Advanced tools
grid_engine is a framework for generating and manipulating grids. It provides a number of classes and functions for generating and manipulating grids. Each grid is composed of Cell objects and is defined by a Blueprint. A grid can be generated from a blueprint, loaded from a file, or created manually. It can also be pickled for later use. It can be rendered as a 2D image, an animated GIF or an ASCII string. Grids provide a number of relevant methods for pathfinding, cell manipulation, and more.
To install grid_engine, run the following command:
```bash
pip install gridengine_framework
```
To use gridengine you can import any number of the submodules and utilize its respective features or you can import the main module.
```python
import grid_engine as ge
# Create a grid
grid = ge.grid.Grid(cell_size=10, grid_dimensions=(1000, 1000))
# Save a grid
ge.grid.save_grid(grid)
# Load a grid
loaded_grid = ge.grid.Grid.load_grid(1)
```
grid_engine also provides a command line interface. To use it, run the following command:
```bash
python -m grid_engine --help
# Output:
# usage: gridengine [-h] [-i] [-b BLUEPRINT] [--ascii] [-l LOAD] [-t] [-ns NOISE_SCALE] [-no NOISE_OCTAVES] [-nr NOISE_ROUGHNESS] [-r ROWS] [-c COLUMNS] [-s SIZE] [-S] [-T TYPE] [-v]
# Generate a visualized grid from a blueprint. For producing a blueprint, see the blueprint module.
# options:
# -h, --help show this help message and exit
# -i, --interactive Run an interactive session
# -b BLUEPRINT, --blueprint BLUEPRINT
# Load a blueprint from a file
# --ascii Print the grid as ascii
# -l LOAD, --load LOAD Load a grid from a file
# -t, --terrain Whether to generate terrain with the grid.
# -ns NOISE_SCALE, --noise-scale NOISE_SCALE
# Noise scale
# -no NOISE_OCTAVES, --noise-octaves NOISE_OCTAVES
# Noise octaves
# -nr NOISE_ROUGHNESS, --noise-roughness NOISE_ROUGHNESS
# Noise roughness
# -r ROWS, --rows ROWS Number of rows in the grid
# -c COLUMNS, --columns COLUMNS
# Number of columns in the grid
# -s SIZE, --size SIZE Size of each cell in the grid
# -S, --save Save the grid object to a file
# -T TYPE, --type TYPE Type of file to save the grid as
# -v, --verbose Verbose output
```
The following examples demonstrate the use of the grid_engine package.
The following command:
```bash
python -m grid_engine -v -S -t -ns 400 -no 75 -nr 0.55 -r 450 -c 800 -s 2
```
Will produce the following output:
```bash

The river generation algorithm is not perfect. I am currently working on improving it.
The above command will also produce the following files(Not included in the repository... That is, generate your own!):
grid.cf1b9.pickle
: A pickled Grid object.

: A pickled TerrainGridBlueprint object.
import grid_engine
from grid_engine import Grid
