Thanks @Kyatric, that is exactly what I needed!
I updated the demo. Now you can shoot "bullets" by pressing 'Q'.
I also added the download to both the plugin and the demo at:https://sites.google.com/site/jptarqu/downloads
The name of the download is copperlicht-c2-plugin-v-0.9.zip
Please note that to run the sample capx, you will need to export it to your web server (either local server like IIS express, apache, etc. or to a external server). The reason behind this, is that copperlicht will try to load the external file containing the level made in Coppercube. I could not find a way of embedding that files and the texture files needed by that file in C2's debug server. I personally use IIS express to test demo in my computer.
Another thing to note is that there is a lot of trial and error trying to match the coordinates between copperlicht and C2. For example, for the walls, I used coppercube to design the 3D level and "measured" the units there and put the objects in the same place in C2's layout.
