As we use Gradle, there's no need to download libGDX itself – this can all be done by your favorite build tool. We also offer a setup tool, which automatically creates a project for you and downloads everything necessary. See our website for instructions on how to get started with this or read our wiki. We also provide javadocs online. The javadocs are bundled with every libGDX distribution for consumption in your favorite IDE.

QUESTION
I'm trying to use the Android String Resources for an LibGDX Project.
Unfortunately, I can only access the getString()
-Method and the R
class from the android package.
What can I do to access them from also the core package?
Or is it even better to use another solution for translation files?
...ANSWER
Answered 2022-Mar-23 at 23:10Three different paths you can take:
Merge your
core
module code into theandroid
module and simply don't usecore
. The downside with doing this is you will lose the ability to easily test on your desktop (it's faster to compile a desktop build for rapidly testing code changes), and you lose the ability to port to other platforms like desktop and iOS.Use libGDX's localization classes to manage your strings in different languages, instead of Android resources. There are instructions on how to use it here. This is the easiest solution, and it keeps it cross-platform.
Maybe you could write some kind of Gradle task that extracts your String IDs from the generated R class each time you build your Android module, and makes copies of them available in a Java class in your core module, and uses them to retrieve Strings from the XML through some kind of interface. This is the super difficult solution.
QUESTION
Just installed libGDX & android studio yesterday. My boss wants to use libGDX & javaFX (for UI) together in a project.
My assumptions: It sounds like I can do that by using a canvas. LWJGL3 does not support a canvas backend. So i need to use the legacy LWJGL2
My question: How in an existing project do I add legacy support and the libraries?
My current compile is failing with: error: package com.badlogic.gdx.backends.lwjgl does not exist import com.badlogic.gdx.backends.lwjgl.LwjglAWTCanvas
...ANSWER
Answered 2022-Mar-23 at 00:25There are instructions here for migrating from lwjgl2 to lwjgl3, so you can follow them in reverse.
Basically, change your module's dependency from com.badlogicgames.gdx:gdx-backend-lwjgl3
to com.badlogicgames.gdx:gdx-backend-lwjgl
and change your launcher class to use LwjglApplication instead of Lwjgl3Application. The associated application configuration class works a bit differently, too. It uses public fields instead of setter methods.
QUESTION
Currently I have a game in libgdx that show ads on top of the game layout. However, as you can notice, it hides part of the top of the screen, where the score is shown.
Question: How can I make the ads show ABOVE the game view/screen, so it doesnt overlap/hides anything from the game? I want the screens to be as shown in the next picture.
Current code:
...ANSWER
Answered 2022-Jan-24 at 13:01To avoid this overlapping effect using a RelativeLayout
you can create an Ad Container
(eg: a RelativeLayout Container) to be on the top of the screen by using the RelativeLayout.ALIGN_PARENT_TOP
rule and add the GameView
below of the Ad Container using the RelativeLayout.BELOW
rule. Finally add your AdView
as a child of the above Ad Container
.
Below is an example of how you can do the above structure:
QUESTION
I know this questions is not related to programming but I can't find the root problem of my proxy/host.
Ok, let me explain, I am in China, so I have to make use of a VPN. The software is called SSTap and because of that reason I called the host in the same way.
For the project I am trying to make I am using LibGDX and gradle ofc.
After not being able to settle a proxy I removed it, as shown in the picture it is selected as "no proxy" and there are no proxy settings, and down in the output I am getting the warning.
Is there another place to totally remove the host?
I am using "Product Version: Apache NetBeans IDE 12.3"
Thanks in advance I will write down more questions
ReEdit part:
Sorry I thought it was loaded
The warning is: Warning: Failed to parse host SSTap
The way I configure the host/proxy was in a pop-up window that have not appeared anymore and I am unable to find it after setting the host again, the only way that I know to see the host is by Tools -> Options -> General Tab, the picture is not complete but that is the path to get there
I am having difficulties to load the picture, I am in China and I am using a VPN, so it is quite hard to visualize it, since I created the account yesterday I am unable to post pictures and instead they are added by links automatically

