Can the kodular set the boundaries of the place, for example, to the boundaties
Hospital 300 meters

With database + Google Maps + programming logic

There is no way to use it. extension?

I want to use only firebase database, kodular, kodular component google maps, Can do that?

use circle component on a map

I did it using the distance inside the circle (I generated an extension using formula to calculate distance between 2 points). So, I created a database to store the type of establishment (gas station, pharmacy â€¦) and the location.

The component map you mentioned is not compatible with google maps? I canâ€™t drag it down.

But, you can use the native Kodular component to calculate the distance using the length of the path to the establishment.

I want to do it in a way that doesnâ€™t require an extension? Can I do ?

What ? I donâ€™t Understand.

Understand how to create the circle and the markers.
Understand the component navigator.
Use your database to make the drawings on the map.

Orâ€¦

Why is it so difficult? Can anyone teach me one step at a time?

2-Understand how to create the circle and the markers.
3-Understand the component navigator.
4-Use your database to make the drawings on the map.

aia blocks ready â€¦( coming soon )

Does anyone have an out-of-bound formula?

I thought about it and it didnâ€™t work at all.

How do I check that it is out of the circle?

I used a formula that calculates the distance between 2 points on the earth and generated an extension.
Option 1 - use it on Kodular blocks
Option 2- use it to generate an extension

Is there an example code for not using an extension? I really canâ€™t

There are different ways of calculating this distance.
You can find it on Google.
Take it and use the Kodular blocks.
I did not use Kodular blocks.
Geodesic Distance (15%) and Haversine

I merged your topics. Donâ€™t double post.
