How do you properly connect the QR code images to the Empty Game Objects in QRCodeRecenterTargets so the QR reader associates the code to the gameobjects. You mention at 27:37 that you will copy it in, but I'm a little lost on where you are putting them and connecting them to the empty GO's.

[@firedragongamestudio]

It's not about the images, it's about the values of the QR codes. The names I put into SetNavigationTarget (15:00) is checked for the scanned QR code value. And the final connection is made at 23:00, where I connect the values to the empty GOs.

Hey really amazing video!! I had a few doubts hoping you could help me out. I wanted to ask how are we linking the qr codes images to recenter targets . Like how after scanning the code are we getting recentered because in my system I am not getting recentered and hence I am not able to understand whether the code is getting scanned or not.

[@firedragongamestudio]

It's not about the images of the QR codes. It's about the content. The QR code reader (ZXing) detects the information within the codes and matches them with the recentering points. So any mistakes in writing the names will result in "no match" and therefore not recenter.

Hi, it's basically like building a 3D world, where slopes are connected to the plains and work like stairs for the navmesh. In my experience the camera tracking often gets lost, when walking stairs, so it would make sense to "recenter" after stairs and to work with arrows or smth similar instead of the path calculation. There was someone who solved it via OffMesh Links so there is a bunch of possible solutions 😃

Hey this is an awesome and very helpful video series. Especially for begginers! I do have a single issue in my implementation and I was wondering if you could let me know where you think my issue stems from, As I see it the navmesh path doesnt get calculated properly. In person when I move, the navigation line seems to get offset. In addition, when I scan a QR code and my indicator gets teleported to the correct location, the path gets offset (although the path shape is accurate) from the indicator. What do you think is wrong?

Maybe your starting position is not accurate. You'll have to start exactly where you have the world origin.

[@glnhlphlvn]

How can I solve this issue? I couldn't find a solution. In my app, I have products on market shelves. In this case, the market shelves should be marked as 'not walkable' for the correct pathfinding. However, since the products should be placed directly on the shelves, they need to be in a 'walkable' area as their destination points, so that the pathfinding can detect the starting and ending points of the route. I hope I was able to explain it clearly. Thank you for these amazing videos!

[@glnhlphlvn]

chat GPt said that :To solve this issue, you can try the following approach: Divide the market shelves into two separate layers: one for the physical representation of the shelves and another for the walkable areas. Mark the physical representation of the shelves as "not walkable" to ensure the correct pathfinding. Place the products on the walkable areas, which can be positioned just above or adjacent to the shelves. This will allow the pathfinding algorithm to recognize them as valid destination points. Adjust the collision detection or physics settings to ensure that the products can be placed precisely on the walkable areas. Modify your pathfinding algorithm to account for these walkable areas as valid destinations. It should be able to detect both the starting and ending points of the route accurately. Test your implementation thoroughly to ensure that the pathfinding works correctly and the products can be placed and reached without any issues. By separating the visual representation of the shelves from the walkable areas, you can achieve the desired behavior of having the shelves marked as "not walkable" for pathfinding purposes while still allowing the products to be placed in walkable areas as their destinations.

[@firedragongamestudio]

The ChatGPT solution already seems good. A way easier solution would be to just define "walking points" for each product at the floor and exclude the products themselves from the path calculation.

Hi, well that's a very complex topic. The mini map is just for a simpler overview here. When using it for more complex interaction there will be some limitations, esp. when the smartphone camera loses tracking.

Hello, could you please help us resolve the below issues that we're facing while we're building this project at our end: 1. LINE RENDERER is not visible 2. Cannot see the dynamic INT option (Part 2) 3. Facing scaling issues i.e the pointer is moving in some other direction and with random speed.

[@firedragongamestudio]

Commenting multiple videos with the same comment, doesn't really motivate me answering... But nevertheless, I'll try my best to help you. 1. Answered multiple times in the comments and in the video itself. Check with InEditor debugging (introduced in the video) if a path is generated by NavMesh. 2. Check if the script is placed correctly on the Indicator, check the project on Github for further info. 3. The only thing that comes to my mind here, is that your camera tracking is not working correctly or your orientation of the minimap/indicator is wrong.

How do i set the line renderer height? Like have the line in ground instead of floating in air

[@firedragongamestudio]

Easiest way is to move the geometry down before building. Please note that the world origin will still be 0,0,0 when starting the app, so you'll have to be careful to not break the path calculation. I've done it in the past via a separate recenter point at the start point, where the QR code was at a predefined heigth (like 80cm) , the room geo floor was at -0.8m and after app start I simply recentered.
