I'm having some problems including source files, and not entirely sure what I should be doing. I've made modules in C and Pascal before, so I'm experience with them, but not with db. I dont seem to have any help on them in my help files, so I must be missing some technical docs.

My questions are:
(1) In C and Pascal you have to make include file headers with things like IMPLEMENTATION followed by the names of the functions below. Do you need anything like that in db, or do you literally just have a load of functions in a source file and just include it?

(2) Arrays are automatically global in db, so if I define an array outside of a function, I dont have to pass it to that function as a parameter - it's just global. However, it seems that this isn't the case with an include file. So if I define an array in my main source and then try and access it in my include file, it doesnt recognise it. Is this correct? It also seems you cant pass arrays as parameters, which obviously makes what I'm trying to do impossible.

(3) Whats the exact process I need to follow?

Any help would be appreciated. I know I could just copy and paste all the source into one big source file, but when we hit 10000+ lines of code, its going to get very messy. Also, our group are working via the internet, so ideally we'll be incorporating our individual work together as #included source files to make it much easier to organise it.

Cheers.

1) You can either use the #include statement or add files to the project area.

2) Try putting the GLOBAL command before the array defined in the included file. I dont know about #include, but it should be accessable if you include the file in the project area.

Good news everyone! I really am THAT good...

I've also found that in DarkBASIC Professional, it is best to add the included files to the project using the Files viewer of your project rather than use the #include directive. I had problems compiling and running functions when they were included using the #include statement, probably due to the fact that it was being included twice or something.

Either way, don't use #include in DBPro, just add the new files to your project using the project file viewer window.

#include has never worked for me in darkbasicpro. You just add the multiple sources to the project folder. They are automatically included

I was including the file and using #include. I've managed to mess up everything I was doing before, but I tested something quickly without using #include and it seems it might do the job. I'll give that a go, cheers.

Ok, it appears to work when I stick "GLOBAL" in front of all my array definitions, but I also cant have type definitions in the include file. They have to be copied to the main source, but thats ok.

Still testing, but it looks like all is good.

You shouldn't have a problem with types in an included file - they work fine when I use them - for an example, see the 'Fast A*' code in code snippets.

Forget types! lol. I'm still having problems with variables!

-I have a function "InitialiseCollision()" in my included file.
-First thing I do is run "InitialiseCollision()" in my main source.
-All the array definitions in InitialiseCollision() are all prefixed with "global". e.g.
global Dim BounceCollisionXSpd#(1) as float
-This is compiles fine and works, but whenever I try and reference them from within the main source file, it doesnt work.
Example:
position object 1, SlidingCollisionX#(1),SlidingCollisionY#(1),SlidingCollisionZ#(1)

These variables exist and are defined. It doesnt even say they're not, the actual error is:
"Parameters for "Position Object" do not match format blah blah blah"
Its blatently the right formatting. I can retrieve info from the variable using an assignment statement:
a# = SlidingCollisionZ#(1)
Although I havent tested to see if they're actually successfully holding values.

Basically, I dont know whats going on! Anymore ideas? I dont want to have to assign all my variables into temporary variables before I use them in other statements. I kinda have the feeling the variables wont be holding the values properly either.

I suspect that you are defining your arrays *within* your function in the same way that Raven was declaring his globals within his function.

I suggest you look at the A* code and see how I did it. That uses array, globals and types all over the place, and it all works perfectly whan included

All arrays are global, there is no need to use GLOBAL DIM arrayname()

Rob its good practise to use global & local when describing your values if that is what they need to be.
It also conserves the memory better because the values then have strict rules rather than being open

don't worry my av will probably be going back to Vegeta again soon, it just my character for 7dp up there cause i likes her.
i didn't notice until last night that i've made her look so similar to one of my mates, she was all like "hey this kinda lookes like me" ... i was "oh yeah, wonder why" hehee

i have so many cute friends

lmao... she's nothing like the game character unfortunately, personality wise she is... but she doesn't like guns, can't fight to save her life, she is a vegan (so can just imagine how much energy she has lol).

apart from being looks and smoking the similarities stop there, but i'm hoping to coax her into moving over to the west coast get her into a few things (like MEAT! lol) ... sides its always nice to have a cute girl around the house that isn't like a big sister to me lol

/me shouts out some funny words that you only hear on late night TV.

ARGH! Last night, I decided to collapse my entire game into one source file because of the problems I was having with #include/Add File ...

To be honest, its not exactly a problem with db though, seeing as you can collapse your functions making them one line each, which solves the mess issue. Well, it would if the collapsing of functions worked.
