How to Get There?• Most common problem is game architecture is wrong • Further complicated by poor organization• Building in Unity is fast, can become messy fast too• So is there a better way?

Starting Off Right• Building anything of substance requires some planning • But doesn’t necessarily take a lot of time• Identify requirements and key features of your game• Prototype and test specific things on target platform(s)• Document findings• Team agreement on constraints• Capture core design using data-centric approach

Platform Prototype• Not a gameplay prototype!• Complexity test on target hardware • Graphics capability and performance • Memory usage and performance• Use simple, but representative, assets • Correct polygon count, pixel size, shaders, etc.• Use profiler to assess feasibility• Repeat until you have a clear idea of how the game will be put together

Example: iOS 2D Action Game• Large static background• Player is “Defender”• “Raiders” attempt to raid “Treasure”• Both Defender(s) and Raiders use “Weapons”• Will a large background image cause problems on iOS?• Will a large number of separate alpha-sorted Raider and Weapon sprites cause framerate hiccups?• Do we need to pack sprites into atlases?

Data Prototype• Approach development as a data problem• Identify the data, structure and relationships • Consider how designers will modify properties • Designer scenes, exposed properties, XML, etc.• Create test sets of data with team, design outward from there• Consider how art, design and code will come together to implement the requirements and features• Data helps define scope of what you’re building

Workflow Tips• Get organized, stay organized• Use sensible folder structures• Use meaningful names• Unity is GUID, not path, based • Can move things around freely• Don’t nest Resources folder, keep at root• Stage incoming assets outside assets folder• Use design-time only scenes, don’t mix

Technical Tips• Learn, understand and use Unity’s awesome component architecture• Create project and global script templates• Use lazy initialization• Use static public methods instead of instance methods• Enable objects from pools rather than Instantiate/Destroy• Consider separate cameras for scene and GUI• Write custom editor scripts• Refactor often
