Just something I cooked up when I was creating my first game in Unity (Hover World). I cleaned it up a bit and am releasing it for anyone interested (feel free to delete it, rewrite it, change it and use it for any purpose).
It’s a script that generates lightning bolts or sparks from one object to another. I’m not sure how useful it is, but I had fun creating it. There are some limitations noted in the script header.
After you import the package you will find a unity file called test.unity. Its a simple sphere and plane and if you press ‘play’ you should see some bolts/sparks between the two objects. More info can be found in the script.
Cheers,

Nice effort. 
Although the effect you’ve created is fairly basic, the script is well documented and covers a good range concepts.
I had a quick play with it and discovered that the fade out effect (value) only seems to work when the plane isn’t beneath the sphere.
Thanks! Yes, the fade out effect is a bit of a misnomer. It’s simply the distance where the sparks end if there is no object below the sphere…

I just tried doing a NEW inside unity, and the iMPORT PACKAGE with your package, and I got a beep and nothing happened. How do I try out your example, sorry I am very new to Unity. :?:
That’s pretty much the way to do it… maybe you are running Unity 1.6 instead of 2.0?
Cheers,

I have the 2.0 demo, just trying it out today, when i click import I still show my island assets all other screens are empty.
In Unity 2.0:
Step 1 - make a new project
Step 2 - double-click the package file while that new project is still open
Step 3 - open the scene called “test”
Step 4 - press play (or cmd-P) and watch the lightning
If you have a project open and double-click or import a package file then the package contents are dumped into that project folder and may be lost/jumbled in with everything else. In the case of the island demo you’ve just added the package file contents into a rather large and involved project making those new assets harder to find. Not lost, just harder to find (look for a scene called “test” in your case now).
