make the balls fall a bit faster once they've entered the bins #63

Closed pixelzoom closed 8 years ago

pixelzoom commented 8 years ago

On the Intro screen, make the balls fall a bit faster once they've entered the bins (cylinders).

Skype discussion:

[8/29/16, 8:26:45 PM] Ariel Paul: is there any comment about the balls on the first screen falling into the cylinders [8/29/16, 8:26:57 PM] Ariel Paul: when they reach the cylinders they appear to slow down [8/29/16, 8:27:02 PM] Ariel Paul: and then fall at a constant rate [8/29/16, 8:27:20 PM] Chris Malley: checking... [8/29/16, 8:27:28 PM] Ariel Paul: to my eye, they should probably fall a little faster, but I was curious if there is any comment about the rate they are falling [8/29/16, 8:28:38 PM] Chris Malley: I see no acceleration or velocity change mentioned in the code. [8/29/16, 8:29:14 PM] Ariel Paul: Do you have any thoughts when you watch it....it just looks a little odd to me [8/29/16, 8:30:12 PM] Chris Malley: Hadn't really bothered me to be honest. Do you want it to just move a little faster when it's in the cylinder? [8/29/16, 8:30:52 PM] Ariel Paul: I think so [8/29/16, 8:31:23 PM] Ariel Paul: I don't think it has to accelerate, but if feels a bit "molassas-ee" [8/29/16, 8:31:50 PM] Chris Malley: alrighty, I'll capture this discussion in an issue.

Just to add, I don't think it needs to speed up much (probably make a tweakable parameter just so we can dial it in) but I am guessing 25 to 50 percent faster

Increased speed in the bin by 2x, reviewed with @ariel-phet via Skype, closing.

I am seeing this change in dev.9 and it looks fine to me.

Thanks @amanda-phet. Sorry you weren't in the loop on this one.
