Log Files
The Console shows errors generated when playing a game within Unity's editor. This
is the preferred method of bug squashing and optimization since the warnings and
errors can be fixed as the game is created. However, there are also log files that are
created when the stand-alone game is run. These log files can be a laborious but
comprehensive form of tracking down what's happening in the game.
Most beginning game designers never have need to access this level of information,
but it's worthwhile to point out that these logs exist and where to find them.
For Mac users, the logs are stored at ∼ /Library/Logs/Unity. For Windows
XP logs are usually stored in C:\Documents and Settings\ UserName \Local
Settings\Application Data\Unity\Editor. On Windows 7 the logs are stored at
C:\Users\ UserName \AppData\Local\Unity\Editor.
It's important to remember though that each time the game is run, the log
(Editor.log) is overwritten. So if you need to compare logs, be sure you're
moving copies of the log out of that folder or renaming them.
Optimizing with Textures
Keeping an eye on the prize of maximum impact with the smallest texture
file size is a nonstop consideration in the creation of textures for a game.
However, often a texture is created at a resolution that we think we need and
turns out not to be needed at that high a resolution. This is commonly where I
find the quickest and most needed optimization to take place.
Remember that when texture files are imported into Unity, by default its max
size is set to 1024. This means that if an image comes in at 512×512, it remains
at 512×512, but if a 2048×2048 image is brought in, Unity down-samples
it to 1024×1024. While putting together the Scene-EntryWay, we looked at
how to up-sample this texture information so that Unity is indeed using the
2048×2048 if it's needed.
What often happens is that when creating a scene and closely scrutinizing
each object, the tendency is to feel the need to up-sample all sorts of
stuff. But when all is said and done, especially when lighting has been
