I'll try sending the pics here

#

#

first pic is the setting for the raw image

second shows what I have in the camera scene

third shows what happens when I build the app

#

The goal is to be able to have the camera in the top third of the screen and have a background around the rest of the image

#

You are aware of windows button + shift + S?

#

Or don't you have discord on your desktop?

zinc bramble Jun 12, 2022, 7:14 PM

#

yes but I also wanted to send stuff from my phone

#

#

I am aware just stupid at times

coral lintel Jun 12, 2022, 7:15 PM

#

Yeah thats more readable

zinc bramble Jun 12, 2022, 7:16 PM

#

Its pretty easy to make it fill the whole screen but Im not quite sure how to make it look good not doing that.

coral lintel Jun 12, 2022, 7:17 PM

#

Can you make your second picture bigger?

zinc bramble Jun 12, 2022, 7:17 PM

#

coral lintel Jun 12, 2022, 7:17 PM

#

And why has the third picture Discord in it?

zinc bramble Jun 12, 2022, 7:17 PM

#

just trying to show the cameras warped

coral lintel Jun 12, 2022, 7:18 PM

#

Ahh

#

What kind of code did you write for this?

zinc bramble Jun 12, 2022, 7:19 PM

#

I copied from a video. I can paste the code real quick one sec

#

coral lintel Jun 12, 2022, 7:22 PM

#

Is this all?

zinc bramble Jun 12, 2022, 7:23 PM

#

yup

#

thats all I have so far

#

it makes and displays a camera and will scan qr codes. the displayed camera just looks warped when I do anything other than filling the entire display with it

coral lintel Jun 12, 2022, 7:24 PM

#

The white box is where you want to show the camera?

zinc bramble Jun 12, 2022, 7:25 PM

#

basically. I would like to be able to resize that white box even more to make it perfectly square. but rn the camera isnt even showing in the white box

coral lintel Jun 12, 2022, 7:25 PM

#

Can you show how you set up QRCam in your Unity Inspector?

zinc bramble Jun 12, 2022, 7:26 PM

#

coral lintel Jun 12, 2022, 7:32 PM

#

Did you comment that out?

zinc bramble Jun 12, 2022, 7:33 PM

#

yeah. that is from the way that the QR scanner code I used displayed the camera. It didnt work with portrait mode apps so I commented it out. I will delete it later

coral lintel Jun 12, 2022, 7:36 PM

#

Geesh, what a code 😛

#

Anyhow,
background.texture = camTexture;

#

And your background is not the same aspect ratio of your cam

zinc bramble Jun 12, 2022, 7:37 PM

#

i see.

#

is there a way to i guess set the background to part of the camTexture?

coral lintel Jun 12, 2022, 7:38 PM

#

        float ratio = (float)camTexture.width / (float)camTexture.height;
        fit.aspectRatio = ratio;

        float scaleeY = camTexture.videoVerticallyMirrored ? -1f : 1f;
        background.rectTransform.localScale = new Vector3(1f, scaleeY, 1f);

        int orient = -camTexture.videoRotationAngle;
        background.rectTransform.localEulerAngles = new Vector3(0, 0, orient);```
This whole part needs a Debug.Log to see what's what

#

There is some fuckery going on there I don't understand.

#

Maybe set your background to that ratio

zinc bramble Jun 12, 2022, 7:39 PM

#

lol yeah thats all for orientation as far as the tutorial I watched is concerned

coral lintel Jun 12, 2022, 7:40 PM

#

The basics is not that difficult to be honest.
Connect to cam
Get picture from cam
Set picture on canvas

zinc bramble Jun 12, 2022, 7:40 PM

#

yeah its suprisingly simple

#

but making it look right is a real pain

#

you are right it probably is in that section you pointed out tho

coral lintel Jun 12, 2022, 7:41 PM

#

Well can you debug.log those values?

#

Otherwise you need to start over and scrap 80% of this code.

zinc bramble Jun 12, 2022, 7:41 PM

#

maybe. Im not too familiar with that yet

zinc bramble Jun 12, 2022, 7:41 PM

#

coral lintel Otherwise you need to start over and scrap 80% of this code.

yikes

#

what do you mean log? I am not sure what I need to change or what I would be looking for

coral lintel Jun 12, 2022, 7:43 PM

#

        float ratio = (float)camTexture.width / (float)camTexture.height;
        fit.aspectRatio = ratio;

        float scaleeY = camTexture.videoVerticallyMirrored ? -1f : 1f;
        background.rectTransform.localScale = new Vector3(1f, scaleeY, 1f);

        int orient = -camTexture.videoRotationAngle;
        background.rectTransform.localEulerAngles = new Vector3(0, 0, orient);
        Debug.unityLogger.logEnabled = true;
Debug.Log(ratio, scaleeY, orient);

zinc bramble Jun 12, 2022, 7:47 PM

#

this is what gets logged every frame

coral lintel Jun 12, 2022, 7:48 PM

#

Can you make your white box that ratio?

#

You can simply do x=1 z=1.7778

#

or Y

zinc bramble Jun 12, 2022, 7:49 PM

#

is that in the rect transform part of the inspector?

coral lintel Jun 12, 2022, 7:50 PM

#

Still honestly, we have been at it for 50 minutes now. Just copy pasting code from the internet is not a good idea 😛

#

Yeah your Background one

zinc bramble Jun 12, 2022, 7:50 PM

#

coral lintel Still honestly, we have been at it for 50 minutes now. Just copy pasting code fr...

very true. I appriciate your efforts

#

I have been at it much longer than 50 mins

#

either way I think that changing the aspect ration wont do what I want it to. maybe making the image a square will take going back to square one with this camera code.

#

maybe I could use a mask?

#

like use the whole screen but put another image over the raw image that acts as a mask?

coral lintel Jun 12, 2022, 7:55 PM

#

I honestly think its an aspect ratio problem. You can see it in your second and third picture

#

Your mobile phone screen has less width

#

So the Star is smaller on the third screen

zinc bramble Jun 12, 2022, 7:55 PM

#

I am fiddling with this

coral lintel Jun 12, 2022, 7:55 PM

#

But your camera is stretched on that background square

zinc bramble Jun 12, 2022, 7:56 PM

#

I was trying to get away with not using that

#

coral lintel Jun 12, 2022, 7:56 PM

#

Looks good?

zinc bramble Jun 12, 2022, 7:57 PM

#

Lol I'm trying to find a way to make it square for the aesthetic of scanning QR codea

coral lintel Jun 12, 2022, 7:57 PM

#

But this fixed the warp issue

zinc bramble Jun 12, 2022, 7:57 PM

#

Yup.

coral lintel Jun 12, 2022, 7:58 PM

#

Amazing 👍

zinc bramble Jun 12, 2022, 7:58 PM

#

Thanks for your help

#

Back to square one I go

coral lintel Jun 12, 2022, 7:58 PM

#

No problem, was a headache issue 🙂

#

I'm off to bed now, cya around
