I'm sure this is somewhere already on the internet, but I can't seem to find it. Say I want to add some balloons that float upwards in a scene (where gravity is downwards for everything else). What's the best way to go about it? So far, I have set the balloon's mass to almost nothing, and applied an upwards force to it. It seems to work okay, but I'm hoping there is a more appropriate way of doing it.
Thank you
