Only halfway through the video but I gotta say this tutorial is top notch my man. I was pulling my hair out trying to get this stuff working but you've clarified so many things for me.
Fantastic, Im watching while at work lol, Cant wait to get home and try this out. this is the reason I started this playlist, I had a 3d scene with a little dude wandering about, and looking online all the things for switches and signals were mental, wanting global scripts with lists of items for interaction and all kinds of crazy, This is exactly what I wanted, assign a button to an object, and have the button do stuff with the object..
Thanks for the video) Was going to make exactly such interactions, except that I was planning to have multiple "features" of objects, one of which would be "Interactable".
lol just found your channel like 2-3 days ago and was translating all the interaction stuff from godot 3 video to my 4.2 version XD could of just clicked on your channel to find this updated one smh either way im gonna watch it!
6:00 So I'm a bit confused about the mesh thing. I have models that I've made in blender but can't seem to use them as meshes for my static body. I've tried both gltf and glb files but when I import them they turn into 3DNodes and need inherited scenes
The easy method (which I used) is to open the gltf as an inherited scene, copy the mesh instance and paste it in your scene. An even easier solution is to just drag and drop the gltf in your scene.
Thank you for your tutorial. The textures in your videos look amazing. Do you create them yourself? Could you please share your workflow? How do you create the normal maps?
I'm glad you like them! Yes, I make them using Gimp and Krita. I hand paint all the textures and roughness map. For the normal maps, I draw the depth map (black is deep, white is shallow) and use the normal map filter in Krita to generate the final result.
Hi man!, everything works, but how to do if I want each button to have different sounds? Inheritance with signals breaks the system, and also how to run different streams in the audio player through the code? I'm not really strong in the code so please give me a hint!
5:58 i added the if collider is Interactable: line but now it wont show any prompt messages but it wont work without the line im on 4.2.2 is that why it no longer works?
can you please check if you set the raycast to ignore its parent. Because in most cases, it turns out that the raycast is constantly detecting the player's collisionShape, hence no prompt message. This setting might be different for 4.2.2, I'm not sure.
@nan0core25 Click on my name under the video to open my channel page, go to the videos tab, and you'll find the video "How to Code Player Health And Fall Damage in Godot 4" ruclips.net/video/X6gfjdXckpA/видео.htmlsi=eWXttE4eFze7ZGxp
CharacterBody vs RigidBody collisions tend to be that way. I haven't found an all-in-one fix for it, but depending on your game, you can make both the player and the object be either both rigidbodies or both characterbodies. You can also try the Jolt physics plugin but I'm not sure if it'll fix the issue.
Guide is good, I did find that the way you coded game overs did not have anything about setting the players health back to 100 after restarting right? So I went and tested it and unless I missed something that is the case(I probably missed something) soooo just in case you did not notice that then there you go haha, you respawn with essentially 0 hp
I have a quick question: If I wanted to make it so that you had to hold down an action key for a certain amount of time and have a progress bar on the screen that shows how far along the interaction is, how would I go about that?
Ok, so I am not a code guru or anything so I more just want to ask a question. Couldn't you just use an Enumerator Variable and then just add the code together? Is there a better reason why you use a Custom Class, rather than an Enumerator? And could someone explain what case states would be good for Custom Class VS. Enumerator?
To be frank, I'm not that bright myself, so maybe your approach would work just as well, if not better. Can you tell me more about the Enumerator approach a bit?
@@NagiDev Well with an Enumerator, and I am only touching surface level stuff here as I am still new to coding, but as I understand it you could create an Export Enumerator String Variable with a list of object names then use a Match script in it's own function that will automatically set variables, Names, and Interact buttons, etc. under each match case. Example match string (string Var): "String name": set variables to values. Then you just put that script onto an interactable object which will then show a dropdown in the Inspector. And when you change that Enum String to whatever the object is whether it's a "Button", "Switch", "Key", etc. and each can have it's own functions, calls, and variable sets. under each match state, so you could make the key update a key count var elsewhere, or use the toggle system. This is just a rough breakdown of how I would do this. That's in part why I am asking for some case states for why you would use a custom class over an enum. Hope that makes sense. ^^ Great video though.
@@BreezyDefrag well, that seems like an interesting way to handle it. However, from my past experiences (read, blunders) I try to steer away from putting all the code in one file. With the custom class, Interactable.gd can have all the code that would be common among all the interactive objects (prompt message, interaction logic, etc), while any logic specific to an interactive object can remain in its own script. Say, you want the button to play a press animation when interacted with. That code would only remain in the button's script. Hope you see my point of view. And yes, for a very basic use case, the enumerator method seems more easier to make, I'm just trying to make the system capable of being extended and customized.
You add an Area3D node to the door scene, and add a CollisionShape to the Area3D. Then attach the interactable.gd script to the Area3D, connect the signals to the door script. Boom! Profit.
I've shared all the necessary information about the button in this video. However, I can understand I didn't explain some of the Godot features thoroughly. You can watch my Godot 3 interaction video for some clarity or there's also plenty of videos on RUclips explaining Godot raycasts, area3D and signals (3 of the Godot features used in this video). But yeah, I plan on making much smaller videos in the future explaining these concepts for beginners. Cheers!
