Rigid Body
13-Now if you play the animation the pins are not falling down because we put the value of zero in the (Center Of Mass) as like in the picture below.
14-when our ball and pins are colliding nicely with each other and you are satisfy that this animation is ok to see more real action in the scene, go to (Solvers>Memory Caching>Enable, as like in the picture below.
15-by enabling memory cache we will be enable to see our animation as real as in the movie clip. now how to do that? First of all select Pins And the Ball, ok go to (Edit>Keys>Bake Simulation click on the small rectangular box, as in the image illustrated below.
16-You should see now (Bake Simulation Options) in the channel box select (Translate) and the (Rotate) boxes by holding left mouse button and drag down to select, and then do this settings in image below.
17-and then hit the (Bake) Button, wait for a while until bake simulation is not done.
18-When you done play the animation now you see Ball is colliding pins very freely there is not interpenetration.
19-to see key frames go to (Edit>Select all by type>Rigid Bodies, as like in the image below.
20-Select now any pins in the scene you will see all the key frames for the selected pin, as in picture below.
21-when you satisfy with your animation and you want to render it as avi, go again to (Solvers) to clear memory from load and the hit just (delete) it, now your memory in clean, as like in the picture below.
We are pretty done with our animation here is the final result of mine in the picture below.
