I am trying to run a linux game on my chromebook(the game can be found here https://bitbrain.itch.io/cave/download/eyJleHBpcmVzIjoxNjM3MjU1OTkwLCJpZCI6NzExNTc5fQ%3d%3d.hggqT%2fhX%2bV6ybeo2kdXBWZa4xCQ%3d) I have executed the following commands: sudo su /cave.x86_64

however, when I run the last command, I just get an error saying that no such file or directory exists. Please help me.

I have a weird problem and cant seem to fix it

i was creating my first game in unity and i was testing around a bit after creating a movement system and whenever i touch another object (it doesnt matter if it has a rigidbody or not) my player suddenly starts moving on its own.

i have a video showing what exactly happens: https://youtu.be/WGrJ0KNYSr4

i have tried a few different things already and i determined that it has to do something with the physics engine because it only happens when the player isnt kinematic, so i tried to increase the solver iterations for physics in the project settings but the bug was still happening so i looked for answers on the internet yet the only thing i found was to remove Time.deltaTime tho it still didnt work. I have found that it seems to happen less though when the player is moving fast.

i would really appreciate if somebody could help me with this since its my first real game and im creating it for the Seajam thats happening on itch.io.

here is the code for my playercontroller script:

let me preface this question by saying I have no idea if I'm asking the right question. I'm pretty new to c++ and I haven't gotten all of its nuances down yet, but I have coded in other OOP languages for nearly 7 years.

I originally asked: Is there a way to take a text file and automatically generate c++ code? If yes, how do I do that? What are some resources that explain the process?

but to clarify, what I really want is: Is there some way to take a text file, or other file type (like json) and use it to generate a compiled c++ class, or other compiled object, that can be interfaced with c++?

The final result doesn't need to be human readable, and it can be system specific. I want to be able to do this at compile time. It does not have to happen at run time. I will know at run time what classes I need. It's just that the classes I will be making (and there will be a lot of them) are all very similar, and just deviate in a few key places. So I want a way to tell the computer the important stuff (which may only take 5 or 6 lines of code), and have it generate the other 30 lines of boiler plate code.

I'm making a game engine, and I am trying to design a system that allows me to plug and play with systems, without having to write a lot of boiler plate code.

Someone commented that I should make the example simpler. So here goes.

I'm trying to build a system that takes a text file input and builds me a compiled c++ binary. It doesn't have to be a text file, and it doesn't have to be specifically c++, as long as it can interface with c++ (relatively easily). This is to decrease the amount of boiler plate code, and number of short kinda useless c++ files that are all almost identical.

For example having a file called example.txt which looks like this.

GOAL
So I have a space-invaders type game I have made to practise unity and I want to upload it to Itch.io as I have done in the past. This is a clip of the game.
I switched platforms to WebGL in Build Settings etc, and everything worked fine in Unity.

PROBLEM
However when I built it and uploaded the zip file to Itch.io, the aliens are now a lot faster than usual.
(Be aware there may be other things that have changed, I just haven't been able to get to them since it is extremely hard).

CODE

Alien movement:

I am working on my new unity project to release it on itch.io. When I write this code that my friend gave me (he is also making a platformer) it gives me the same error:

Assets\Scripts\PlayerMovement.cs(13,57): error CS1061: 'Rigidbody2D' does not contain a definition for 'Velocity' and no accessible extension method 'Velocity' accepting a first argument of type 'Rigidbody2D' could be found

I don't know what all of this means.

So yesterday I finished my first game for a gamejam, I build it and uploaded it to itch.io. But when I got back to that todat I saw a message of someone who said that my player movement didnt work, while it did inside unity itself. After playing the build I also noticed that is doesnt work. But I just cant find out why not, so what are possible that make it dont work.

I'm working on the full version for a puzzle platformer I made, where you switch between players, and in this case(or problem, idk), carry other players that aren't being controlled.

Basically I want the controlled player to be able to carry another player on it's head, and stil be able to jump as high. In the game jam version, I just set the rigidbody mass to zero and made the velocity the same as the cube under it. But now, if I do that, whenever I move, the player on top gets flung extremely fast and teleports around. Not exactly what I wanted.

I've tried making them both apply force for moving and jumping, but the top one jumped of the bottom one, and then they met in the air and the top one jumped again. I also tried using a fixed joint, but the movement was way too fast and broken, and they stuck together too well. I tried applying more force, but the top cube just jumped really high. I just can't win.

On top of that, whenever the top cube falls on the bottom cube in the air, the top one almost bodyslams the bottom one into the ground - they fall really quickly.

What I want is for the top cube to sit nicely on the bottom cube WITHOUT GOING HIGHER THAN THE BOTTOM CUBE, just sitting on it, without making the jump lower, but to also easily be removed by a block pushing it off, and the bottom player jump going under it.

EDIT: Tried parenting the cube did not work, instead I got wierd glitches.

EDIT 2: I tried FixedJoint2D with a slightly different setup, and sometimes it works, but other times it breaks for no reason and the movement is wierd. Like... You're not supposed to jump that high. Code:

I had built a website as a dashboard (using 000webhost) to change the data in mySQL database via php which was working fine right now. After that, I have a Unity WebGL build uploaded on itch.io which was working fine as well until it need to get data from the database via php. When I was intended to get the data via accessing php files store in the 000webhost server, I got the following error show up in the web console from the accessing website.

Mixed Content: The page at 'https://.itch.io/' was loaded over HTTPS, but attempted to connect to the insecure WebSocket endpoint 'ws://:54998/'. This request has been blocked; this endpoint must be available over WSS

The link I was using to access the php files was using https instead of http. I am still new to these area, I would like to know can I change the WebSocket endpoint to wss instead of ws? Do I need a paid plan to solve this? I did saw that the Single Hosting plan did offer free SSL certificate. Please help me, I am open for any suggestion/advice, Thank You.

When there's no obvious compiled jars provided on a github project page, I've been downloading the clear code and kludging them into subdirectories in my codebase to make use of third party code (or, most of the time, just not using the code at all). I know that's not the right way to go about this; what is?

There's a popular post about importing github projects into Eclipse: Importing a GitHub project into Eclipse ...and I've recently learned how to make my own projects depend on one another. Is this the practice, then, to fill up your workspace with projects you're not actually going to work on, so that you can declare dependencies? I remember making dependency references to web resources in the past (itch.io, maybe?) in some configuration, where I didn't have to go download the code. Is there a more elegant solution like that for github?

I'm using Eclipse, and the current library I'd like to use is: https://github.com/FasterXML/jackson
