I've just started my first Unity experience by moving a match-3 based game to Unity, and I want to be able to attach data to each available tile type specifying how likely that tile is to be dropped onto the board (and be able to override that value for each level). There are a few match-3 tutorials floating around, but besides a tendency to not explain how to make things happen in Unity, I haven't found any leveraging the Tilemap, which seems a shame since it looks like it provides a fair bit of necessary functionality. The only problem is, I don't see anywhere to attach data or a script to a base Tile, so I've been looking into whether going the Scriptable Tile / custom editor route would get me what I need; but then I run into the lack of instructions on how to get basic functionality on the custom editor (the ability to specify the underlying sprite seems rather fundamental, but I'm not finding anything).
Anyway, is the Scriptable Tile interface my best bet to get level-specific data attached to individual tiles, or should I be looking for a different way to get this data on there? Or should I just ditch the Tilemap and the functionality it does include out of the box altogether like all the tutorials seem to be doing?

My university colleagues and I are trying to develop a Virtual Reality project for university where we use an Oculus headset and create a scene with a mouse where you can select and click and drag different objects in the scene. You are supposed to be stationary and move one of the controllers as if it was a mouse. However, we want to modify the behaviour of the controller to better fit the 3D environment. When an object is not selected, we want to interpolate the depth of the cursor according to the interpolation of the nearest objects. There is a paper that we were shown in class that we are supposed to drag inspiration from, and it achieved this kind of behaviour of the cursor with a normal mouse but I can't seem to find any information on how they did it. Our final goal would be to compare both ways of managing the scene and assess which one is better. We are using Unity with VRTK as suggested by our professor, but we and can't really seem to be able to access the mouse's file on how it moves or its behaviour, and we are kind of lost on where to go. Could someone help with this?
Here is the paper where they talk about it:
https://dl.acm.org/doi/pdf/10.1145/3491102.3501884
We so far have tried creating a simple scene and adding objects with different behaviours as well as a controller instance, but we seem to only be able to modify the events of the mouse and not its specific behaviour.
Kind regards and thanks
Feel free to close this question if it is deemed too subjective. I realize that it might very well be, as it may focus heavily on best practices, which, if not an industry standard, may be subjective.
The Problem & Idea:
I'm using the tilemap system in unity (2D), and its been working great, but I have a few concerns regarding my particular usage. What I'd like to have is multiple "battle maps" that will get instantiated when the battle scene is switched to. My current idea is to just make each type of battle map a prefab (prefab on the grid, since the tilemaps are just layers), and then instantiate the grid when the scene loads in.
Is this best practice or is there any better way? Does having 10 maps vs 200 maps make a difference?
Other Things I've Considered:
Would it be a better idea to make one huge tilemap with all of the battle maps drawn a distance away from each other and just restrict the camera to moving only within the "current" battle map? The absolute max size I could see a map being is, let's say 30x20 tops, probably closer to half that though.
An earlier idea was to use small pixel map images to render the maps in. This was before I found out about Unity's tilemap system, which, admittedly, I'd rather use because it is so much simpler to visualize, and less work to develop.
The Scenario:
For simplicity's sake, let us assume the game has 2 scenes, the main menu, and a battle scene. Basically, the idea is to enter the battle scene and have a random battle map to be spawned out of what's available. The character(s) get placed, and any additionals also get placed, say, items, or what have you.
Is what I proposed above best practice? And should I consider any other other two systems I've also described? Or is there something I'm not thinking of that would be even better?
I don't believe that any of the above ways wouldn't work, I'm just curious if any of them is the best way to go about doing this.
Your consideration to have all of your battle maps drawn on a single tilemap and restricting the camera to only the region of the current map is an instant red-flag.
In my experience with unity, if I want to have a large level drawn on a grid I will have to break it up into chunks (each chunk is a separate tilemap) for performance reasons in the editor and in the game, so I would not recommend doing that.
If your goal is fast load times, then instancing a prefab as you suggested is not a terrible idea as long as the respective tilemap is fairly small (less than 10000 tiles), otherwise you would almost difinitely notice the map getting loaded in. If you are trying to load large tilemaps seemlessly, it may help to load the tilemap asynchronously before the actual switch occurs.
