[英]libGDX Strange Rendering Bug
I've recently started my first libGDX game, and it is all going well, everything renders fine but after about a minute nothing renders, the rendering calls are still made and the spritebatch works fine, I'm just left with a black screen, I have even changed the 'glClearColor()' to but I'm still left with a black screen. 我最近开始了我的第一个libGDX游戏,一切顺利,一切正常,但是大约一分钟后没有任何渲染,仍然进行了渲染调用,并且spritebatch正常工作,我只剩下黑屏了,我什至将'glClearColor()'更改为,但是我仍然留下黑屏。 I've have no idea what this could be.
我不知道这可能是什么。
My main class: 我的主班:
@Override
public void create() {
Gdx.graphics.setDisplayMode(Settings.screenWidth, Settings.screenHeight, Settings.fullscreen);
Gdx.graphics.setVSync(Settings.VSync);
Gdx.graphics.setTitle("Trench Warfare");
batch = new SpriteBatch(1000);
previous = System.currentTimeMillis();
currentMap = new Map(this, 0);
currentMap.addObject(new ColourMapObject(this, 0));
}
private void update() {Settings.screenHeight, Settings.fullscreen);
Gdx.graphics.setVSync(Settings.VSync);
batch.setColor(new Color(Settings.brightness, Settings.brightness, Settings.brightness, 1.0f));
float delta = ((float)(System.currentTimeMillis() - previous)) / 1000.0f;
previous = System.currentTimeMillis();
currentMap.update(delta);
}
@Override
public void render() { //Always called
update();
Gdx.gl.glClearColor(1, 0, 0, 1); //Red colour still black screen.
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
batch.begin();
currentMap.render(batch); //Basicly list of textures to be rendered, they never stop rendering (Being called) despite black screen.
batch.end();
batch.flush();
}
EDIT: We've determined that after some time SpriteBatch render a black screen over the red clear colour, It also stops rendering the texture. 编辑:我们确定一段时间后SpriteBatch会在红色透明色上渲染黑屏,它也会停止渲染纹理。 I've also determined that the SpriteBatch's tint or colour stays white even during the black screen.
我还确定,即使在黑屏期间,SpriteBatch的色调或颜色仍保持白色。
EDIT, this code takes in a texture and then turns into a different texture with different colours: 编辑,此代码接受纹理,然后将其转换为具有不同颜色的不同纹理:
public class ColourMapObject extends MapObject {
public enum Type {
Dirt,
Water,
Trench,
}
private Texture terrainMap;
private Texture trenchMap;
private Texture soldierMap;
private Texture buildingMap;
private Texture shipMap;
private int levelId;
private Texture finalTexture;
private Type[][] types;
public ColourMapObject(TrenchMain main, int levelId) {
super(main);
this.levelId = levelId;
//finalTexture = new Texture("/map" + String.valueOf(levelId) + "/terrainMap.png");
finalTexture = new Texture("black.png");
finalTexture.getTextureData().prepare();
loadMap(levelId);
}
private void loadMap(int levelId) {
//terrainMap = new Texture("/map" + String.valueOf(levelId) + "/terrainMap.png");
terrainMap = new Texture("terrainMap.png");
types = new Type[terrainMap.getWidth()][terrainMap.getHeight()];
terrainMap.getTextureData().prepare();
Pixmap pixmap = terrainMap.getTextureData().consumePixmap();
for(int x = 0; x < terrainMap.getWidth(); x++) {
for(int y = 0; y < terrainMap.getHeight(); y++) {
types[x][y] = RandomMapColour.getType(new Color(pixmap.getPixel(x, y)));
if(types[x][y] == null) types[x][y] = Type.Dirt;
}
}
// trenchMap = new Texture("/map" + String.valueOf(levelId) + "/trenchMap.png");
//
//
// soldierMap = new Texture("/map" + String.valueOf(levelId) + "/soldierMap.png");
//
//
// buildingMap = new Texture("/map" + String.valueOf(levelId) + "/buildingMap.png");
//
//
// shipMap = new Texture("/map" + String.valueOf(levelId) + "/shipMap.png");
}
@Override
public void update(float delta) {
super.update(delta);
Pixmap draw = new Pixmap(Settings.screenWidth, Settings.screenHeight, Format.RGB888);
float pX = (float)terrainMap.getWidth() / (float)draw.getWidth();
float pY = (float)terrainMap.getHeight() / (float)draw.getHeight();
for(int x = 0; x < draw.getWidth(); x++) {
for(int y = 0; y < draw.getHeight(); y++) {
switch(types[(int)((float)x * pX)][(int)((float)y * pY)]) {
case Dirt:
draw.drawPixel(x, y, RandomMapColour.getDirtColour());
break;
case Trench:
draw.drawPixel(x, y, RandomMapColour.getTrenchColour());
break;
case Water:
draw.drawPixel(x, y, RandomMapColour.getWaterColour());
break;
}
}
}
finalTexture = new Texture(draw);
}
@Override
public void render(SpriteBatch batch) {
super.render(batch);
float sx = ((float)TrenchMain.getScreenWidth()) / ((float)finalTexture.getWidth());
float sy = ((float)TrenchMain.getScreenHeight()) / ((float)finalTexture.getHeight());
batch.draw(finalTexture, 0, 0, 0, 0, finalTexture.getWidth(), finalTexture.getHeight(), sx, sy, 0, 0, 0, finalTexture.getWidth(), finalTexture.getHeight(), false, false);
}
I finally figuired it out, for those who are wonder, what I was doing was creating a new finalTexture
every update with disposing of the old one. 我终于把它弄糊涂了,对于那些想知道的人,我正在做的是在每次处理旧的更新时都创建一个新的
finalTexture
。
Simply dispose of the texture. 简单地处理纹理。
finalTexture.dispose();
