Python scripting examples
It is easy to program Simbad with Java and it is even easier to program it with Python. As you probably know, Python is a very powerful language particularly suited for Artificial Intelligence and Computer Science experiments in general. To execute Python scripts with simbad you need the famous Jython package. Jython is a Python interpreter written in Java, it adds Python scripting facilities to the java language and permit to script directly Simbad classes.
Jython can be downloaded from www.jython.org. Follow Jython (easy) install procedure then edit scripts and launch them with:
For this to work simbad.jar must be on your CLASSPATH
Note: Python scripting is only available since Simbad 1.3.1 version.
A Simple controler
from simbad.gui import * from simbad.sim import * from javax.vecmath import * # a very simple robot controller , derived from Agent java class. class MyRobot(Agent): def initBehavior(self): # nothing to do pass def performBehavior(self): if self.collisionDetected(): self.setTranslationalVelocity(0) else: self.setTranslationalVelocity(0.2) # description of the environment class MyEnv(EnvironmentDescription): def __init__(self): # put a robot self.add(MyRobot(Vector3d(0,0,0),"robot with python")) # put a box self.add(Box(Vector3d(3, 0, 0), Vector3f(1, 1, 1),self)) # launch simbad simbad = Simbad(MyEnv(),0)
