Try to work with the helping elements before looking at the solution…

Helping elements

• we work in training.myscripts.SimpleScript

• you can copy your new data file in capsis4/data/training/ and change the input file name and location by analogy with the existing code

• before script.init (ip), add a line to change the value of ip.regenerationMax to 5

• script.init (ip) triggers the initialisation process (buildInitScene() + initializeModel()), just after, the root step is available

• you can get references to many objects in the simulation by asking script:
  • script.getRoot () returns the root step
  • script.getProject () returns the project
  • script.getModel () returns the model connected to the project (here an instance of TraModel)
  • script.getRootDir () returns the location of the capsis4/ installation directory

• To trigger an evolution, use script.evolve()
• To trigger an intervention, use script.runIntervener (intervener, step)
• To trigger an export, use script.runOFormat (export, step, fileName)
• Check all these methods in the GScript superclass of C4Script

• after script.init (ip), make a loop for 100 years in which you may:
  • run an evolution stage of 25 years
  • trigger an intervention

• Adapt the evolution stage you will find in SimpleScript

• to run the intervention, adapt this code:

import capsis.kernel.extensiontype.*;
import capsis.extension.intervener.*; 
 
(...)
 
// Intervention: cut tree between 5 and 15m height
Intervener thinner = new DHAThinner (DHAThinner.HEIGHT, 5, 15);
step = s.runIntervener (thinner, step);

• keep the project saving at the end of the script to check the result with the DETimeN graph in Capsis' user interface

• compile, then launch the script in the terminal, from the capsis4/ directory

• the commands to launch the script can be found in the comment at the top of SimpleScript

• Open Capsis in GUI mode, and open the saved project, open the DETimeN graph to check the simulation
