Lol, now there's screens of that little demo I put together. Anyways, I had a go at making a pendulum, and put that in this demo(in the attached dba file). I also had fun trying to make bridges, and made a function that makes a bridge. If anyone cares, here's what the parameters of the bridge function mean. The bridge function is:
make_bridge(start_num,x1#,y1#,z1#,x2#,y2#,z2#,width#,height#,sections,mass_per_link#,group_id,freeze,texture,tip#)
start_num - the first object the function should use for the first link of the bridge
x1#,y1#,z1# - the x,y and z values of the start of the bridge
x2#,y2#,z2# - the x,y and z values of the end of the bridge
width# - the width of the bridge
height# - the height (or y size) of each link of the bridge
sections - the number of links in the bridge, more than 2 links is recommended
mass_per_link# - the mass of each section
group_id - the newton id of the links
freeze - weather or not the brigde should autofreeze when it's not moving
texture - the texture used for each block
tip# - the "tippiness" of the bridge, standard value is 1.0, the greater the tip# variable is, the more tippy the bridge gets when you walk on it.
With the pendulum, you can "push" it by pressing the explode button while riding it.
I can't wait for the next version
