Get variable from another plugin

How i can get $variable from an plugin (plugin 1) to another plugin (plugin 2)??

Variables are local. You can't even get it from your own plugin if the function has ended.

You can save the variables to fields, and create getters for them. Then call the getter function from another plugin using Server->getPluginManager()->getPlugin()

well?

PHP:

Server->getPluginManager()->getPlugin("PluginName")

I think this should work.

PHP:

$this->getServer()->getPluginManager()->getPlugin("PluginName");

Only in the case that you are in a PluginBase's context.

Oh I am still learning the API. I just need a good reference for the API...
