I'm going to share with you an easy way of creating a 3d Galaxies. Now, there are many ways of making a galaxy, but this example might be easyer than other galaxy methods.

The resolution for this example is a 640*480 window. Pleas adjust the numbers as necessary so the windows size acomodates to this tutorial.

First get a hold of a star gfx, or make one yourself. Animation speed should be around 8 or 10. Around 5 frames should be enough. Set it to ball movement with an initial speed of 0.

You'll need the following events:

I suggest you create "star object" at -100,-100 // I create the stars outside the play area to keep things clean while the positioning is going on

Set X position "star object" to random (640)

Set Y Position "star object" to random (480)

Look in direction of "320,240" // this is half of 640*480, meaning the center of the window

Set direction "star object" to current direction +16

Set speed "star object" to current speed +1

When "star object" leaves playarea: destroy



And there you go. I hope you guys like this article, (hope admins don't delete this one again though, i busted my ass off making an "how to make your game interesting" tutorial but some admin deleted it, too bad he didn't sent me a message telling me why)
Here's a perfect way to create a galaxy, hope you enjoyed it folks.
