End polygon is not added to polygons array in findStraightPath #153

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
When calling findStraightPath the end polygon is not added to the polygon 
array. Instead it is set to 0. That means that:
straightPathFlags[n-1] = DT_STRAIGHTPATH_END
but
straightPathRefs[n-1] = 0

where n is the number of points/flags/polygons, after the function has returned.

That is by design. The returned polygon describes the polygon which is after 
the vertex, the polygon that was entered to. So the last vertex enters "void".

The feature was added when I added support for off-mesh connections. It allows 
you to match a vertex in the straight path to a off-mesh connection.
