Basic Optimization and Unity Tips & Tricks by Yogie Aditya
- 1. Basic Optimization and Unity Tips & Tricks Yogie Aditya, Hinocyber
- 2. Basic Optimization (What) • Well it’s something that you have to do to make your game run well and smoothly
- 3. Basic Optimization (Why) • Game Programming is not just about core mechanic implementation • Editor != Devices • Platform X != PlatformY != Platform Z • You are a Merchant! • Nice!
- 4. Basic Optimization (When) • Depends on the scale of your game • On creation (Based on knowledge and experience) • On polishing (Based on bugs and issues) • Mobile > Web > PC
- 5. Basic Optimization (Who) • Programmer (Code Flow, Math,Asset Management) • Artist (Images Creation, Low/High Poly 3D Models, File size) • Sound Composer (Bitrate, Seamless Music Loops, Extension, Channel/Signals, File size)
- 6. Basic Optimization (How) • Know the limitation of the Game Engine and platforms on which the game would be ported • Game Designer (Angel vs Devil) • Patience
- 7. Basic Optimization (Preliminary) • Draw call :A call to function of the underlying API (e.g Open GLS ES) to draw something on the screen • Fragment :A candidate pixel which may or may not end up on screen for different reason • Batching :To group similar draw calls in one call operating the whole data set • Mobile vs non Mobile Rendering Path : deferred rendering vs Immediate
- 8. Basic Optimization (Tech.) • Don’t use too much collider when you work for mobile games • Object Pooler is King (But better know its weakness) • GameObject.Find(‘’’’) is disaster • Code Caching • Baking • Batching (Static and Dynamic) • Culling (Frustum, Occlusion) • Understand the Rendering Path • Texture Atlas • Always enable ‘Optimized Mesh’ option in Mesh import settings, always enable ‘Optimized Mesh Data’ option in Player Settings (Mostly for 3D Projects) • Optimize your code (Related to Unity functions or not)
- 9. Basic Optimization (Tech.) • CPU Bound • GPU Bound • Bandwidth Bound • Vertices Count • Use Milliseconds (not FPS) • Unity Profiler (Free in Unity 5.x) • Use platform-specific tools • Adreno Profiler (Qualcomm,Adreno) • PerfHUD ES (nVidia,Tegra) • PVRTune, PVRTrace (Imagination tec, PowerVR) • Mali Graphics Debugger (ARM, Mali)
- 10. Basic Optimization (Tech.) • Opaque vsTransparent Image • Texture Compressions • Audio Optimization • Short Clips – Native • Longer (or looping) clips – Compressed in memory • Music – Stream from disc • Files which consistently cause CPU spikes – Decompress on load • Check if everything work properly :D • And many more…
- 11. • Beware of Nesting Prefabs • Gizmos Icon • Drag and drop multiple items with locked Inspector • Understand Unity Execution Orders • Unity Remotes • Unity Documentation Unity Tips & Tricks • Configure your Monodevelop • Use your own Layouts • Do not stress with Play Mode • Debug Mode Inspector • Paste ComponentValues • Paste Multiple ComponentValues • Use Attributes
- 12. That’s all folks! Thank you Any Question?
