Detailed Description

Parent class for elements in the map.

Only child classes should be used A MapElement is the basic unit in Map. It contains information about is location, HP and etc, as well as methods that provides basic attack and move methods. In addition to that, it also contains information about its graphical representation.

Extended by Creature and Cube

		int	x,
		int	y,
		int	z,
		int	damage
	)

Helper for calling attack(int x,int y,int z,int damage)

Parameters

old	IntVec3 that contains the coordinate
x,y,z	offset to IntVec3 old
damage	Damage dealt

bool MapElement::attackDiscoBall ( int damage )

Attack the Disco Ball!!!!

Parameters

damage Damage to Disco Ball

bool MapElement::boundaryCheck	(	int	x,
		int	y,
		int	z
	)

Check if this position is in the Map grid in order to avoid bad access.

Parameters

x,y,z point to be checked

AABox MapElement::getAABox ( )

virtual

Get the AABox corresponding to the creature.

Has to be virtual because size vary

int MapElement::getBounty ( )

virtual

Returns: the bounty of it when killed, applicable to only Creature

Reimplemented in SuperCrawler, Bomber, Archer, SmartCrawler, Creeper, Crawler, and Creature.

int MapElement::getOccupancy ( )

virtual

Returns: the occupancy of it

Reimplemented in SuperCrawler, Bomber, Archer, SmartCrawler, Creeper, Crawler, Creature, BasicTower, and Cube.

int MapElement::getType ( )

virtual

Returns: the type of it

Reimplemented in SuperCrawler, Bomber, Archer, SmartCrawler, Creeper, Crawler, Creature, BasicTower, and Cube.

bool MapElement::hasBox	(	int	x,
		int	y,
		int	z
	)

Check if there is a box at the specified position.

Parameters

x,y,z position to be checked

bool MapElement::hasBox ( IntVec3 v )

Helper for calling hasBox(int x, int y, int z);.

Parameters

v	IntVec3 of the position

bool MapElement::inMap ( )

Check if the MapElement is close to the Disco Ball.

Parameters

v	position of MapElement
range	range of attack, in mahattan distance

See Map::discoBallLoc for more infoCheck if the MapElement is inside the map. Used for visualizing the creatures approaching the playable map

bool MapElement::isValidMove	(	int	x,
		int	y,
		int	z
	)

Check if can move to the position Can move if the occupancy of this MapElement sums the gridOccupancy of the destination grid is less than or equal to 100.

Parameters

x,y,z position to be checked

bool MapElement::isValidMove ( IntVec3 v )

Helper for calling isValidMove(int x, int y, int z);.

Parameters

v	IntVec3 of the position

bool MapElement::isValidMove	(	IntVec3	old,
		int	x,
		int	y,
		int	z
	)

Helper for calling isValidMove(int x, int y, int z);.

Parameters

old	IntVec3 that contains the coordinate
x,y,z	offset to IntVec3 old

bool MapElement::move ( )

virtual

Take a move This is the method that actually determines the behavior of the creature.

Called by run() everytime when turnsLeft = 0;

Must update turnsLeft. Must be overridden in sub classesA

Reimplemented in SuperCrawler, Bomber, Archer, SmartCrawler, Creeper, Crawler, Creature, BasicTower, Cube, and Bullet.

void MapElement::onDeath ( )

virtual

Update m_map when it dies.

Reimplemented in SuperCrawler, Bomber, Archer, SmartCrawler, Creeper, Crawler, Creature, BasicTower, Cube, and Bullet.

void MapElement::onSpawn ( )

virtual

Update m_map when it spawns.

Reimplemented in SuperCrawler, Bomber, Archer, SmartCrawler, Creeper, Crawler, Creature, BasicTower, and Cube.

bool MapElement::operator< ( const MapElement & other ) const

Overloaded less than for sorting.

float MapElement::randFloat ( )

Generates pseudo-random float between 0 and 1.

void MapElement::run ( )

virtual

Called every frame to update the MapElement A MapElement takes a certain number of turns(frames) to finish a move.

Run is called to check if the current move has been finished. Everytime run() is called, turnsLeft is decremented by 1. If turnsLeft equals 0, move() is called to perform the next move

Reimplemented in Bullet.

void MapElement::takeDamage ( )

virtual

Takes damage from the grid for both the oldPos and newPos.

Takes attack damage if a Cube and defend damage if a Creature.

See Map::attackDamage and Map::defendDamage for more info.

Reimplemented in Bullet.

void MapElement::updateHP ( )

Called every frame to update the HP of the MapElement.
