Some questions about vJass

[GIMLI_2]

Hi

Question No.1:

I think it is ok to use the following functions, but i dont know if there is a better way:
UnitInventoryCount
UnitAddItemByIdSwapped


Question No.2:

can you read the length of an array?


Question No.3:

How can i get an offset point in vJass?
i did it like this, but i'm not sure if this is the best solution

    local real x = GetUnitX(u)
    local real y = GetUnitY(u)
    local real x2 = GetLocationX(Location(x, y)) + 600.00 * Cos(f * bj_DEGTORAD)
    local real y2 = GetLocationY(Location(x, y)) + 600.00 * Sin(f * bj_DEGTORAD)

thats it, thank you!

Both are non-native functions (BJs), which means you can replace them by their implementation.
List of BJs: https://warcraft.ingame.de/maps/mappedia/Blizzard.j

The implementation of BJs are compositions of jass language elements and native functions.
List of natives: http://warcraft.ingame.de/maps/mappedia/Common.j

Just do a fulltext search for your functions.

can you read the length of an array?

No, arrays always have length 8192.
You can search the array for the last entry by looping through it...

Replace GetLocationX(Location(x, y)) with x. Same with y..
Apart from that its fine.

Thanks for your answers,

If i take a look at the "UnitInventoryCount", it does what i would actually do to check. It loops through every inventory slot and checks if item != null. If so --> counter++
so is it really necessary to make it myself?

No ofc not, you can use it.
I just thought it might be more useful for you to know how to find out these things yourself than having to ask for every single function
