# MeshesIntersect (mesh_a,mesh_b )

# Parameters

mesh_a - mesh_a handle mesh_b - mesh_b handle

# Description

Returns true if the specified meshes are currently intersecting. This is a fairly slow routine - use with discretion... This command is currently the only polygon->polygon collision checking routine available in Blitz3D.

# Example
