Good questions. BTW, what would be an example useage for arrays in QC?

Can't you test then and see?

I remember reading something about having to wrap them in round brackets in FTEQCC.

Yes it worked. But it didnt do so well with huge functions and stuff like that.

with fteqcc:
.float foo[64];
defines a field array with 64 elements.

self.foo[y] = 5;
sets element 'y' in that array to 5.

As Arkage said, older versions of fteqcc require extra brackets for field arrays: self.(foo[y]) = 5; (which kinda illustrates how fields work internally). The current version doesn't need that, but does accepts the extra brackets if you want to be paranoid.

FTEQCC's arrays are single-dimension only, thus you need to do: [x+y*width] to get 2d functionality.
As Baker said, remember that this creates 64 fields and will increase your entity size and memory footprint by quite a bit, so if you're on an embedded system you may need to be more cautious.

If you're not using any opcode extensions (ie: no -TFTE) then both reading and writing arrays will be emulated with a function call, containing a binary search to get the element, which can be somewhat slow to access.
This means that you cannot define arrays inside another function (you also cannot pass an array from one function to another).

Good example !

Darn, Darkplaces dont like : entity dm_spawns [16];

guess it wont work for an idea I had.

so if i were to use arrays to define stats and inventory it would mean in a multiplayer game since all entities share these fields that each player would carry the same items and have the same stats? if so it seem's arrays would be okay for single player, but what if i wanted to do multiplayer ? how does prydon do these things?

right, but you can't really define player1,player2. it's simply player. unless the engine would handle the difference between players?

baker: so this is how darkplaces would use arrays? e.inv_6_4 = val;

[Arkage]

I just used player1 and 2 as an example. All players are entity's and so every entity has that .herp array. You just have to find the entity for that player.
Unless I misunderstood what you meant?
