Arrays and Me...

[ceedj]

Just wondering if anyone knows how BW's MB sets up arrays.

 

Looking at R*'s code, I see that 0004: (set global int) can either be

 

0004: $Custom = 0

 

or

 

0004: $Custom(1) = 0

 

(this is true with 0006: (set local int) as well)

 

How does the MB do this, converting the (1) into something readable by the SA.exe? I looked at the ReadMe, and it seems he built something into the compiler that calls the proper int opcode (for int, float, string or variable) depending on how you set it up. For example, I think if you type in

 

[email protected] = 0$CustomArray(@1,10i) = 0$CustomArray(1) = 1$CustomArray(2) = 2$CustomArray(3) = 3$CustomArray(4) = 4$CustomArray(5) = 5$CustomArray(6) = 6$CustomArray(7) = 7$CustomArray(8) = 8$CustomArray(9) = 9

 

it compiles as this:

 

0006: @1 = 00006: @1(1) = 10006: @1(2) = 20006: @1(3) = 30006: @1(4) = 40006: @1(5) = 50006: @1(6) = 60006: @1(7) = 70006: @1(8) = 80006: @1(9) = 9

 

 

I want to set up a function to define arrays in the GTASA Hook (there's already a function to reference them...) How is 0006: @1(1) read by the compiler?

 

Thanks!

Ahh, I can explain that (if this is what you asked in you PM, sorry, I didn't understand).

 

If you use $customarray it will obviously be a global array, not a local.

 

Basically, the arrays are an address and an offset * 4 so, using old MB DMA notation:

 

4??(0)

 

Would be an array, starting at DMA position 4 (4 bytes into the SCM, technically in the middle of a jump, but we'll ignore that for now), and 0 positions into it (AFAIK the array positions are all 4 bytes, but there may be data types for larger arrays)

 

4??(1)

 

Is one position in, so it's 4 bytes after 4??, this is exactly the same as 8??, 8??(0) or 0??(2)

 

When the code is compiled I think there is a whole load of new data types for local arrays, global arrays, float arrays, 8byte arrays. I did have a link to a list of the types and some explanations but can't find it atm.

Um, whoops. That WAS kind of silly.

 

Yeah, the answer in the PM was helpful in "getting" it, but I need MB equivilant because normal C/C++ code doesn't play too nicely inside of the hooks "theScript" code. I think I can set up another function using what you explained above, similar to the G (global define) function.

 

I will study this more. Thanks very much!

Ehm... Y not using normal Arrays in C++ ?

Not sure if that is totally correct, made it a while ago.
