Hi all :)
Would it be possible to use .roq videos as Radiant textures? Kind of like the water texture, but instead of deforming the texture, somehow play a video on it. I've been searching and apparently it's possible in some Q3-based games like Star Wars: Jedi Knight, but I'm not so sure about cod2 (although it's based in q3). As I read it has something to do with shaders, is it possible to implement such custom shaders like this I post below in cod2? If so, know any good resources I can take a look on how to do it? Would appreciate it :)
P.d. I saw there are shaders in the materials folder, but how did they make the actual material file that is used in radiant and is "linked" to the shader which animates it? I see no option in asset manager for that :confused: (I mean, I can make the texture but how to link a custom, or even a stock shader?)
Thanks in advance :)

You can play .roq files, like the CoD2 intro sequence when you first start the game, but only fullscreen.
You can use atlas-textures to play 'videos' or more gifs.
However you have to export every frame of the video into such an atlas texture.
I've done it with something like 144p resolution or even smaller, as these textures grow really big really fast.
It its possible - yes, but not really practical. -
25th July 2020, 16:49polloYeah, I know it is possible to play a full-screen .roq video and back in time I used a similar technique of playing gifs, exporting every frame and playing with hide() show() in script (maybe you mean the same with the aliax? :confused:).Quote:

Thanks for the reply :) -

I think I kind of remember now.
It was done as an effect, not as a texture, so placing and scaling can be abit tricky.
Lookup how smoke or fire effects are done, they use an 'atlas'-texture, something like this:

You basically have to export your video clip into this format and fiddle around in the EffectsEditor to display every frame. -

Ty for the clarification :) I will try doing that. Any other knowledge about this is welcome :)

I've played with CoD2 shaders several years ago, the only thing I managed to get to work was changing the speed of the scroll-texture on xmodels, as far as I can remember. Not even the yellow-pulsating glow on objective-textures changed colors. I gave shaders a couple of hours/days to try to modify them and getting the CoD engine to accept them, but I did not 'understand' them well.
CoD4 got those TV's that display a short video, I remember recreating these without much success. -

add a anglestoup(origin1.angles) at the end of your playloopedfx:
That should fix the upside down stuff.PHP Code:playLoopedFx(level._effect["dog"], delay, origin1.origin, dist, anglesToForward(origin1.angles), anglesToUp(origin1.angles));
-
1st August 2020, 23:34pollo
yea I tried it too but still the same :/
-
2nd August 2020, 08:11IzNoGoD
What about using this instead:
PHP Code:playLoopedFx(level._effect["dog"], delay, origin1.origin, dist, anglesToForward(origin1.angles), (0, 0, 1));

I tried it but with same result
it's like the fx is played correctly only in the YZ plane and that the playloopedfx function ignores the last parameter for the up vector, because it should work if we provide both vectors
in the XZ plane it gets rotated 90 degrees :confused:
(there's a typo in my op, the buggy ones are fxorigin2/4 like i illustrate below, but anyway, if i rotate the fx in EffectsEd 90 degrees, 1 and 3 become buggy, and 2 and 4 are fixed)
a workaround could be to make 2 different .efx which use the same shader, rotated 90 degrees in EffectsEd; one of them played in all origins of YZ-plane; and the other, played in all origins of XZ-plane, but not rly a beautiful solution lol.
ty for the help :)

Yeah, I remember that something about placing such effects was weird in CoD2..
Do you spawn them with a bullettrace()? How do they behave on non axis aligned surfaces?
Maybe changing the type of the effect can help, there were different kinds for decals like bulletholes and such (just a guess).. -
2nd August 2020, 13:51polloyeah it's definitely a bit weird. I spawn them placing script_origins in radiant with a specific rotation per each one, thus their forward vector is (aprox. for other surfaces) the normal vector to each surface.Quote:

This is how it looks in non axis-aligned surfaces with the current solution.

I played around abit, and spawned the FX on a tag, but it seems it is the FX, it won't change its upward angle
I play around with the FX itself in the Editor, but its a pain in the ass to change it (change, move .efx file to iwd, start game...) it takes ages. And in the FX Editor not even all effects are shown (I cannot see the decals..)PHP Code:init()
{
level thread MonitorPlayer();
level._effect[ "dog" ] = loadfx( "fx/dog.efx" );
precacheModel( "xmodel/tag_origin" );
}
MonitorPlayer()
{
while( true )
{
level waittill( "connected" , player );
player thread MonitorButton();
}
}
vs( v , s )
{
return ( v[ 0 ] * s , v[ 1 ] * s , v[ 2 ] * s );
}
MonitorButton()
{
self endon( "disconnect" );
while( isDefined( self ) )
{
if( self UseButtonPressed() )
{
start = self.origin + ( 0 , 0 , 64 );
end = start + vs( AnglesToForward( self getPlayerAngles() ) , 10000 );
trace = BulletTrace( start , end , false , self );
if( !isDefined( trace[ "position" ] ) )
continue;
a = vectorToAngles( trace[ "normal" ] );
up = AnglesToUp( a );
fwd = AnglesToForward( a );
right = AnglesToRight( a );
p = trace[ "position" ] + vs( fwd , 1.1 );
// PlayFx( level._effect[ "dog" ] , p , fwd , up );
thread TagFx( 7.1 , a , p );
while( self UseButtonPressed() )
wait( 0.05 );
}
wait( 0.05 );
}
}
TagFx( delay , a , p )
{
tag = spawn( "script_model", p );
tag setModel( "xmodel/tag_origin" );
tag.origin = p;
tag.angles = a;
wait( 0.05 );
PlayFxOnTag( level._effect[ "dog" ] , tag , "tag_origin" );
// doesnt affect the FX
tag rotatePitch( 360 , 2 );
tag rotateYaw( 360 , 2 );
tag rotateRoll( 360 , 2 );
tag moveZ( 200 , 7 ); // works
wait( delay + 0.05 );
tag delete();
}

Some experiments with shaders: https://github.com/nonsensation/CoD2-Shader
However, texture atlas seems to be more integrated in the engine itself, no luck on that.
