Save and restore simulations

Save and Restore simulations

Last version of GAMA has introduced new features to save the state of a simulation at a given simulation cycle. This has two main applications:

• The possibility to step forward and backward in a simulation,
• The possibility to save the state of a simulation in a file and to restore a simulation from this file.

Save a simulation

experiment saveSimu type: gui {

	reflex store when: cycle = 5 {		
		write "================ START SAVE + self " + " - " + cycle ;		
		write "Save of simulation : " + saveSimulation('saveSimu.gsim');
		write "================ END SAVE + self " + " - " + cycle ;			
	}	
	
	output {
		display main_display {
			species road aspect: geom;
			species people aspect: base;						
		}
	}	
}

Restore a simulation

experiment reloadSavedSimuOnly type: gui {
	
	action _init_ {
		create simulation from: saved_simulation_file("saveSimu.gsim");	
	}

	output {
		display main_display {
			species road aspect: geom;
			species people aspect: base;						
		}
	}	
}

Saved simulation file type: gsim
