Particles System And Collision

kawak

<div class="IPBDescription">rain fall and "splash"</div> Hello!

I'm trying to do some rains who "splash" when it touch the floor but I've got some problems.

I'm using 1 env_particles called "Rain" and 1 illusion_brush for the "generation entity".
"collide" is checked
"generate system on collision" have the name of the "collision" env_particles (splash).

The rain works perfectly (it falls and stop on contact with a world brush) but the "splash particles" isn't working..

I dont know what settings i have to use for this env_particles..
If i have to use the "velocity params", "generation rate" and "maximum particles"?

Thanks in advance for your help!

i dunno if you can do it that way.... but..

you may could try

[------------------] ceiling
[ps1]
<rainfall>
<rainfall>
<rainfall>
[ps2]
[------------------] floor

the second particle system could just produce the 'rings' or waves effect, using the 'face up' flag. Just start both systems at once.

kawak

yes but i prefer to use the setting "generate system on collision" as it's certainly more realistic (like the lava in Refinery (ns_bast)).

PS to the bast remaker: can you tell me what settings has the second "collision env_custom_particle" in refinery?

Mendasp answered me about the particles effect in Refinery, here is a copy/paste:

<!--QuoteBegin--></div><table border='0' align='center' width='95%' cellpadding='3' cellspacing='1'><tr><td><b>QUOTE</b> </td></tr><tr><td id='QUOTE'><!--QuoteEBegin-->The PS (ore) has "Generate system on collision" triggering "orepuff" which is another env_particles custom with these settings:

But i still dont know what settings i'm missing..

Here is my settings for the "rain":

The collision one still dont work, but worst than that, my fps drop to 20 <!--emo&::marine::--><img src='http://www.natural-selection.org/forums/html//emoticons/marine.gif' border='0' style='vertical-align:middle' alt='marine.gif' /><!--endemo--> Maybe that the collision's settings isn't good with a number of particles over 50? or this is only because something is wrong with the settings..?

Any help is welcome (and i begin to think that i will do the shentrax suggestion.. <!--emo&:p--><img src='http://www.natural-selection.org/forums/html//emoticons/tounge.gif' border='0' style='vertical-align:middle' alt='tounge.gif' /><!--endemo--> )

can you get the splash to work by itself?

1. If you want the particles to be created at the env_particles_custom's origin, then you should have pGenShape set to "Point" and pGenSource left blank. If you want them created within a func_illusionary, then pGenShape should be "Box", "Sphere", or "Blob" and pGenSource should be the targetname of the func_illusionary.
2. You have pVelShape set to "Box", but pVelParams isn't set up for box velocity. It should be:
minx, miny, minz, maxx, maxy, maxz, unused, unused
You have "-225" for one of the unused values - perhaps you meant this:
0, 0, -280, 0, 0, -225, 0, 0

3. Particle systems created by a collision should not have pGenSource set - it is set automatically by the collision code.
4. Particle systems created by a collision should have a non-infinate system lifetime so they eventually stop producing particles. ns_bast used a lifetime of 2 seconds for orepuff, I believe.
5. Point #2 applies to this system's pVelParams, as well. Also, if you use a negative z-velocity, then the particle will be created and immediately fall through the floor. Perhaps you should stick with 0,0,0,0,0,0,0,0 and turn off "Use world gravity".
