My 2d particle library! Updated

That looks really nice. The right click explosions are my favourite

Works great on my laptop!

Debugger off:

61 FPS with an average 52,000 particles

Debugger on:

11 FPS with an average 49,000 particles

Note: Debugger on and right-clicks slowed my machine down to 2 FPS! Ack!

Thanks for sharing!

Looking nice, with debugger enabled or disabled, it doesnt matter, 6,000 particles slow it down to 4FPS. Still, not bad at all

Got any more up your sleeves?

6000 particles at 4 FPS, that's bad

I think the "engine" is fast enough as long as you don't right click...
And I really want to know how I can make it even faster

And everybody, thanks for the nice comments!

I'll see if I can make it into a nice screensaver with random fireworks someday.

Well, for left click, the highest it has gotten is 56,000, and stayed around that, but thats at 46FPS. So not shabby

@Joakim Christiansen: This is absolutely awesome & beautiful !! Works well on my Dell Optiplex. Thanks for sharing your code. I think my young kids will enjoy seeing this!

Should be able to make it faster by plotting directly in the screen buffer, but i'm not shure how to do that. (could anyone do that?)

And if there is many particles on the screen and I make new particles with mb-right it gets mysteriously slow..., but the mb-left particles don't slow down that way. I think it got something to do with linked list mess...

(but I think there might be a smart way to make it faster...?)

Very nice.

I just found a way to make it even faster, you can now hold down the right mousebutton without getting a slowdown!

I updated the first post with new code, go and get it!

dont work here with v4 final... macro error on this line :roll:

Code: Select all

If  PL_Particle()\Step >  PL_Particle()\Duration Or  PL_Particle()\X <0> #ScreenWidth-1 Or  PL_Particle()\Y <0> #ScreenHeight-1

I'm also using PB4 final, I don't understand this

It gives you an error on that line if #ScreenHeight and #ScreenWidth is not declared.
Did you save both files and executed the example?

And yeah, I know it's stupid, but I don't know any other way of getting the screen width and height...

EDIT: Oh... I now see what you're talking about!
The forum messed up the code... bether download it then!

Wow, works fantastic on my old 1 GHz Dell laptop.... drops to roughly 40 fps with 20000 particles (holding right mouse) and around 25 fps with 50000 particles (holding left mouse). Impressive.

Joakim, the latest update works well for me (Dell P4) - getting around 70 FPS. Thanks for making it available.

I'm now going to make a fireworks screensaver with random explosions, it's allready looking neat!

Joakim, bring it on! please let us have a look!:)
