We will show you how to write your own scripts using a simple example. We assume that you have installed a scripting folder and its location is:
'C:\Users\yourusername\Documents\20simscripting'
Of course you can use own location. We will copy a 20-sim model to the scripting folder and write a script that will open this model in 20-sim and run a simulation.
| 1. | Copy the example model FastManipulator.emx to the Octave\tutorials folder. E.g copy: |
'C:\Program Files (x86)\20-sim 5.1\Models\Examples\Drivetrains\FastManipulator.emx'
to
'C:\Users\yourusername\Documents\20simscripting\Python\tutorials\FastManipulator.emx'
| 2. | Open a text editor (e.g. notepad) and enter the following lines: |
import controllab
xxsim = controllab.XXSim()
xxsim.connect()
xxsim.open_model('FastManipulator.emx')
xxsim.process_model()
xxsim.run()
xxsim.disconnect()
| 3. | Save the text file as: |
'C:\Users\yourusername\Documents\20simscripting\Python\tutorials\myscript.py'
| 4. | Open 20-sim. |
| 5. | Open IPython. |
| 6. | In IPython, change the local working directory. Type in the command line: |
cd 'C:\Users\yourusername\Documents\20simscripting\Python\tutorials'
| 7. | In IPython, run your own script. Type in the command line: |
run myscript
Now you will see the model being loaded in 20-sim and a simulation being run.
In the tutorial folder there are more scripts. Use these as a template for writing your own scripts and follow the guidelines below:
Create your own subfolder inside your scripting working folder. This allows you to update the 20-sim scripting files when new versions of 20-sim are released.
You can find help on scripting functions in the 20-sim Editor by selecting Help - Python Scripting API.
