Array from another plugin

Is it possible to get the array from another plugin or set the array values from another plugin?

Yes.

@hoyinm14mc sorry if I ask but have you a code for that?

Do a getter.

PHP:

public function getArray()
{
return $this->array;
}

And how can I set the value of the array?

Handle it like a normal array.

Okay

OMG why would you do that???

Why don't simply get the class property directly?
$otherPluginObject->publicArray

Why not?
