Making your materials A little more realistic.. (Normal Maps and Bumped Diffuse)

How to go from this:

To this:

So start with finding a nice seamless(optional) image for a texture you want to put on an object. A great place to find plenty of detailed seamless textures is Filter Forge. You can search their filter library and find plenty of great textures that are seamless. The texture I'm using can be found here. Once you have found and saved the image you want, you need to import it to Unity 3D. Once you have imported it, it should show up in your projects pane. Duplicate the image by clicking on it in projects and hitting Ctrl + D. Once you have the duplicate, create a new material by going to Project>Create>Material.

Once you have your material created, select the Shader from diffused, to Bumped Diffuse

In the main texture, select the texture(image) you imported.
Now in the duplicated texture, change the texture type from texture to normal map.
Then click apply, you should get something like this:

So go back to your material, and for your second option, put in the duplicate image you just modified. So now you should have this:

So you can apply your material to any of your game objects, and when light hits it, it becomes more defined and 3D like. Comment for any questions, if I need to be any more clear, typos, mess ups, sudjestions, please comment. XD but I doubt anyones actually even going to read this

How To Import and Use Fonts

-Made by Chrome Fx Films

To use different fonts in your game, your going to have to acquire some fonts. You can go somewhere like 1001 free fonts and download ones you like and want to use.

When you download the file, you'll need to extract the file if its in  a .zip

The text file should have the extension .ttf. If you text files have a FFIL extension, simply rename the font file (yourname.ttf).
Drag the text file into unity to import. By default the Character variable should be labeled Dynamic.

The Dynamic setting means  that Unity won't pre-generate the texture, so if you look at your material containing your font, It probably will be blank. (read more here)
Now your over all objective should be getting your font to look like this (unless you prefer dynamic):
Where the characters of the font are not jumbled up and visible.
Now usually all you have to do to achieve this is change the Character variable from Dynamic to Unicode.
and that should work.
Now what some people over…

Handling Music and Sound Effects In Your Games

Initiative  While developing Treva's Adventure I had to figure out a way to handle multiple music tracks and sound effects in a clean manner or suffer horribly.  What was going to help me achieve a simple solution was taking all the different sounds and centralizing them in a single class in order to black box them.  Any other code trying to play a sound wouldn't even know the sound file's name.  All code trying to play a music track would reference a enum that defines all the track names.
Defining The Class Creating The Enum When I first started defining types in my enumeration,  I was naming the types to be exactly like the file name.  For a scary sound effect I had found a file named "ghost breath".  So around my code would be scattered lines like SoundManager.Play(SoundEffectType.GhostBreath);  This was fine until I found a sound that better fit the situation it was being used in,  and decided to use "ghost breath" for a different situation like a …

Don't Destroy On Load..

So if you want to keep an object or script that keeps up variables (or for any other reason) when you go from scene to scene, you need to attach a don't destroy on load static function, which goes something like this:

function Awake () {
    DontDestroyOnLoad (transform.gameObject);

The Awake function is call only once, when all the objects in the scene have been created. Read more about it here.

DontDestroyOnLoad has what ever is in the ( ) to not be destroyed when creating a new scene.

(transform.gameObject) is what will not be destroyed when the new scene is loaded, in this case, it will be the game object and all it's children the script is attached to.
