|
|
As the director of a small state park, your job is to balance conservation, leisure, and fiscal sustainability. Gameplay is still being added.
|
|
|
|
|
|
This is inspired by Maxis' [Sim series of games](https://en.wikipedia.org/wiki/List_of_Sim_video_games), particularly SimSafari, and Chris Sawyer's [Tycoon games](http://www.chrissawyergames.com/info.htm). Its premise more closely resembles [SimPark](https://en.wikipedia.org/wiki/SimPark), but I never played it except for a demo. (Alternatively, watch [1990's Sim Games. SO GOOD!](https://www.youtube.com/watch?v=APFnM6DqtiA))
|
|
|
|
|
|
I rewrote the core of this game for Procjam 2020, but the majority of the game has been added since.
|
|
|
|
|
|
## Controls ##
|
|
|
|
|
|
Use the arrow keys or move the mouse to the edges to scroll around on the map. The plus and minus keys zoom in and out. 0 toggles pause. F opens the Forest Policy. B opens the budget. N opens News. Escape opens the in-game menu.
|
|
|
|
|
|
## Accessibility ##
|
|
|
|
|
|
To change the font or font size:
|
|
|
1. Open the in-game menu (with Escape)
|
|
|
2. Click Options.
|
|
|
3. Change Font and Size as necessary.
|
|
|
|
|
|
You can also change the scaling, but this should be a last resort if other
|
|
|
options aren't sufficient.
|
|
|
|
|
|
Currently, there are no options for adjusting the difficulty beyond the settings
|
|
|
that appear on the initial selection when you begin a game.
|
|
|
|
|
|
## System Requirements ##
|
|
|
|
|
|
The requirements are pretty modest. It runs pretty well on a 2010 MacBook Pro. Here's my estimated minimum:
|
|
|
|
|
|
* ~2 Ghz Core 2 Duo or equivalent
|
|
|
* 2 GB of memory
|
|
|
* Nvidia GeForce 200 series
|
|
|
|
|
|
If you have a more typical machine with, say, 8 GB of memory, an NVIDIA GeForce GTX, and an i5, you should have no trouble running the game.
|
|
|
|
|
|
## Relationship to past work ##
|
|
|
|
|
|
This game is a total rewrite of the [original version](https://actuallyalys.itch.io/isometric-park-working-title) in C#. I honestly like the original language and library more (Clojure and Quil), but Quil was starting to struggle with the amount of drawing, and I was hitting the limit of my optimization abilities and available information online. (Another drawback: I'm also giving up the browser version, unless people get FNA in the browser working.)

|
|
## Installing and Running ##
|
|
|
|
|
|
* macOS users need to do an [extra step](https://support.apple.com/guide/mac-help/open-a-mac-app-from-an-unidentified-developer-mh40616/11.0/mac/11.0) the first time because the app is unsigned.
|
|
|
* Windows and Linux users should be able to double-click the EXE and run it.
|
|
|
* BSD users can try using [fbsd-fnaify](https://github.com/oshogbo/fbsd-fnaify), although I have yet to confirm it works with Isometric Park. (If you do try it, let me know!)
|
|
|
|
|
|
## Developing ##
|
|
|
|
|
|
To run from the command line, `make run`.
|
|
|
|
|
|
You can build and run the project using VSCode actions.
|
|
|
|
|
|
You can debug the project using the Debug pane in VSCode.

### Updating implot ###
|
|
|
|
|
|
This is a huge pain. The last thing I tried:
|
|
|
|
|
|
1. Download the latest version of ImGui.Net, corresponding to DearImGui 1.86.
|
|
|
2. Removed the ImGui folder: `rm -r ImGui.NET/`
|
|
|
3. Copied `cp -r /tmp/ImGui.NET/src/ImGui.NET .`
|
|
|
|
|
|
### Architecture ###
|
|
|
|
|
|
This game uses an ECS structure, with significant parts of the simulation done in the `Simulation` class and some drawing in the `FNAGame` class. I use Encompass, which calls systems engines. It also adds messages, which last only one frame and are ideal for updates.
|
|
|
|
|
|
I call engines that connect the ECS and non-ECS parts bridge engines. It works reasonably well, although I'm trying to add new code to the ECS rather than to the `Simulation` and `FNAGame` classes.

Right now, the largest parts of the code are `UI/`, `Engines/`, `FNAGame.cs` (which
|
|
|
still contains a lot of drawing code), and `Simulation.cs`.

Watching ThinMatrix's [video devlogs](https://www.youtube.com/watch?v=90CZ7Q17sls&list=PLRIWtICgwaX1gcSZ8qj8Q473tz7PsNmpR) for Equilinox and his subsequent games inspired me to press on. :) Despite some similarities, the design of this game wasn't really inspired by Equilinox. (I've also enjoyed Thoughtquake's [video devlogs](https://www.youtube.com/user/Thoughtquake/videos) and Cliff Harris' Democracy 4 [video devlogs](https://www.youtube.com/user/cliffski2/videos)).
