I think what we’ve all been doing is just using the right click menu in a blank space to search for new nodes to add instead of the library panel. Context sensitive can be confusing when there’s no actual context yet, such as with a blank blueprint.
Also I managed to enforce a speed limit the other day. Basically after you add impulse, get the ball’s current velocity, run that vector through a clamp vector size, then plug that resulting vector into a Set Physics Linear Velocity to enforce the speed limit. Do this as the next event after Add Impulse.
I still need to figure out how to slow to a stop, been busy the last few days so I haven’t been able to work on this. I’ll post my results once I get somewhere.
