Wander_3D

[hana-gharrad]

Hello all,
I'm trying to use the wander in 3D moves (Gama 1.9.1). However, I got wander_3D does not exist!
Am I missing something? Here is the code:
species agent2 skills: [moving, moving3D] control:simple_bdi { float view_dist<-150.0; float speed <- 2#km/#h; rgb my_color<-rnd_color(255); init { do add_belief(ready); } aspect basic { draw circle(30) color: my_color border: #black; draw circle(view_dist) color: my_color border: #black wireframe: true; draw name at:location color:my_color; } rule belief: ready new_desire: fly strength: 3.0; plan do_fly intention: fly{ do wander_3D; } }
Referring to the documentation. I need just 'moving' in the skills but I added both. The agents does not move in 3d, it moves only in 2d (when I change to wander).

I appreciate your help
Kind regards,

Hi @hana-gharrad that's actually a good question. When the 2 skills are used simultaneously it seems that the wander used by defulat is the wander in 2D. What about using only moving3D skills in your model?

[hana-gharrad]

Using only moving3D as skill. The error message says: The variable wander_3D is not defined or accessible in this context. If I use wander with moving3D as skill. The agent does not move.

If I am not wrong wander_3D doesn't exist anymore indeed. The idea is that if you use the movingskills wander will be in 2D if you use the moving3D skills the wander will be in 3D.

Is it possible for you to share the full model so I can test it?

Sure, here is the code. Thank you. So the z_max will not be applicable anymore?

Hello, I know it's old but just if someone is having the same problems. Here the issue was that your world is a 2d shape and thus 3d moving is not possible, you can fix that by creating a cube instead of a square.
