问题描述
我想在borderPane上制作多个相同的矩形,以制作游戏墙。每堵墙看起来都一样,大小也一样。我知道图片有效,并且没有其他错误。我使用以下代码添加矩形:
I want to make multiple of the same rectangle on my borderPane to make walls for the game. Each wall is going to look the same and be the same size. I know the image works and that there are no other errors. I use the following code to add the rectangles:
public class Antz extends Application{
public BorderPane borderPane;
public Scene scene;
public Image wallImage = new Image("/recources/images/walls.png");
public Rectangle wall = new Rectangle();
public int[][] walls = {{1,0,0,0,0,1,1,1,0,1,0,0,0,0,0,1,0},
{1,1,1,1,0,1,0,0,0,1,0,1,1,1,0,1,0},
{0,1,0,1,0,0,0,1,0,1,0,0,0,1,0,0,0},
{0,1,0,1,1,1,0,1,0,1,1,1,0,1,0,1,0},
{0,0,0,0,1,0,0,1,0,0,0,1,0,1,1,1,0},
{1,0,1,1,1,1,0,1,1,1,1,1,0,1,0,0,0},
{1,0,1,0,0,1,0,0,0,0,0,1,0,0,0,1,1},
{1,0,1,1,0,1,0,1,0,1,0,0,0,1,0,0,1},
{1,0,0,0,0,0,0,1,1,1,0,0,1,1,1,0,1},
{0,0,1,0,1,1,0,1,0,1,1,0,1,0,0,0,0},
{1,1,1,0,1,0,0,0,0,0,1,0,1,1,0,1,0},
{1,0,0,0,0,0,1,1,1,0,1,0,0,1,1,1,0},
{1,0,1,0,1,1,1,0,1,1,1,1,0,0,0,1,0},
{0,0,1,0,0,0,0,0,0,0,0,1,0,1,0,0,0},
{1,0,1,1,1,1,0,1,1,1,0,1,0,1,1,0,1},
{0,0,1,0,0,0,0,0,0,1,0,0,0,1,0,0,0}};
public static void main(String[] args){
launch(args);
}
@Override
public void start(Stage primaryStage) throws Exception {
buildWindows();
buildWalls();
primaryStage.setScene(scene);
primaryStage.setTitle("Formicidae");
primaryStage.show();
primaryStage.setMinHeight(550);
primaryStage.setMinWidth(700);
primaryStage.setFullScreenExitHint("");
primaryStage.setFullScreenExitKeyCombination(KeyCombination.NO_MATCH);
}
public void buildWindows() {
borderPane = new BorderPane();
borderPane.setStyle("-fx-background-color: #000000;");
scene = new Scene(borderPane, 700, 550);
}
public void buildWalls(){
wall = new Rectangle(wallImage.getWidth(), wallImage.getHeight());
wall.setFill(new ImagePattern(wallImage));
for(int i = 0;i<walls.length;i++){
for(int j = 0;j<walls[i].length;j++){
if(walls[i][j]==1){
wall.setX(j*20);
wall.setY(i*20);
borderPane.getChildren().add(wall);
}
}
}
}
}
我在运行时收到此错误:
I get this error when it is ran:
Caused by: java.lang.IllegalArgumentException: Children: duplicate children added: parent = BorderPane@4a17c25d[styleClass=root]
推荐答案
尝试在 Pane
对象中两次添加相同的 Node
是不正确的行为。
因此,您每次创建对象时都要创建一个新对象。
Trying to add the same Node
twice in the Pane
object is not a correct behavior.So, you have to create new one every time adding object on a pane object.
public void buildWalls(){
wall.setFill(new ImagePattern(wallImage));
for(int i = 0;i<walls.length;i++){
for(int j = 0;j<walls[i].length;j++){
if(walls[i][j]==1){
wall = new Rectangle(wallImage.getWidth(), wallImage.getHeight());
wall.setX(j*20);
wall.setY(i*20);
borderPane.getChildren().add(wall);
}
}
}
}
,我用Google的某些图片测试了该程序。
Well, I tested the program with some image from google.
我不知道您应该如何处理游戏,但这是输出图像。
I don't know what you are supposed to do with your game but here is the output image.
