3D looking Yellow-Bellied Sea Snake that follows the mouse cursor. All vector.
You can also make your own custom creature, it’s just a matter of modifying the sea_snake Movie Clip. Once you open it, it’s easy to see how it’s done.
To get an idea of what you can do with imagination and patience, check out my 3D Boar Fish file below. It uses the very same code as this snake with only some simple adjustments to wiggle speed/strength and mouse follow speed, which is easy to do.
To put it in your own project, just copy the sea_snake Movie Clip into your Library, and put the code Movie Clip somewhere on the Stage. Easy!
You can of course use any background you like, just put the code Movie Clip on the layer you want the snake to appear on.
The actionscript is simple and well commented and a small help file is included.
If you need any help, just ask!
