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
|

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
|
