Scaleform and mouse cursor

[edx76]

Hi,
I'm new to UDK. I've read that using Scaleform, you can create menus and HUD for a game. Few things I'd like to know:
1 - Is it possible to display a mouse cursor on screen while in game with scaleform, specially with a game extending from ut classes? The only tutorials I know about that are X9 production tutorials (which doesn't use scaleform and doesn't work for me with classes extending from UT classes - dont know why) and pieces of codes from RTS Framework, which work fine but doesn't use Scaleform.
2 - Is it possible to get mouse world coordinates (deprojection of 2D mouse cursor coordinates), using the same kind of code as I read in RTS framework or on X9 production site?
When I say: "is it possible?", I mean: is there a video showing it or a piece of code available on these forums I could learn from?
Any information much appreciated. Thanks.

[xGallox]

1- Is possible, you can do it in the same way it is done in any flash application.

2- Is possible, and the X9 tutorial is a good solution. You can find more about mouse projection in this tutorial http://unrealmindset.wordpress.com/2010/04/29/mouse-projecting/

[edx76]

Thanks a lot. I already saw your blog and thought it was very interesting work but I didn't saw this article. I'll read it.

This is how my Scaleform mouse works.

In Flash:

1. A new movieclip symbol with imported bitmaps as the cursor images.
2. An instance of this movieclip on the main stage in it's own layer.
3. Following AS in the first frame of the mouse layer:


import flash.external.ExternalInterface;

// Hide normal "Windows" pointer.
Mouse.hide();

var mouseListener:Object = new Object();

mouseListener.onMouseMove = function ()
{
// Set the cursor instance position to the mouse position.
MouseCursorInstance._x = _root._xmouse;
MouseCursorInstance._y = _root._ymouse;

// Tell our UnrealScript about the new mouse coords.
ExternalInterface.call( "ReceiveMouseCoords", _root._xmouse, _root._ymouse );

updateAfterEvent();
};

Mouse.addListener(mouseListener);

In Unrealscript:

A GFxMoviePlayer class for the HUD movie:


class Tds_GFxHud extends GFxMoviePlayer;

var int MouseX;
var int MouseY;

function Init( PlayerController PC )
{
Start();
Advance(0.0f);

SetFocus( false, true );
}

// This is called from Flash.
function ReceiveMouseCoords( float x, float y )
{
MouseX = x;
MouseY = y;
}

DefaultProperties
{
bDisplayWithHudOff = false
bGammaCorrection = false

// Path to your package/flash file here.
MovieInfo = SwfMovie'TrGfx.TrHudMain'
}

The HUD class the uses the movie:


class Tds_Hud extends UDKHUD;

var Tds_GFxHud HudMovie;
var class<Tds_GFxHud> HudMovieClass;

simulated function PostBeginPlay()
{
super.PostBeginPlay();

HudMovie = new HudMovieClass;

HudMovie.PlayerOwner = Tds_PlayerController(PlayerOwner);
HudMovie.SetTimingMode( TM_Real );
HudMovie.SetViewScaleMode( SM_NoScale );
HudMovie.SetAlignment( Align_BottomCenter );

HudMovie.Init( HudMovie.PlayerOwner );

// When using scaleform these seem to be set to 0?
SizeX = 1280.0f;
SizeY = 720.0f;
}

singular event Destroyed()
{
if( HudMovie != none )
{
HudMovie.Close( true );
HudMovie = none;
}

super.Destroy();
}

function Vector2d GetMouseCoords()
{
local Vector2d mousePos;

mousePos.X = HudMovie.MouseX;
mousePos.Y = HudMovie.MouseY;

return mousePos;
}

event PostRender()
{
local Vector2D playerMouse;
local Tds_PlayerController tdsPlayer;

tdsPlayer= Tds_PlayerController(PlayerOwner);
playerMouse = GetMouseCoords();

Canvas.SetDrawColor( 255, 255, 255, 255 );

Canvas.SetPos( 10.0, 10.0 );
Canvas.DrawText( "Mouse: X:" $ playerMouse.X $ ", Y:" $ playerMouse.Y );

// ** Can do the deproject etc. as shown in tutorials here on the values from GetMouseCoords().
}

DefaultProperties
{
HudMovieClass = class'Tds_GFxHud'
}

Great! That's exactly what I'm looking for.
Which classes do you extend from for your pawn, playercontroller and gameinfo?
Is it possible for you to deproject cursor coordinates to get world mouse position?

