Camera Zoom in Turret View

Ezekiel

hexplorer do the same job, and have a “matrix” theme (black/green) by default lol^^ (don’t forget to click on view/simple data types)

I dunno whether I broke it or I’m just missing something fundamental. xD

EDIT: Image wasn’t working for me, so made into a link. :S

Looks like you didn’t get the updated version.

Bobthemanofsteel

facepalm
That’s a Bob mistake. >_>

Thanks.

Here’s an update that might do what you mean by zoom in, by switching to a negative z coord. Note that zooming in a lot plays havoc with the camera speed. I’ve also maxed it out at 500k.

@Bob: If by reverse/invert you mean swap the meaning of the wheel direction, then patch the DLL at 0x1009, 0x7D->0x7E and 0x107C, 0x7E->0x7D.

Awesome work Adoxa, thx.

void Zoom( void )
{
  if (*wheel_state < 0)
  {
    if (*TurretCamera < 0)
    {
      if (*TurretCamera > -500e6f)
	*TurretCamera *= 1.5f;
    }
    else if (*TurretCamera < 10)
    {
      *TurretCamera *= -1;
      TurretCamera[8] /= 2;			// yaw_rotate_speed
      TurretCamera[9] /= 2;			// pitch_rotate_speed
    }
    else
    {
      *TurretCamera /= 1.5f;
    }
  }
  else if (*wheel_state > 0)
  {
    if (*TurretCamera > 0)
    {
      if (*TurretCamera < 500e6f)
	*TurretCamera *= 1.5f;
    }
    else if (*TurretCamera > -10)
    {
      *TurretCamera *= -1;
      TurretCamera[8] *= 2;			// yaw_rotate_speed
      TurretCamera[9] *= 2;			// pitch_rotate_speed
    }
    else
    {
      *TurretCamera /= 1.5f;
    }
  }
}

What do i have to change for changing the max zoom from 500k to 50k and the value of zoom from 1.5 to 1.2 ?
Just wanted that ppl cannot zoom out too far and make zooming more “smooth”.

Seems i cannot find the correct hex values in the dll

Thx in advance

cheers

You’ll notice I got the distance wrong and actually used 500,000K, so that wouldn’t have helped.

002024, 0.666667f = zoom in factor (1/1.5)
00202C, 500e6f = max zoom out
00203C, 1.5f = zoom out factor
002040, -500e6f = max zoom in

Thx a lot Adoxa

Yes, thanks.

Here is a fresh video.

Near the end I zoom in on some npcs. Notice that they reach the extent of their life at 2.5k from me and disappear, heh. But also notice the cool effects of being able to clearly hear their speech and even engine sounds.

The only ‘bug’ I can report is that the program ‘remembers’ the zoom factor. If you have zoomed to 20k and then leave zoom and fly around a bit, when you go back to turret view you are still zoomed at 20k and disoriented until you unzoom back to your ship to catch your bearings.
Is there any way to have it reset to the ship when you leave turret view? Maybe not possible, but still an excellent addition adoxa!

Here’s another update. When you enter Turret View, it will remember the current values; on exit, they are restored. The speed is halved every -10k, which helps a little.

002028, 200000f = max zoom distance
00202C, 10000f = zoom movement holding Shift
002030, 1000f = zoom movement holding Ctrl
002034, 100f = zoom movement holding Alt
002038, 10f = zoom movement holding Shift+Ctrl
00203C, 1.1f = zoom factor
002040, 0.5d = negative distance speed adjustment PART 1
002050, 0.5f = negative distance speed adjustment PART 2

OMG, that is just incredible. Nice work as always.

Here’s the latest version - after seeing what Freeworlds does, you can now move up/down, as well. It’s still not as smooth as FW, though. I’ve included a readme, this time, too.

w0dk4

Well, here is the turret zoom code of Freeworlds if you’d like to integrate it (this is called on rendering any frame):

bool bReloadTurretView;
float fTurretViewMulti = 1.0;
float fTurretViewTargetMulti = 1.0;
float fTurretCameraOffset[3] = {0, 0, 0};

void TurretZoom(CAM_DATA* camera_setup, float fInterval)
{
	// special turret cam zoom

	if(bReloadTurretView)
	{
		// load turret offset data 
		fTurretCameraOffset[0] = camera_setup->fCameraOffset[0];
		fTurretCameraOffset[1] = camera_setup->fCameraOffset[1];
		fTurretCameraOffset[2] = camera_setup->fCameraOffset[2];
		// reset multiplier
		fTurretViewMulti = 1.0;
		fTurretViewTargetMulti = 1.0;

		bReloadTurretView = false;
	}

	float fMultiDiff = fTurretViewTargetMulti - fTurretViewMulti;
	fTurretViewMulti += fMultiDiff * fInterval* (float)2.5;

	camera_setup->fCameraOffset[0] = fTurretCameraOffset[0]*fTurretViewMulti;
	camera_setup->fCameraOffset[1] = fTurretCameraOffset[1]*fTurretViewMulti;
	camera_setup->fCameraOffset[2] = fTurretCameraOffset[2]*fTurretViewMulti;
}

And in the input hook:

case USER_WHEEL:
			{
				// up or down?
				int* iMWheelFlag;
				iMWheelFlag = (int*)0x061684C;

				if(*iMWheelFlag < 0) // up
				{

						fTurretViewTargetMulti *= (float)1.1;

and so on

I find it kind of amusing at how similar the code I hacked out looks to that….

not surprising I guess.

Ezekiel

thx for the updates, and for the code delivery

It will work fine with the last zip
And with the code it is easier to try to learn how to do that…

Thx

The server hosting my site finally got some free space, so here’s the latest version, incorporating the render update (where I use the camera’s accel_speed, rather than 2.5) and processing options (at least, it processes options for me, there’s a chance it might not work for anyone else).

cata123

Adoxa , the options from arguments do not work on windows 7 64 bit.
On windows xp works normal .
I have```
TurretZoom.dll max=6500000 large=1.2

All other features like zooming in and out works nomal .

Edit : my mistake , i didn`t had latest version.

adoxa

If it works on Windows 7 64, I guess it would be safe to assume it works everywhere, and I can remove the patched-in value. I might use it more often, too…

cata123

Yet it works on 7 64bit .
I had 1.4.0 but with the 1.4.1 works good .
Its kinda confusing with those versions released so fast, even i checked the website adoxa.110

DwnUndr

Good work adoxa for this one

It will be in the next UnderVerse release. I limited the range to 20 k so it couldn’t be used as an exploit at our ‘Beat the Bomb’ event. What it will be used for is all of our fighter events so people on the sidelines can see more of the fighters than just specs moving around.
