IAgent.h

In practice, rather than modifying/setting all these values explicitly when making a pathfind request, I suggest you set up bunch of constant sets of properties, and use them.

bool avoidObstacles;

uint32 customNavCapsMask;

float dangerCost;

float exposureFactor;

float flightResistanceFactor;

float height;

int id;

NOTE Aug 17, 2009:

float maxSlope;

Only travel if water depth is between min and max values.

float maxWaterDepth;

float minWaterDepth;

IAISystem::tNavCapMask navCapMask;

Kind of nodes this agent can traverse. Expected to normally be set just once when the agent is created.

float radius;

float roadResistanceFactor;

float triangularResistanceFactor;

Basic extra costs associated with traversing each node type. Everything below here could be reasonably set/modified each time a pathfind request is made.

float volumeResistanceFactor;

Additional cost modifiers.

float waterResistanceFactor;

float waypointResistanceFactor;

Quantity the z component should be scaled by when calculating distances.

float zScale;