I would keep only the current map and next map loaded in the scene to ensure a seamless transition and optimal resource usage. Unity's tilemaps are not light.
Currently, I know that Vuforia can track objects that are scanned in the targets database. This means that if I wanted to recognize many objects, I have to scan each of them and upload them into the database.
Here’s what I want to create. I want to create an app using Unity that can recognize and track simple shapes (such as a rectangular box or a spherical ball) disregarding the size. For example, the app should be able to recognize a small Kleenex box as well as a big shipping box.
Is it possible to recognize these shapes with minimal object targets (e.g. recognize all rectangular objects with one object target)? If so, how can I set up vuforia to do so? I understand that this question may be confusing to understand, and I will do my best to elaborate more clearly. Thanks so much!
I'm working on a project for an exhibition where an AR scene is supposed to be layered on top of a 3D printed object. Visitors will be given a device with the application pre-installed. Various objects should be seen around / on top of the exhibit, so the precision of tracking is quite important.
We're using Unity to render the scene, this is not something that can be changed as we're already well into development. However, we're somewhat flexible on the technology we use to recognize the 3D object to position the AR camera.
So far we've been using Vuforia. The 3D target feature didn't scan our object very well, so we're resorting to printing 2D markers and placing them on the table that the exhibit sits on. The tracking is precise enough, the downside is that the scene disappears whenever the marker is lost, e.g. when the user tries to get a closer look at something.
Now we've recently gotten our hands on a Lenovo Phab 2 pro and are trying to figure out if Tango can improve on this solution. If I understand correctly, the advantage of Tango is that we can use its internal sensors and motion tracking to estimate its trajectory, so even when the marker is lost it will continue to render the scene very accurately, and then do some drift correction once the marker is reacquired. Unfortunately, I can't find any tutorials on how to localize the marker in the first place.
Has anyone used Tango for 3D marker tracking before? I had a look at the Area Learning example included in the Unity plugin, by letting it scan our exhibit and table in a mostly featureless room. It does recognize the object in the correct orientation even when it is moved to a different location, however the scene it always off by a few centimeters, which is not precise enough for our purposes. There is also a 2D marker detection API for Tango, but it looks like it only works with QR codes or AR tags (like this one), not arbitrary images like Vuforia.
Is what we're trying to achieve possible with Tango? Thanks in advance for any suggestions.
Option A) Sticking with Vuforia.
As Hristo points out, Your marker loss problem should be fixable with Extended Tracking. This sounds definitely worth testing.
Option B) Tango
Tango doesn't natively support other markers than the ARTags and QRCodes.
It also doesn't support the Area Learnt scene moving (much). If your 3DPrinted objects stayed stationary you could scan an ADF and should have good quality tracking. If all the objects stay still you should have a little but not too much drift.
However, if you are moving those 3D Printed objects, it will definitely throw that tracking off. So moving objects shouldn't be part of the scanned scene.
You could make an ADF Scan without the 3D objects present to track the users position, and then track the 3D printed objects with ARMarkers using Tangos ARMarker detection. (unsure - is that what you tried already?) . If that approach doesn't work, I think your only Tango option is to add more features/lighting etc.. to the space to make the tracking more solid.
Overall, Natural Feature tracking by Vuforia (or Marker tracking for robustness) sounds more suited to what I think your project is doing, as users will mostly be looking at the ARTag/NFT objects. However, if it's robustness is not up to scratch, Tango could provide a similar solution.
I'm creating mobile racing(in space) game and it's first person so there is always big cockpit occluding big part of scene. Can I somehow use the fact that I know it to optimize rendering? I have heard that draw call order can be changed, but I don't know how exactly it would work.
The thing you are looking for is called "Occlusion Culling". Here is a guide from the Unity manual explaining how it works and how to set it up.
NOTE: This only culls static objects, if your cockpit moves with the player objects covered by the cockpit will not be culled by using this method. If you want to do occlusion culling with dynamic objects you need to get a 3rd party asset from the store like InstantOC, it even has a "Mobile Aircraft Controls" prefab (Note, I have never used InstantOC but I have heard good things about it).
