6 years ago Hi, having worked on the Unity environment, it seems to me that it is possible to do a lot of things with Gama on a Unity scene. However, I think we need to set and fix the border between what will be done with Gama and what will be done whit Unity. I think it is possible to develop a kind of generic Unity scene, on which a Gaml model can create and manage objects as needed, without touching Unity.
So far, I have investigated several aspects and I would like to have your feedback on this subject, by mean of this discussion, to fix the points to achieve. To have a preview of what I have done, you can run the model TwoPlayersWithSceneBuilding.gaml and the scene (EmptyScene) in the repo: YoucefSklab/UnitySceneWithGama
Basically, possible actions on a scene are:
- Create/manage objects.
- Assign a value to a given field in a Unity object.
- Request the value of a field of a Unity object
- Call any method, with one parameter (or more) of a Unity object. Methods with several parameters should be written following a specific scheme.
- Assign a value to a property of an object (Color, position, rotation,... ).
- Manage the movements of a Unity object;

It would be great (and would open many new opportunities) to display a Gama Simulation in a high level 3D renderer like Unity. I am not saying that the current java2D or Opengl are useless they are a must have but they show some known limit in term of realistic and performant rendering.
By having a look in the experimental repo of GAMA I see that @ysklab seems to work on a Unity project link to GAMA: ysklab/Scene-GamaUnity
Maybe this can answer to some of the question raised in this issue?
I copy/paste Youcef answer in this issue:
Hi, I have started working on this idea since a couple of weeks. The right repository is: ysklab/UnitySceneWithGama, which consists of a Cube-Collector game, where a Gama agent moves a ball in a Unity scene in an attempt to collect cubes. After having the total collected cubes reached the needed number (the latter is indicated by the Gama agent at the beginning by mean of notification subscribe message), a notification message from unity to Gama agent is sent, thus, ending the game. Other functionalities are available. I will describe how the whole things work soon.
