将Android Studio与AndEngineTMXTileExtension一起使用时出现TMXLoader错误

尼尔·帕特尔

我正在尝试创建类似游戏的塔防。我已使用“平铺地图编辑器”创建了平铺等距地图，并将其保存为android studio中的资产文件夹。我目前正在使用andengine在我的活动中加载地图。

我的MainActivity.Java：

package com.example.neelpatel104.towerfinisher;


import org.andengine.engine.Engine;
import org.andengine.engine.LimitedFPSEngine;
import org.andengine.engine.camera.BoundCamera;
import org.andengine.engine.options.EngineOptions;
import org.andengine.engine.options.ScreenOrientation;
import org.andengine.engine.options.resolutionpolicy.RatioResolutionPolicy;
import org.andengine.entity.scene.Scene;
import org.andengine.entity.util.FPSLogger;
import org.andengine.extension.tmx.TMXLayer;
import org.andengine.extension.tmx.TMXLoader;
import org.andengine.extension.tmx.TMXProperties;
import org.andengine.extension.tmx.TMXTile;
import org.andengine.extension.tmx.TMXTileProperty;
import org.andengine.extension.tmx.TMXTiledMap;
import org.andengine.extension.tmx.util.exception.TMXException;
import org.andengine.extension.tmx.util.exception.TMXLoadException;
import org.andengine.opengl.texture.TextureOptions;
import org.andengine.ui.activity.SimpleBaseGameActivity;
import org.andengine.util.debug.Debug;

public class MainActivity extends SimpleBaseGameActivity  {
private TMXTiledMap mTMXTiledMap;
    private TMXLayer tmxLayer;
    private static final int CAMERA_WIDTH=550;
    private static final int CAMERA_HEIGHT=300;

    private BoundCamera mBoundChaseCamera;
    protected int mCactusCount;

@Override
public Engine onCreateEngine(EngineOptions engineOptions){
    return new LimitedFPSEngine(engineOptions,60);
}
    @Override
    public EngineOptions onCreateEngineOptions(){
        this.mBoundChaseCamera = new BoundCamera(0,0,CAMERA_WIDTH,CAMERA_HEIGHT);return new EngineOptions(true,ScreenOrientation.LANDSCAPE_FIXED,new RatioResolutionPolicy(CAMERA_WIDTH,CAMERA_HEIGHT),this.mBoundChaseCamera);
}

    @Override
    protected void onCreateResources() {
    final TMXLoader tmxLoader = new TMXLoader(getAssets(),getTextureManager(),TextureOptions.NEAREST,mEngine.getVertexBufferObjectManager());
    try {
       this.mTMXTiledMap = tmxLoader.loadFromAsset("map/levelone.tmx");
   } catch (final TMXLoadException e){
            Debug.e(e);
        }
    }

    @Override
    protected Scene onCreateScene() {
       this.mEngine.registerUpdateHandler(new FPSLogger());
        final Scene scene = new Scene();
        this.tmxLayer = this.mTMXTiledMap.getTMXLayers().get(0);

        scene.setChildrenVisible(false);
        scene.setBackgroundEnabled(false);
        scene.attachChild(this.tmxLayer);

        return scene;
    }

}

下面的行给我一个错误：

 final TMXLoader tmxLoader = new TMXLoader(getAssets(),getTextureManager(),TextureOptions.NEAREST,mEngine.getVertexBufferObjectManager());

这是我完整的堆栈跟踪：

我不明白问题是什么。每当我尝试调试程序时，都会出现此错误。我什至尝试重新安装andengine和TMXTiledMAP扩展，但是错误始终存在。我希望有人来看看。

谢尔盖·S。

构建失败，因为某些类和方法在最新版本中已弃用。您可以尝试减少andengine build.gradle文件的compileSdkVersion。您还可以通过简单的更改来解决大多数这些错误：

通过使用标准Math类更改所有数学调用，例如sin，cos，floor，sqrt，ceil等：将FloatMath.sin（）替换为（float）Math.sin（），其他方法类似。

要修复org.apache.http软件包不存在的错误：将useLibrary'org.apache.http.legacy'添加到andengine build.gradle文件中：

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0'
    }
}

apply plugin: 'com.android.library'

android {
    compileSdkVersion 23
    //buildToolsVersion '26'
    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }
    }
    useLibrary 'org.apache.http.legacy' //for support 23+ sdk
}
...

不推荐使用类voidXfermode，因此请按照上面的代码设置compileSdkVersion 23。如果有人以其他方式描述如何在不降低compileSdkVersion的情况下修复避免Xakemode，我将不胜感激。
