Here is a C++ type definition:

	typedef struct NewtonCollisionInfoRecordTag
	{
		typedef struct NewtonHeightFieldCollisionTag
		{
			int m_width;
			int m_height;
			int m_gridsDiagonals;
			dFloat m_horizonalScale;
			dFloat m_verticalScale;
			short *m_elevation;
			char *m_atributes;
		} NewtonHeightFieldCollision;
	} NewtonCollisionInfoRecord;

Here is my BlitzMax version:

Type TNewtonCollisionInfoRecordTag
EndType

Type TNewtonHeightFieldCollisionTag Extends TNewtonCollisionInfoRecordTag
	Field m_width
	Field m_height
	Field m_gridsDiagonals
	Field m_horizonalScale#
	Field m_verticalScale#
	Field m_elevation:Short Ptr
	Field m_atributes:Byte Ptr
EndType

Can I pass a BlitzMax type like this to a dll using a Byte Ptr parameter? Will it work? So far my results do not seem correct.
