Whistler · **easy way to find the normal vector of the ladder -** 23-07-2004

Code:

g_engfuncs.pfnTraceModel(m_vecWptOrigin, VecBModelOrigin(pLadder), point_hull, pLadder, &tr);

if (tr.flFraction < 1.0)
   // tr.vecPlaneNormal is the normal vector of the ladder now

m_vecWptOrigin is the origin of the waypoint, which is always "outside" the ladder.

pfnTraceModel() means a tracehull which is only blocked by the specified entity ("pLadder").
