I have created a wall using a cube in Unity. Now I want to create a door in it.
How can I make a door in that cube?
Consider that the cube is automatically generated, so i have to generate the door in a C# script.

1\$\begingroup\$ I think it is not. Please consider that the door has to be auto-generated: so there is a coding part, not only modelling part. \$\endgroup\$– EagleOneCommented May 12, 2016 at 18:08

\$\begingroup\$ The cube mesh is automatically generated? Or it's a prefab with a cube mesh? You need to know how to cut a hole in the cube, and put a door model inside the hole? \$\endgroup\$– HouseCommented May 12, 2016 at 18:12

\$\begingroup\$ The world itslef is completely autogenerated from code. It has a cube prefab with its cube mesh. Yes, I have to cut the cube and put a door model in it \$\endgroup\$– EagleOneCommented May 12, 2016 at 18:13

\$\begingroup\$ Right, so how is it different from cutting a hole in an existing mesh? Surely you already know how to place the door model once the hole is cut. \$\endgroup\$– HouseCommented May 12, 2016 at 18:14

Unity primitives are not like actual 3D models, they are great for concepts but do not afford much versatility. I recommend that you start with changing your original wall prefab.
- Create an empty game object and in it make 3 cubes.
- Next, arrange the cubes to look like a wall with a space for the door.
- Make a prefab of this object, maybe name it "wall"
Now make a new cube and size it to fit the hole in the wall. Keep an eye on the transform position in the upper right-hand corner.
You should probably make a prefab of the door object as well.
In C# you'll want to create a "public transform door" this will be visible in the inspector. You can then Instantiate the door at the position you need the door to be. That should look something like:
Instantiate (door, door.position, Quaternion.identity);
In the unity inspector you'll want to drag and drop the door prefab in slot that appears as the door transform.
Hope that helps!

\$\begingroup\$ @Philipp I upvoted both the question and answer, because this was a problem I had before, and the solution I used. But your comment is the right thing to do. I wish it was a suitable answer. \$\endgroup\$– Evorlor ♦Commented May 14, 2016 at 5:01
