The new overhauled Playmaker bindinds will be shipped as a separate package, so this lets me finally implement a great jumping-off point for new users: included samples. The following samples are now included and can be individually added to or removed from your project:
Let's have a mental exercise: image something shameful you have done, it doesn't have to be the most shameful thing, just something that you really are not proud of should do. Now imagine putting it in a sealed box where it will be rotting and festering for years. Now imagine having to open that box, slowly lifting the lid as the rancid smell starts creeping out of the box. That is how it felt when I opened up the old Playmaker support.
When I released version 1 and version 2 of Grid Framework there was no real way of separating libraries. You had to dump everything into your project in one assembly. Using namespaces prevented name collisions, but you still had things like examples or documentation bloating up your project and there was no way of expressing dependencies. Since then Unity has introduced its own package system, which will solve many of the problems I have had in the past.
