Top down real-time strategy.

Hello I’m just starting out in Unity with no previous experience of making games. Mod making yes, mostly database editing and some scripting, but not building from scratch. Also I’m doing this on my free time not professionally but have a clear conceptual view of what I want to create. I’ll outline the basic concept and then get to the questions I have.

  • Top-down 2d interface.
  • Real-time game clock.
  • Large map intended to be a representation of a real-world area.
  • Game objects on-map placed with pixel-accuracy. These objects could be 3d I suppose, but I’m not going to look at that at all until understanding how to use the 2d features.

So I’ve spent time looking through some tutorials there are a lot of them which is great. Despite there being plenty dealing with 2d game creation can’t find what I’m looking for. It seems nobody is building the type of game I have in mind.

  • The first issue is creating the map. I have a bitmap of ~2500x3500 that I want to use as a ground texture. Do I need to make tiles of the map or can it be placed as-is? Use a different file format?

  • The database and scripting will be quite extensive, looking at creating 1000+ locations of various categories and properties, but how do I create a pixel-grid as a reference for all locations? Is it already in the engine, then how do you make use of it?

Those are really the two main questions I have to get going. I understand that these questions are as basic as it gets, but if someone could point me in the right direction here so that I can start poking around and learn more as I go that would make all the difference for me. The tutorials are great and well done, but so far I’ve not encountered one that descibes what I’m trying to achieve.

Anything that would help me out here is much appreciated.

The 2D tools in Unity are still not very mature yet so they can actually be more difficult to use than 3D, but please don’t put off 3D just because you want to learn all of 2D first. Game making in Unity isn’t like an RPG where you have to master one skill before you go on to another (learning some things can be easier if you know others though). Almost everything pertaining to 3D game logic applies to 2D and the things that don’t are stuff like changing a type (Collision2D vs Collision as an example) or dealing with 2 vs 3 axis in the game space. That being said here are some tutorials to look into for this:

Just for reference on the level of coding and whatnot you’re looking at here (https://theliquidfire.wordpress.com/category/projects/tactics-rpg/) is a tutorial based on Final Fantasy Tactics systems for Unity. The map system, character classes, and AI are probably going to be the most helpful.

Edit:
Make a game design document of some sort for a project this size because there is a good chance you will forget stuff or give up if you don’t.
