我正在尝试在 LibGDX 中制作井字游戏，我想从用户玩游戏的屏幕 (PlayGround) 移动到显示结果的屏幕 (End)，但 PlayGround 屏幕中的渲染方法仍然被调用，尽管我已经将屏幕更改为 End。经过调试，我发现只调用了 End 屏幕中的 show 方法，但渲染方法仍然是从 PlayGround 调用的，而不是从 End 调用的。
Playground 代码:
public class PlayGround implements Screen {
MainMenu game;
Stage stage;
Texture gridTex;
Image gridImage ;
TextButton restart ;
TextButtonStyle style ;
String turn ;
SpriteBatch batch;
Zone[] zones = new Zone[9];
End end;
XO game1;
public PlayGround(MainMenu game){
this.game = game;
}
@Override
public void resize(int width, int height) {
}
@Override
public void show() {
game1 = new XO();
end = new End(this);
//Draw Grid
gridTex = new Texture("images/playground/grid.png");
gridImage = new Image(gridTex);
batch = new SpriteBatch();
gridImage.setPosition(40, 100);
//Draw Restart
style = new TextButtonStyle();
style.font = MainMenu.defaultFont;
TextureRegionDrawable drawable =new TextureRegionDrawable(Zone.atlas.findRegion("restart"));
style.up = drawable ;
style.down = drawable ;
restart = new TextButton("Restart",style);
//Create the Zones
zones[0] = new Zone(50, 378);
zones[1] = new Zone(151, 378);
zones[2] = new Zone(251, 378);
zones[3] = new Zone(50, 242);
zones[4] = new Zone(151, 242);
zones[5] = new Zone(251, 242);
zones[6] = new Zone(50, 108);
zones[7] = new Zone(151, 108);
zones[8] = new Zone(251, 108);
restart.addListener(new InputListener() {
public boolean touchDown (InputEvent event, float x, float y, int pointer, int button) {
for(int i = 0 ; i < zones.length ; i++)
{
zones[i].setPlayer(0) ;
zones[i].setClicked(false);
zones[i].getImage().setDrawable(new TextureRegionDrawable(Zone.atlas.findRegion("empty")));
}
Zone.counter = 1 ;
return true;
}
public void touchUp (InputEvent event, float x, float y, int pointer, int button) {
}
});
//Creating the stage and adding actors
stage = new Stage(380, 630, true);
stage.addActor(gridImage);
for(int i = 0 ; i< zones.length ; i++)
stage.addActor(zones[i].getImage());
stage.addActor(restart);
Gdx.input.setInputProcessor(stage);
}
@Override
public void render(float delta) {
//It clears the older screen
Gdx.gl.glClearColor(0, 0, 0, 1);
Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
System.out.println(Zone.counter);
if(Zone.counter%2==0)
{turn = "O's TURN";}
else
{turn = "X's TURN";}
check();
//Drawing the stage and it's children's
batch.begin();
stage.draw();
batch.end();
batch.begin();
MainMenu.title.draw(batch,turn, 114 , 570);
batch.end();
//Fires the listeners
stage.act(delta);
}
public void check()
{
//Horizontal
for(int i = 0 ; i<7;i += 3)
{
if(zones[i].getPlayer()==1 && zones[i+1].getPlayer()==1 && zones[i+2].getPlayer()==1)
{
System.out.println("Player 1 wins");
End.setWinner(1);
stage.clear();
game1.setScreen(end);
}
else if(zones[i].getPlayer()==2 && zones[i+1].getPlayer()==2 && zones[i+2].getPlayer()==2)
{
System.out.println("Player 2 wins");
End.setWinner(2);
stage.clear();
game1.setScreen(end);
}
else if (Zone.counter == 10)
{
stage.clear();
game1.setScreen(end);
}
}
//Vertical :
for(int i = 0 ; i<3;i++)
{
if(zones[i].getPlayer()==1 && zones[i+3].getPlayer()==1 && zones[i+6].getPlayer()==1)
