Method Summary

Modifier and Type	Method and Description
void	applyCollisions(ILevel universe, boolean dynamicsOn) Marks Collision IComponents of applicable IEntities in universe with appropriate collidingIDs
boolean	applyImpulse(IEntity body, Vector J) Useful for debugging but will be deprecated! Applies impulse J to IEntity body
void	update(ILevel universe, double dt) Update Positions of IEntities in universe based on dt and their Velocities

Method Detail

update

void update(ILevel universe,
            double dt)

Update Positions of IEntities in universe based on dt and their Velocities

Parameters:

universe - IEntitySystem containing IEntities with both Positions and Velocities

dt - duration of update in seconds

applyCollisions

void applyCollisions(ILevel universe,
                     boolean dynamicsOn)

Marks Collision IComponents of applicable IEntities in universe with appropriate collidingIDs

Parameters:

universe - IEntitySystem containing IEntities with both Positions and Collisions

dynamicsOn - if true, then impulses are subsequently applied to applicable IEntities (with Mass, Position, Velocity, and of course, Collision)

applyImpulse

boolean applyImpulse(IEntity body,
                     Vector J)

Useful for debugging but will be deprecated! Applies impulse J to IEntity body

Parameters:

body - IEntity with Mass, Position, and Velocity

J - Impulse vector used to calculate the updated Velocity

Returns:

whether J is successfully applied to body (false if body does not have Mass, Position, and Velocity)
