Load Maps

Hey. I have a problem. I recently created a theme with how to create an ItemFrame with a given picture. Now there is another problem. Yes, I created a map, but after restarting it turns into a void. How to do it? Do I need to download from a folder? Whereas?

I used a utility from Zombie_Striker

After restarting the server or...

 

you have to reset the image after a reload/start

 

How?

 

someting like this:

get id

Code:java

MapView mapView = Bukkit.createMap(Bukkit.getWorld("world"));
short mapID = mapView.getId();

reload map after shutdown/reload

Code:java

MapView view = Bukkit.getMap(/*your map ID*/);
for (MapRenderer m : view.getRenderers()) {
    view.removeRenderer(m);
}
view.addRenderer(/*your custom renderer*/);

this was written for Bukkit 1.12, and maybe need some updating... ill try to look if it was updated later this day.
