rlm@23 64
rlm@29 65 jMonkeyEngine3 has a plethora of classes which can be overwhelming to
rlm@29 66 manage. This code uses reflection to import all of them. Once I'm
rlm@29 67 happy with the general structure of a namespace I can deal with
rlm@29 68 importing only the classes it actually needs.
rlm@29 69
rlm@306 70 The =mega-import-jme3= is quite useful for debugging purposes since
rlm@34 71 it allows completion for almost all of JME's classes from the REPL.
rlm@23 72
rlm@306 73 Out of curiosity, let's see just how many classes =mega-import-jme3=
rlm@23 74 imports:
rlm@23 75
rlm@29 76 #+begin_src clojure :exports both :results output
rlm@455 77 (println (clojure.core/count (cortex.import/jme-class-names)) "classes")
rlm@23 78 #+end_src
rlm@23 79
rlm@23 80 #+results:
rlm@455 81 : 938 classes
rlm@23 82
rlm@25 83
rlm@34 84 * Utilities
rlm@23 85
rlm@29 86 The utilities here come in three main groups:
rlm@29 87 - Changing settings in a running =Application=
rlm@29 88 - Creating objects
rlm@50 89 - Debug Actions
rlm@29 90 - Visualizing objects
rlm@23 91
