Bind a key directly to a script

[ManDay 0]

You either can have a dialog (meaning a full interface with buttons, you cant aim but have a mouse-pointer instead) or you have a resource => meaning the mouse-events are not caught and you can still aim. I guess you cant catch mouse-events when the mouse is not trapped in a dialog.

Ask weedomatic, maybe he got some experience with mouseevents unter ressourcese.

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">_control displaySetEventHandler ["KeyDown", ""]

Using two scripts:

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">

//init.sqf start

keyspressed = compile preprocessFile "keyspressed.sqf";

_display = findDisplay 46;

_display displaySetEventHandler ["KeyDown","_this call keyspressed"];

//init.sqf end

//keyspressed.sqf start

switch((_this select 1))do

{

   //F key

   case 33:

   {

      // What to do ...

   };

};

//keyspressed.sqf end

Some key-codes are also provided on the page above.

Edit: Don't know if this will work with mouse-events -- haven't tested.

Does someone have a simple example of a keypress script inside a mission they could post (i.e., post the mission, not code snippets)?

I just tried what weedomatic suggested (which is straight from the biki), and it isn't working for me. I understand that it is two separate scripts (init.sqf and keyspressed.sqf), but nothing happens when I press any key. I added a hint in the 33 case condition, and added another hint at the top of keyspressed.sqf to see if it ever got into the function at all (it didn't).

So I am perplexed...

Just tested it in a mission with code from this thread and the wiki-page. Mission contains init.sqf and keyspressed.sqf, code follows:

init.sqf:

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">keyspressed = compile preprocessFile "keyspressed.sqf";

sleep 0.5; // Display needs to init itself, so we give it time

if(!IsNull (findDisplay 46)) then {(findDisplay 46) displaySetEventHandler ["KeyDown","_this call keyspressed"];};

keyspressed.sqf:

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">// If you want something to be done on

// any key:

// hint "SOME KEY PRESSED!";

switch((_this select 1))do

{

// Reacts to "F" key only

case 33:

{

hint "F KEY PRESSED!";

};

};

Without putting the init.sqf to sleep for a moment, it wouldn't find the display. May be my machine, don't know.

Weed,

Thanks alot, the sleep delay made it work!

This will be very useful.
