Debug Rays =D

I use them for looking at what enemies are looking or aiming at. Since it's Debug it only shows up in the scene view and not in your actual game play. They  can be very useful sometimes. Here's an example of what they look like. The red lines are the debug rays.

How I'm doing it:

Debug.DrawRay (transform.position, Vector3.forward*100  , Color.red);

So debug is a class that contains that governs all the debugging functions.

DrawRay is the function we want to draw the line.

Then the next part of the code goes like:
(Position of where the ray will start which is a Vector3, direction of ray and how long, and then the color of it)

For the direction of a ray it can go 6 ways. (up, down, left, right, forward, backward)
Vector3.forward is just shortcut instead of saying Vector3(0,0,1)
And for those who aren't familiar with Vector3, its just 3 coordinates to define a object in 3d space. It goes (x position, y position, z position). x is left and right. y is up and down, and z is forward and backward.

Colors you can either make by using the class variables or by using one of it's predefined colors. In the colors class, it's predefined variables are : red, green, blue, white, black, yellow, cyan, magenta, grey, and clear. Read more on the colors class here.

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…

Fixing Sketch Up blank window (white box) problem

When downgrading my OS over Christmas, I was faced with many problems, one of which is getting my Google sketch-up working.

Almost everything was working perfectly, except one little thing, The 3D Warehouse.



It was just displaying a blank screen. At first I thought I had blocked permissions for giving it internet access.  Though my computer said it was allowing it to go over the network. I tried turning off my firewall and still nothing happened. I don't have any anti-virus software so I didn't worry about that.

Guess what fixed it this annoying problem?

Updating INTERNET EXPLORER.
Just check for updates, and updates for what ever you computers default browser is also.

Now everything's back in harmony


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 …
