Infinity Code Forum → Online Maps Help → Bounding the map to certain areas?
I'm wanting to show a map which is interactable (zoom, pan etc) - but want to limit where the user can go. For instance, setting a minimum and maximum zoom, and not being able to pan past certain bounds, say- a country.
Anyone done anything like this?
Hello.
Example:
http://infinity-code.com/atlas/online-m … ample.html
Awesome thanks for that! Just found those examples now.
Any idea on how I can customise the markers so that when I click on them, I can have information pop up about the location? I’ve tried to use the label thing but it seems quite limited and only really works for hover, or always on rather than tap on/tap off which I’d be going for. Perhaps just spawning some UI at the location of the marker - but I can’t seem to find how to get that.
Also - is it easy to create a few UI buttons in Unity that I can cycle between locations? Eg. pressing button 3 will make the map centre on marker 3.
Thank you!
You need to draw tooltips with uGUI.
Example:

It is very easy:
OnlineMaps.instance.position = someMarker.position;Thanks Alex. Figured that stuff out now.
Only thing I'm having trouble with now is implementing a route animation, being able to press a button to animate a marker moving along a route from marker to marker. I've found the example script "Move Marker On Route Example", but can't seem to figure out how to do this with multiple locations where it can figure out the whole route at once.
Any idea on how I'd be able to customise this so that I'm able to input several locations (or markers) and it can draw a route between them for a seamless animation?
Thanks!
If you are asking about waypoints, use OnlineMapsGoogleDirections.Params.waypoints to find the route using these points.
http://infinity-code.com/doxygen/online … 45a1012e3e
If you mean your own set of points, then just use it instead of searching for a route.
Thanks Alex. Does this work if my points cross over different countries? I want to be able to draw a line between somewhere in England, to America, and then to Australia (which I have markers set to). Then be able to press play and a marker will animate across it.
Is this something that can be done without a route, and just taking the marker location?
Just use your set of locations instead of a route search in «Move Marker On Route Example».
Ah yep. I've figured out how to draw a line from inputting a range of different coordinates (using the Using Drawing API example), but can't seem to figure out how to change the MoveMarkerOnRoute Example to take inputted coordinates instead of the GoogleDirection.
Something like this:

if (progress < 1)
{

// Orient marker
if (orientMarkerOnNextPoint) marker.rotation = 1.25f - OnlineMapsUtils.Angle2D((Vector2)p1, (Vector2)p2) / 360f;

}
}
if (lookToMarker) OnlineMaps.instance.position = marker.position;
OnlineMaps.instance.Redraw();
}
}
}Click on the map to create a waypoint.
Click Start to begin the animation.
That's perfect! Thank you so much - this has helped heaps.
One last thing - any idea on how to disable the location permission when building the app for Android? Since adding the map asset to my project the app now asks for location permissions on install.
Thanks!
This is because Online Maps has an Online Maps Location Service class that uses location permissions.
If you do not use this and have some experience, you can try to remove this class and all dependencies.
Do not forget to backup before you try.
Hi Alex
For me the route gets drawn correctly but the marker is not moving at all. There is no error in the script as well. Is there any prerequisite for this script?
What could I be missing?
Thanks
Hello.
I just checked the work of this script, and it works correctly.
Did you press "Start" button?
I am using this script:
http://infinity-code.com/atlas/online-m … ample.html
It doesn't have code for Start button.
I changed the code a little bit and am now able to make it work.
