How to manipulate an agent's specific attribute based on a condition in the model?

[PreetamKulkarni]

I have created senders and carriers as two classes of agents. They have unique IDs. However, I want to change other attributes of a sender or a carrier using the unique id. Is there a way to create object names so that I can use them whenever needed to gain access to the object-specific attributes? I have tried the following but it throws an error: 'str' object has no attribute 'unique_id'

It depends on the scheduler class you are using. With RandomActivationByType, you can access an agent by self.schedule.agents_by_type[agent_class][unique_id_str]. See

mesa/mesa/time.py

Line 244 in dc4d5fc

self.agents_by_type[agent_class][agent.unique_id] = agent

In the following code, will I actually need the object name to refer to its Unique_id?

self.schedule.agents_by_type[agent_class][unique_id]

When I tried to use this in the model, it says it is unable to locate "unique_id". I thought of using "self.Unique_id" but this will work only if I am writing this in the agent's class and not outside the class (Model).

I was able to create a dictionary with the key as the unique id of the agents and the value as the object name which looks like this:

<Abstract_crowdlogistics_model.Senders object at 0x7fd7dabe39d0>.

Now I am able to access Sender's attribute in a function that I defined in the Carrier agent class as shown below:

for i in self.model.Sender_population.keys():
if (self.model.Sender_population[i].Participation_status == "Y" and len(self.model.Sender_population[i].pickup_request_list)!= 0):
self.Potential_senders_to_match.append(i)