[Doublezer0]

or you could extend my simple Flash Scaleform Cursor class to suit. I like The methods you used there Kitese for the situation you required. Nice

[edx76]

Thanks, guys. I'll have a look at all this stuff.

[Hytek]

Unfortunately it doesnt seem like SetFocus is in the september build of udk, what can we use instead?

[zero4]

1. A new movieclip symbol with imported bitmaps as the cursor images.
2. An instance of this movieclip on the main stage in it's own layer.

Is there any chance that someone can tell us how to do that? :) Steep by step. I will be grateful!

Hi,
I'm having trouble with the default MovieInfo,
I get this error when I compile

Z:\UDK\Development\Src\RC\Classes\RCGFxHud.uc(36) : Warning, ObjectProperty GFxUI.GFxMoviePlayer:MovieInfo: unresolved reference to 'SwfMovie'RC.menu''

Z:\UDK\Development\Src\RC\Classes\RCGFxHud.uc(36) : Warning, Invalid property value in defaults: MovieInfo = SwfMovie'RC.menu'

While I've definitively added my menu.swf and menu.fla in :
[game directory]/UDKGame/Flash/RC/

I had import swf with command 'udk gfximport RC/menu.swf' with no error.

Here is my GFxMoviePlayer Class

class RCGFxHud extends GFxMoviePlayer;

var int MouseX;
var int MouseY;

function Init(optional LocalPlayer LocPlay )
{
LocalPlayerOwnerIndex = class'Engine'.static.GetEngine().GamePlayers.Find( LocPlay);
if(LocalPlayerOwnerIndex == INDEX_NONE)
{
LocalPlayerOwnerIndex = 0;
}

if( MovieInfo != None )
{
if( bAutoPlay )
{
Start();
Advance(0.f);
SetPriority(1);
}
}
}

// This is called from Flash.
function ReceiveMouseCoords( float x, float y )
{
MouseX = x;
MouseY = y;
}

DefaultProperties
{
bDisplayWithHudOff = false
// Path to your package/flash file here.
MovieInfo = SwfMovie'RC.menu'
}


Please if anyone can help, I need a mouse T.T
Thanks !

[Nanorock]

Ok, I've managed to get rid of warning and error during compilation.
And now it work.
I had to import my .swf with udk content browser, and move it in the UDKHUD package in order to correctly have the .swf loaded via unrealScript. Why my package didn't work ... don't know -_-
Anyway I've got a mouse ! cheers !

[dpsygnet]

Anyone got it to work with the november release ? i got an error about


...\Classes\PZOGfxHUD.uc(6) : Error, Redefinition of 'function Init' differs from original

:(

[Nanorock]

Look at init function of the parent ... it's not the same ! And it must be the same ;)

[dpsygnet]

I did that previously and got a whole lot more different errors in frontend. Can you post your working code so i can compare ?

[dpsygnet]

Figured out that they removed Player Owner, invalidating most of the code. Anyone can rewrite one using the new GetPC function ? i tried but failed after many trial and error.

try this

HudMovie.Init(HudMovie.GetLP());
not PC! Because function Init(optional LocalPlayer LocPlay) in GFxMoviePlayer class and your init function must be same or you get error

[dpsygnet]

I did thank you but i still have a lot of errors

..\PZOGfxHUD.uc(11) : Error, 'SetFocus': Bad command or expression

Managed to get no error or warning but the mouse wont show. Do i need to add something in my maine game .uc file ?
Here are my files, can anyone help me fix the problemes ?

notes: the flash actionscript is the same as from first page. also I imported the swf in the UDKHUD package as someone suggested that it wont work elsewhere.

I'm not certain whether it will fix your problem, but I had an issue that my mouse cursor would not track the mouse until I had this in my HUD.uc:
function vector2D GetMouseCoordinates()
{
local Vector2d mousePos;

mousePos.X = HudMovie.GetVariableNumber("_root._xmouse");
mousePos.Y = HudMovie.GetVariableNumber("_root._ymouse");

return mousePos;
}

[srv]

the flash actionscript is the same as from first page. also I imported the swf in the UDKHUD package as someone suggested that it wont work elsewhere
AS works fine, just put your .swf file to 'UDK\UDKGame\Flash\NameOfYourHUDPackage\'
Also all content used in yours swf should be in a folder 'UDK\UDKGame\Flash\NameOfYourHUDPackage\NameOfYour SWF\'

I will try that thank you, but it still doesn't fix the playerowner problem. I replaced the HudMovie.Init(HudMovie.GetLP()); but it gives me error about all the other line refering to Playerowner. I changed them to GetLP but i still have more and more error.

