-This is currently only a tiny prototype to get an idea of what the scripting engine can do/ check it's performance.
-TODO:
-get file manager support for loading scripts
-move scripts to stk-data, etc.
-
-
-Steps to get this working.
-
-==>change stk-code/src/scriptengine/scriptengine.cpp line 254 as appropriate
-(add the required directory)
-Build the game.
-Play the tutorial
-Test by changing the strings in stk-code/src/tracks/tutorial_bananas.as
-
-
-
-
-Steps for creating new scripts/ actions
-Add an action trigger to the relevant track (Either add it on blender and export it / set it up in scene.xml)
-Create a new script with the defined action scene.xml for the action trigger created. (For example, for tutorial_bananas =>
-
-  <object type="action-trigger" action="tutorial_bananas" distance="7.0" xyz="67.90 0.86 99.49" hpr="0.0 -0.0 0.0" scale="7.00 7.00 7.00"/>
-
-action is "tutorial_bananas"
-so the script it calls is, stk/stk-code/scriptengine/tutorial_bananas.as
-
-Make sure the method onTrigger() is defined. Check tutorial_bananas.as for more details
