====== Misc Stuff ======

Area where all misc stuff is placed, before proper place can be found them (if any).

====== Default Installation Files ======

  * [[arma:default_files|Default files]]
Default installation files from your DVD.

====== User Interface ======

When using desktop and ArmA resolution of 1024x768 and your user interface image files are 1280x1024 you'll encounter some memory errors and ArmA will crash.

Here is example images in question:
<code cpp>
class RscDisplayLoadMission : RscStandardDisplay
{
	class controlsBackground
	{
		class LoadingPic : RscPicture
		{
			text = "\VTE_objects\UI\VTE_loading-01.pac";
			colortext[] = {1, 1, 1, 1};
		};
	};
};
</code>
To fix this problem, use image resolution 1024 x 1024 (or other power of two resolution I believe).


====== Aircraft Scripts ======

This section describes some basic things about addon aircraft scripts.

This is practical example of setting up F4 Phantom aircraft addon from OFP conversion into ArmA compatible environment.

First we have exhaust smoke script in OFP like this:
<code cpp>
; We know who we are
_plane = _this select 0;

#SmokeLoop
; If we're dead, we can stop smoking
?(!alive _plane) : goto "Exit";
~0.01;
?(speed _plane < 100) : goto "SmokeLoop";

_alpha = 0.16 * ((speed _plane / 900));
?(_alpha > .16): _alpha =.16;

drop ["\ca\data\cl_basic", "", "Billboard", 1, 10, [0,-5,.1], [5-random 10, 5-random 10, 5-random 10], 0, 10, 1, 1, [5,15,40], [[.2,.2,.2,_alpha/10], [.2,.2,.2,_alpha], [.2,.2,.2,0]], [0,.2,1], 5, 5, "", "", _plane]

goto "SmokeLoop";

#Exit
exit
</code>
Now we have ported the SQS script into SQF format which ArmA likes. This is how it looks when its ported:
<code cpp>

private ["_plane", "_s", "_alpha"];

// We know who we are
_plane = _this select 0;

// Alive and with the engine on?
while {alive _plane && isEngineOn _plane} do
{
	sleep 0.01;
	_s = speed _plane;

	if (_s > 100) then
	{
		_alpha = 0.16 * (_s / 900);
		if (_alpha > 0.16) then
		{
			_alpha = 0.16;
		};
		drop["\ca\data\cl_basic", "", "Billboard", 1, 10, [0, -5, 0.1], [5 - random 10, 5 - random 10, 5 - random 10], 0, 10, 1, 1, [5, 15, 40], [[0.2, 0.2, 0.2, _alpha/10], [0.2, 0.2, 0.2, _alpha], [0.2, 0.2, 0.2, 0]], [0, 0.2, 1], 5, 5, "", "", _plane];
	};
};
</code>

Next you need to run this script from your aircraft's config.cpp file. This is used with compatibility to Extended Eventhandlers (XEH) like this:
<code cpp>
class Extended_Init_EventHandlers
{
	class VTE_SomeClassName
	{
		VTE_F4_engine = "if (isEngineOn (_this select 0)) then {[_this select 0,true] execVM '\path\to\script.sqf'}";
	};
};

class Extended_Engine_EventHandlers
{
	class VTE_SomeClassName
	{
		vte_someclassname_smokefx = "if (_this select 1) then {_this execVM '\path\to\script.sqf'}";
	};
};
</code>
And your aircraft is ready to run this smoke script. Notice how the extended_**init**_eventhandlers are used to start the script even if you place the aircraft flying in mission editor. The extended_**engine**_eventhandlers alone works OK if you start the aircraft on ground, so after mission start the engine is started by AI or player.
