Now planes that drop supplies appear at a certain frequency, which can be configured in the world settings.
This mechanic can be made much more interesting in the game.
One option,
and the simplest, is to add a random value in the settings, like you did with the Blood Moon Horde, so that you can set the random frequency of the supply plane spawning.
The second option
is much more interesting.
I don't know what plans the developers have for these radio stations, but I want to suggest such an option for their use.
The location can meet working and broken radio stations (working versions will have flashing lights and they will hiss and snippets of some conversations)
Broken radio stations can simply be dismantled for resources, as it is now.
It will be possible to interact with working radio stations (by pressing the E button).
When the radio is activated, a military voice will sound from it, which will inform you that my request to send supplies has been accepted.
After that, the radio will sparkle, smoke will come out of it (as is the case with quest generators), and then the radio will turn off and become inoperative.
Activating the radio will start a script that will call for a supply plane, but only the next day (it takes some time to send a supply plane).
The next day, a regular plane will fly in and drop supplies.
When the bandits appear in the game, at the supply landing place, when approaching the box at a distance of 100 blocks, bandits should spawn next to it (who also saw the plane and decided to take the supplies for themselves). To pick up supplies, you have to fight the bandits.
As long as there are no bandits in the game, zombies can play their role.
Supplies should not come easily to the player.
And in this case, the contents of the supply box can already be made better than it is now.
If you like this idea, write about it in the answers so that the developers see this idea.
