Launching script without attaching to game object

Can scripts be launched without being attached to a game object? or should there always be an empty object
present?

 

Hi @DoomDude99,

Methods marked [RuntimeInitializeOnLoadMethod] get invoked after game is started. These can be in any script folder, there's nothing required to reference them in the scene, like a Monobehaviour class (afaik.)
See docs: https://docs.unity3d.com/ScriptReference/RuntimeInitializeOnLoadMethodAttribute.html

And you can run instances of classes that are not inherited from Monobehaviour, just create them by using new MyClassName and so on? But you need some Monobehaviour script in your scene where you do that.

 

Thx

 

This is great for starting a script after the game starts but is there a way to listen for the game ending in order to carry out clean-up? It seems the scripts destructor is not always called right as the game end and sometimes instead as the game mode is re-entered (in the editor anyway).
