Is there a way to create a custom gameobject?

Hi I just started working with unity, and I want to port a game that I made in XNA a few years ago over as a startup project. I was wondering is there a way to create a custom gameobject that I can use to make reusable tile maps? I have looked all over the internet for a solution, but haven't found anything.

 

What do you mean by "custom gameobject"? You create GameObjects in Unity by either instantiating prefabs, or using the GameObject constructor.

I want to be able to select a custom created gameobject that I create my selff. For example I would have a tile map as a game object.

 

I am not sure but maybe this is what you want, you should create your custom model in any 3d modelling software, bring it to unity and make a prefab of it and use it as you want.

 

You can create an empty gameobject, and fill it with whatever you want in it.