Anyone can simply take my code and try to get it to work, and post it here so that everyone can get a functional mouse cursor ?

[srv]

this works for me:
GFx class


class GFxWHUD extends GFxMoviePlayer;

var int MouseX;
var int MouseY;

function Initialize()
{
Start();
Advance(0.0f);
}

function ReceiveMouseCoords(float x, float y)
{
MouseX = x;
MouseY = y;
}

DefaultProperties
{
bDisplayWithHudOff=FALSE
bEnableGammaCorrection=FALSE
MovieInfo=SwfMovie'WUI.HUD'
}


HUD:


var GFxWHUD HudMovie;

simulated function PostBeginPlay()
{
super.PostBeginPlay();

if (HudMovie == None)
{
HudMovie = new class'WGame.GFxWHUD';
HudMovie.Initialize();
}

SizeX = 1024;
SizeY = 768;
}

function vector2D GetMouseCoordinates()
{
mousePos.X = HudMovie.MouseX;
mousePos.Y = HudMovie.MouseY;

return mousePos;
}


If it doesn't help, give me your code, I will look, than I can help

[dpsygnet]

Thank you, nearly worked :)

was getting a error
(21) : Error, 'mousePos': Bad command or expression

had to add
local Vector2d mousePos;
above mousepos, no more error now

Still cannot see my mouse through :(


My .swf is located in ///\Development\Src\PZO\Flash

my gfx class says
MovieInfo=SwfMovie'PZO.PZOGfxHUDCursor'

and in UDK in my content browser the path of my swf is

..\..\UDKGame\Flash\PZO\PZOGfxHUDCursor.swf

is it supposed to be alright ?

also i created my flash file as Actionscript 3 , should i select As2 instead ?

am kind of lost as to why it is not working.

[lordshtzu]

Thank you, nearly worked :)

now i get the error
(21) : Error, 'mousePos': Bad command or expression


on your HUD class are you extending UDKHUD or something else ?

That's just because he forgot to declare mousePos at the top of GetMouseCoordinates, just add:


local Vector2D mousePos;

at the top of GetMouseCoordinates.


My .swf is located in ///\Development\Src\PZO\Flash

The swf needs to be in UDKGame\Flash\PZO I think, and that's where you should import it from into your package in UDK. That is pretty much how my files are set up and it works fine.

srv's code works well, but I do have a different problem with it. Despite having:


SizeX = 1024;
SizeY = 768;

And despite the fact that the resolution of the window is indeed 1024x768, the coordinates I get from the ReceiveMouseCoords function are in the range of 800x600 (which is what the flash movie is authored in).

This breaks things like DeProject, although I can work around it by scaling the coordinates like so:


mousePos.X = HudMovie.MouseX / 799.0f * Canvas.ClipX;
mousePos.Y = HudMovie.MouseY / 599.0f * Canvas.ClipY;

Where Canvas.ClipX is 1024 and Canvas.ClipY is 768.

Anyway, like I said I can work around it, but I was wondering if there's a way to get the coordinates out of flash in the resolution of the game, not the flash movie, since it seems like this would be a pain when supporting mutliple resolutions.

[dpsygnet]

I double checked and my .swf is actually in UDKGame\Flash\PZO

I redid my flash as actionscrupt 2 but it still wont work. It's frustrating, i have no error , the problem could be anywhere and everything !

anything special in the way you create your cursor ?
are you changing the resolution of the scene ?
I created a movie clip and imported a .tga, added it to the librarym, added the tga into the movie clip, selected the first frame of the scene, added the actionscript and exported a swf

[lordshtzu]

We just have a movie clip with the cursor image, and in ActionScript on the clip we have added:

onClipEvent (mouseMove)
{
_x = _x + _xmouse;
_y = _y + _ymouse;
}

This should make the cursor show up when previewed in Flash as well, it's from the examples of how to get a cursor to work (in flash).

[dpsygnet]

tryed to replace my flash code with yours and it didn't works :(

Do you have anything related to your mouse in your playercontroller, pawn, main classes ?

I did a quick kismet to play my swf cursor just in case it was a stupid error of it being invisible and i can see it, but it's not moving..

