I am using the map to track pets. Each marker that is placed down is a pet’s location and when I get an updated location of their whereabouts, I have to delete all the markers to update one pets location. I’ve temporarily found one way around this without having to delete specific blocks. I have to set the location variable for each pet and then update each pet’s location every time there is a change. It’s a lot of unnecessary blocks and I also can only have as many pets as there are variables that I set up beforehand. It would be nice to have the option to track as many pets as I want without having to set a variable for each pet. One variable should be enough.
Care to share how you update a single marker ?
If you’re using many variables to store the same type of information, then you really should be using a list instead and storing that list (which is dynamic in size) in a single variable.
I’ve thought about that, I’m just not sure how to go about doing that. I’ve also thought about using an object in a list for the Coordinates, but I’m not sure how to go about updating objects that are nested in a list or objects that are assigned to a pet name in a list.
Right now this is how I have everything set up:
- The phone receives data from the receiver which receives its from the pets harness.
- I use a space as the delimiter to get information at certain spots in the data string.
- Harness ID
- Lattitude
- Longitude
- Harness battery life
- Satellites in view
- Horizontal dilution of precision (Hdop)
- Power mode (live tracking, power saving mode, extreme psm)
- Light status (bool if the light is on or off)
- Color choice (color of the light if it is on)
- Signal Strength of the harness to the receiver (RSSI)
- The data stored in a list called temp list
- Then rewritten when the phone gets an update from the receiver.
The values I would like to store are the Coords for each pet that way if there is a loss in power or disconnection from the receiver it will have the pets last location. I just need to update the rest of the data but not store it. Each pet will have their own unique Harness ID, and that’s how I tell them apart.
I guess my thought process was if that data coming into the phone had a different harness ID, then it would just delete the marker with that harness ID. But I guess long term for what I’m wanting to do, it would be better to store all that data in a list for each pet somehow.
If you more than one or two categories of data (you have ten), then you should be using a Data Source, not a list and not a bunch of individual variables.
I didn’t even think about using a database. Thanks for that suggestion, I’ll look into using an internal one.
