So I’m experimenting with particle emitters, but I have a question for Rotation and RotSpeed. Should I use {0, 360} for let’s say RotSpeed or {-180, 180}? I see some people do this and the second one seems more smooth. Are they the same thing? Can someone tell me the difference and which one to use?
Both the first and the second values have the same range. But, their absolute values are different, thus, their speeds are going to be different.
The first value {0, 360} can be x2 faster than the second and only spins in one direction (since it’s positive numbers).
The second value {-180, 180} creates a range from speed 180 in one direction and speed 180 in the other direction. It’s never going to be faster than 180. Therefore, the possibilities are quite less in terms of speed (not direction). This looks better, as you mentioned, because it won’t look too random. It would look awkward if one particle is slow, and then comes a super-fast spinning one, which is the case with the first value. Also, as I said before, the particles using the second value can spin in both directions, while the first value would allow only one.
Here’s a little video. [color=blue]Blue[/color] is the {0, 360} and [color=red]red[/color] is {-180, 180}.
