It success in (unity ver. 4.7 / monodevelop) but not in (unity ver. 2017 / visual studio)

The error is Line 25 [1] & Line 129 [2] .

Thanks.

Maybe you’re looking for sharedMesh? MeshColliders no longer have a ‘mesh’ value.

129 is self explanatory, that method is no longer supported.

Unity changes over time. If the API updater fails to catch it, you need to figure out what the original methods did / do, and how to map them to the current API.

Always start with the documentation for the classes you are using. Look through all the methods for what you might need in order to accomplish the task at hand.
