まず、上記のジャックが述べたように、文字列の代わりに列挙型を使用できます。例えば
private enum Objects{ Rock(1),Coin(8),Med(45)...など }
配列では、これらのオブジェクトを文字列ではなく数値として格納できます。
例えば：
boolean stopFlag=false;
do{
//check each element of your world array with the enum and draw it
for(int i=0;i<yourObjectsArray.length;i++)
{
for(int j=0;j<yourObjectsArray[i].length;j++){
switch(yourObjectsArray[i][j])
{
case Objects.Rock: drawRock(i,j);
break;
case Objects.Coin: drawCoin(i,j);
break;
//and so on....
}
}
}
//you can also put this into a separate function as drawWorld() and pass the objects.
//Key press checking logic here. If user presses exit key [esc] then you set the stopFlag as true
if(keypress==KEY_ESC){ stopFlag=true;}
}while(!stopFlag);
ドローロックの例:
private void drawRock(int i,int j){
//i and j are the cols and row values so you need to resolve them to coordinates.
//I am assuming u have a 800*600 screen and you mentioned that your world is 100x100 array. Then each of your object is 8*6 units in size so
xCoord=i*8;
yCoord=j*6;
//So if you have to draw a rock on [10][15] it will resolve as
//xCoord=10*8-> 80
//yCoord=15*6-> 90 so it will draw your rock in (80,90) on the screen
//Now you can either open the rock image from your disk now or u maintain one instance of rock at the beginning of the program so that you can use the same image later rather than opening it everytime you encounter a new Rock object in your array.For now I will open it here.
String path = "C:\\YourGameDirectory\\rock.jpg";
URL url = new File(path).toURI().toURL();
BufferedImage rockImg = ImageIO.read(url);
//draw it to the screen now if you have the graphics instance.
yourUIPanel.getGraphics().drawImage(rockImg,xCoord,yCoord,yourUIPanel);
// You may find many resources that teach you how to draw an image on the screen in Java. You may repeat the same for all the objects.
}
上記のコードがお役に立てば幸いです。そうでなければ、それは私の悪いことです。
