Hello, I Am Making a java Game, As in i am going to accomplish this because it is a necessary life goal.
I am Making a Top Down zelda link to the past clone, but i want to modernize the game engine so for all intensive purposes I am making a top-down "Retro" game engine in pure java with Modernized aspect,. This would include a seamless open-world Generated as a fractal with a horizontal wrap (Walking to the left and going "Around the world") not divided modules, And maze generation for Sub locations on the larger world map,. being as the game would be tile based my assumption is that I can "Cookie cut" a large stock of unique locations with modifiers onto the world map, by simply pasting a modified object that corresponds to a dungeon entrance. Or to "Cookie cut" Various Buildings onto the map with Included NPC characters.
I think these would be the more/most complex features I Would need to have a detailed understanding on how/what is required to be used to accomplish theses things, I am A Vary novice level programmer and am eventually going to accomplish this but need to clearly understand what I need to learn beyond the basics, I would be eternally greatfull for some assistance and that is not to say to have some one code for me but to have a bit of conversation as to how and what I am to do to accomplish this goal i have had for a very long time.

Sorry I Was not Clear,- how Would I Make A seamless top down world, That is generated from a fractal pattern and then implemented into a wrapping map for a 2d top down character, for a procedural generated experience, what Would I need to know.
