Hi! First off I'm not sure if this belongs here or in Programming Talk. Anyways, I know how to make an executable using the release mode in VC++ but lets say I have a game engine like FPSC. How would you give the user the option to create an executable?

P.S. This question is really just out of curiosity.

Games are like life, they should never stand still.

Well, you really have two options. First is to learn the assembly language of your platform (x86 for Windows, for example), and then add that in, command by boring command.

That's difficult, but if done well, it's fast.

The other option is just to figure out a file format to save your creation (in the case of a game, the level data, players, etc), and then make a program that can read and run this file. Then, you just have the same program, but a different file.

This is easier, but a bit slower. However, if you do it well, it shouldn't be too bad.

The other option is converting their creation into some other language, such as C++, then using someone else's compiler from within your program.

Hey, that's a great idea! never thought about this, or have something planned, but good to know...

Converting the code would be a pain though. you would need a full keyword file for the language and then a converted keyword file(for each command so for dbp if it saw Sync On then it would find dbSyncOn() in the other keyword file)


among other things it's a pain lol. tried that one time

A more convenient alteration on this idea is to store this file at the end of the engine EXE itself.

You could also use an architecture where you have 2 standard EXE's ... eg. one for your editor and one to run the game...

Instead of generating an EXE file from your editor when a game is finished, generate a batch file of some kind, to pass you "game.exe" file the proper command line arguments to load the game data file....

Would be easier to do that than trying to generate an entire EXE... which is quite complex to do properly.

If it ain't broke.... DONT FIX IT !!!

If you have a engine like fpsc, then i think you can esaily make a button in the editor, that will copy over the engine's exe to a folder, with all data the game(editor map) needs, you could then export all data of the editor into txts. And make it readable for the engine exe, so for example for one world and posistion and scale the editor would export it like this:

world.dbo
0
0
0
100
100
100

Engine would have some sort of read system, not that difficult and export the strings into integers (atoi maybe?) and then you could use it to load up things. Like the engine would load world.dbo and place it at 0 0 0 and scale would be 100 procent.

So basicaly the engine'exe is a game itself, all he does is search and activate.

That would be my way, you can do this for all settings and events in a game.

Hope i helped a bit,

Be careful - I don't think you can copy a an exe which is running because it will be inaccessible. I may, of course, be wrong; it is a good idea for other reasons to have an editor exec separate from a standard engine exe.

That is what i meant.
It will copy the engine exe. But you are working on he editors exe.
