
| Memory management | Allocating, using and releasing memory safely |
| Modular, maintainable code | Small, focused units with clear responsibilities |
| Object-oriented design | Extensibility and reuse through well-chosen classes |
| Debugging in an IDE | Breakpoints, watches and step-through |
Key Concepts Explained
Measure Before Optimizing
Optimizing guesses wastes time. Profile first, find the slowest part, change it and measure again.
Example: A scene slows down with many enemies. Profiling shows the distance check runs against every object each frame. Checking only nearby objects (for instance, by grid cell) cuts the work, and a second measurement confirms the gain.
Ownership of Memory
Every allocation needs a clear owner and a clear end of life. Leaks and dangling references are common in game code that creates and removes objects often.
Example: Bullets are created every shot. Reusing a pool of bullets rather than creating and deleting each one reduces allocations and avoids leaks.
Modularity
Give each class one job and keep dependencies few. A change to input handling should not require edits in the renderer.
Refactoring Checklist
Improving code without changing what it does is a skill in itself. Use a checklist so each pass has a purpose.
| Smell | Likely fix | Check afterwards |
|---|---|---|
| A function longer than a screen | Extract smaller functions with clear names | Same output as before |
| Copied code in several places | Move to one shared function or base class | All callers still work |
| A class that knows about everything | Split responsibilities | Fewer dependencies per class |
| Magic numbers | Name them as constants | Values are easy to tune |
Typical Assignments and How to Approach Them
| Assignment type | What it tests | How to approach it |
|---|---|---|
| Feature implementation | Applying OOP to a spec | Design classes first, then code |
| Optimization task | Measured improvement | Record before and after figures |
| Memory exercise | Safe allocation and release | Draw who owns each object |
| Refactoring | Maintainability | Change structure without changing behavior; retest |
Reading a Profile Report
Optimization work is only convincing when it is measured. A short table of before and after figures makes the improvement visible and gives the marker something to check.
| Measure | Before | After | What changed |
|---|---|---|---|
| Frame time (illustrative) | Slow with many objects | Steadier | Distance checks limited to nearby objects |
| Allocations per second | High | Low | Object pool replaces create and delete |
| Update function length | One large function | Several focused functions | Refactoring for readability |
Use your own recorded figures in assignments; the rows above only show the layout. Always say how you measured, on what machine and with how many objects, so the result can be repeated.
A Worked Example: Reusing Objects
Allocation costs add up when a game creates and destroys many short-lived objects. A simple pool shows several course themes at once: memory, performance and modular design.
Example: Instead of creating a new bullet each shot, the game creates 50 bullets at start-up and marks each active or inactive. Firing activates an inactive bullet and sets its position; when it leaves the screen it is marked inactive again. The pool class owns the bullets, so ownership is clear, and the game logic only asks the pool for one.
When you write about this in an assignment, state the problem it solves, how you measured the effect and what the trade-off is, such as fixed memory use.
Where Students Get Stuck
- Premature optimization. Measure first.
- Tangled dependencies. Draw a quick diagram of which class uses which.
- Memory bugs that appear later. Check ownership when you write the allocation.
- Large files. Split code into modules before it becomes hard to read.
Study Tips for GAM220
- Revisit GAM110 notes on classes before starting.
- Learn your IDE's debugger and profiler early.
- Commit small, working steps if you use version control.
- Test after each change.
