Very often I need my particle effects to look more predictable, e.g explosion particles to get spread in all directions without getting bunched up, because it often looks ugly. Do I need to provide visual examples? I think the idea and the need for this should be pretty clear.
There should be a parameter between 1-0 that would control how evenly distributed particle directions are. Possibly, the same parameter is needed for position distribution.
As an implementation, I imagine that emitter could be subdivided into sectors internally and instead of getting a random value from the entire range, it would pick a random sector, and then pick a point/direction in it, and mark the sector as used. It would iterate through all of them before reusing one.
For now, I’ll have to write a script that does that for me. I bet a lot of people need this often for effects that look more appealing. It is very ugly when you need a few very visible particles to burst in all directions and instead they come out from one side, or when there are big gaps in the effects that supposed to look more ordered.
It’s mostly needed for direction distribution in burst effects.
