Bug No more re-spawn after particle death and some strange problems

When I was learning VFXGraph, I immediately ran into frustration, and I don't know if anyone else has found this to be a problem. I don't know how to describe it, I can only post a video and pictures out of it.

this is a so easy example, but you can find some error results.
1.No more re-spawn after particle death.
2.The position of the first vertex of the first strip, which is changed continuously in the following

 

That does look super weird and I do not really get the bug either, but I am curious.
The setup does look very similar to simple heads and trails though?
What's the point of sending Trigger Event on Die 32 times? It is the same value as Capacity, but wouldn't that mean that every particle upon its death sends 32 events? (32 * 32 if they all die in the same frame)?

 

Do you mean that you set it up the way I did and the result is correct? Not the same as me?

About 32, I just wrote it at random when I was testing which parameter was wrong,no definite meaning

 

This is a very, very simple case, I have shown all my modified nodes, output did not add any nodes
1. If I add a lifetime to paritclestrip, only these 2 particles will re-emit when the paritclestrip particles die (because my strip capacity is set to 2). The remaining 30 particles exist forever in memory because of the failure of the previous launch.
2.I have no other node to modify the position of paritclestrip ， only this "set position" in initialize.

 

Is anyone else experiencing the same problem?

 

2 weeks have passed

 

I hate it when I don't get any answers on here xD

okay, I have a huge problem trying to imagine what your expected outcome exactly should look like. But yes absolutely I can reproduce your result. It all looks a bit strange but the core issue mentioned in the title, no more respawn, I think I can answer why that happens.

You start with a particle capacity of 32 and a strip capacity of 2. Hence there will be two strips at any given time, but 32 particles ... so 2 particles with strips, and 30 particles without.

Your particles have a lifetime and die after a certain time. Your particle strips on the other hand do NOT have a lifetime at all and live forever.
No one ever confirmed this to me but to me it seems that as long as there is a strip alive which was spawned by a particle the particle itself can not be fully killed off. A simple script that reads the aliveCount variable from the visual effect can prove this.



This locks your visual effect in a weird state. You can not spawn more particles because you have exhausted your capacity until some are killed off, but the next particle which should be killed off is connected to an immortal strip which completely blocks off killing any particles (or all those are connected to these two strips, who knows).
But due to that you can not get more particles.
Adding a lifetime to the strips and setting the capacity to the same makes this setup more like I would expect it in general but I am still not sure if that is what you were going for.
