Dependent on the time-lapse lib, the animation code provides you with several count methods to manipulate your animations in an easy and comprehensible way.

If you add a sprite atlas library (I’ll share later) you’ll be able to manipulate sprites with animation in quite a flexible way without too much hassle.

The idea is to encapsulate the animation functionality in such a way that it makes it easy to work with. You have the ability to start, stop, pause, change speed, etc. You can create animations that range from any frame to any frame and that can animate in many ways such as sequential (loop), play-once and ping-pong (back and forth, or rather the inverse). By making use of the time-lapse library we can easily create time-based animation.

This little lib is used to keep track of time using the low resolution timer provided by the OS (in Windows “GetTickCount”). The goal of this type of library is to encapsulate timing actions. It was originally designed for game development in mind but needless to say you can use it and adapt it to your own needs.

Basically you define a time interval as you create the “timelapse” instance. Every time you call the update function a simple check determines whether the time was reached or not. This is trivial, but encapsulating it makes sense. Specially if you plan to create an animation system in the future!

I recently required some vector functions to prototype a game idea in PureBasic, however there is no such thing as a built-in vector library and any of the existent community code was buggy to say the least (no offense but it’s old, ugly code that you’ll find anywhere else).

The reason for this library is quite simple, and so is the library itself. you can either include it or install the resource file and start using it right away. After taking a quick look at the source, you’ll soon familiarize with it’s naming convention; there is no need to write any documentation for this type of code, since it’s basic vector math. However a test source is included for your delight.

You can find the source in here: http://gushh.net/dev/?file=pb/vec3_macro.pbi
And some ugly test code in here: http://gushh.net/dev/?file=pb/vec3_macro_test.pb

Or, you can get “the whole package” from here: http://gushh.net/dls/vec3_macro.zip

Using this library is as easy as…

Define.VEC3 a, b, c
VEC3_SET( a, 0.1, 0.2, 0.3 )
VEC3_SET( b, 0.4, 0.5, 0.6 )
VEC3_ADD( a, b, c )
VEC3_DEBUG3( a, b, c ) ; display the vectors in the debug console.
