IMPORTANT: If the simulation above does not render correctly, click 'open in a new window'.

This simulation uses a custom Animal class that carries a custom sensor. One group, the Sheep, carries a Wolf sensor that triggers a COWARD behavior. The other group, the Wolves, carries a Sheep sensor that triggers an AGGRESSIVE behavior.

The result... the wolves chase the sheep. To make things fair, the sheep have a 'wrapWorldEdges' property set to true. When they cross the world boundary, they cross to the other side. Wolves however bounce off the world boundary.

Play with the various properties to affect the simulation.

• Adds mouse input to control World gravity.

• Add pause, reset and step forward playback controls.
• Add camera control.

• Add a resize event and handler to System.
• Add a devicemotion event and handler for mobile browsers.
• Update Item.step() to limit item velocity.
• Add 'bounciness' property to Item.
• Extend SimpleSim.Item to custom objects (Pebble and Boulder).
• Add 'borderRadius' property to Item to render round objects.
• Add 'angle' property to Item to render rotation.

• Add applyForce() function to Item and update Item.step().
• Add 'wind' and 'thermal' properties to World.
• Add 'mass' property to Item.
• Add Item.checkWorldEdges() function to keep items inside browser viewport.
• Use a cache vector in Item.applyForce() as an optimization.

• Add Vector library.
• Add acceleration property to Item.
• Add velocity property to Item.

• Add style rules in main.css
• Use modernizr to detect css transforms support.
• Create a css text string to use for positioning items.
