You should be able to leave the interact variable null if you wanted, it was set up like that to visualize that an interact script should automatically create its own instance of an InteractEvent on creation. the GetInteractEvent check/creation is just a failsafe to guarantee an interact script has an event when it needs to be used.

Not really. This guy just talks kind of fast and explains some things that aren't relevant to the subject (like layer masks)--there's no need to go into bitwise operations on a video about event delegates. He's good and obviously knows what he's talking about, but there are better tutorials out there and you shouldn't assume you're out of your depth because of the way someone teaches.

It just allows you to be able create > set > and get a reference to the interact event without making the interact event a public variable (which would display it in the inspector). It’s not strictly necessary its just for cleanliness - and also makes the interact event created inside the Interact mono behavior un-editable, since with the GetInteractEvent you can only *get* the interact event, you cannot *set* it from outside the script.

In your example I would rather have the player both call the interaction with the chest and also start its own animation, this also helps with timing if you need your player to scoot over to the chest before starting an animation you could handle that first, then activate the player opening animation along with calling interact at the same time.

Thanks for posting your fix. The Z value for UI positions is the depth away from the camera and negative values will put them ‘behind’ the camera (I guess a value of 0 will do this as well in orthographic, I didn’t know that). You can also use this to turn off elements you don’t want to see when there’s UI elements attached to 3D objects, I’ve used negative values for floating health bars on enemies that were behind the camera otherwise they will always draw even when the enemy isn’t on screen, for example.

@@JosephMask3D Thanks for the advice. I take note. I understand correctly, what Input.mousePosition.z = 0f? I debug (mousePosition) and yes, mousePosition.z = 0.00; This is rhetorical question =)

Addition: I catch one more problem. Problem next: When we click "mouse1" for clear Mouse.itemSlot, above another ItemPanel, the ItemPanel attached to our cursor. I fix this problem in ItemPanel added check only on Mouse0 in method OnPointerDown. Its look like this: if (Input.GetKeyDown(KeyCode.Mouse0)) _click = true; Based on this, I have folling quession. How to make "correct" organize InputSystem (not class, its idia in Architecture Project), that to make work to easier in the future? I`m noob in GameDev and I don`t know anything about creating the "correct" Architecture Project.

@@Ivan_Larsen Just for clarification, you are asking how to go about creating a Sort function for the inventory?

@@JosephMask3D Sorry for my english. I`m about something like this: Game Programming Patterns. To what extent I made the right decision to solve the problem and how convenient it will be to work with such code in the future. So that I don’t have to rewrite many lines of code in each script to implement control settings (hotkeys). If you don`t uderstand me, it`s not your problem, its my english) Sorry for waste your time.

You could create an OnPickup method that you call only on the item you are adding to your item list as you add it to the list, or could add a bool variable to the item (in the same way you would add a variable to any other class near the top under the class name) to check if its been activated already if you are trying to do something more complex

@@JosephMask3D thanks for the solutions! But how would I 'delete' an item? Like deactivate it when it is removed from the list.

@@Turdstrider Same idea, create an OnDrop method that’s called in the same code that deletes the item. If you are trying to remove a buff that was applied then loop through the players buffs and deactivate it. If the item spawned an object you will need to maintain a reference to that object (like adding a reference variable to the item that you set when you create the object) and delete it when the item is removed.

@@JosephMask3D Thanks for the quick and very insightful responses! I've actually just made an item that has a chance on shooting to fire a triple shot!

Yes it could I think. I would try making a chest UI that’s basically identical to the player inventory UI, just in a separate location on the screen, and store item lists in chest object scripts, when the player interacts with a chest the system grabs the list and uses that to populate the chest UI.

That sounds like it could work, I will try that. Thank you for a very quick reply :) Do you have a donation site like ko-fi or something similar? I would like to support you in some way to make more great content like this.@@JosephMask3D

⁠​⁠@@JosephMask3DThat sounds like it could work, I will try that. Thank you for a very quick reply!

@@JosephMask3D Just coming back to this and say that it worked great to make a secondary inventory system for a chest. Although it's a bit coupled and a bit tedious to make more than one, it worked great for just having one more. Thank you again. Is it possible to make a donation to support this and future videos?

@@MrTekui Glad to hear it worked! You might be able to use the Inventory script as double duty for both the Inventory and chest management since they will be so similar, and because you would usually want your inventory open as you use a chest, would just need to add a chest item list variable and update it with the currently selected chest, etc. I don't have any donations set up at the moment, but I really appreciate the thought.

That was a mistake, apologies. I updated it with an MIT license.

Thanks! @@JosephMask3D

Yes

Yes, I use the same idea for UI. Abstract classes cant appear in the inspector in Unity (without some heavy workarounds) because they aren't serialized, so you cant really drop a sprite into each individual item script like you can with a monobehaviour script, so grabbing a sprite from a Resources.Load directory is the easiest solution to tie a specific sprite to an item.

@@JosephMask3D Thanks for the the quick reply, I literally just got it done working. I have one more question though, with the type of items i'd like to introdcute it would really be handy if for each time i had a GetStacks() function just to know how many stacks i have of one specific item. Whats a good way to implement this? A dictionary to keep track? private Dictionary<Item, int> stacksDictionary = new Dictionary<Item, int>();

@@NightHawx231 A dictionary would work perfectly well since that is one of its primary purposes, you could use the items name string as the key and whenever you add an item to the player you could also check the dictionary with TryGetValue or ContainsKey, and if it exists, up the value (or decrease if dropping an item), or add the item to the dictionary if it doesn't exist. You could also just do a loop of your itemlist, checking its name each loop, and once its found return the value.

too bad youtube doesn't have a feature built into the player the make the video play faster...

So for the spawn location, is your inventory script attached to your player GameObject, meaning the transform that is moving around the level with the player character? The DropItem method uses the transform of the gameobject that the Inventory script is placed on to determine the position to drop the item, the part in the Instantiate call that has *[this.transform.position + new Vector3(0, 1.8f, 0]*, if its attached to another object it will spawn on whatever object the Inventory script is attached to. As for the reason its moving forever in the Y direction; Other than giving the Rigidbody some velocity when we spawn our object, the rest of the behavior is handled by the Rigidbody settings in Unity. Maybe check the gravity settings in your Project phsyics settings (the same place that has the triangle of physics interactions, at the top, It should be -9.81)? Or if you mean it falls through the floor maybe check that your root item pickup object (the main parent object for the prefab) can collide with the floor.

@@JosephMask3D alright, i fixed it

@@darkxplayzz I was working on a reply as I got this 😅. What was the problem if you don't mind me asking?

In a situation like that you could put a trigger collider on the player with a simple script to check for hits and call the pickup, then you could simplify the items down to one object.

@@JosephMask3D Is every new item a new script? And is it possible to somehow redo it for ScriptableObjects?

@@grandmax6223 It should be possible, the only info you need to get to the player is the name of the item and an amount. I don’t have much experience with ScriptableObjects though, so how to go about it using them I’m not sure.

@@JosephMask3D thx bro

It might be the directory string in Resources.Load being slightly incorrect, so it finds nothing and sets the image to null, leaving a white square.

@@JosephMask3D thank you very much.. it was my spacing in that very area.. thank u

Using a character controller, apologies

@@JosephMask3D OK, that is what I guessed you would be using.

BTW - your inventory tutorial was really nice, I've done several inventories (which I don't like) so nice to see different ways to do inventories.

@@322ss Thanks sir, really happy that people are getting good use from that video
