void	PushToHistory (string entry)

	This is a default unity function, it is called when the object is instantiated into the scene
void	SetColor (string coords, Color color)
	Set color of a tile based o it's coordinates
IEnumerator	DownloadAndParseGridData (string url)
	Download and parse the API
void	GenerateGrid (ParsedData parsed)
	Generate grid based on the parsed API

Vector3	FromLetterNumberToVector (string letterAndNumber)
	Transform letter and number coordinate system to a Vector to be used by Unity later
CachedPath	FindAllPathsFrom (string startPosition)
	Find all paths to the start position using Dijkstras algorithm This is necessary because the API only have seconds instead of distance, which we can use as weight if we had distance information, we could use A* which is more effective

Detailed Description

The 2D grid that will be used for the path finding

Member Function Documentation

GetNeighbors()

Dictionary< string, float > DroneGame.Grid.GetNeighbors ( string  coordinates )

private

Get all neighbors of the tile

GetOrCreateTile()

TileData DroneGame.Grid.GetOrCreateTile ( string  key )

inlineprivate

Return an already created tile or create a new one if a tile with the coordinates does not already exist

Parameters

key	The coordinate in the format A2

Returns

A brand new or already existing Tile

GetShortestPath()

PathReturn DroneGame.Grid.GetShortestPath ( string  startPosition, string  endPosition  )

inline

Find the shortest paths between start and end using Dijkstras algorithm All paths to start node are automatically cached so if it is asked again, there's no need to recalculate it

MoveDrone()

void DroneGame.Grid.MoveDrone ( )

inline

This is meant to be called from a button in the UI This method does:

• Set some colors for a couple tiles
• Get inputs from the UI
• Call the pathfinding functions
• Start the drone Coroutine that makes it move
