	)

inline

Finds the closest navmesh triangle at the position plus radius. Works in 2D and 3D. Caveat: The result is only a heuristic and not 100% accurate due to simplified calculations to reduce precision issues. For example: in 3D the input position is projected down instead of finding the correct closest position. The search can be performance heavy so carefully choose the radius.

Parameters

Parameters

position	Sample position
regionMask	Region mask
inclusive	Use inclusive `true` when you want include the border and the vertices of the triangle

Returns: Triangle id or -1

◆ FindClosestTriangleFast()
