From bbc04275a73aec87d83f264fcf760407363d5c5b Mon Sep 17 00:00:00 2001 From: Starla Insigna Date: Tue, 27 Jan 2009 15:22:34 -0500 Subject: Added parentMap data to Event StepMoveEvent has an issue where an event could walk off the screen under its influence because it preformed no collision checking, due to the fact that the parent map had to be accessable to preform collision checking. Now, both event styles (unified with an AbstractEvent class that handles functions common to both styles) carries information about its parent map, provided by EventList which is in turn provided by the parent map itself. --- .../fourpuzzle/gamestate/mapview/Map.java | 14 ++- .../gamestate/mapview/MapViewGameState.java | 9 +- .../gamestate/mapview/event/AbstractEvent.java | 122 +++++++++++++++++++++ .../fourpuzzle/gamestate/mapview/event/Event.java | 7 ++ .../gamestate/mapview/event/EventList.java | 28 ++++- .../gamestate/mapview/event/HeroEvent.java | 94 ++-------------- .../gamestate/mapview/event/LayerEvent.java | 103 +++-------------- 7 files changed, 195 insertions(+), 182 deletions(-) create mode 100644 src/com/fourisland/fourpuzzle/gamestate/mapview/event/AbstractEvent.java (limited to 'src') diff --git a/src/com/fourisland/fourpuzzle/gamestate/mapview/Map.java b/src/com/fourisland/fourpuzzle/gamestate/mapview/Map.java index 62270bf..bc0073e 100644 --- a/src/com/fourisland/fourpuzzle/gamestate/mapview/Map.java +++ b/src/com/fourisland/fourpuzzle/gamestate/mapview/Map.java @@ -6,7 +6,9 @@ package com.fourisland.fourpuzzle.gamestate.mapview; import com.fourisland.fourpuzzle.*; +import com.fourisland.fourpuzzle.gamestate.mapview.event.Event; import com.fourisland.fourpuzzle.gamestate.mapview.event.EventList; +import com.fourisland.fourpuzzle.gamestate.mapview.event.HeroEvent; import com.fourisland.fourpuzzle.gamestate.mapview.event.LayerEvent; import java.awt.Dimension; import java.util.HashMap; @@ -41,7 +43,7 @@ public abstract class Map { } } - private EventList events = new EventList(); + private EventList events = new EventList(this); public EventList getEvents() { return events; @@ -59,8 +61,11 @@ public abstract class Map { return null; } - public boolean checkForCollision(int x, int y, Direction toMove) + public boolean checkForCollision(Event ev, Direction toMove) { + int x = ev.getLocation().x; + int y = ev.getLocation().y; + if ((toMove == Direction.North) && (y == 0)) { return true; @@ -75,6 +80,11 @@ public abstract class Map { return true; } + if ((ev instanceof HeroEvent) && (((MapViewGameState) Game.getGameState()).debugWalkthrough)) + { + return false; + } + if ((toMove == Direction.North) && (checkForEventCollision(x, y-1))) { return true; diff --git a/src/com/fourisland/fourpuzzle/gamestate/mapview/MapViewGameState.java b/src/com/fourisland/fourpuzzle/gamestate/mapview/MapViewGameState.java index 48653c0..0604dd0 100644 --- a/src/com/fourisland/fourpuzzle/gamestate/mapview/MapViewGameState.java +++ b/src/com/fourisland/fourpuzzle/gamestate/mapview/MapViewGameState.java @@ -29,7 +29,7 @@ import java.util.logging.Logger; */ public class MapViewGameState implements GameState { - boolean debugWalkthrough = false; + public boolean debugWalkthrough = false; boolean processInput = true; Map currentMap; @@ -99,12 +99,7 @@ public class MapViewGameState implements GameState { if (letsMove) { - if (debugWalkthrough || (!currentMap.checkForCollision(hero.getLocation().x, hero.getLocation().y, toMove))) - { - hero.startMoving(toMove); - } else { - hero.setDirection(toMove); - } + hero.startMoving(toMove); } if ((Game.getKey().getKeyCode() == KeyEvent.VK_ENTER) || (Game.getKey().getKeyCode() == KeyEvent.VK_SPACE)) diff --git a/src/com/fourisland/fourpuzzle/gamestate/mapview/event/AbstractEvent.java b/src/com/fourisland/fourpuzzle/gamestate/mapview/event/AbstractEvent.java new file mode 100644 index 0000000..e5334c8 --- /dev/null +++ b/src/com/fourisland/fourpuzzle/gamestate/mapview/event/AbstractEvent.java @@ -0,0 +1,122 @@ +/* + * To change this template, choose Tools | Templates + * and open the template in the editor. + */ + +package com.fourisland.fourpuzzle.gamestate.mapview.event; + +import com.fourisland.fourpuzzle.Direction; +import com.fourisland.fourpuzzle.gamestate.mapview.Map; +import com.fourisland.fourpuzzle.util.Functions; +import java.awt.Point; + +/** + * + * @author hatkirby + */ +public abstract class AbstractEvent implements Event { + + private Point location = new Point(); + public Point getLocation() + { + return location; + } + public void setLocation(Point location) + { + this.location = location; + } + public void setLocation(int x, int y) + { + location.setLocation(x, y); + } + + private boolean moving = false; + public boolean isMoving() + { + return moving; + } + public void setMoving(boolean moving) + { + this.moving = moving; + } + + /* TODO Remove the moveDirection field.
