    Hello,

    I am making a game in 2D, and am relatively new to using particle systems, but I can't seem to be able to achieve a scatter effect. I illustrated a basic example of what I am trying to go for, but I am instead getting particles that are scattered nonuniform, which are also not emitting from the center of my shape, which is a circle. I attached an image of that too. If anyone can show me the correct settings I would need to do this, that would be heavily appreciated.

    Thanks!

    You need to use one of the non-randomised shape module modes. Eg loop or burst spread.

    If using burst spread, turn off rate emission in the emission module and add a burst instead.

    Isn't that the way I currently have it though? I have it at burst spread, and in the emission tab I have enabled the burst effect and set the corresponding variables in those fields, and set the other fields like rate of emission to 0

    Ah sorry yes you do!

    Set radius thickness to 0.
    Right now particles are being spawned randomly along the radius of the circle. You want them always from the edge, for a uniform spread.

    Ah okay, I did that, and decreased the radius size significantly too, and now everything lines up! Thank you so much!
