Hello everyone, I've been trying to do the "roomevacuation" example. When I add the repulsive force (neighbors and walls) some agents only go to the walls and don´t leave there. I would like to know what I´m doing wrong. Thank you very much. Demo_20.2.0_Salaevacuacion_layout_processflow_sistemafuerzas.fsm
Hi:
Because the SocialForceSystem in the agent module considers the synthesis of various forces, sometimes will appear this situation, which may be due to the balance of forces, so when we do this type of model, we generally add a random force , In order to prevent the situation.
hi, thanks for commenting. Adding the random force helped, but on the right side, one person cannot get out (only one). I used the magnitudes of forces from the example.
In your initialization code, you use the duniform() distribution to set the initial location of each of the agents. Because it is a discrete uniform distribution, some agents begin the model in the EXACT same location as other agents. When two agents are in the exact same location, they will try to avoid each other, but will avoid each other using the exact same forces, so they will always be forced in the same direction.
In your model, the agents who don't complete their task are essentially avoiding an agent that is in their exact same location. You can fix this either by using the uniform() distribution to set their initial location, or by adding a random social force.
Hi @anthony.johnson, thanks for answering my question. I made the requested changes, and it was very helpful, but on the right side, a person cannot get out.
I tested the solutions individually and together, but the result was the same.
We're working on a solution for this. For now, I think you can get around it by either adjusting the A* node size, by increasing the A* path progression threshold in the A* social force, by adding a random force, or by making the corner less sharp (by adding another divider to round it out).
Hi Anthony, thanks for answering my comment. I tried adding dividers at the end of the right side (creating a "U") and it fixed the problem. Thank you very much.
