If you're not sure about the programming part, you're not going to be able to make a game like 'splosion man in construct. The 3D object is for static, non-animated meshes only. Unless you have the programming ability to modify the plugin or write a new one, animated 3D models are not something you can do without crazy math and events. Even then I'm not sure something in 3D that complex is currently possible at all at a decent frame rate in construct.
Don't let quazi's thumb war game fool you. Construct was not built for 3D.
