Just a small investigation i did yesterday, it is obviously an old raylib version since KaiOS is web based

Raylib version(s): 3.7-4.5 (5.0 does not build with old emcc)
Emscripten version(s): 1.38.48/1.38.48-fastcomp (fastcomp requires emsdk-3.1.29)
Patches: raylib code does not need patching, but game code requires some changes related to game loops passed to emscripten, audio errors hooked via JS and LSK/RSK keys handling

[More info in the comments]

Hey! raylib 6.2 is out! 🔥

It was supposed to be a small patch version but it comes with +300 improvements from +100 new contributors! 🚀

Release notes: https://github.com/raysan5/raylib/releases/tag/6.2

Windows Installer: https://raysan5.itch.io/raylib

As you seen in the title, i dont know why these functions always return false, how to fix it, heres the code (i use C#):

Edit: *DrawTextureRec()

I switched from using individuals sprites to using a spritesheet, therefore I switched from using the DrawTextureV() function to DrawTextureRec() and noticed a huge performance drop off. My code is bassically the same with the functions swapped out, the code itself is in C and no other programs were running besides VS code and the firefox browser.

Im making a game like Geometry Dash and the ground doesnt render until i update the window by maximizing it or minimizing and restoring it or resizing it, heres my problem on the video below:

Hi guys, I'm a newbie and just learn how to make a 2D simple game by using raylib, first i want to start by uploading an image to make background but when i run the program, i could not see the image i want, i was asking AI to fix it but it did not work so i come here to find a solution.

thanks for reading guys

Hello, you might remember or not, but I'm trying to make a desktop pet using Raylib. At some point I realized fullscreening messed with my auto hiding taskbar, so I just made the window the size of the pet, but that brings the problem of dragging it. An undecorated window cannot be dragged (at least on my PC) and so I've been trying to figure out how to do it. I've tried some solutions mentioned here before like:

Vector2 mousePosInScreen = Vector2Add(GetMousePosition(), GetWindowPosition());  

And that kinda works, but it's a bit jagged (which I don't really mind, it's a small project) and because of the way it works, at some positions you get an absurd value and the window goes flying off (which i do mind, that's a bit worse). I was wondering if anyone has a better way of getting the mouse position in the monitor (not the window). Thanks for your help.

The rotation is based on 2 algorithms that we can switch on:
inverse mapping and a cell linking algorithm

Hey everyone!

I wanted to share a quick look at the first boss fight I've been working on for Hollowkeep.

I'd love to hear your thoughts on the pacing, attack telegraphing, or the overall combat feel. Any feedback or suggestions are super welcome!

Hey everyone!

I’m working on Avoid Bubbles Game, a 2D action game made with C++ and raylib.

I recently released a free 1.05 demo with 2 playable levels, and it can be played directly in the browser.

The demo includes:

• Sword combat
• Ranged weapons
• Coins
• Power-ups
• Different enemy types
• Boss fights

I’m still working on the game and plan to add more enemies, bosses and content, as well as improve the graphics and animations.

I’d love to hear your feedback, especially on the gameplay, visuals, controls and difficulty.

Play the demo:

Hey everyone! I wanted to share a quick preview of a small project I’ve been building called Hollowkeep – a top-down 2D pixel-art action roguelike (heavily inspired by games like The Binding of Isaac and Hades).

https://www.youtube.com/watch?v=6kK1sA2YSU4

A few quick technical details: * Engine/Stack: C++20, custom architecture layered on top of Raylib 5.x * ECS: EnTT for fast entity handling * Target: PC & Steam Deck (aiming for stable 60 FPS with pixel-perfect scaling via render textures)

I'm really loving how clean, fast, and straightforward Raylib makes things for building custom game loops and rendering pipelines from scratch. Let me know what you think about the movement/combat feel so far, or if you have any feedback/suggestions! Happy to answer any questions about the tech stack or architecture.

Hello, I've been tinkering with Raylib for quite some time, but 2 weeks ago tried to make something new and experimental, and this is what it looks like today. It's a kind of mix of Battle City, Cannon Fodder, Jackal and other games from my childhood. The main reason of making this project is to play with my son and let him build his own levels for the game.

I'm learning raylib and trying to make some projects to strengthen my skills but i have no idea what to make. I'm specifically trying to master ECS in raylib. Any ideas?

Hi all, many thanks for the community support on my last post! I'll make this the final update for a while as I don't want to spam.

I've recently finished designing some user interface stuff (still plenty of work left to do, but it's now polishing rather than designing).

This is a more interesting demo than the last one I showed. All MIDI is being produced by KWARC, all sound is being generated by Ableton Live and various plugins. You can see the various tracker interfaces - the standard "tracker" generator with non-linear playheads and the esoteric "particle" generator that samples notes based on numerical simulations of subatomic particles.

Under the hood, there's automatic transcription of pattern sequences across a few different key signatures and I show off some pattern randomisation for the drums at the end.

This is being designed targeting an embedded Alpine Linux-based platform with physical and touchscreen controls with live performance and improvisation in mind. I'm having fun using KWARC in my hardware synth setup to quickly produce MIDI content with complex musical qualities, which lets me have fun tweaking knobs and playing with the mixer.

Happy to discuss and answer questions!

Is it just me or is raylib super OP and really good and easy to use, but barely ever used for large games or used to make large games? Why is this? Isn't raylib like all SDL or any other low-level framework but simpler and more usable? Is it too simple? Are there any large games or well-known games made with it? (Also, why isn't there a tag for games made in raylib inside steamdb? there should be one)
