Comment on Unity, Vuforia & ZXing – Barcode scanning in AR games by Michael

Take a look at the implementation of the class InvertedLuminanceSource from ZXing.Net. Since the current version 0.11 it supports decoding of inverted barcodes like your QR code.

me again I now realized that it only scans qr with black dots and white bg… and I fail miserably to edit the code to apply a negative filter to the image because my qr graphism are more like the opposite. I am already very close, I am trying to modify the RGBLuminanceSource() luminance data but with no luck…I am not too sure what to apply mathematically to make it work.

Would you happen to know how to do that so that this kind of qr can be scanned?

The annoying thing is that the same qr but negative ( using photoshop), will scan just fine…

Thanks

Hi, we’re playing cat and mouse indeed I was able to solve the problem, by simply not relying on the Loom.QueueOnMainThread((). It simply didn’t work for me for some very odd reasons. so what I do is simply save the result in VuforiaScanner class and then check on a regular MonoBehaviour.update()

thanks

Nearest point on the path is a tricky one – I’ll try and dig out the code for it.

Sorry just saw this (the site is supposed to be putting comments in my forum, so I’ve no idea why its ended up here – must have been a WordPress upgrade issue).

If you haven’t managed to fix this – it would be down to using Loom.QueueOnMainThread before comparing the objects or comparing something to null.

Comment on Unity curved path following with easing at constant speed by NeedNap

I have a sphere rigidbody that responds to AddForce method. In my scene I have a terrain with a road and an spline path used to get the “way points” and the camera track. When the sphere stops, I need to set his position to the nearest point on the spline path.
I used your library but I can’t to do that .

My code is:

…

public Transform[] controlPath;
public Transform lookAtPosition;
public Transform sphere;

private float t = 0;
private bool _moveToPoint = false;

void LateUpdate()
{
if (!_moveToPoint)
return;

lookAtPosition.position = Spline.MoveOnPath(controlPath, lookAtPosition.position, ref t, 0.5f);
_moveToPoint = false;
}

public void setMoveToPoint(bool value)
{
lookAtPosition.position = sphere.position;
_moveToPoint = value;
}
…

In this code I used another gameobject (lookAtPosition) because I need to set its position some steps forward on the path then set the main camera lookAtTarget method to that.

I hope you can help me!
Thank you in advice for your help

Hello,

Your code works fine, but is it possible to add a path dynamically during movement?
