Is possible to make a Easy Game Maker, that use the capacities of DBPro, the code to make games will be in other language, not a full language just some easy commands, maybe oriented just to some kind of game.
The code will be directly interpreted by a program done in DBPro, and will not be compiled with DBPro. The users will not use any file of DBPro, just the program made in DBPro.

In resume, running the program, players select some option, select they 3D objects files, made some easy code, and get a game…
They can save/load the game they made, as a kind of text file, but they will need always the program to run the game…

Is this legal, or illegal because is a use of a game maker, to program other game maker?
Or I just can program what I want with no limitations, and do with my program what I want?

This doesn’t mean I intend to do this, just a question crossing my mind!

My understand is that this is totally legal, infact several people have already started writting such things although I struggle to see the benefits unless you make it point and click as otherwise all you will do is make a slower and feature limited BASIC in comparison to DBPro.

Sounds as if they could effectively use DBPro's functions without purchasing/owning the produt. That would translate to yes, it is illegal.

No, he says they'd need the program. I think it falls in the category of 'unless-DBS-tells-you-otherwise-it's-just-fine'.

I'd have to say yes, it is legal.
Think of this.
You could make a program that all it would do is read a script.
The script would be the language of the program.
This script would tell the program what type of game it is.
For example a FPS.
It would give the maps, enemies, weapons, items etc...
Now it would have to be very simple FPS, nothing too fancy. I'm talking Wolfenstien 3D or Doom for that matter. That is about as complex as you could get. Maybe Quake1 or Quake2.
But yes, it is possible and legal.
Why.
Because they are not using Dark Basic Pro. They are using your program. You have a right to make such a program since they won't be directly using Dark Basic Pro's functions.
This is basically the same with everyone's level editors, paint programs etc...
So I see no problem for you to do it.

Oh lol, misread it... thought he said he wanted to make a program that lets people use DBP's functions but in a simpler way.

It's no different to what the DB development team did with DB.

This is perfectly legal according to the DBP EULA. However, you obviously cannot include any of the DBP DLLs or DBP compiler.

is it even possible to make dbp complie executables of its own, because without that, making a program which makes programs would be pretty useless.

I dont think you could make DB make executables of its own...but you could have an exe that reads certain data files that describe the game. I think that pretty much accomplishes the same thing.

Absolutely fine. In fact I know of several projects along these lines.

You certainly could get a DBP exe to write its own executables. DBP can write bytes to a file, which is the only necessary feature to make a compiler. Not easy though

But, if this is legal, you could make a program like this:
You can use every command of Dark Basic but give the commands an other name. Than you can let the program output a text file that can be read by an exe that's provided. And than sell the program for $10,00. Than nobody wants to use DB anymore... I know this isn't legal, but where do you put the line between legal and illegal. What can you do, and what can't you do?

@RTSpider.

Wrong. You are NOT allowed to include any of DBP's DLLs in the program that your compiler makes (the 3D engine DLLs, the DBP core DLLs, the 2D DLLs, sound / collision DLLs etc.). This would mean no 2D / 3D engine or any of the core functions etc.

You can effectively add to the back of a .EXE file the script files, thus making it a standalone EXE. I'm not going to say how as I feel this is a disrespect to DBP (and I haven't done it with DBP), but I have done it in VB for a single file installation program and it works like a charm!

There is actually a very clear line stating what's legal and what's not... basically, don't include a single thing for the DBP installation unless you're given permission.

Let me simplify it:

EVERYTHING is legal except:

1) You may not include DBP DLLs seperate from the compiled exe, or provide any option for your program to extract the DLLs and use them elsewhere.

2) You may not include the DBP compiler.