[lordshtzu]

Nope, nothing like that, it works for us when previewed in Flash as well....

[srv]

also i created my flash file as Actionscript 3 , should i select As2 instead ?
only AS2 ! AS3 not supported for now as i know

I have created flash HUD the same size as a standard window of start UDK - 1024х768 (these sizes I have applied for SizeX/Y)
dpsygnet, your swf file should is on this path: '.\.\UDKGame\Flash\PZO\'
and content is:
'.\.\UDKGame\Flash\PZO\PZOGfxHUDCursor\'
If all is alright, also yours .png (only PNG, not TGA) file of the cursor with the correct identifier it should be imported itself to library at import swf.
After all it problems with my code shouldn't be.
I think that your problem in an incorrect content path and file extension (should be .png).

lordshtzu, while coordinates in uc are transferred from AS these coordinates will be only concerning the sizes of working area swf

and for Action Script this is my mouse listener and mouse drag code:


import flash.external.ExternalInterface;

Mouse.hide();

var mouseMoveListener:Object = new Object();

mouseMoveListener.onMouseMove = function()
{
ExternalInterface.call("ReceiveMouseCoords", _root._xmouse, _root._ymouse);
updateAfterEvent();
};

Mouse.addListener(mouseMoveListener);
startDrag("cursor_mc", true);

cursor_mc is instance of my cursor movie clip located manually in frame

sorry for my English :)

Are you still struggling? If so, do you still have this line in your HUD class?

HudMovie.SetViewScaleMode( SM_NoScale );

I also had issues with my mouse cursor until I removed that line.

[nemirc]

Hello everybody D:

I got my utterly well-drawn cursor to show up in the play window, but I can't move it?I compiled with no errors, but no matter if I move the mouse like crazy, the cursor just stays there.

Any idea why this is happening? D:

[collix]

Had the same problem like nemirc, but then I figured that I should edit the Actions of my scene (unselect everything and press F9) instead of editing the actions of my movieclip.

[Syndrome9001]

So, I've been trying for about 4 days to get this to work. I've tried various ways and am currently stuck with the error:

"Warning, ObjectProperty GFxUI.GFxMoviePlayer:MovieInfo unresolved reference to 'SwfMovie'MyIsometricGame.MyHud"

as well as "Invalid property value in defauls: MovieInfo=SwfMovie'MyIsometricGame.MyHud'

I made this account just to ask for help because I'm absolutely LOST!

I was just going through the X9Productions tutorial for making an Isometric Game and (obviously) got to the mouse part, which is no longer valid.

I made my cursor (as a .PNG), imported it in to Flash and use's Srv's actionscript and Instance Name (bottom of page 3) and the mouse functions in flash perfectly. I placed the .Fla and .Swf in UDKGame > Flash > MyIsometricGame (I also tried just adding it in the UDKHud folder) and even added the .PNG to a subfolder with the same name as the .Fla/.Swf.

As for my HUD and GFxMoviePlayer script, I also tried using the code provided by Srv.

Do I need to add anything else in other scripts? I have "HUDType=class'Iso_Hud'" in my GameInfo script, but do I need anything else added? (keep in mind, all the scripting before what Srv provided is what's on the X9 website.)

Is there any chance someone could make a full tutorial that's functional with the latest UDK? That would be amazing and probably get rid of my massive headache, lol.

Thanks in advance.

in which file i want to place all this code, guide me i am new but not much new and I also want this in my game to make cursor so please if some one clear me would be greatly appreciated.

[Matt Doyle]

@yaziii -

From what I can tell...

The first code block should go in a FLA/SWF file called: TrHudMain.SWF and this file should be saved in the package: TrGfx

The second code block should go in an UnrealScript class called: Tds_GFxHud.uc

The third code block should go in an UnrealScript class called: Tds_Hud.uc

[Matt Doyle]

@Syndrome9001 -

It is hard to say for sure what is wrong, without more details, particularly I'd need to see your code. But, it looks like your code is referencing a SWF file that does not exist in the package you say it does.

You need to read this to learn how to import a new package & SWF into UDK:

http://udn.epicgames.com/Three/ScaleformImport.html#Importing%20SWFs%20into%20UE3

Essentially - save your SWF file in a folder called TrGfx in the Flash directory of your UDK game directory. The Flash directory already exists. So create the folder TrGfx in there, then save your SWF inside that.

Then, inside UDK Editor, press Import button in Content Browser and import the SWF file.

