Detailed Description

This area covers terrain functions. Use as terrain.function(); You will obviously require a terrain in the scene to be able to use these lua commands. For more information on how these functions can be used please visit the User Manual - http://www.chi-ad.com/Skyline/SDN/

float terrain::getHeightAtPoint	(	int	posX,
		int	posZ
	)

Get the height of the closest vertice defined by a world space position on the x and z axis. Y is not used as terrain is always Y oriented.

Parameters

posX	: This is the X Axis position in world space where you wish to return the information from.
posZ	: This is the Z Axis position in world space where you wish to return the information from.

Returns

height : This is a float value of the height found.

Here is a Small Example of how to use this function:

function onInit(objID)
    height = terrain.getHeightAtPoint( 10, 20 );
    sky.print("height: "..height); -- will print something like: 0,0.5,1, 2 10, 20 etc...
end

string terrain::getSurfaceAtPoint	(	int	posX,
		int	posZ
	)

Get the user definable surface name set from within the terrain editor panel. This is not the texture name, if you require that; then please use terrain.getTextureAtPoint(x,z);.

Parameters

posX	: This is the X Axis position in world space where you wish to return the information from.
posZ	: This is the Z Axis position in world space where you wish to return the information from.

Returns

textureName : This is a string value that is returned from the funciton.

Here is a Small Example of how to use this function:

function onInit(objID)
    surfaceType = terrain.getSurfaceAtPoint( 10, 20 );
    sky.print("surfaceType: "..surfaceType); -- will print something like: grass, sand or rock.
end

string terrain::getTextureAtPoint	(	int	posX,
		int	posZ
	)

Get the texture surface that is visible on the terrain at a given location. If you want to get the generic surface type; then please use: terrain.getSurfaceAtPoint( x, z );.

Parameters

posX	: This is the X Axis position in world space where you wish to return the information from.
posZ	: This is the Z Axis position in world space where you wish to return the information from.

Returns

textureName : This is a string value that is returned from the funciton.

Here is a Small Example of how to use this function:

function onInit(objID)
    textureName = terrain.getTextureAtPoint( 10, 20 );
    sky.print("textureName: "..textureName); -- will print something like: grass.dds, sand.dds or rock.dds
end
