Need Advice: Creating video for one of my audio productions just for fun.

Analog-X64

Hello Everyone,

I'm trying to make a music video for one of my audio productions, in the style of Demo Scene of the old 8-bit / 16-bit era.
For those who might not know, Demo's where written by bedroom coders as a way of showing off their programming skills as well showing off the graphics/audio abilities of the computers for the 80's/90's era.
Here is a good video with a good set of examples: https://www.youtube.com/watch?v=pssH6moTGLc

Since I cant pull this off programming, I figure I'll use Carrara to recreate some of the scenes or close proximity of them, just for one.

I'm trying to re-create the famous Amiga Boing Ball demo and failing.

Scene Setup:
Cube with UVMaped texture top and front are set to transparent so the inside contents can be viewed.

What I've tried so far.
Gravity: the ball bounces a couple of times and sort of rolls around the floor
Directional Force: the ball starts to bounce to the right but does not want to come back because of said directional force
Gravity + Directional Force: Ball bounces out of control and actually flies out of the cube its in.
Keyframed: manually animated the ball, but looks terrible.

Here is a video of what the original demo looks like & my interpretation via animated gif.

Here is one of the scenes that I had better luck with :)

Any suggestions would be appreciated.

Physics will require the proper surface properties on both the ball and the object it is interacting with. To set them, select the objects in the Instance tray, and then at the top of the screen choose the Effects tab. There should be a Physics heading with a pulldown menu with various presets.

The other thing to remember is that the Directional force can be keyframed. You can keyframe the direction that it is coming from by changing the orientation of the avatar in the Assembly room. You can also keyframe the force level as well, even drop it to zero. That way, you could give the ball a little nudge, by increasing the force, and then turn it off.

You could also add a bounce modifier to the ball itself (in the modifiers tab, hit the +sign and from the dropdown select Behaviors, Bounce is the top one), so that the only thing you really have to keyframe is where it is going from left to right, and it depending on the bounce settings of where the floor is, how long the bounce is, and how high it's bouncing, all the bouncing will be handled by the ball itself.

Not sure exactly what you're looking to reproduce, but there are a few settings you need to be sure of if you want stuff to bounce.

First, you select the bouncing ball and choose physics for its motion. Then, put in some values for initial velocity to make sure the ball starts off with some speed. Maybe 5 or 10 feet per second in the X and Z axes.

Under Scene/Physics use the default gravity. And a low collision distance.

Then, for both the box and the ball make sure they are set to a very high Bounce and very low Friction. Maybe try 100 and 0, respectively.

That should give you something like the video below.

If you want to make it appear slow motion, just do that in your video editing program.

Thanks for all the suggestions everyone. Very much appreciated.

I'll try them all.

I've also lowered the gravity and had a slow motion bounce.

Yes, I understand that physical simulation can seem the only solution, but there are certain animations which require a manual control.
Here an entry which I had carried out for a challenge on Carrarators and impossible to realize with the physical engine.
I was resigned to use graphics of the timeline, and that was much easier.
