Is there a way to have trueParticles produce something on a certain frame, rather than at a regular interval. I mean, I would want a sphere to be made at frame 2, then again at 10, then perhaps at 22... as it stands, I can only produce the sphere at 0.1 rate... which is still far too often than anything I can work with (and that's the lowest???). I find it a bit strange that I am unable to do exactly what I want with it. I have another plugin called 'gunfire' I think, which allows you to time it correctly, but does not enable physics, which is what I need.
Can anyone suggest anything? :confused: |

One more question... is there a way to make the particles collide with each other? As it stands they all merge into one sphere at the end...
Thanks |

I have only toyed with Primal Particles - this does repsond to physics (of a sort - you can introduce gravity or wind type factors easily) but as far as I can see doesn't offer specific frame control on timing, just a variable rate from 'dribble' up to 'explode'.
Might be worth checking if the lowest speed is any slower than trueparticles? |

The particles are not self colliding. |

Darn... I need the physics to allow the objects to collide with something. To be honest I don't need them to be able to collide with each other, but it's just a shame. It might be possible to recreate some water using metaparticles like that. Ah well... that's the second animation I've been unable to make with trueSpace... darn it, I'll have to get back to the drawing board and come up with a new (3rd) idea. |

You should be able to make the particles collide with an object even if not with each other - see Burnart's thread on 'wayward particles spray', referring to the use of bounce objects (albeit with some problems!)

Quite correct - trueParticles allows you to natively have the particles collide with one object but by using the tS physics the particles can collide with multiple objects.
As for the original question as to whether particles can collide with each other - the answer to that is no.
0.1 might be the lowest rate that trueParticles allows you to create particles using the spinner buttons, but try typing 0.01 into the dialogue. |

Yes, sadly I was referring to the suggestion of using Primal Particles for use with physics. I was hoping to create an animation having the balls hit drums in time with music. At first I was pleased because the particles seem to bounce of the drums perfectly, but unfortunately it will only be useful to me if I have a constant beat in the background... and that simply won't look very good. I'm yet to find a decent use for trueParticles, where Primal Particles FX ROCKS!!!

Nope, if I type in a lower value it says "Please enter between 0.1 and ..." so it looks like the drawing boards really are my only destination. Big shame... scuha vision wasted, lol.
Thanks for your help though guys. |

From your description it would never occur to me to use particles in the first place. My initial reaction would be to use objects with physical properties and an initial motion vector, then run a physical sim to create the animation. For something as repetitious as a ball hitting a drum I'd probably just do it the once then hand copy the motion path to create the repeats with the correct timing. |

Have you checked out the Music Machine tutorial Caligari has?
http://www.caligari.com/products/trueSpace/ts5/Courses/Newmusicmachine.asp?Cate=Training&SubCate=Master
It goes through the process of animating balls bouncing off of strings all synced to music. That might give you some ideas...

EDIT: What Bobbins wrote is the exact process the tutorial uses... |

The drum beats would be loads... so that's just far too much effort for something that's just a bit of fun. Plus I wanted the particles to be fired from an object, so I could figure out all the angle and stuff. Never Mind. |

To create a single particle at a given frame, simply set the Emit Start and Emit Stop (in the Motion tab) to that frame. Hope this helps. If by some chance you are still on this project, or interested. |