My game immediately crashes whenever I lok at any non-interactable object once I input the code from 7:23, the replacement of interact with collider.prompt_input. I got no clue on ohow to fix this, pls help also, the game just crashes whenever I press on any surface that isnt interactable
I have just decided to copy and paste your code to not bother with the headache, thabk you for the video and everything tho, once I open my pc I will tell the error message
this could mean either of these scenarios: - you haven't attached the script to the object - the raycast is detecting another object in the way - you skipped the condition checks in interactRay script - you probably misspelt the word somewhere Try to compare your code with the one in the description to see if you missed something?
You can put the object on a different collision layer and make it the raycast's mask to that layer. But I must warn you this way your raycast would be able to detect objects through walls.
If you don't want to rotate the raycast with the parent, you can set it as top level in the inspector, and then set it's position the same as the parent in the physics process function.
@@NagiDev thank you! I fixed it by myself yesterday, turns out my Raycast3D was actually working, it was just inside Area3D and aftwr moving it's origin a little bit away, everything got fixed
Very nice video, the animations a pretty cool :D Btw, when you set in the code to show what button to press, how can I make it show the mouse buttons like LMB or RMB? The code shows any other button, but the mouse ones it onlu shows "[]" This is the code i'm referring to: action.as_text_physical_keycode()
Heyo! So sorry for the late reply, but I found the solution! You should update the code in Interactable.gd like so: if action is InputEventKey: key_name = action.as_text_physical_keycode() break elif action is InputEventMouseButton: key_name = action.as_text() Hope this helps! Also, I'll push this code to the github repo. Thanks for the question!
Your raycast is detecting a CSGBox and trying to get the prompt_message property from it. Enable "show collision shapes" from the debug menu and check if the raycast is detecting another object in the way.
So im getting an error after typing if collider is interactable: Prompt.text = collider.prompt_message Its rhe if statements thats not working its giving me a couldnt not parse global class error
I mentioned it in another reply, but basically you add an Area3D node to the door scene, add a CollisionShape to it, add the interactable script to the area, and finally connect the signals like in the video.
To make the button invisible after interaction you can call hide() or $Button.hide() at the end of the _on_interacted() function that is triggered by the interacted signal. However the button would still be interactive even after being invisible. To prevent that, you can simply call queue_free() instead of hide() to delete the button after interaction; or you can create a variable to store whether the object is interactive or not and set it to false on interaction.
You made a causality dilemma because where do keys come from? And if you need a key to open a chest then where do you get the key to open a locked door? 🤯
Enable debug collision shapes from the debug menu and check if the ray cast may be detecting the player body itself. Or maybe you've set the collision layer of the raycast/collision object to some other value?
hey bro, can you make a graph edit and graph node tutorial, because I have an idea to make a game engine with godot with visual script as the script component.
This could be due to a few reasons: - you might've forgotten to define it in the interactable.gd script - maybe you named the signal differently in the script - maybe the script if not attached to the node - maybe you haven't saved the script yet, so the signal is not showing up in the inspector Please let me know if I can help, I'd be happy to do so
bro i wanna say it still feels kinda with all of this much and stuff in scene can u please make a simplified vedio for this again just implementing these systems simple scene altho it seems really goodd for future proof but as a beginner its hard pleaseeeeeee make easy and simplified one 🥲🙏🙏🙏🙏
@@NagiDev i wont say the whole vedio but for me the whole part for adding functinallity to button were difficult cuse according to me there was so much going on i could wrap my head around most of the things thats why i need a simplified verison and yeaaa overallllll great vedioooooo will ceratinly help me in future also can u make a simplified version for pickables stuff like torch will be gratefull for that 🥲🙏
@quiet5445 ah got it. So the thing is, you can define custom signals in a script which shows up in the node tab (beside the inspector) when you have the node with that script selected. In this video I created a custom signal "interacted" and connected it through the node tab to various functions in other scripts. So for example, button (Interactable.gd) -> interacted signal -> do_something() (function) Basically when the interactRay interacts with an Interactable node, the node emits the interacted signal, this signal can be connected to any number of functions in any script. So, when the interacted signal is emitted by that node, all the connected functions are called, and we can put the code we want to run inside these functions like we did in the video. I hope this helps you understand what's going on in the interaction system. If you still have doubts, feel free to contact me over at Discord @nagidev. Also, I would suggest you to learn more about Godot signals since they are really powerful for all sorts of things.
@@NagiDev thanku very much im just starting on this 3d project and your tutorial be of so much of help as there arent much tutorial on godot 4 on top of that you might not find what youre looking for altho interaction isnt that specific but still there isnt any vedio on youtube other than u that actually helped plus your the only one that replies tbh since getting replies from youtube channels nowdays is next to impossible until unless you comment on a recent vedio surely i would follow u on discord

To make the button invisible after interaction you can call hide() or $Button.hide() at the end of the _on_interacted() function that is triggered by the interacted signal.
However the button would still be interactive even after being invisible. To prevent that, you can simply call queue_free() instead of hide() to delete the button after interaction; or you can create a variable to store whether the object is interactive or not and set it to false on interaction.

@@NagiDev thanku very much im just starting on this 3d project and your tutorial be of so much of help as there arent much tutorial on godot 4 on top of that you might not find what youre looking for altho interaction isnt that specific but still there isnt any vedio on youtube other than u that actually helped plus your the only one that replies tbh since getting replies from youtube channels nowdays is next to impossible until unless you comment on a recent vedio surely i would follow u on discord
Hi bro, your videos are really cool, I can see how much you put into each of them. I would like to ask you about shapecast nodes, what get_collider index does ask for? I really need help😢
