split screen after using _IrrSetActiveCamera

[kokoilie]

hello
i'm coding a game in autoit3 which is going to be split screen 2player game
but i can't figure out how to change from the menu camera (the main menu is in 3D and uses _IrrGetCollisionNodeFromCamera to read which menu button is pressed) to the player cameras in split screen

any help will be appreciated, thanks in advance

Use 2 cameras and change the active one when you are in menu/game.

[kokoilie]

the problem is that when i start it it sets the active camera to the one in the menu and then i can't set both player cameras as active

[CuteAlien]

Sorry, not sure about what is the problem. Splitscreen already uses several cameras - one for each screen. Each one is set active before rendering it's part of the screen. You can also replace all those by a menu-camera. Or is the problem the input? I mean there is obviously only one mouse-cursor (as most computers these days have only one mouse), so moving that independent in 4 menues won't be easy to solve.

Try to describe your problem more detailed, so far I don't really get where you are stuck.

ok so first of all i create three cameras

Code: Select all

 
$camera[2] = -10    ;posx
$camera[3] = 0      ;posy
$camera[4] = 50     ;posz
$camera[5] = 0      ;tarposx
$camera[6] = 0      ;tarposy
$camera[7] = 0      ;tarposz
$p1cam[2] = -10     ;posx
$p1cam[3] = 100     ;posy
$p1cam[4] = 60      ;posz
$p1cam[5] = 0       ;tarposx
$p1cam[6] = 100     ;tarposy
$p1cam[7] = 0       ;tarposz
$p2cam[2] = -10     ;posx
$p2cam[3] = 100     ;posy
$p2cam[4] = 60      ;posz
$p2cam[5] = 0       ;tarposx
$p2cam[6] = 100     ;tarposy
$p2cam[7] = 0       ;tarposz
$Camera[0] = _IrrAddCamera($camera[2], $camera[3], $camera[4], $camera[5], $camera[6], $camera[7])
$p1cam[0] = _IrrAddCamera($p1cam[2], $p1cam[3], $p1cam[4], $p1cam[5], $p1cam[6], $p1cam[7])
$p2cam[0] = _IrrAddCamera($p2cam[2], $p2cam[3], $p2cam[4], $p2cam[5], $p2cam[6], $p2cam[7])

then i set the menu ($camrea[0]) as active

my question is how to make the other two work as split screen after i click "Play"

for now i'm using this row

Code: Select all

_IrrSetActiveCamera($p1cam[0]); & $p2cam[0])

but it sets player1's camera as active

[CuteAlien]

Ow ... just seeing now you mentioned autoit3. I fear I can't be of much help there as I know neither that language nor did I knew about that Irrlicht wrapper.

[kokoilie]

so that means i have to improvise some creativity

anyway the autoit's language is (as my brother states, i never tryed to learn C++) similar to C++
also how come you didn't know about the wrapper? isn't it your creation?

[hybrid]

No, we don't provide any wrappers on our own. All the wrappers are community projects, and thus not necessarily known to us. Especially if the wrapped language is of the more exotic ones. So it might be that some support is simply lacking here.

[kokoilie]

ok i found where i'm doing it wrong
*i still don't understand how i didn't notice in the begining*
in the example it's calculating the frames like this

Code: Select all

_IrrBeginScene( 240, 255, 255 )
 
    ; draw the scene on the left
    _IrrSetActiveCamera( $FirstCamera )
    _IrrSetViewPort( 0,0,400,600 )
    _IrrDrawScene()
 
    ; draw the scene on the left
    _IrrSetActiveCamera( $SecondCamera )
    _IrrSetViewPort( 400,0,800,600 )
    _IrrDrawScene()
 
    ; set the viewport back to the whole screen
    _IrrSetViewPort( 0,0, 800,600 )

so that half the screen is shown by one camera and the other by the other
also sorry to bother you

[kokoilie]

once more i'm saying sorry to bother and bring this thread back but i hope i can find some help here about the return values of IrrGetCameraOrientation.
if the autoit wrapper doesn't change it much you should be able to tell me what it returns and how to use it (hopefully display it as degrees)
thanks in advance

I can't really help you, but I was wondering, why do you program something like this in a language like that?
Does it have any sort of advantage for you, over just using irrlicht with c++ ?

[kokoilie]

the advantage (at least for me) is that autoit's help if complete and is easier for me to program in it than c++ (which i'm still trying to learn)

anyway can someone tell me how to use this function's return values or it's used only in the wrapper?

[serengeor]

anyway can someone tell me how to use this function's return values or it's used only in the wrapper?

Looking at the documentation:

Code: Select all

_IrrGetCameraOrientation($h_Camera, ByRef $a_Vector1, ByRef $a_Vector2, ByRef $a_Vector3)

you should probably use it something like:

Code: Select all

 
Dim $forward, $upward, $sideways, $ret
$ret = _IrrGetCameraOrientation($myCamera, $forward, $upward, $sideways)
 

Though I'm not sure, as I don't really know auto it.

EDIT:
There's example in documentation how to use this function ._.
