## Introduction
**Welcome to Botanim!**
In Botanim you play the role of botanist and your goal is to cultivate flowers in an open landscape.
Flowers can only grow (well) in certain climates based on two properties: humidity and temperature. Watch out for existing vegetation to get an idea how humid the land is and check the appearance of the tile to see how hot it is. When well placed your planted flower will spread soon but an odd choice might kill your flower almost instantly. So choose carefully. When the flower spread significantly you can harvest flowers again to collect more money.
**Controls:**
- H: Selects harvest tool
- R: Selects research
- Spacebar: pauses game
- 1: runs game at normal speed
- 2: runs game extra fast
- Mouse wheel or plus/minus: zooms landscape
- W, A, S, D keys or CTRL + left mouse button or middle mouse button: pans landscape
** On screen **
On the left side of the playing screen you'll find several buttons:
- Settings: disabled.
- Save: saves the game instantly, only single slot.
- Load: loads previously saved game instantly.
- New: starts a new game with a different terrain.
- Information: shows the intro/information screen (again, also accessible with the Escape key).
Have fun playing!
## Additional Rules
### Implementation
**genre rule #130**
This rule is the most obvious. The goal of the game is to grow flowers so given enough time and a bit of luck your screen will be full of flowers.
**artistical rule #60**
The least obvious and not finished within the time contraint: when researching you'll have to dial a phone number like you used to do with an old rotary dial (works by repeating the number on the keyboard an exact number of times).
**technical rule #10**
The terrain is based on (several: humidity, temperature, placement of props, variants of props) perlin noise functions.
**technical rule #68**
The description of the flowers will scroll below the icon of the "buy flower" buttons when hovered.

## Building
Prerequisites:
- [SDL 2.0](https://www.libsdl.org/) (SDL2, SDL2_image, SDL2_ttf and SDL2_gfx development libraries are required; for [more information](https://github.com/veandco/go-sdl2)).
- [SDL 2.0](https://www.libsdl.org/) (SDL2, SDL2_image, SDL2_ttf and SDL2_gfx development libraries are required).
- [Go](https://golang.org/dl/) 1.12 or later.
- GCC or a compatible compiler.
- [Git](https://git-scm.com/download).
- GCC.
- Git.
With all prequisites installed you can run:
```
go get -u opslag.de/schobers/tins2020/cmd/tins2020
```
This will create the binary `$HOME/go/bin/tins2020`. Additionally you can embed the resources and build a static release with the following commands (this assumes `$HOME/go/bin` is available in the `PATH`):
```
go generate opslag.de/schobers/tins2020/cmd/tins2020
go install opslag.de/schobers/tins2020/cmd/tins2020 -tags static -ldflags "-s -w"
```
If you want to use the Allegro backend you can add the build tag `allegro` to the `go install` command. E.g.:
```
go install opslag.de/schobers/tins2020/cmd/tins2020 -tags static,allegro -ldflags "-s -w"
```
In this case the SDL 2.0 prerequisite is replaced by the Allegro 5.2 (development libraries must be available for your C compiler).
## Command line interface
You can extract all resources embedded in the executable by running it from the command line with the `--extract-resources` flag. The resources will be extract in the current working directory. Note that the game will use the resources on disk first if they are available.
