mesa agents not work the function that put in Class Agents

Question

I try to put an function for the calcule of the venta "self.venta += 10" to verifique the model, but the result not change.

Someone can help me! thanks.

class MoneyAgent(mesa.Agent):

    def __init__(self, unique_id, model,row):
        super().__init__(unique_id, model)
        self.empresa = row[0]
        self.x_coord = row[1]
        self.y_coord = row[2]
        self.venta = int(row[3])
        self.empleado = int(row[4])
        self.zona = row[5]
        
        #defining the owners:
        self.owner = False
        if unique_id in model.owners:
            self.owner = True
            

    def step(self):
        self.venta += 10

Not work the function for the increment of "venta", the result not change:

Answer 1

the poblema is resolved, i forget code to run "model.step()" for i in range(3): model.step() for agent in model.schedule.agents: if isinstance(agent, MoneyAgent): farm_empresa.append([i, agent.empresa]) farm_x_coord.append([i, agent.x_coord]) farm_y_coord.append([i, agent.y_coord]) farm_venta.append([i, agent.venta]) farm_empleado.append([i, agent.empleado]) farm_zona.append([i, agent.zona]) farm_owner.append([i, agent.owner])
