How to Add Interaction in Godot 4

[@mrjshzk]

I've been watching Godot tutorials for a while but this one is very interesting! I never thought about using an animation tree for a door!

[@malplex]

Just want to say that your tutorials are great, they helped me a lot to learn Godot, thank you

[@Keallan]

bro TYSM for these tutorials! i never found any tutorials that are as interesting as yours tbh

[@NekotoArts]

The King returns! Also really great resource! Some of this stuff they updated in Godot 4 confused me haha, but it made sense after watching the video.

[@amegatron07]

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".

[@grzegorzpedrycz2630]

Awasome piece of knowlage !

[@superandreluizduarte]

A tutorial video that doesn't FEEL like a tutorial is my thing, great video!

[@amirosman8797]

This is amazing, great video man and welcome back, I hope you are planning on making more tutorials

[@DuhKoreGames]

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!

Hey Nagi! I like your videos. Keep it up!

[@vishnuviswanathan4763]

welcome back dude

[@clashofclans9783]

Nagi when the player collides with a physical object, the physical object penetrates the wall or the ground. How can I fix this?

[@NagiDev]

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.

[@clashofclans9783]

amazing video mr nagi keep em coming

[@yc5882]

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?

[@DuhKoreGames]

do you know how to implement a mouse click into this? ive tried to do replace E with LMB or RMB and it shows up invisible

[@Thewallrunner749]

Could you make a tutorial for a pick up and drop system similar to granny ?

[@Meraba_Abi]

Amazing work. Keep it up.

[@KelpDev]

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.

[@jamesrivettcarnac]

This is really well done

[@nettorb_]

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()

[@NagiDev]

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!

[@nettorb_]

@@NagiDev No problem, thank you so much! that really helps! :D

[@mimadm4832]

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

[@NagiDev]

can you share the error Godot shows on crashing?

[@mimadm4832]

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

[@BreezyDefrag]

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?

[@NagiDev]

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?

[@BreezyDefrag]

@@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.

[@NagiDev]

@@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.

mine isnt showing the prompt message, it just says not then [E]

[@NagiDev]

Hi! can you please share in detail the issues you're facing?

[@damnthishandleistaken]

What if I want to open the door by directly interacting with it?

[@NagiDev]

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.

[@damnthishandleistaken]

@@NagiDev Oh, that seems pretty obvious haha I'm so dumb. Thank you so much for the quick reply!

[@NagiDev]

@damnthishandleistaken calling people dumb is not allowed (especially when that person is yourself). You're still learning, it's okay.

[@JiKayPh]

Can you give me more videos explaining the buttons in detail in Godot?

[@NagiDev]

What parts would you like to know more about?

[@JiKayPh]

@@NagiDev You can teach the necessary knowledge or use in a platform-style game

[@NagiDev]

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 KZbin 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!

[@JiKayPh]

@@NagiDev Thanks you so much ❤

[@tigergamespl2713]

for some reason my raycast doesn't detect like at all

[@NagiDev]

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?

[@tigergamespl2713]

my bad, i guess i have to make it a child node of the camera so it would go with my screen since i guess that's how I set up my code

[@Thewanderer-ym9xs]

If I only wanted to add the crosshair to the UI part, do I have to add script to the control node?

If you only want the basic crosshair, you don't really have to add any script.

Sure. Can you share which parts were hard to understand?

@@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 🥲🙏

[@NagiDev]

@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.

help: Invalid access to property or key 'prompt_message' on a base object of type 'CSGBox3D'.

[@NagiDev]

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.

[@NagiDev]

Also, did you skip the condition check in the code? Please check if you skipped some part of the code as that may explain this error.

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?

[@NagiDev]

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.

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.
