Interacting with the game environment

If you don’t want to roll your own picking, the Lemur GUI library supports scene picking as well as GUI picking.

Lemur Gems #3 : Scene picking

Lemur has a robust picking subsystem that uses JME’s standard ray collision code. In this Lemur Gem, I add simple mouse picking to the app already built in Lemur Gem #1 and Lemur Gem #2 When you initialize Lemur’s GuiGlobals, it automatically adds the MouseAppState that does scene picking. It also adds the guiNode and rootNode to the pickable scene roots automatically. This demo uses that automatic setup. It is also possible to use the MouseAppState without the rest of Lemur but for simplic…

Edit: and note, you don’t have to use the GUI part if you just want picking… but putting a button on the screen is really easy with the GUI part if you decide to try it.