\UDKGame\Flash\TrGfx

The UnrealScript files should be saved in this folder inside your UDK install:

\Development\Src\UTGame\Classes

what should I name the movieclip of mouse and also instance name???

[nemirc]

Had the same problem like nemirc, but then I figured that I should edit the Actions of my scene (unselect everything and press F9) instead of editing the actions of my movieclip.

I did exactly that, but the mouse does not move. Unless it doesn't work in PIE but in PoPC only?

[collix]

Well, it works all the time for me, maybe you need to set the Gametype for PIE to your game in Worldproperties of your level?

[Tjommi]

I cant seem to make this thing work either. Currently my code looks like this. When i run my game i cant see the cursor from flash, also the coordinates from Canvas.DrawText doesnt update either and is stuck on 0.0000, 0.0000.

I got 2 layers in my .fla file, one "actions" and one "scene" and the AS code is posted in the first frame of "actions".

any suggestions?

Edit: Ive also tried to change the actionscript to what "srv" suggested but when i do the "startDrag("Crosshair", true);" i get the message "Error: StartDrag of invalid target 'Crosshair'".
i tried to convert the object i had placed on the scene to a "symbol" movieclip and give it the name "Crosshair" but that didnt change anything.

[Tjommi]

Figured it out. I didnt import my .swf right so the script didnt access it. works now.

I've made my cursor using Doublezer0's mouse cursor class, but I've got a problem.. Since I load my movie on texture, not on hud, I want my mouse to be moved only when I'm around that BSP object. Right now cursor on that screen moves whenever I move, and clicks whenever I click, even if I'm gazillion miles away. How can I change that?

[Blade[UG]]

You'll need to play with bCaptureMouse in it to get that to happen

[Kaldrick]

Adding a bCaptureMouse=false line at the defaultproperties gives me nothing. Same with bIgnoreMouseInput = true.

Trying to make this work, but I am not sure what I should edit the error-line to be.

Change TDS_PlayerController with your PlayerController derived class.

[HadHa]

Change TDS_PlayerController with your PlayerController derived class.

Im fairly new to unrealscripting (Had a first glance at it 4-5 days ago) -
Could you be more specific?

I tried using my UDNPlayerController (which I dont think gives much sense) and the PlayerController from development/source/engine - None of them was really helping.

Any help would be appreciated.

[HadHa]

Still trying to figure this out.
Anyone at all?

[Rosicky]

Hi, Sorry to bring up an old thread but does anyone have any working examples for this? Maybe including the Game and PlayerController classes? I've got my flash working separately (using the Scaleform Mouse gem thing) but when I try to include it with my existing scripts it just doesn't seem to work. The X and Y Coordinates are in the top left but nothing actually happens with the mouse and no cursor shows.

Thanks for your help!

[nemirc]

You could try studying (or even modifying) the UDKFrontEnd flash file that ships with UDK. As I recall the entire mouse thing only requires 2 lines of code or so.

[Rosicky]

Thanks, I've had a go but I still cant get it working. The Flash file I was using was from the Scaleform Mouse gem so I doubt it could be that which was stopping it running correctly.

All I wanted was to have a mouse button move the player - I had it going last year using tutorials but now I've come back to UDK all the tutorials are out of date.

EDIT: Is there any bugs with this? I tried using script from http://zombpir8ninja.blogspot.com/2011/03/d-battlemap-using-udk-fixed-hud.html and got it working okay however I changed a few things and broke it so replaced my edited code back to their original one. Now the mouse will not work at all, the cursor just sits there? It was fine about 10 minutes before and I haven't touched the actual flash files?

EDIT2: Scratch that - I needed to add the following back in:

mousePos.X = CrosshairMovie.GetVariableNumber("_root._xmouse");
mousePos.Y = CrosshairMovie.GetVariableNumber("_root._ymouse");

;)

[Rosicky]

It's me again :rolleyes:

Can anyone tell me if there is alot more work needed to get a mouse button working for navigation?

The mouse works okay for the player rotation although its not central (north and south are out in x), however my main problem now is getting a mouse button to work for movement instead of WASD etc..

Thanks for the help

I followed Allar's cursor tutorial and now my mouse works quite fine. Here is the tutorial: http://www.youtube.com/watch?v=6VkP7JgYH4k


He uses startDrag function but the problem is, mouse lags a bit when imported to UDK. Anything to fix that?
