How to Instantiate!

When you instantiate something, you clone it, put it in the position you want, and the rotation you want. A very simple command. Done like this:

function Update(){
    Instantiate(transform, transform.position, transform.rotation);
}

So basically what this script does is clones what ever the script is attached to at the position of the object, and its rotation. Not really the best thing. Better yet it's in the Update function, which is being called every frame thats rendered, so thats allot of clones ha..

Using this to our advantage, we can use Instantiate to help us create an explosion effect =D

var explosion : Transform;

function OnCollisionEnter(){
    Instantiate(explosion, transform.position, transform.rotation);
    Destroy (gameObject);
}

Function on collision enter is called when one object has collided with another object, noting that they both have to have a mesh collider/rigid body attached to them. The instantiate statement clones the object that we assigned in the variable, which would be an explosion prefab. The Destroy (gameObject) deletes what ever the script is attached to.

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.
