(This document covers version 1.5.2.1 of the 'Explode' behavior, current as of 2005-Feb-11)
Description
This behavior simulates an explosion from an object when the mouse is clicked on it.
The behavior should be attached to a component/group, where it listens for mouse clicks on all of its children. When a child is clicked on explosion vectors are calculated for all other children on the group and they are animated for the explosion. This behavior is recursive so it will animate models within subgroups independently. All calculations are done with global transforms so the explosion vectors should be consisten through sub-groups.
The
Power
property needs to be modified based on the relative distance between objects. If no objects move when the explostion occurs, in the scene, increase the power. If the objects disappear immediately, then decrease it.
The
Depth
property (if not 0) is great for making explosions come right at the screen or away from the screen.
Basic Properties
Power
The amount of TNT in the explosion.
Impact
The impact radius of the explosion, used for calculating the velocity decay over distance.
