Particle systems: Particle Toy

[VilleK]

Hi,

I wrote a test application for particle systems and it turned out quite entertaining so I'm posting it here.

You can set the parameters manually, or just use random settings with the right mouse button. The current particle emitter can be cloned with the left mouse button and then the clones can be pushed around the screen. There is an autopilot-mode which lets it run without user interaction.

Fun, trippy and useless :)

Written in Delphi 6, my favorite Delphi version.

Whoooo pretty colors....... :drunk:









Excellent stuff! Can you tell us something about the inner workings?

Glad you liked it!

I'm writing a game engine in Delphi/Freepascal for small
64kb style games, using procedural techniques.

So the particle system is a kind of "component" in that engine.
I'm developing a small "game IDE" where you can add components
and edit their properties, like in Delphi.

The Particle Toy application, and the other small applications on
my website are developed within the IDE, using the component
editor and scripting language.

Here is an old screenshot of the IDE:

Some very cool stuff there VilleK

Indeed! I'm a particle fan myself. 8) Some nice work.

Any chance of a particle engine primer for the folks here at PGD?

I like the blur (some motion blur i think)..... :fuzzy:

Thanks!

I'm not very good at writing tutorials, but I recommend anyone interested to look at this wiki page (http://en.wikipedia.org/wiki/Particle_system) about particle systems, and the external ]I like the blur (some motion blur i think)[/quote]
It is just a very simple feedback effect. Instead of clearing the screen, draw a fullscreen quad with 0.9 alpha each frame.

I've updated my Particle Toy page with a screensaver version now.
