sript test

#6

Thanks, I wright the same script but I didnt use parameter pCont.useTime = true

now its working

It should work regardless if that channel is initiated or not, AFAIK. You are only seeing the channel and not altering it.

is it the fact that the Init needs a seed value? or something else?

Forgive my niaveness, I saw the pcont.randXX functions but was unable to figure out how to set a lower limit. None of the functions seem to be able to set a range other than 0 - …

IE theValue = pcont.rand01() ? i was hoping it would be simple like [50, 100] or 50 100 but it just generates some random #

and

theValue = pcont.rand0X 100 --you can set the upper but how can you set the lower limit?

#7

The proper expression is:

val = desiredHeight + desiredRandomnessMagnitude*pCont.rand55

Thanks,
Oleg B.

#8

Ah I see, thanks :slight_smile: and mental note to self “remember to use expressions” not just functions :smiley:

theValue = 100 + 100*pcont.rand55() :wink:

#9

Is there some reason you need to do this with a script test? Wouldn’t it be easier to just use a volume select and set the position object to selected faces / verts ?

#10

A volume select is not the fastest thing in the world, mildly put :smiley:

#11

Another way would be a deflector + collision-test.

#12

Neither is a script test. :wink: It depends on the geometry really. If you have a lowish poly geometry emitter I think the volume select would be faster and easier to control in this case. Feel free to speed test and prove me wrong though :slight_smile:

#13

Well this sparked my curiosity…simple scene, 200 frames, 10000 particles born and locked on a noise animated plane, whenever a z-axis of 10 is reached the particles pass to new event, some speed is introduced,spawn once, 5 five later age test to delete.

Script Test - 29.11

Group Selection and Split Group test - 13.609

Box#3 Z-pos Data Test - 13.25 (lol, almost always fastest, something I already had a good idea would be)

Box#3 Data Icon Distance test - 15.187

Collision Test w/ std Deflector - 29.235

I should mention all of the times are actually a bit faster, the script I wrote to test with has to actually move the timeslider, so there is some disparity there.

#14

Cool test dude :slight_smile: Box #3 always comes on top, I don’t know why people bother scripting any more heheh. You might send me the scene so I can evlaluate how fast TP is in that operation.

#15

With this animation collision test and volume select is not usable ))

With this script for script test particles from event01 go to event02, but I need that particles on event01 always stay and generate new particles on event02.
I found parameter pCont.AddParticle() that add particles.

on ChannelsUsed pCont do
(
pCont.usePosition = true
pCont.useTime = true

)

on Init pCont do
(

)

on Proceed pCont do
(
count = pCont.NumParticles()
for i in 1 to count do
(
pCont.particleIndex = i
if pCont.particlePosition.z > 20 then – all particles inside a sphere with radius 20 satisfy the test
(
pCont.AddParticle()
pCont.particleIndex = pCont.NumParticles() – last particle that was added
pCont.particleTestStatus = true
pCont.particleTestTime = pCont.particleTime
)
)
)

on Release pCont do
(

)

with this script particles generate on the PF icon. Is it possible generate that particles from position of particles on event01?

I want after script test particles generate all time on wave crest. Maybe I go to wrong way?

#16

Change the content of your if statement to this:

pos = pCont.ParticlePosition
pCont.AddParticle()
pCont.particleIndex = pCont.NumParticles()
pCont.ParticlePosition = pos
pCont.particleTestStatus = true
pCont.particleTestTime = pCont.particleTime
#17

thanks, now it working good )

but I have new problem, when wave crest go down particle generation end when it going via Z pos that stated in if statement.

#18

You can add a new Event. Send the particles to event 2 (with the z.position part of the script) and in this event you add another script test, where you spawn the particles (with the other part of the script).

With a third script test you can send the particles that reach z = 0 to a third event, where they stop spawning new particles.

#19

Can U show me? I dont understand how can I do this, because first script test on event01 send particles to event02 and It loose surface position

#20

Sorry, you’re right. that doesn’t work right.

But I found a solution that worked for me. I added an array to the script, where I store a boolean value for every particle. When a particle reaches z = 20, the corresponding value is set to true. At z = 0 it is set o false again. In an additional if statement, that value determines if a particle is spawned.

Here’s the Code:

on ChannelsUsed pCont do

(
 pCont.useTime = true	
 pCont.usePosition = true
)

on Init pCont do 
(
global SpawnArr = #()
)

on Proceed pCont do 
(
	
	count = pCont.NumParticles()
	for i in 1 to count do
	(
		pCont.particleIndex = i
		if pCont.particlePosition.z > 20 then 
		(
			SpawnArr[i] = true
		)

		if SpawnArr[i] == true then
		(
			pos = pCont.particlePosition
			pCont.AddParticle()
			pCont.ParticleIndex = pCont.NumParticles()
			pCont.particlePosition = pos
			pCont.particleTestStatus = true
			pCont.particleTestTime = pCont.particleTime
		)

		pCont.particleIndex = i
		if pCont.particlePosition.z = 0 then 
		(
			SpawnArr[i] = false
		)
	)
)
on Release pCont do 
()
#21

not working for me, particles stay in event01…

#22

Sorry. Maybe I wasn’t clear enough.

Forget the whole idea with sending the particles to event2. This is a script that spawns particles when the base particles reach z = 20 and continue spawning untill they reach z = 0.

#23

I paste this script to script test and it not working…
Maybe I have to change something in a PF structure?

#24

Strange. I just tested it and it really didn’t work. Then I rewrote the script and it did work…

I attached a sample scene and the script. I hope you can open it (Max 2008) and I hope it will work…

Edit: I think I know where messed up. I swaped two lines. Corrected the above code.

#25

yep, script from your scene is working ) thanks
