Change agent colour during execution

[douglasbandeiraivo]

I've seen that I can change some agent attributes like velocity and radius using actions and events, but I didn't find out how to change the agent colour after something happens, for example because of a change of state or because of being in some region of the environment. I tryed to do it changing the agent class inside an event, but it didn't work. Could you tell me how could I do it?

Short answer: I've got nothing for you.

Long answer: visualization is a layer on top of agent visualization. In fact, all of the visualization artifacts are in a different library than the core Menge simulation code. Currently, the visualization of agents is hard-coded.

It's been long an intention of mine to make the visualization configurable akin to how the simulation is configured. That's one of the reason that there's a sceneV.xml file. However, currently, the only thing you can configure is camera, lighting, and the like.

However, if you want to hack some code, you can do the following:

1. The class you want is VisAgent. It draws the little cylinders. Right now the logic for picking a color simply looks at the class id and maps it to a color (in a really, truly, horrible way). If you gut that function you can define an (r, g, b) triple based on any logic you like.

Ok, I understand. Thank you for the reply. Em ter, 3 de mar de 2020 21:34, curds01 <notifications@github.com> escreveu:
