Hey, everyone.

It's been a few years since I've engaged with tgc forums, feels great to be back on familiar grounds. I've owned AppGameKit for quite a bit now but never really had much of a need to explore it since I had a load of other 2d engines I've used for years. Until now when I need a powerful lightweight 3d engine.

When you use a "do loop" you get that while loop in a nice bracket located in the line number label column to the left of the editor. This is very useful for keeping the code in manageable blocks which you can just minimize and maximize to your comfort. It's this feature possible to set up with any piece of selected code? Or is it strictly limited to "do loop" and for loops?

Second question is partially regarding the same topic. I'm setting up my 3D world with a randomly generated terrain. The code will get pretty big but it's only run once. I noticed that you are ale to create more files that are a part of your project. Would I be able to create a separate code file with my game set up fictions and execute that file from within the main game file?

Ah, perfect.

That set me on the right place/
I used #insert instead from the same help page since it executed the code as it inserted the file.

Thank you.

yo, include append the main file, so insert is better.

When the #include appends the file that ran the function, how do you return back to the main file when the code in the included file has run its course? Just #include main file in the end with the second file to return?

the normal flow:

MainLoop()
End

function MainLoop()

do
if ... then exit
sync()
loop

endfunction

without functions from top level u can jump around with goto or gosub.
its also possible to jump inside a function.
from inside a function u can all other functions, similar the commands u are called.

You definitely do NOT include the main in the included file.

Using gosub from the main file to an included file is not a great idea. But it is doable. If you use gosub, you MUST use 'return' when exiting the sub. Otherwise you seriously mess up the call stack.

I highly recommend using functions instead of subs. Using goto should be done only as a last resort.

Using functions allows a clean encapsulation.

I have declarations and functions in external files. I then include them at the top of my main file. I can then call these functions when needed. IIRC you can't have the program run into function declarations so they must always be after your main loop. I also don't have my main loop in a function but at the end of my main file.
