Let there be fire =D

Creating a mediocre fire effect on Unity 3D.

Start by clicking create>Particle System under the Hierarchy Pane.

When the particle system selected you can see all its components in the Inspector pane. Under Particle Animator where it asks animate color you want to make sure its checked to make more of a fire effect. Now just below that is 5 options (Color Animation[0-4]) that you can set. When a particle is spawned, it is at first the color of color animation 0. Through out its life time it changes from 0, to 1, 2, 3, and then 4. Further down in the Particle Animator section is the options of force applied on the particles in their x, y, and z axis. Since fire rises I changed the y force variable from 0 to 0.5. (You might also want to mess with the size grow variable to make it a little more realistic) So this is what I have...

The particles right now are still pretty small. So you want to go under the Ellipsoid Particle Emitter component and find the Min and Max size variables. I changed both to 2. To make the fire a tiny more realistic, I messed with the Rnd velocity x, y, and z axis. Pretty much what the random velocity does is add a random force to the particles along the selected axis. So I changes the x and z axis to 0.2 (0.4 is probably better) To make the fire spread out a little more. So what i have is...

So when you hit play you should now see your fire come to life in your scene. This is only one way to create a simple fire effect. In the end it should look like this:

How To Make a Hellish Looking Sky Box

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)

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 scen...

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...
