Question by MaleficVision · Jul 06, 2012 at 10:45 AM · android3d

I have a few questions(Newbie here)

So yeah,I'm new to Android App Development and 3D Game Dev.

My team and I have this project that needs to be done in 3D. It's a Digital Map of our campus with basic functions like SEARCH,How To Get There(Specific instructions) etc. The feature that Unity3D would help us create for our app is the Free Roam function wherein we would like the users have a first person view of the whole campus like in an FPS game where they could see the campus like walking around it.

So we've searched for 3d software that would work well in Android and Unity3D is the most recommended.

Now here are my questions: 1) Unity3D is a 3D rendering software which can build output files as a .APK right? Does that mean I can create the whole app in Unity3D? If yes, how can I see the source code? Is there a code editor in Unity3D?

2) If I decided to create only models and animations in Unity3D how can I use them in my android app? for example,I create an android app wherein I type in a building name,and the Unity3D model of that building will be displayed. How can I achieve this? Can you give me some links for tutorials?

3) Are SCENES in Unity3D considered the same as an ACTIVITY in Android Apps? If yes, then I can create a Scene which I will use as a splash activity then another scene containing the other parts of the app?

I don't know if I posted this in the right section. I'm new here in the forums as well. And if this is the wrong Section, I'm deeply sorry for posting it here.

And I'm thanking in advance for those who will answer my questions.
Good day to everyone!

I don't know if I posted this in the right section.

It would be best to post on forums ins$$anonymous$$d. But since you are new, we will be merciful.

BTW have you considered this could be the perfect opportunity for some "augmented reality" trickery.

if you simply look around on the app store, there would certainly be 1000s of apps that a,ount to guiding you around a campus, using "AR".

something to consider !

The quick answers to your questions ...

(1) Unity does NOT happen to include a text editor. Use any text editor. I recommend textWrangler.

(2) Unity IS NOT a model making program. you are thinking of Maya or Cheetah3D. I recommend Cheetah3D

Again, Unity is a "game engine". You can and should read what a "game engine" is on Google, Unity is ot a model maker.

It would be like confusing photoshop with a swimming pool. They are quite different.

If you're interested in modelmaking, buy Cheetah3D and enjoy a couple years learning to make models, awesome.

Professional who use Unity3D -- game engineers -- simply BUY models from model-makers. It's exactly like buying music from a musician, do you understand?

Model-makers are cool guys and girls with long hair who drink beer and who make models. Those people make models using softwae called "Maya" or "Cheetah3D". That process has no connection at all to a game engine, or being a game engineer - writing code and so on for games. Game enginers USING models (which they buy from a model-maker) in a game engine. Similarly game engineers USE music which they buy from people like Sting.

Makes sense now?

Every person on this here list has now explained this about 1000 times to new questioners :)

(3) (a) Forget about android and make normal iPad apps. Just joking. (b) "Activity" etc is totally irrelevant. (c) Yes in unity, your intro could well be what is called a "Scene" in Unity.

(4) What you describe in your second paragraph is exactly and precisely what you do in Unity.

I have to alert you you are a long way from "throwing that together."

Suggest you actually GET UNITY -- IT IS FREE -- and start reading tutorials.

If you have any further simple questions, post them here as separate questions, phrase them succinctly.

I am sure people do not MIND answering basic questions but you will learn much more by clicking the download button.

What about $$anonymous$$onoDevelop? I think that is what he meant by code editor.

It's not actually a game. We are developing an android app. It is supposed to be our school's Digital $$anonymous$$ap/Brochure where in it will showcase the different structures,buildings,history,courses offered etc.and give directions on how to get to a specific place in the campus. This is actually for our thesis.

The free roam is just a feature that we thought of having because our panelists suggest that we make the target audience of this project for visitors.

Actually I've been watching a few tutorials...I've managed to have a terrain with mountain and trees already and a FPS Controller which I use to move around. And I'm actually having fun doing this haha :)

Anyway, we don't have models yet. We're also in the process of requesting for building plans/blueprints so that we can just hire someone to do the models and build it in unity as a whole map.

And since we're on a deadline we are considering this thing like in google maps 3D view, where some of the places in Google $$anonymous$$aps are textured in 3d using photos of all the sides of that building. And as i've researched on how people do those models...I learned that they used Google SketchUp to do that.

Can that be used here in Unity?

(1) I believe you can use SketchUp models in Unity. I encourage you to ask a separate A about that you will probably get some help. Search forums too.

(2) You say "so that we can just hire someone to do the models" That could cost quite a lot of money (ie, it could take man-months of work). That would actually be a good question on here, "How much would it cost to have models built of the of buildings on our campus, here's a rough photo showing the buildings."

(3) The tutorials are great. Just FYI $$anonymous$$any people (wave!) don't like using the terrain system, and it would be totally irrelevant to you. (You'll have to build a model of your landmass, exactly like you'll have to build models of the buildings.)

(4) You mention the "quickie" approach of sort of using rough boxes, and pasting a photo of your buildings on each side. Yes, that can work, assu$$anonymous$$g the look is what you want. You have to sort of "go for" a comic or $$anonymous$$imalist look, does that make sense? It's a mater of getting a good look.

Are you already or do you have in your group a 1st rate Javascript programmer? i guess it will be a struggle if you additionally have to learn that from srcatch. How long do you have for this?

Also note that Unity for Android is not free of charge. It will cost you $400 to get the Android plugin.

Note that they are student licence available at Studica. But I don't see here licence for iOS or Android. Maybe you can contact Unity sales for your particular needs.

Thank you for the answers. About the Plugin,we are aware that it's not for free so maybe we will contact unity for that. :) Thanks again! :)

Regarding your Android issue --

(A) unity are pretty clear cut about not giving student, help, charity etc licenses, so I wouldn't worry about that overly.

(B) a bigger issue. Let's say you get the models and idea figured out and make the project perfectly. You can then click "Build" and it will run beautifully as a normal app on a normal $$anonymous$$ac computer.

You can completely show it to your advisors, show it to everyone, test it, and so on and so forth.

Note, this is exactly what you would do during development. At the "last $$anonymous$$ute" you would just click the "build to Android" button.

So, simply tell your advisors, "oh, it's $1500 for an andoid license, so we won't actually build it to android, here it is running on a normal macbook, great huh?"
