[Plib-users] ssgaParticleSystem problem

[McEvoy, N. <nic...@ds...>]

I'm using ssgaParticleSystem to simulate water shooting out of the back of a jet-ski.

I find that as I change the rate (setCreationRate) of the generated particles (depending on the jet-ski power) ... there are particles that do not seem to being updated ...

If the creation rate is constant ... everything is fine.

As I reduce the creation rate (say from 100 to 90) ... there are 10 particles 'frozen' in the air ... they will disappear after time-to-live ...

If creation rate changes from 90 back to 100 ... say before the particles disappear ... they will start to be updated once again !

I had a look at the ssgaParticleSystem code, but I'm not sure why this is occurring.

Any ideas ?

Hi Nick!

I had the same problem and looking through the sources I found that
in ssgaParticleSystem.cxx there's a commented line:

// rawSetNumVertices ( j ) ; /* Avoid drawing more than 'j' vertices. */

I decommented it and rebuilt the lib. All is working fine now.
I don't know why it is commented by default, hope it doesn't give some
weird problem :)

Hope this could help!
