[AdamHorvath]

This issue has been fixed in the latest version.

@말괄량이연랑

This problem is just make dir.
like this

InputStream is;
ZipInputStream zis;
try
{
String filename;
String FileFullPath;
String filepath;

is = new FileInputStream(path +“/”+ zipname);
zis = new ZipInputStream(new BufferedInputStream(is));
ZipEntry ze;
byte] buffer = new byte[1024];
int count;

while ((ze = zis.getNextEntry()) != null)
{

filename = ze.getName();
FileFullPath = pathDest + filename;
filepath = (FileFullPath).substring(0,FileFullPath.lastIndexOf(File.separator));

Log.debug(" ############### filename: ############ " + filename);
//extract only artoolkit related stuff
if (filename.toLowerCase().contains(“artoolkit”))
{
// Need to create directories if not exists, or
// it will generate an Exception…

File f = new File(filepath);
if(!f.exists())
{
Log.debug(" ############### Not Exist Folder ############ " + filepath);
f.mkdirs();
}

switch plugin UPL Code in

String zipname = obbName;
< In this code >
if (ze.isDirectory())

Is there anything that i can do to fix it?

[AdamHorvath]

Hello,

Thank you for purchasing my plugin!

Please make sure to use the most recent version, I’ve just released today for UE 4.21. It has some fixes for packaging problems on Android. I’ve sent you that version right after your purchase.

It’s not necessary to disable any plugins to package your project anymore.

To create a marker:

1. Create your marker following the link below.
   https://github.com/artoolkitx/artool…torial-markers

The required marker creation tool can be found in the ARToolkit 5.4 package:
https://drive.google.com/open?id=1bY…Zl9eJ9BtPGQGqM

2. Once you have the marker file copy it into:
   \Content\ARToolkit\Data\

(Name it like the other markers: patt.hiro for example where hiro will be the name of your marker)

3. In the editor locate the markers enumaration and add the name of you new marker. (Content/Blueprints)

4. It’s ready to use with the GetMarker node.

First i’m really thankfull for the help that you have given me, that allowed me package to android and add a new marker.
But now i am running into a problem with 2 markers, is there a way to fix this?

Two markers problem

I’ve done this with a new project, and some simples changes to the BP code, you are able to see those changes in the end of the video.
Thank you in advance, i really hope that there a way to make this work!

Hi,
I package Win64 according to your documentation operation.Always fail.Prompt error.

[AdamHorvath]

Hi,

Thank you for reporting this problem. I’ve checked it and turned out it was because of an outdated library file. (libjpeg.lib)
I’ve updated the plugin with a newer version, and it is working now.

The new version name is : 1.13 Revision 1

Please login to you account and update. If you did not create an account just send me your order id and I’ll email you the new link.

Hello,

The AR_Actor_TOUCH blueprint has a plane that receives shadows. It’s a standard static mesh component (Cube). What you experience on the video is the occlusion of the 2 shadow receiver planes.

What you can do is to make the planes smaller to preserve shadows, or you can completely delete them.

Also I would recommend to move / rotate both marker controlled actors using rotation / position nodes, and don’t move the camera.

Hi i was able to fix this issue, now i can do 2 markers detection without a problem and i am very thankfull for your help.

Now i got a new problem, i’ve been looking into your code, but i wasn’t able to modify it in a way to solve the issue that i am having.

We want to be able to detect multiple markers, and when we detect them, we could walk arround the spawned models, the problem here is that the pluggin uses a fixed point to project the marker location, is there a way to feed in the camera location and rotation so we are able to achive this purpose?

https://blueprintue.com/blueprint/o4…noOV9_3boNTgLs

This was my failed attempt to fixe this issue, but it didn’t work.

memcpy(patt_trans, MarkersNFT*->matrix, sizeof(ARdouble) * 3 * 4);
MarkersNFT*->position = FVector(patt_trans[0][3], patt_trans[1][3], -patt_trans[2][3]);

This was my road block when i was searching to try and get a dynamic base location to work.

PS:
The work arround that i’ve made… It would be nice if you could update the pluggin to recieve a dynamic origin instead of this static one.

@SatyamYadav

Hi Developer , we are using your plugin to create some applications for android ,
and we are facing some issues with it , In Editor everything works fine but when we package it for android , we are not able to see any camera output , all we can see is a white screen (which we guess is the plane which is infront of the camera ) , We are working on a demo project from the official website and the plugin we are using is a commercial one .
Please help us
ThankYou .

Hi I’m having the same problem than SatyamYadav, and i’m working with the very last version of the plugin (Plugin project example) and Unreal 4.21. Besides, I’m trying to the app to a motorola G6 phone with Android 8.0.

Does anyone have a solution? (I attach the phone log file)

[AdamHorvath]

Hello,

You are trying to run the DEMO version on android, but it only works on windows and mac.
For mobile devices you need one of the paid versions of the plugin.