{
System.out.println("Player 1 wins");
End.setWinner(1);
stage.clear();
game1.setScreen(end);
}
else if(zones[i].getPlayer()==2 && zones[i+3].getPlayer()==2 && zones[i+6].getPlayer()==2)
{
System.out.println("Player 2 wins");
End.setWinner(2);
stage.clear();
game1.setScreen(end);
}
else if (Zone.counter == 10)
{System.out.println("Tie");
stage.clear();
game1.setScreen(end);
}
}
//Diagonal LeftToRight
if(zones[0].getPlayer()==1 && zones[4].getPlayer()==1 && zones[8].getPlayer()==1)
{System.out.println("Player 1 wins");
End.setWinner(1);
stage.clear();
game1.setScreen(end);
}
if(zones[0].getPlayer()==2 && zones[4].getPlayer()==2 && zones[8].getPlayer()==2)
{System.out.println("Player 2 wins");
End.setWinner(2);
stage.clear();
game1.setScreen(end);
}
//Diagonal RightToLeft
if(zones[2].getPlayer()==1 && zones[4].getPlayer()==1 && zones[6].getPlayer()==1)
{System.out.println("Player 1 wins");
End.setWinner(1);
stage.clear();
game1.setScreen(end);
}
if(zones[2].getPlayer()==2 && zones[4].getPlayer()==2 && zones[6].getPlayer()==2)
{System.out.println("Player 2 wins");
End.setWinner(2);
stage.clear();
game1.setScreen(end);
}
}
结束屏幕中的代码:
package com.teamthawra.www.Screens;
public class End implements Screen {
static int winner = 0;
SpriteBatch batch;
static Stage stage;
XO game;
MainMenu main;
PlayGround playground;
public End (PlayGround playground) {
this.playground = playground;
}
@Override
public void render(float delta) {
Gdx.gl.glClearColor(0, 0, 0, 1);
Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
System.out.println("Rendering in end");
if (winner == 1){
batch.begin();
MainMenu.title.draw(batch, "X WON!", 114, 570);
batch.end();
}
else if (winner == 2){
batch.begin();
MainMenu.title.draw(batch, "O WON!", 114, 570);
batch.end();
}
else {
batch.begin();
MainMenu.title.draw(batch, "It's a tie", 114, 570);
batch.end(); }
batch.begin();
MainMenu.title.draw(batch, "Press anywhere to continue", 114, 300);
batch.end();
}
@Override
public void resize(int width, int height) {
}
@Override
public void show() {
System.out.println("I am at end");
game = new XO();
main = new MainMenu(this);
stage = new Stage(380, 630 , true);
Gdx.input.setInputProcessor(stage);
stage.addListener(new InputListener() {
public boolean touchDown (InputEvent event, float x, float y, int pointer, int button) {
stage.clear();
game.setScreen(main);
return true;
}
public void touchUp (InputEvent event, float x, float y, int pointer, int button) {
}
});
}
public static void setWinner(int winner) {
End.winner = winner;
}
public static int getWinner() {
return winner;
}
}
抱歉添加了所有代码，因为我是初学者，这是我在 LibGDX 中的第一个程序，我不知道问题到底出在哪里。
最佳答案
我不完全确定，但我最好的猜测是在 game1(XO 类型的新对象)上调用 setScreen() 是问题所在。
如果我是正确的，您应该在为屏幕 PlayGround 调用 setScreen() 的同一个时间游戏对象(或从 LibGdx 的游戏继承的对象)上调用 setScreen() 。
例如，如果您有一个菜单“屏幕”，并且从那里您可以使用以下命令进入 Playground :
game.setScreen(playGroundScreen);
您应该在同一个游戏对象上切换屏幕，如下所示:
game.setScreen(endScreen);
而不是创建一个新变量(就像您对 game1 所做的那样)。
让我知道它是否有效。
关于java - 两种渲染方法在两个屏幕上同时工作，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/20445935/
