Detailed Description

This class models the behaviour of an enemy.

It inherits from KGrRunner.

An enemy's main functions are running, chasing the hero and collecting or dropping gold. If he comes to a dug brick, he must fall in and give up any gold he is carrying. If he is trapped in a closing brick, he dies but reappears elsewhere on the grid.

Constructor & Destructor Documentation

KGrEnemy::KGrEnemy	(	KGrLevelPlayer *	pLevelPlayer,
		KGrLevelGrid *	pGrid,
		int	i,
		int	j,
		int	pSpriteId,
		KGrRuleBook *	pRules
	)

The constructor of the KGrEnemy class.

Parameters

pLevelPlayer	The object that owns the enemy and will destroy him if the KGoldrunner application is terminated during play. The object also provides helper functions to the enemies.
pGrid	The grid on which the enemy is playing.
i	The starting column-number (>=1).
j	The starting row-number (>=1).
pSpriteId	The sprite ID of the enemy, as used in animation.
pRules	The rules that apply to this game and level.
pRandomGen	Random number generator: used to decide when to pick up or drop gold.

Member Function Documentation

Direction KGrEnemy::direction ( )

inline

Returns the direction in which the enemy is running: used for avoiding collisions with other enemies.

Definition at line 274 of file kgrrunner.h.

int KGrEnemy::getPrevInCell ( )

inline

Returns the ID of an enemy who already occupied the same cell (or -1).

Definition at line 279 of file kgrrunner.h.

bool KGrEnemy::isFalling ( )

inline

Returns true if the enemy is falling.

Definition at line 292 of file kgrrunner.h.

void KGrEnemy::run

(

const int

scaledTime

)

Makes an enemy run, guided by the position of the hero and the layout of the grid.

The method is invoked by a periodic timer. If the enemy is trapped in a brick, he reappears somewhere else on the grid, depending on the rules for the game and level. While running, the enemy picks up and randomly drops gold. If he comes to a dug brick, he must fall in and give up any gold he is carrying. He can climb out after a time: or the hole might close first. Otherwise the method changes the enemy's position as required, avoids collisions and decides the type of animation to display (run left, climb, etc.).

Parameters

scaledTime

The amount by which to adjust the time, scaled according to the current game-speed setting. Smaller times cause slower running in real-time: larger times cause faster running.

Definition at line 378 of file kgrrunner.cpp.

void KGrEnemy::setPrevInCell ( const int  prevEnemy )

inline

Sets the ID of an enemy who already occupied the same cell (or -1).

Parameters

prevEnemy

The sprite ID of the previous enemy (or -1).

Definition at line 286 of file kgrrunner.h.

void KGrEnemy::showState

(

)

Implements the author's debugging aid that shows the enemy's state.
