Well… it’s been a really long time since I did anything physics-related in Blender and maybe some stuff has changed.
One thing I’m trying to do is to get a bunch of small objects like marbles or dice bouncing off of a surface & each other.
I seem to remember setting this up by only having to set rigid body, collision, and initial vector for each object that needed it.
However, when I tried doing this today… no luck. I know I have to set the objects that aren’t moving (like a table surface) to Passive, but I simply cannot remember how to get the rest of the objects “thrown” (what I used to do with a vector), and to have realistic bouncing physics.
This morning I looked up some tutorials, but they seem to start the animation with keyframing - which I’d like to avoid, but don’t know if it’s required now. I can’t find the “initial vector” setting I used to use… maybe it was a plugin…
there are a few other options…but the easiest way would be using keyframes. So on the rigid body, you check “animated” and give it a keyframe so that it moves, then on a keyframe x (after your 2 location keyframes) you keyframe animated, and one keyframe further you keyframe animated unchecked. by this the object takes this “animation speed” as start velocity for the rigid body animation. If this doesn’t work, please provide your blend file try so we can tell you what you did wrong.
Other options would be a bit more complicated: so e.g. you could use constraints, or use other objects to push other rigid body objects, or motors…or…
I don’t use it much for something like this where I use a particle system and key-frames…but have you tried using a force field, or wind? Might work for you I am not sure …
Wait…I just had a thought…
Control it via the RidgidBodyWorld…
Attach your Force/wind/whatever to an empty, and place it in it’s collection…
Call that collection in the RidgidBodyWorld under Settings and Field Weights…
As you can see there is still a problem as it acts on the whole collection as a group pushing it to the left and then the candy does it’s thing and bounces around, most of it now missing the bowl…
