iAgent::setTraverseCostDirection()

Description

Enables a direction to be associated with the traverse cost for a soft obstacle.

Syntax

void setTraverseCostDirection(tSigned32 directionVectorX, tSigned32 directionVectorY);

Parameters

Remarks

An agent's traverse cost direction defaults to [0,0], which indicates that the agent's traverse cost acts on movement in all directions.

Setting this direction to a non-zero vector changes a soft obstacle into a 'directional soft obstacle'.
The traverse cost is then applied only to the component of movement in the specified direction.
Note that no cost is applied to movement at right angles to or away from the specified direction.

The traverse cost direction has no effect on hard obstacles.

Refer to Representing Regions with Cost to Traverse for more details about the 'soft obstacle' functionality.

The traverse cost direction currently associated with an agent can be obtained with iAgent::getTraverseCostDirection().
