Moving a ParticleSystem - why does Unity interpolate its position?

Here is my case:


The particles should be played at the meteor position when it was clicked, but it is played in a very "old" position (you can see some frags on the top left corner when the meteor disappears), this only happens when the game is running below 60fps, at around <40fps I guess.

 

This is still a bug with Unity 5.3.1p4.....

Notice the delay in the subparticle emitter. It looks like subemitters are delayed by up to many frames and not called on the same frame as the parent emitter. My question is how the heck this has been a problem since 2012 and still not properly resolved.

 

Now that the OP is from the UT staff he could speed up things for us about this bug right? lol

 

If you learned anything then you know they bought him out to stop talking about the bug

 

The sad part is that it was considered "fixed" 4 years ago but it looks like it was not yet fixed:

so, maybe you're not wrong haha

 

shall we open up another bug report then ?

 

Hi, I have just submited the bug, here is the ID: 765777
and this is the ticket number: 765777_i0h34elif7r4q7fd
Didn't know which was the one you wanted. I used the reproduction case that was kindly provided here by tedd.hansen:
http://forum.unity3d.com/threads/mo...interpolate-its-position.134283/#post-2262505

Good luck!
EDIT: in the bug report I forgot to say that in the repro case you just have to load the Test scene and hit play!

 

Hey guys, after talking with the support guy about this bug, it seems that its fixed (tested it on 5.3.2p1). The case provided by tedd.hansen seems to work correctly now, and my old project also works without that "hack".
See if you can try it out too and check if it's also fixed for you.

 

Hi,

Just letting you know that it seems the bug is back with the new 5.5 release. It may also be because of how the new particle system works.

 

Using Unity 2017.4.1f1, bug is still present.

Papatsu's solution still works! Yay!

 

Your solution really help me，Thank you share this.
2017.4.3 still has this problem.

 

The problem with the workaround is with the laser effect when it "hits" something. I want to stop interpolation if it suddenly hits an object far away instead of some "close" object, but if I keep calling Simulate(0f) it will freeze it.

 

The bug was broken again, due to the inverse bug being fixed. Please can this be updated.

Did you find a good solution? The workarounds I did in this thread don't work (and I need it in world space).

 

I have filed it now: https://fogbugz.unity3d.com/default.asp?1378785_bvanmlfq6msap2j3

Thank you.

 

Is this fixed? I'm seeing something similar in my PS.
