QUESTION
I'm developing a simple navigator with mapbox API for Android.
I'm creating some routes using https://docs.mapbox.com/playground/directions/ playground and i would like to use the generated JSON to generate a DirectionsRoute object.
So i call DirectionsRoute.fromJson() but when i do it, the application crashes with this error:

Answered 2021-Jun-15 at 08:12The response from the mapbox API is not DirectionsRoute. It is DirectionsResponse, a structure that looks like this:
QUESTION
I'm working on a 2D game in Unity and am using the A* Pathfinding Package from Aron Granberg.
Everything appears to be working fine. AIPaths are being generated and AI Agents are navigating from point to point and avoiding obstacles as expected. It's fine except for one thing.
The position.z of the AI Agent is incorrect.
The spawn origin of the AI Agent has a z of 0, and the target point has a z of 0, yet the AI Agent's z fluctuates between -9 and -1 as it traverses the path. The path itself appears to have a z position of 0 at each waypoint.
I haven't modified the code in the package at all and just followed the documentation when setting it up for 2D.
Any ideas what could be causing this?
NOTE: I haven't included a screenshot of it, but the prefab that is being spawned in as the AI Agent has a transform position of (0,0,0).
The A-star pathfinder object:
The AI Agent object (note that the Z pos is not 0):
The spawn point object that sets the spawn for the AI agent:
The destination target object that the AI Agent is heading to:
...ANSWER
Answered 2021-Jun-14 at 02:09In case anyone else runs into this problem.
The fix was to add a Rigidbody2D to my AI Agent and set the gravity scale to 0.
Even though my game doesn't use Unity's physics system for movement and the Astar package can move AI agents by transform, for some reason it requires a Rigidbody to keep the Z position at 0.
I'm still not really sure why this solves the problem because, when I was debugging the third-party Astar code, it always returned nextPosition values with a Z position of 0 yet the actual position that the AI Agent was updated to had varying Z positions...
If you have more info, leave a comment and I'll add it to the answer.
QUESTION
I'm using the following to animate the route being drawn in React Leaflet, which works nicely. However I'd like to use onAnimationEnd for the CSS. I can't figure out where to find the element and attach the eventListener.
ANSWER
Answered 2021-Jun-11 at 21:08You've set this up very nicely. Your RoutingMachine component is well written, and you already have your ref to it. Great. Let's examine RoutingMachineRef in the console:
As you can see, if you dig through, the svg path component can be found at RoutingMachineRef.current._line._layers[some_layer_id]._path. But watch out because sometimes leaflet routing machine will draw multiple layers (separate svg layers for rounded line caps, etc). You can actually access these dom elements directly through the RoutingMachineRef.
I'm not sure which one of these gets the .animate css class in your code, but you can probably just add your event listener to each of these. I imagine only one of them is going to actually animate (potentially a problematic assumption there), so the event listener will only fire once, when the one that has the .animate class stops animating:
QUESTION
I am using Here SDK version 4.7.4 for the Android navigation app. So, We calculate the route using our web portal and want to use the same route that we calculated(using the web portal by calling here REST API) in the Android Navigation app.
I have searched online for this and unfortunately did not find anything worthful.
Currently, In the Here map Navigation example, It calculates the route using the below lines of code:
...ANSWER
Answered 2021-Jun-07 at 20:53You cannot convert the Route object that you have received from the REST API call to a Java or Kotlin object that the HERE SDK can understand - as JavaScript/JSON vs. Java / Kotlin are not compatible, and most importantly, the Route object cannot be generated on app side from scratch as no constructor is publicly accessible.
You can only try to create the route again with the same parameters that you have used on your web portal. The results may differ, as it is a new calculation and time and traffic situation may change the route.
A better solution may be to talk to the HERE support team and ask them to allow creating routes from a given RouteHandle. The route handle uniquely identifies a route and it is just a String representation of a route. The REST API can generate the handle and the HERE SDK can then consume it, in theory ...
QUESTION
I have the following problem:
I built an app that has 6 buttons and each of these buttons is assigned a CL region. I have a GPS track file that provides the app with locations and simulates a walk.
Now buttons should turn yellow when the region assigned to them is reached. It works so far, but the problem is that I don't know where to ask whether or not to reach the Region of Button. I tried .onAppear () {if ...}, but that is only triggered once and I need something that monitors the If statement all the time.
Is there anything?
Thanks in advance
here my code:

Answered 2021-Jun-04 at 15:45You can use onChange to monitor the status of RegionIndex. It might look like this (replacing your onAppear):
QUESTION
I have a Blazor site, I am using an HTML template that has CSS and JS for styling.
I have imported the assets into the wwwroot, and I have made a reference to them in the _Host.cshtml file; The styling and certain elements seem to be working... However I've noticed the animations and other portions of the javascript are not working as intended...
For example, I have an accordion, and it doesn't expand or close.
I made the same page in an HTML format and put that in the wwwroot... When I run the code and navigate to that page, it seems to be working just fine. But on my razor page, it is not...
This is it on the .razor component
This is it on the .html file I made in the wwwroot
_Host.cshtml
...ANSWER
Answered 2021-Feb-10 at 18:19Good afternoon,
From my experience calling Javascript in a Blazor Component requires use of the IJS runtime. Here is the Microsoft Blazor Documentation for this issue:
https://docs.microsoft.com/en-us/aspnet/core/blazor/call-javascript-from-dotnet?view=aspnetcore-5.0
Essentially you use the IJS runtime to call specific methods from your custom JS documents.

I've created a TileMap. My enemy is a simple cylinder with an "EnemyMover.cs" script attached and is in the scene (hierarchy) before play is pressed. (Not instantiated during runtime)
On a separate object, I have a "TargetLocator" script which attempts to utilize GetComponent to find the cylinder script component when instantiated by click on a tile on the map during runtime.
...ANSWER
Answered 2021-May-30 at 23:26Rather than transform , which is the real-world location of a object, try calling a method that is in that script.

Following the offical reference for Higher Level Component Factory to update props for a Control Component
The core APIs export other high-level component factories that can be used in a similar way.
I've mimicked the example - but I get a syntax error for the following:
...ANSWER
Answered 2021-May-24 at 14:37You will notice that in the docs, createcontrolcomponent lists only one argument, which is a function to create the instance. You are expecting it to behave like createlayercomponent, which takes two arguments. In createlayercomponent, the second argument is a function to update the layer component when the props change. However, createcontrolcomponent offers no such functionality. react-leaflet is assuming, much like vanilla leaflet, that once your control is added to the map, you won't need to alter it directly.
This gets a bit confusing in terms of leaflet-routing-machine, because you don't need to change the instance of the control, but rather you need to call a method on it which affects the map presentation.
IMO, the best way to go is to use a state variable to keep track of whether or not your waypoints have changed, and use a ref to access the underlying leaflet instance of the routing machine, and call setWayPoints on that:
