Raycast Weapons in Godot - Make an FPS in Godot Part 2

In this video I will show you how to create a Raycast Weapon system in Godot
Part 1: • FPS Character Controll...
Source Code for Part 1: github.com/codewithtom/godot-...
Source Code for this tutorial: github.com/codewithtom/godot-...
This video covers creating a raycast weapon system in our FPS game, as well as inheriting from the base weapon to allow you to make modifications for new weapons and weapon types. We also add some simple UI to display the current ammo count and reloading status.
In this series of FPS Godot tutorials I will teach you how to make your very own FPS in Godot. Subscribe to stay up to date!

Great Tutorials, the best ones I can find on KZbin.

[@CodeWithTom]

Thank you so much!

[@sergeiorlov5096]

I know that I'm a bit late with my reply, but heck - it might help someone reading this in the future. I LOVE Tom's tutorials, but you must know that theres quite a lot of quality tutors beside Tom. My personal favourites: "Game Development Center" - aimed at Diablo style rpg's and networking "Garbaj" - Just like Tom, he's mainly into FPS 'Rungeon" - a fairly new channel, but damn that guy is a gem. THE best platformer tutorials I've seen so far! "Heartbeast" - zelda-like (or ratherHyper light Drifter- like) arpg tutorials, and much more! "KidsCanCode" - This guy is a Wikipedia of Godot. Quality stuff! And these guys are just my top pics- I'm sure there's even more quality content out there. Hope that these references will help someone, as these tutors (Including Tom, obviously) helped me )

Amazing tutorial, your content is simply great! I have been messing arroung with Godot and you have helped me a lot to work my way out. Thanks for the great videos!

[@KyleHarmieson]

The class/inheritance solution to multiple weapons has totally revolutionised the way I design weapons in my game. Thank you so, so much for explaining how to define and inherit classes! I've even gone a step further and inherited from weapon to create three specialised classes: raycast_weapon, projectile_weapon and melee_weapon!

[@CodeWithTom]

Glad I could help! That sounds like a perfect solution to varying weapon types.😁

[@KyleHarmieson]

@@CodeWithTom It's working beautifully! It also makes it much easier to organise the weapons in my project, and to refer to them and use their stats in the game. This "template" approach is perfect for my game's modular weapon system. Thanks again for the idea! :D

que bueno el mejor que vi 3d asta a hora muchas gracias!!

[@KellenChase]

wow, so appreciated. this is a great tutorial series. learning a lot, and excited to have a character that can already run around and kill enemies. thank you! got a question that I will try and research if I don't see it covered. Ill edit this comment when I find an answer... when my mouse is not in the screen area when starting, any click, clicks me out of the game again as if Id hit the escape key. is there a way to grab the mouse cursor, center it, then run the capture process? it's not an issue if I hit play and then get my mouse into the window area before it's fully loaded. oooh... you pulled a sneaky around 13:50 ... added the class_name without telling us. when we create shotgun.gd, gives a little error when trying to extend without the class_name in Weapon.gd ... dangit... should have just played another 5 seconds of the video... ;) alright, so I added the ready process that was put in shotgun.gd to the ready process in weapon.gd (so the shotgun can inherit the generic fire_range, and that can be brought into all future weapons as well). I feel like one change that I am going to work on as well is that the reload should be able to happen right after the last shot... at current, it is waiting for a timeout to allow another shot, and then that shot turns into a reload... really enjoying this. thanks again! What I would like to see next... (don't know if its in the playlist from where I am sitting now) is an inventory system, weapon selection, etc.... I like the idea of an FPS RPG, and I think that those two combinations for a game covers so many concepts and ideas of game design, that it could be a great teaching series in itself.

Thanks! Projectile bullets are definitely on my todo list.

[@specialeddgames5668]

Could you show us in the next video how to make it to where we can see where the bullet goes and have it shoot out of a gun

[@CodeWithTom]

I'll add it to the list for sure. I'd like to add a decal system at some point for bullet holes etc

[@retrocademedia-announcements]

At 25:04 you can just use onready before current_ammo rather than using the ready function

[@Buli0n]

Please show us how to make enviromental hazards such as water or lava or fire or smoke or fog, scripts of things that appear and dissapear and physics of ropes! 🙏

[@CodeWithTom]

Great suggestion! I'll add it to the list

[@LockStockNBarrel]

Is yield() a non blocking wait? What happens to other code in the same function during that time? Does it actually block further code execution but only for the _process() function which runs on every frame? What if I want to do other things in the _process() function in the mean time?

[@CodeWithTom]

Good question. Yields are complicated to explain in a single response. But they are effectively a way of initiating coroutines, freezing the current state of execution and resuming once they receive a completed signal. You can read more here: docs.godotengine.org/en/3.0/getting_started/scripting/gdscript/gdscript_basics.html#coroutines-with-yield

[@Alternalo]

How can i make a visual feedback on the point of impact?

[@JacobKinsley]

Is it better to create a raycast in code or to create a raycasts object in the scene and just hiding/unhiding? I'm assuming in the scene because then you don't have to create and delete it every time, but it only works if it's always from the center of the camera to the middle of the screen

[@matrixchronic8542]

Is there a way to show the Bullets coming out the gun

[@geckopg3d394]

For those of you who want to reload when your ammo is at 0, simply put: if current_ammo < 1 and not reloading: reload() in the func _process(delta) function so you don't have to press r or shoot

[@RexieRacer]

For anyone wondering, at the time im at in the video you dont need the export infront of the var (var fire_rate etc.) it made my code not work so i wanted to put this out so you know the problem.

[@alialramadhan4748]

hello mister Tom i hope you are having a great day, I appreciate your tutorial. I need help with something though if I want to have no reload weapon can i just skip the steps of 8:00 - 12:00 min mark?

[@CodeWithTom]

Hi Ali, absolutely! If you don't want reloading feel free to skip that entirely.

[@jackv7614]

how would you switch between two different weapons? when I try to change the script while it's running it crashes

[@hobbesthebrainslug12]

Well here I am running into another problem. I'm at the point where we're coding the raycast to delete/kill enemies. I have everything set up as you put it. But nothing happens when I 'fire' on an enemy. It just prints 'fired weapon'. The enemy doesn't disappear. With 'Visible collision shapes' turned on I can see that the game knows something is there when I mouse over it. But wont do anything when I fire.

[@MrTobbeman22]

Sounds like you missed "collider.queue_free()"

[@Jaydenbb5]

[@rishianands8472]

Thanks a lot TOM...

[@CodeWithTom]

You're very welcome Rishi!

[@vickylance]

@26:16 I think the solution to directly access the label and change it every process frame is not a good practise in terms of both performance and single responsibility principle. The weapon class should not handle the UI elements. Instead what I think is that it should simply emit a signal and then the UI node should have a script that should capture that signal and then act upon it

[@CodeWithTom]

Very good recommendation, you're absolutely right. I will cover signals in a future video.

[@sage1582]

[@RaiderJake]

How would I set it to an automatic fire, like just holding the left click button? Great tutorials thank you.

[@Dogman_35]

Remove the "just" is is_action_just_pressed. The "just" means it only checks the first time you click, and if you remove it then it will constantly fire every time the firerate timer is up as long as you're holding down the button.

Hello Tom, thank you for your videos. Why function check collision does not work on my Godot? When I hit, it does not detect the enemy.

Hi Kendra, can you make sure you're calling the check_collision() function. I would start by calling print('check_collision is being called') as the first line of that function to see if it is indeed being called or not.
