Adding an instance when mouse is pressed

in Programming Questions • 1 year ago

I'm at the very, very beginning of attempting to make a real-time multiplayer game with Processing and I need to be able to make a new building. I have a class for the building, but how do I make it so that a new instance is made under certain conditions (for example when the mouse is pressed)? My question isn't about the conditions but just about adding an object. I hope that makes sense... Thanks for any help!

Well, add to what?
Let's assume it is adding to an ArrayList, the most common structure to hold a variable number of scene objects.
You make a new instance of a class by using the keyword new.
So the sequence would look something like:

// At the global level (before setup()):
ArrayList<Building> buildings = new ArrayList<Building>();
// Add new instance
Building b = new Building(); // Add parameters if you have some
buildings.add(b);
