| How are arrays stored in memory? Last night, I was successfully able to create an array containing 26905 elements. (one for each land grid square on Altis)
| |
| <code>[] spawn
| |
| {
| |
| _number = 0;
| |
| _test = [];
| |
| _brushes = ["Solid","Horizontal","Vertical","Grid","FDiagonal","BDiagonal","DiagGrid","Cross"];
| |
| for "_i" from 0 to 308 do
| |
| {
| |
| for "_o" from 0 to 308 do
| |
| {
| |
| if (!surfaceIsWater [(_o * 100) + 50, (_i * 100) + 50]) then
| |
| {
| |
| _name = format["%1_%2",_o,_i];
| |
| _marker = createMarker [_name, [(_o * 100) + 50, (_i * 100) + 50]];
| |
| _marker setMarkerShape "RECTANGLE";
| |
| _marker setMarkerSize [50,50];
| |
| _marker setMarkerBrush (_brushes select (floor random (count _brushes)));
| |
| _marker setMarkerColor "ColorRed";
| |
| _number = _number + 1;
| |
| _test pushBack _marker;
| |
| };
| |
| };
| |
| sleep 0.01;
| |
| };
| |
| hint str _number;
| |
| player setVariable ["holy_shit", _test];
| |
| _test = nil;
| |
| };</code>
| |
| I was able to confirm that the array did actually contain my elements with:
| |
| <code>'''//ran from debug console'''
| |
| _array = (player getVariable "holy_shit");
| |
| _array spawn
| |
| {
| |
| for "_i" from 0 to ((count _this) - 1) do
| |
| {
| |
| hintSilent (_this select _i);
| |
| sleep 0.05;
| |
| };
| |
| };</code>
| |
| I thought it was strange, at first, that my game didn't crash from running out of memory, but after doing some quick math everything seems to be in order. ASCII uses 7 bits and I was saving 5-6 character strings so:<br>
| |
| 7 * 6 = 42<br>
| |
| 42 * 26905 = 1130010 '''bits'''<br>
| |
| 1130010 / 8 = 141251 '''bytes'''<br>
| |
| 141251 / 1024 = 138 '''[http://en.wikipedia.org/wiki/Kibibyte kibibytes]''' or 141251 / 1000 = 141 '''[http://en.wikipedia.org/wiki/Kilobyte kilobytes]'''<br>

Should there be any comment here or in random about randomly selecting an array element given the rounding rules? Or am I being ridiculous?
e.g.
_myArray select ((random (count _myArray)) - 0.5)

tmp = [];
val1 = [1,2,3];
val2 = [3,4,5];
tmp = tmp + [val1];
tmp = tmp + [val2];
tmp = tmp - [val1];
not working, why? I've also tried "tmp = tmp - val1;" --MessiahUA 16:14, 19 September 2008 (CEST)
