In my pedestrian model, I have two ped types: RegPed (regular pedestrian) and SpePed (special pedestrian). In the RegPed interface, I have attached a polygonal node to represent 'field of vision' as shown:
Within my model, the RegPeds (green) are walking towards a target line using a PedGoTo block. On the way there, they may 'see' a SpePed (red) inside their field of vision as shown:
When this happens, I want the RegPed to abandon its initial PedGoTo command (named goToExit) and instead adopt a different command via the exit port. I have put the following in the field of vision node's interface to cancel goToExit when the node closes after a SpePed enters it:
However, the following problems arise when I try to run the model:
Is this happening because the field of vision node is within the RegPed interface and not the main agent interface? Are there any solutions which result in the same desired functionality?
Here is my model hierarchy:
