Making a game engine

Ogre Version: 
1.09
Operating System: windows
Render System: direct 3d
Hello ,
I want to build a game engine out of ogre 3d. Now making a project in ogre is complicated and I want to simplify that. Ia there any way I could make a good editor over ogre or make the project creation process very easy. I mean like drag and drop objects into the scene and then write code.
If the process is reduced to 1 or 2 commands then also its good. Or coukd i make a GUI for that?
Code: Select all
Ogre.log (optional)Top

Is it possible to make a good game engine with ogre. I just want to build a good editor. Or maybe could I just make the project building process easier. Or maybe make a gui for that? Is it really possible?
Or any other way to make things easier and more responsive

You might want to take a look at Ogitor:

Welcome!
Ogre is a rendering engine so its definitely possible, in fact its meant to be used to make an engine, you'll need to bring the rest of the components you'll need, sound, physics, gui, etc.
For example my engine loads everything from blender files so I use blender as my scene/models/materials/physics editor and I use OpenAL, Qt, Bullet, MyGui, etc etc
Be aware that its a lot of work

No I understand that what is ogre or what is ogitor. But what i want is that I want to reduce the anount of code that should be written or the librarues that need to be imlorted while making a project.
Example: a person clicks new project and clicks on the libraries he wants to add and then the project opens up and he can start doing the project.
But could you explain that what all can Ogitor do
Thanks in advance!!

Moreover if you understand what I say. It takes a lot of understanding of code blocks and stuff to install a project or simply to say to setup a project. You need to do a lot. But what I ask is that can I bring this down to few clicks?
Like someone clicks make project then it creates and sets up the project with mingw or something like that.
I just want the process to be smoother and easier and not like copying the tutorial framework and stuff
Thanks in advance

Hi,
building an own game engine is a looong process.
I'm creating an own GameEngine now for 12 years in my spare time.
Its essential to have a good concept, read a lot of books and try out a lot of things.
I can recommend a really good book for you, which can help:
https://www.mcshaffry.com/GameCode/
The keyword is Entity-Component system.
Ogre is a render engine, you also need other libraries like physics, navigation mesh, 3D sound etc.
There are some custom written libraries, if you examine the forum, which to work well with ogre.
Best Regards
Lax

Perhaps you should look into compiling your project with CMake:

Hey grt thanks for it. So if I create a GUI for this I mean that it inits the program and then uses the cmake to compile it then would it work?

Moreover could I use this method to add libraries to it right. To make it easier.

What I have encountered is that building ogre is a difficult task. Specially making a project in it.
What I want is that can I bring that process down to like Unity 3d for my users. Where you click new project and then create one and open it.
Moreover like it is in Neoaxis.
I want to know how to do that.
And I tried the ogitor and my cmake is saying that ogitor files are invalid.

I came up with an idea (sorry if I am flooding the forum)
If i make a gui that basically makes a main.cpp file for you. And when you say that you need to add libraries to it. It just adds those specific libraries in it.
Moreover I was thinkibg that it could add a lot of other thibgs to the programs and then save that main.cpp file and the compile it with a compiler.
Will it work?

Hey thanks,
What I was actually thinking is not make my own libraries infact intergrate bullet physics and open ai thats it. I know if I build my own then it will take a lot of time.

You will have to take it slow.
Lax engine took him 12 years to develop.
I am developing one of my own (as a hobby) and its been 5 years and counting.
Read the wiki, and use the forum to research specific topics.
I'm sorry but it does not seem that you will be able to accomplish this so easy and fast.
Perhaps, take a look at this engine (I was able to compile it with MinGW and CMake with no issues whatsoever):
https://urho3d.github.io/
It already has a GUI built-in if I am not mistaken.
And it also has physics and audio ready to go.
Also, take a look at this site:
https://www.gamefromscratch.com/
And check all the libraries and game engines available, perhaps you will find something more suitable.
If you want to stick to OGRE3D, all the power to you. I'm just trying to help.

no.
Your general idea is on the way though. I am in the process of consolidating the various addons in the main repository, so you will be able to choose at cmake time which additional features (physics, audio etc.) you want ogre to have.
However, this will just add some more building blocks for whatever you want to do with Ogre. It will not magically make it a drag and drop game framework like Unity. If you want that, take a look at Godot.

Hey I know about godot actually I said it wrong that I want it like unity. I just want it simple.
What I actually mean:
As you can see to use ogre 3d you need a .cpp file. You have to compile that file.
What I want to do is make a method to generate that file and then give the user the freedom to edit it without any interferences. Moreover after that I may do tge Cmake thing but this is what I meant.

I won't use ogre 3d for this and will create a seperate application
This will just add the very very basic code like the tutorial application.cpp does

Moreover i know it wont become a drag and drop framework. But I just want to make the process easier and not drag and drop.

you can also use ogre from python...

Grt thanks so if I use this method of making a file and theb asking the users to compile it then it should work right
