Tutorial: RayCast3D Projectiles in Godot 4

In this Godot 4 tutorial we are building RayCast3D based projectiles, as well as tackling some common use cases such as:
- Firing them in response to input events.
- Cleaning them up with the Timer node.
- Attaching to objects, so they can get embeded in things like enemies and moving platforms.

🤖 This tutorial is using Godot 4.2.2 stable.

I really appreciate that you take the time to explain each of the features of the gdscripts, the nodes and the game engine environment. It is very helpful for a beginner, many tutorials gloss over the details and I end up not understanding what any of the code actually means. Thank you for your work in creating this amazing resource.

You're tutorials are probably the best out there for godot. VERY happy to see your triumphant return

[cyb-mg]

Some of the best tutorials out there. Thank you.

So many useful pieces throughout this. I don't have any need for a projectile system in my game but I can already see how to apply a lot of this to certain enemy behaviours.

Also, 4:58 I could not tell you how many times that has stalled my progress and left me scratching my head as to why things are moving "backwards".

This is really polished! Great job, Bram. It was a pleasure to have a chance to meet in person, albeit briefly. I'm looking forward to seeing more from you!

[LucyLavend]

Lovely presentation, the models for the environment and character looks really cute! Also I didn't know about the "Add type hints" editor setting, thanks :)

[davidj]

High quality! Great to see that your back!

[Goobl]

I LITARALLY JUST NEEDED THIS THANK YOU

[EmDrive_]

Idk what it is about Godot, maybe it's the python like scripting and the modularity, but man, it's just so intuitive. Great tutorial!

[humbleraider]

Wow, this tutorial is very clear and it's working great! Thank you very much.

[ktna]

This is just unreasonably good content, everything is explained so well.

[GeneralChrisGaming]

Would be cool to see all the projectiles fall off the object when it get deleted like in minecraft and arrows. Great tutorial always a pleasure to watch and learn from ya

[MrigankaS]

This is an amazing tutorial! Thank you!

[AlexanderAgu]

I’m currently creating my first game Wich is a third person shooter and your detailed explanations are top tier 🔥🔥once I start my devlogs my first game will be credited to you😂

[ThunderPlayStudios]

Always good to see your video. that's very informative 🗣

[RuslanKhamidoullin]

Excellent explanation. Always move this way.

Hello, your tutorial is wonderful, I already did a projectile system, but I learned a thing or two. I wish I had it when I started as this is pretty complicated.

One thing: the forward vector is already part of the basis, so you can just do global_basis.z.

The RemoteTransform is interesting, but I find it easier to simply attach the projectile as a child of the collider.

Please make a video on how to do this type of natural voxel artstyle. It's amazing!

[jakeklassen]

Great content. Also this scene asethetic is so charming and pixelated. Do you cover achieving that look in any tutorial content? Really cool.

If you can't connect the timeout function to the cleanup function, save the script first ;)
