Using variables we can simulate gravitation force on a given model. Let’s take a look at the following code:
s is a sphere having material="rock2"
do 21 times
s.move(y+distance) in 0.05 seconds
First we create a Sphere then we move it 21 times along the Y axis, each time a slightly different distance which is initiated to 0.4 and reduced by 0.04 every iteration. This gives us the illusion of gravitation force applied on our 3d model.
