Interface iTerrainCallBack

Description

The client application creates objects deriving from this interface to enable PathEngine to work with a client side representation of surface detail such as a height field for terrain.

Defined in SDKRoot/code/externalAPI/i_pathengine.h.

class iTerrainCallBack
{
public:
    virtual ~iTerrainCallBack() {};
    virtual float getHeightAt(int32_t x, int32_t y)=0;
};

The virtual destructor is included just for good general programming practice.
Destruction remains the responsibility of the client application - PathEngine will not call this virtual destructor.

Methods:

getHeightAt		This method is called by PathEngine to obtain the height of the terrain layer corresponding to this callback at specified x and y coordinates.
getHeightAtWithPrecision		An alternative version of the height query taking extra float parameters for precision components of position.

Refer to Working with Terrain for an explanation of the terrain callback system.
