EngoEngine has a city builder tutorial. It is incomplete and hasn't been updated since Feb 2021. Trying to finish the incomplete(and most difficult) parts.
Beginning can be found here https://github.com/EngoEngine/TrafficManager/tree/01-hello-world
I have changed multiple parts for better code re-usability. I have added an updated UI, new money system, created roads to be built between cities, new message systems, changed mouse functions, and more.
I most recently added a path seeking system for roads built. Roads connecting multiple towns will upgrade to cities, to metros, ect.
Currently every road built not at the front of a current path creates new paths. For example Image the following grid(R = road, C = city, NR = new road):
_, 1, 2, 3, 4, 5, 6
1, r, r, --, --, --, --
2, --, r, nr, --, --,--
3, r, r, --, --, --, --
4, --, r, --, --, --, --
before the new road at Row:3, Col: 2 there are two paths:
[1][1] -> [1][2] -> [2][2] -> [3][2] -> [4][2] &&
[1][1] -> [1][2] -> [2][2] -> [3][2] -> [3][1]
After the new road at [3][2], there is obviously a new path from [1][1] -> -> -> [2][3].
But is there a path from:
[3][1] -> -> -> [2][3]?
What about:
[4][2] -> -> -> [2][3]?
All of these paths must be considered if a new city later appears adjacent to one of these roads.
The Solution: All paths must begin at a city.
To solve this I am changing it so roads can only be built adjacent to a city, or adjacent to an already present path. This will significantly reduce the number of paths that must be considered.
Next I will be adding audio, traffic management, and traffic visuals.
To run game, clone the repository, and in terminal run:
$go mod tidy
$go mod run .
This image shows a path between two cities. A path connecting to a city will receive a teal highlight. A path that breaks off from that original path will have a red/orange outline. Roads can be built by clicking adjacent to a city or road while you have >= $50. Will later add different colors for incomplete paths, wider paths, ect.
