I have a college project to make game about smasher game with LibGDX, and i made it so that when the player life is 0, it switch to EndGameScreen class from the GameScreen class, but this happens failed render, I'm actually not sure if it's because of the setScreen method or my EndGameScreen class is not right

Are you calling
dispose() in the render method of
GameScreen? Instead call when the screen is hidden.
dear stackoverflow community,
I have now idea, how i can create a Low-Poly 3d Terrain in Libgdx,
By googling i found remains from the libgdx blog or website they can't help me, but by the research nothing what can help me.
I create a Value Noise but it does not work and i think its not the right way to do it.
Do you know a good tutorial or websites? ^^...

You need to use an AssetManager. By loading the atlas in the assetManager you can easily get access to textures without the need to reload them every time you instantiate the screen. See https://www.gamedevelopment.blog/asset-manager-libgdx-tutorial/

I don't know if this will work but you can try this
I am kinda new to Java and LibGdx but for my school project I need to Animate a Player-Sprite. For only one Animation per Player everything went fine with the Methode I made for this but now I also need a Walking, Idling and Fighting Animation. I managed to get the Animations to switch but the Problem is now, that only one Frame of each Animation gets Displayed. After some research I know that I need to stop updating my Textures every frame but I cant get to know how to do so. So far Ive tried a simple timer before updating but this just looks weird. Here is my Code:...

You need to rename first.
img3 looks like it serves the purpose of being the pointer to the currentTextureSet. so when you initialise in
Player() you might want to rename
currentTextureSet and then, instead of the duplicate load of
currentTextureSet = img;
(you may also want to rename
That aside, definitely get rid of Timer.schedule which you are calling from render will run in a background thread you don't want that.
Looking at the asset pack here https://o-lobster.itch.io/platformmetroidvania-pixel-art-asset-pack?download if this is the same one, the images should be selected left to right i.e.
x should be incremented not
y. However, it looks like you increment
sprite.setRegion(regions[frame]); and the incorrect array access is swallowed because in a background timer task and the only textureRegion you can access is
 i.e. you just see a single frame.
So dump this
I'm trying to implement a simple AI for a 2D game in libGDX. The AI should make an enemy follow the player if the player is in range and if the enemy can see the player. To determine whether the enemy can see the player I'm using a raycast.
Now my problem is, that the raycast does not seem to collide with a static body in the Box2D world.
(It's just an assumption, that the static body is the problem, because it's working fine with a dynamic body)The Question
Do raycasts in libGDX collide with static bodies by default? Or is there an other way to make a raycast collide with static bodies?
Here the enemy with the raycast AI (the one in the upper left) is not moving towards the player (in the lower right) because there is a dynamic body in between them (the other enemy in the middle), which is correctly colliding with the raycast.
But if I put a static body in between the enemy and the player the raycast won't detect the static body, but only the dynamic body (that should be found later than the static body):
Here the static body in the middle is not detected by the raycast.
I've also tested to use
setSleepingAllowed(false) on the static body, to make sure it's not just sleeping. But that also didn't fix it.
ANSWERAnswered 2021-May-22 at 20:37
In box2d, RayCasts should collide with static bodies, so your problem is probably somewhere else.
Keep in mind that the raycast callback is not reporting the fixtures in order of the distance to the start point. Instead the order is random and you have to handle that in you callback. If this is not the problem, you might want to add some code to the question.
I'm using java to process simulations, If I launch the the simulation from a static main function, everything is deterministic and I get the same simulation each time I hit Run as -> Java application, even if I close and reopen eclipse, which is enough to debug the program.
But when I launch the simulation from a GUI (with libgdx) with the same parameters multiple times, the result does change each time.
I Suspect that the code executed during the GUI is not exactly the same (because I am not a robot) which causes some classes such as HashSet to have non deterministic iterations.
How can I get the same behavior as the static main method?
Any advice would be much appreciated
Edit: as code was asked, there is an instance of the issue:...

Object#hashCodemay vary between runs
Implementations of Java commonly implement that method by hashing the equivalent of a memory address of the object, or some such value. To quote the Javadoc of
The hashCode may or may not be implemented as some function of an object's memory address at some point in time.
While not necessarily so, if the implementation is using a memory-address scheme, one can imagine that successive runs of a console app might end up with the same hash code value on each run. But you certainly should not expect that. To quote the Javadoc:
Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
In contrast to a console app, a GUI app is much more complicated, interacting with the host OS to establish windows, menus, and such. One can imagine here that the objects established on an execution run of the GUI app might result in somewhat different objects, enough so that hash codes calculated from something related to memory layout may well vary between runs.
If I launch the the simulation from a static main function, everything is deterministic and I get the same simulation each time I hit Run as -> Java application
As the last sentence of the above quoted Javadoc says: You may, or may not, get the same hash code on separate runs of your app.
➥ At the end of the day, none of this matters. You should not rely on the same value being returned from
hashCode method between executions of your app. You can only rely on the same hash code during an execution of the app.
So your question, “How can I get the same behavior as the static main method?”, is moot. You should not be expecting the same hash code between runs. Why not? Because the documentation says so.UUID
Reading between the lines, I guess you are trying to use the hash code value as a permanent unique identifier. That is not the purpose of a hash code.
If you want to specify a UUID value for your object, you can construct one using a factory method that parses the canonical textual presentation as a hex string with hyphen-delimited groupings of digits. You can manually generate a few values with a web site such as this. Or use software to manually generate UUID values.

Your assumptions are correct. GWT compiler works on Java sources. The error message it gives you is correct: There are no Java source code files to be found, you say it yourself that you used Kotlin.
If you want to use GWT, convert to correct Java source code.
I'm writing a little
libGDX game. Capturing the cursor with
setCursorCatched(boolean) works perfectly at first (hides the cursor symbol and won't let me escape the window) but then breaks:
- After I enter fullscreen with
Fand then exit with
G, the cursor can escape on all sides.
- After I enter fullscreen with
Fwith 2 monitors, I can also escape to my 2nd monitor.
setCursorPositionevery frame does not mitigate this issue.

You need to use
No vulnerabilities reported
You can use libgdx like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the libgdx component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
