Building Tips

Physics in AW works on the principle of one object colliding with another, with the resultant impact doing things that resemble what happens in real life. So if you throw a ball at some bottles, for example, the bottles will fall over, and the ball will roll around a bit before stopping. You can adjust all this using the physics in the Action box in the object properties box. The pictures below show some of OzySEO's swinging doors. The commands that make them work are beside the pictures of the doors in bold type. The commands are placed in the Action text box in the object properties box.

One of the elements that he makes use of is the 'avvel' option. This stands for AV Velocity, and it allows a persons's AV to kick or throw a ball, or in this case to open a door just by pushing on it. If you have done elementary Newtonian physics, you will understand the concepts of velocity, force, mass and the like, and how they interact. To get more details on Physics, be sure to check out OzySEO's commands on all his physics objects. You should also go to the AW Wiki page that explains about how the physics engine works. Additionally, the AWSchool has a tutorial on using physics at awschool 19n 158w 0.01a 180.

This picture shows some basic details about OzySEO's use of physics. They are all used in his illustrations below.

This shows a single door that when pushed by an AV will open and swing back and forth after.
On the single opening door:
create collider mass=.1 avvel, hinge pin="0 1 0" limit="180 .01",color white global

Here is an example of a swinging gate, with the hinge on one end.
On the wide gate:
create collider mass=.01 avvel, hinge -2 0 0 pin="0 1 0" limit="180 .01",scale 1 .5,color white global

This picture shows a wide rotating door with the hinge in the middle, corresponding with the Y axis.
On rotating door:
create collider mass=.01 avvel, hinge pin="0 1 0" limit="180 .01",scale .82,color white global
