I have something that is slight similar but i cant figure out how to get the coins to start falling down. I have posted a screen shot of my settings and a link to a clip of the coins (the screen capture came out very choppy, but it gets the general idea across)
Turn it higher to see the effect. However, if you want them to already start falling down, turn the particle (and make sure if you already have a prefab you apply the changes) 180 degrees. (If turning it upside down doesn’t exactly work, change one of the settings from World to Local)
Ok so after playing around with different methods, I found that using a cone emitter and rotating it -90 degrees gave me the type of fall that i wanted.
currently, you can see the coins are mainly rotating in one axis. In unity, I have “Rotation over lifetime” set to “random between two tan gets” and the values are 180-360. Does anyone know of a way to have to coins rotate on more than one axis at a time?
