Question Starting movement one particle after another

Hi,
I started working with the vfx graph in Unity and things are going pretty well so far, except for one operation I can't achieve: I have a square grid of particles spawned with a single burst. Then the particles should just move up until their lifetime is over, no problem with that. What I need to achieve is the particles starting to move one after another, e.g. with a delay between each particle starting to move. I've searched docs and tutorials with no luck, which makes me ashamed because I have the feeling this should be fairly simple. Can someone help the noob? ^^'

 

If they must be spawned at the same time, but start with delay then the easiest way I can think of is to assign some "startTime" to each particle, it can be simply

delay * spawnIndex + currentTime

, then you check every frame if that number is smaller than current frame time to see if enogh time passed. If this evaluates to true you eable some block you want, in your case "add position" (multiplied by delta time to make it move smooth).

 

Thank you very much!

 

Thank you Marie!
