Detailed Description

Handles the tile map.

Takes care of a simple tile based map

Member Function Documentation

int Map::CalculateIndex	(	int	x,
		int	y,
		int	w,
		int	h
	)		const

Calculate the index of the tile at the point

Parameters

x	The point's x coordinate
y	The point's y coordinate

Returns

The index of the tile at the point

Exceptions

Runtime

Error if the point is off the map, must catch this

std::set< int > Map::CalculateIndex

(

Recti

area

)

const

Calculate the indices of all the tiles within an area

Parameters

area	The area to get tile indices in

Returns

A set of ints containing the tile indices

Exceptions

Runtime

error if the set is empty

void Map::Draw

(

std::weak_ptr< Camera >

cam

)

Draw the tiles on the screen, relative to the camera

Parameters

cam	The camera so we can get the offsets/check if things are in camera

void Map::GenerateStressMap

(

Json::Value

val

)

Generate a stress testing map with a specified number of tiles

Parameters

val	The Json::Value to load the stress test from

CollisionMap Map::GetCollisionMap	(	const Recti &	target,
		int	distance = 2
	)

Get the collision map within distance of the target

Parameters

target	The target to get the nearby collision map around
distance	The distance in tiles to return the map of

Returns

The collision map of local tiles

void Map::Load

(

Json::Value

val

)

Load the map from a Json::Value

Parameters

val	The Json::Value to load from

void Map::Load

(

const std::string &

file

)

Load the map from another file

Parameters

file	The file to load the map from

Json::Value Map::Save

(

)

Save the map data to a Json::Value

Returns

The map data as a Json::Value
