Thread: Robot Game; Few errors (help)

Hey there!

I've been following a tutorial on making a game on Kilobolt, but the place is quite dead.
So I've searched for a more active forum.
I hope you guys can save me out of this one

This is my first app ever, so I'm not very familiar with coding.

I've been following this tutorial:
(I want to post the link but the forum won't let me.) -> Kilobolt.com -> Tutorials > Game Development Tutorials > Unit 4 > Day 7 - Creating an Android Game (From Start to Finish)

But I end up getting these errors: Help.jpg

I've changed all the statements from com.kilobolt.robotgame to my own, com.MertensMobile.AndroidSoldier

Which fixed the errors I got when adding the classes (Animation.java, Assets,java etc.)

This is what I get now.

What am I missing?



Ty all very much!

Welcome to the Forum! Please read this topic to learn how to post code correctly and other useful tips for newcomers.

Copy and paste errors directly into a post, if possible; post code in code tags as described in the above link. The picture you posted is next to impossible to read.

Good luck!

Update: The linked picture is much better, though I'm not sure what useful info it provides.

(I fixed the Map1.text - error.)


Sorry.

Thank you for informing me

The code from the SampleGame.java which gives an error:

package com.MertensMobile.AndroidSoldier;
 
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
 
import MertensMobile.R;
import android.util.Log;
 
import com.kilobolt.framework.Screen;
import com.kilobolt.framework.implementation.AndroidGame;
import com.MertensMobile.AndroidSoldier.R;
 
 
public class SampleGame extends AndroidGame {
 
    public static String map;
    boolean firstTimeCreate = true;
 
    @Override
    public Screen getInitScreen() {
 
        if (firstTimeCreate) {
            Assets.load(this);
            firstTimeCreate = false;
        }
 
        InputStream is = getResources().openRawResource(R.raw.map1);
        map = convertStreamToString(is);
 
        return new SplashLoadingScreen(this);
 
    }
 
    @Override
    public void onBackPressed() {
        getCurrentScreen().backButton();
    }
 
    private static String convertStreamToString(InputStream is) {
 
        BufferedReader reader = new BufferedReader(new InputStreamReader(is));
        StringBuilder sb = new StringBuilder();
 
        String line = null;
        try {
            while ((line = reader.readLine()) != null) {
                sb.append((line + "\n"));
            }
        } catch (IOException e) {
            Log.w("LOG", e.getMessage());
        } finally {
            try {
                is.close();
            } catch (IOException e) {
                Log.w("LOG", e.getMessage());
            }
        }
        return sb.toString();
    }
 
    @Override
    public void onResume() {
        super.onResume();
 
        Assets.theme.play();
 
    }
 
    @Override
    public void onPause() {
        super.onPause();
        Assets.theme.pause();
 
    }
}

The other error I'm getting is from the AndroidManifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
   package="com.MertensMobile.AndroidSoldier"
   android:versionCode="1"
   android:versionName="1.0" >
 
    <uses-permission android:name="android.permission.WAKE_LOCK" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.VIBRATE" />
 
    <uses-sdk
       android:minSdkVersion="8"
       android:targetSdkVersion="17" />
 
    <application
       android:icon="@drawable/icon"
       android:label="RobotGame" >
        <activity
           android:name=".SampleGame"
           android:configChanges="keyboard|keyboardHidden|orientation"
           android:label="RobotGame"
           android:screenOrientation="landscape" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
 
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
 
</manifest>

The error here is "@drawable/icon"

--- Update ---

If you need more information, let me know and I'll post it.

I recommend reading up on Android resources. @drawable/icon is trying to reference an image called 'icon.png' in the drawables directory which probably doesn't exist. map1.txt should be formatted as xml in strings.xml (which lives in the values directory). When you reference R.id.something you are trying to access an id of a layout or UI component specified in the res directory.

I've checked it, and I do have an Icon.png in the map Android Soldier\res\drawable-hdpi, like mentioned in the tutorial.

The map1.txt is fixed (how do I format it in strings.xml?)

Icon.png or icon.png... It's case sensitive. Your IDE should be able to autocomplete this for you.

<string name="map1">
    All your strings belong to us..
</string>

Then access that string with

String map = getResources().getString(R.string.map1);

No need to mess around with that InputStream

Why is it in /res/raw? Images live in /res/drawable. Also, I'd recommend sticking to the conventions in the android docs with naming resources. I stick to "ic_launcher" for the applications icon.


You'll notice a couple of different drawable directories (hdpi, xhdpi, etc). These relate to the different screen resolutions. If you plan on supporting multiple devices you need an icon for each directory. There is a breakdown of the sizes here. There are also online tools to automatically scale things for you. You can ignore these and just stick it in drawable for now.

I just got that from the tutorial, where it said "icon.png"

(I changed all the 3 maps with an "icon.png"-file, but no improvement so far.

Could you please re-upload the correct version, cuzz I'm not following it

Tutorials are okay I suppose but the Android docs have the final say. Stick with ic_launcher.

Nope. I'm here to help and guide, not solve your problems for you. Doing so would deprive you of the experience of solving your own problems. Additionally, I don't download .exe files from suspicious file hosts (even if I was running a windows machine).

As of now, I fixed the problems, I get no errors (except for the yellow /!\, doest that matter?

These are warnings. Hover your mouse over the icon to see what the warning is about. Usually it makes sense to fix the problems that generate warnings because the warnings are there for a reason.

I'm drivin nutz here

The warnings from the ArrayList are because they aren't using generics. This is the correct way of defining an ArrayList with type safety ensuring it will only accept objects of a certain type (for example this will only accept String objects).

List<String> tileArray = new ArrayList<String>();

As for that error. It looks like there is a missing permission. Try adding this to the manifest

<uses-permission android:name="android.permission. ACCESS_NETWORK_STATE" />

I give up, I can't get it working.

Ty anyway.

I've had a look at the tutorial you've been following. It's not a tutorial, rather a set of copy and paste instructions. Understand that creating a game for Android is a complex undertaking, requiring a solid grasp of Java concepts and the problem solving skills that only come with experience.

I'd advise you to start small and work up. Have you written a "Hello, World" app? A box that bounces around a canvas? A non-trivial app that serves a purpose? If not then you are not ready to make a game.

You're right.

I followed your advice on it.

I just made my first "Hello World"-app, at least this one works!

So I guess, the next step is the bouncing box
