[Unity] How to Use Physics.OverlapCapsule

Capsule and Cube Collider

You can use Physics.OverlapCapsule to get two Colliders overlapped with a CapsulCollider as above. This method takes the position and the size of a capsule and returns all Colliders overlapped by the capsule.

You can get the Colliders by configuring a Kinematic Rigidbody Trigger Collier and handling the OnTriggerEnter message, but the method is handy.

How to Make JSON Parser Strict

I developed a JSON Parser for C# named DynaJson. It is very strict to the standard of RFC 8259. It accepts all conformant and rejects all non-conformant JSONs except for two exceptions.

One exception is trailing-commas. Another is leading 0 in numbers, for example, 02 and -02. The former is for practicality. The latter is for compatibility with DynamicJson.

JSON's grammar is simple, but carelessly implemented parsers don't accept all conformant and not reject non-conformant JSONs. An excellent article of Parsing JSON is a Minefield shows where mines are in implementing JSON parsers.

Mount Any Windows Folder into Containers on Docker for Windows

In a native Docker environment, you can mount /source in a container host onto /destination in a container by docker run -v /source:/destination and access it from the container.

Well then, how can you mount C:\Source in Windows onto /destination in a container on Docker for Windows? You can't directly mount C:\Source in the VM host into the container, of course.

As the first step, you have to set up C:\Source as a shared folder for a VM when you create it with docker-machine. You can specify the shared folder with the --virtualbox-share-folder option of the VirtualBox deriver as follows.

docker-machine create --driver virtualbox --virtualbox-share-folder=C:\Source:Source
