Player Interact with Objects & Resource Signal Bus Tutorial - Godot 4.2

Detailed tutorial showing how to let a player press a key to interact with interactable objects such as a Shop, a Switch, or a Chest. For accessing player data, we can also use Resources with signals to serve as a signal bus for telling user interface nodes when the player is set or updated.

Sir, can you please make save, level and ability system to your Unity Platformer Crash Course? Your videos are very understandable and instructive than others. I would love to watch.

Hello again, I finished the first part of the tutorial (up to 27:30) and noticed that once you enter the interaction area and toggle the fan on, you can continue to toggle the fan even after leaving the interaction area.
The array nearby_interactables is cleared once I leave the area, it's size reduces to 0, but for some reason hitting the action key still toggles the animation.

Edit: He talks about this at around 40:10.

Could you make a tutorial for a fighting game in godot 4.2? I'm sure it will make a lot of people happy and you'll get a lot of views too.

Would it be possible to provide the Pre-Tutorial Project in a version in which it can be started without a Vulkan capable GPU?
So that it is able to run in Compatability mode aswell?

Curious, once we press our interact button, how or where can we make the indicator above the object hide? And when we leave the area it resets so returning to area it will pop up again. If you got a min, I am stuck on getting ride of the dancing pineapple. ;) Great help and thank you

Could you make a tutorial for a fighting game? It would be really cool if you showed the implementation of the multiplayer mode.

i really liked you approach ! I'm still at a very early stage of my developement practice and i have a question ! It feels like your approach is very similar to the interface principle in c#. Is it as efficient in godot as it would be in unity since there is not real official way of doing interface in gdscript ? (yet hopefully) Thank you very much !!

[benjotest]

May i ask do you still use cyberghost?
