here's my particle library It's more or less untested because I haven't implemented it into my engine just yet, i think ill do that in a few days..

Its very handy, you specify a particle emitter by ID number, 0 thru virtually unlimited, each particle in the emitter is given certain properties based on how you called the configure functions..

and then a single "UPDATE_PARTICLES" function needs to be called and that's it every single particle's property is available at any time anywhere in the program, so you could get some nifty things going on... you can change them on a global scale or just a single particle to your likeing I hope you like it!

Nice water effect!

Could you rem it though?

DANGIT NEO, YOU CHANGED THE CODE AND NOW THE MATRIX WONT TEXTURE RIGHT.

what water effect, that's the particle library

You choose what kind of particle you want.. how big it is, and its x y and z velocities, this means it can work for smoke, rain, snow (with some work), and just about anything else, trails..whatever

I updated it with some few fixes, no new features yet, but soon for some more basic functionality..

Also in the new version i made a fountain so you can see the particles surrounding some basic scentery.

The only part of the code you need to include is the plib.dba and then just call the functions similar to how they are called in the demo Good luck

well i took a few more hours into it, and updated it a lot more, lots of bug fixes, and two new features

POSITION_EMITTER(id,x,y,z)
POINT_EMITTER(id,x,y,z)

edit: wow i didn't think my proggy was so buggy, changed some function names, fixed a lot more bugs, and added some functions to break it up a little... should be a little faster and a little more useful

No sin or cosin calls. Might be faster than mine then. We'll see, Oh we will see!

well, it does require quite a bit of variables and variable calls. Then again its a very verstatile lib, so I would say that if your game only requires one or two particle emitters that don't really change or anything, to just make a simple particle generator on your own...

However if you need to change the velocities of the particles, appearence, stop and start them and move em around, then this library is very effective

well, I think ive got all the functionality i need done in this library...

The documentation hasn't been updated yet, so just follow the example code and you should figure it out...

any bugs please report them

I should have the docs updated in a few days or so...
If there's any features you think are missing please advise!!