QUESTION
I've been learning about libgdx recently. In the process of following the instructions on their libgdx wiki I ran into some problems.
Specifically in the GameScreen class at the 99th line I changed the code inside so that it goes back to the previous screen (MainMenuScreen class) and yes you see when the mouse is pressed it worked (I mean go back to the screen before ) but a very very short time after, the screen AUTOMATICALLY switches to the GameScreen class (like I click the mouse once but it makes me 1 more redundant task). I guess when I click on the GameScreen screen it did the code in the if statement on line 99 to go to MainMenuScreen screen. In that screen at line 32 I guess it was true after I got to this screen because when I change the key is listened then it works fine (only converts once). I was intending to try implementing InputProcessor on each screen class but now I'm avoiding it for some reason. Can someone give me some advice recommend.Thank you
Here is the source code for the MainMenuScreen class.
...ANSWER
Answered 2022-Jan-11 at 06:29Your analysis of the problem seems correct to me. The method Gdx.input.isTouched()
will immediately return true, if the screen is still being touched after you changed to the main menu.
Also you the solution that you already tried seems correct:
I was intending to try implementing InputProcessor on each screen class
When using an InputProcessor
you will get one event (the method call to touchDown
or touchUp
) when the screen is touched, and don't need to pull the touch event using the isTouched
method.
A problem when implementing InputProcessor
with both classes probably is, that you can only set one to be the input processor of the game using the method Gdx.input.setInputProcessor
. (When setting the second input processor, the first one is removed).
A solution to this problem is the InputMultiplexer. You can add this multiplexer as the input processor of the game (using Gdx.input.setInputProcessor(multiplexer)
) and then add your input processors (the main menu and game objects) to this multiplexer: multiplexer.addProcessor(mainMenu)
or ((InputMultiplexer) Gdx.input.getInputProcessor()).addProcessor(game)
.
This way you can handle touch events instead of pulling the touched state in both of your classes.
QUESTION
I'm using libgdx scene2d to render 2d actors. Some of these actors originally included scene2d Label actors for rendering static text. The Labels work fine but drawing ~20 of them on the screen at once drops the frame rate by 10-15 frames, resulting in noticeably poor rendering while dragging.
I'm attempting to avoid the Labels by pre-drawing the text to textures, and rendering the textures as scene2d Image actors. I'm creating the texture using the code below:
...ANSWER
Answered 2021-Dec-09 at 16:16I have not tested this, but I think you can enable culling for the whole Stage by setting its root view to use a cullingArea
matching the world width and height of the viewport. I would do this in resize
after updating the Stage Viewport just in case the update affects the world width and height of the viewport.
QUESTION
I'm using LibGDX to render 2d fog-of-war type functionality. This involves drawing a dark rectangle over the entire map with transparent holes in it where you can see the map below. I'm attempting to use OpenGl stencil buffer to create the circular masks, but I can't seem to get the logic correct.
The code below correctly draws the dark rectangle (the fog) but the circular masks are not being stenciled. i.e. the entire map is dark.
...ANSWER
Answered 2021-Nov-29 at 17:54One way you can achieve a fog-of-war effect is by keeping a Framebuffer
that you write transparent pixels to, and then draw that buffer ontop of your game view:
The steps are more or less:
Draw game
Update fog-of-war buffer
Draw fog-of-war ontop of the game

QUESTION
Does anyone know why libGdx can't find the .tsx file? I have have tmx tsx and png in the assets folder under the core folder. In the tmx file, I have the source set to the file path for the tsx file. I made the tsx and tmx file with Tiled if that helps.
Caused by: com.badlogic.gdx.utils.GdxRuntimeException: File not found: Maps in use\tileset_gutter.tsx (Internal)
...ANSWER
Answered 2021-Oct-26 at 04:17If you don't qualify the file reference then it assumes the root folder to be assets
in the android project as works with everything.
Howeover, you can get the FileHandle
of files in the core project with
Gdx.files.internal("data/...
. (where data
is a folder in core/assets
which should be where yours are)
You can switch between how TmxMapLoader
resolves the files, to delegate the FileResolver
of TmxMapLoader
to this internal handler would be.
new TmxMapHolder(new InternalFileHandleResolver())
which delegates to the internal storage location.
QUESTION
I've been following along with the libGDX docs and I'm very new to Gradle and I almost know nothing about it and I ran into a problem that I couldn't fix. I tried fixing the not found problem by applying the plugin and adding classpath to it but it didn't work. Is there any way I can fix it? (Note: the problem is in html/build.gradle)
OS: Win64
IDE: Android Studio
Errors: Caused by: org.gradle.api.plugins.UnknownPluginException: Plugin with id 'org.wisepersist.gradle.plugins.get.GwtSuperDev' not found. (This is when I added the plugin) Plugin with id 'org.wisepersist.gradle.plugins.get.GwtSuperDev' not found.

Answered 2021-Sep-10 at 02:31I think you're using the plugin mentioned here
So you must ensure you copy everything under the correct section like so
Note all the blocks including the apply plugin
should be copied
