Debug Rays =D

By
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 Make a Hellish Looking Sky Box

By
I came across this problem while constructing my scene of Hell in a little project I've been working on, and could not find a reasonable sky box on the web for what I want. Maybe I was not looking hard enough, but I ended up making nice substitute. If you think the sky box looks familiar, then your right. The Sky box I'm using is already packaged with Unity3D! To import the sky boxes Unity has made for you,  simply go to Assets>Import Package>Skyboxes.  The sky boxes will appear in your projects tab under a folder named "Standard Assets". To make this sky box, first you must find the folder containing all the sky box materials and open it up. In it will be a list of sky boxes for your disposal. To get this skybox, I decided to tweak the "StarryNight Skybox" (But the "MoonShine Skybox" looks pretty cool also!).  Select the sky box and view it under the inspector tab. Underneath the properties there will be a tint color variable allowin

How To Make A Gun Shot Sound (SFX On Unity 3D)

By
When it comes to audio in Unity, there are four components: Audio Clip , Audio Source , Audio Listener , and Audio Re-verb Zone . Audio Clips are the actual audio file imported into your game. Unity supports file formats: .aif, .wav, .mp3, and .ogg. When imported, you can compress them greatly, with the price of loosing some quality. You can do this by first selecting the audio clip, view it in the inspector. Under the Audio Importer component, you can switch the audio format from Native to the audio clip, to a compressed format applied by Unity. You can change how compressed the file is by dragging the bar at the bottom, then hitting apply. You can get plenty of free good SFX from a site called  freesound.org . All you have to do is create an account for free , and download all the sounds you want. I found a nice gun shot sound here . Simply download and load into your Project. Audio Source actually plays the audio clip in your scene. They are an component, so it mu

Handling Music and Sound Effects In Your Games

By
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 s
