Such a good tutorial..... Literally I have spent 10 hrs and watched a totally of 30 tutorials to get my dang door to open.... NONE OF THEM WORKED UNTIL I FOUND YOURS! My only problem is my animations are not showing up the door will open knocking my player out of the way but the doors in the exact same spot XD atleast now I can walk into my town :D So Ill have to figure out why my animations aren't working!

[@II-or8pw]

Thank you, learning unity right now and this helped a lot for a group project i have in school, really easy to follow and very clear to understand, thank you !

[@SpeedTutor]

I'm really glad you liked it! :)

[@h38-m9e]

Great method. However, one slight issue is that you can spam click your open/close key to trigger the animation. I fixed this by adding two animation states; open and closed- both obviously having an idle position for the closed and opened door. Then, I check to see if the door is in one of these animation states before opening/closing the door: if (yourAnimator.GetCurrentAnimatorStateInfo(0).IsName("opened") || yourAnimator.GetCurrentAnimatorStateInfo(0).IsName("closed") { //Open & Close your door } Hope this helps!

[@SpeedTutor]

That's great to hear! I did make an update to my "Door Interaction Kit" which has an example of how to stop being able to spam the animations, I think I even updated this in the recent door videos too! :) Thanks for the suggestion though!

[@dragonanimations0748]

@@SpeedTutor would i be able use this tutorial multiple times in one setting? if so would I have to make a new script per object even if they have the same animation. For example, I'm currently working on making a target shooter game and have been struggling with making the collapse animation play when the target is shot by a raycast. I've been able to get this code for one target, though it gets a little finicky at times, I've been having trouble applying the code to multiple targets. Any suggestions?

[@EnriqueIMMontemar]

it's not necessary to make 2 animations for the door, you can just copy the open animation in the animator and put the speed as -1

Great advice, I realised this in my more recent examples of opening doors. I do show that in my other animation style tutorials, thanks for sharing though! :)

@@SpeedTutor Thank you so much. We will introduce you in the credits of the end roll of the game.

[@FoxGAMING-NTF]

I can't seem to be able to get this to work for me, the crosshair will never change, either. I tried getting your Free Door Interaction Asset on the Unity Asset Store, and it would work for the prefab doors, but not for what I'm trying to use it on/ for, which is a trash can door. It's supposed to be so that you can look at the door, and then left click on it to open / close the door / lid. Edit / Update: Ok, so I'm just dumb, all I needed to do was make the Box Collider a bit bigger. Another Edit: Ok, Maybe not, I can't get it to work again anymore. Another (Hopefully, I guess, Final,), Update: Ok, so I think it actually is that. It (the Box Collider,), has to be the height of my player or something, in order for it to detect it. I guess, in this case, is there a way to make it be so that I don't have to make the Box Collider so big that it will obstruct other collisions? The trash can in question (and all of them, probably, for that matter,), have another box collider for being able to drag the trash can around, and this Box Collider, with the fact that it has to be so big, means that it collides with the box collider for this. Plus, it makes the spot you have to look at the trash can door / lid for very unrealistic / inaccurate / big.

[@SpeedTutor]

I'm not really sure what to suggest because I've never had to make the box collider bigger than the player, you can normally do it on a tiny little object. Are you using it in a first person style?

[@FoxGAMING-NTF]

@@SpeedTutor Yes, I'm trying to make / use a full-body FPS Setup. I'm using FirstPersonAIO (First Person All-in-One). It seems, that the collider has to be the height of the player, or at least, up to the height of the player camera.

[@FoxGAMING-NTF]

@@SpeedTutor I'm also trying to figure out how to make the player character's head move with the camera. Currently, I have the player camera as a child of the DEF-head bone, and the head bone has a script attached to it to make it follow the camera, but it makes the camera jitter, shake, and wobble, quite a lot. And, it seems as if the camera moves at a different, faster speed than the head, and the head can twist too far. It only makes the head move up and down, since because I think it's since I'm using the FirstPersonAIO System, and I have the player character mesh as a child of the FPSAIO Controller, so it rotates the body left and right when you look left and right. But still, there needs to be a limit to the angle of rotation that the head can make, and I need to figure out a way to make the camera and head move at the same speed, and look at the same angle.

[@ericmiyan3466]

i dont get any error but the animations just wont play even when i set open door to default the door doesnt move

Hi, where did u get ur FPSController and MainCamera game objects from? I have followed the tutorial closely but mine doesnt work. (Crosshair unresponsive, animation and door not interactable) I got my FPS controller from the unity asset store but it looks different from yours. I suspect that I have attached my scripts to the wrong objects.

It's the Unity standard assets but controllers are built slightly different depending on what you've got hold of :)

[@ax4mineshaft844]

@@SpeedTutor Would the FPSController in this video be the same as the one in ur FPS controller tutorial 2 months ago?

[@bmpproductions]

This probably has a simple answer, but... I really need to know how to get multiple doors and objects to have their respective animations work when clicked on. Example: I have multiple working doors but I have another object with cabinet doors that have different animations. Would that be able to be accessed through the DoorController script or will I need to make a separate one for that. If you can, explain what I could do here, please and thank you.

[@SpeedTutor]

I can't fully remember how I coded this but the best way is to create one script which controls playing animations or use "Events" so you can play specific animations on objects with one script. You can check out my tutorial on events, this means all objects have the same script but like UI buttons, have events where you can do whatever action you want :)

[@saihou1280]

what i did was use the same raycast code but change the controller

That didn't work for me but I've found a fix, if anyone else is having this question in 2023 - Instead of having a single raycastedObj variable, change it to an array or a list to store references to multiple doors. e.g. private List raycastedDoors = new List(); and then update the logic in the "Update" function to handle multiple doors according to that change. Don't forget to give your new animated doors/windows/curtains interactable tag and switch Layer to Interact.

Maybe you're missing the tag? Collider? Anything like that?

[@muhammadabdullahkhan5]

Hi, Can you help me a little bit how do I set my tag to interactive object and how to set layer to raycast ?? BTW Thanks for tutorial

[@SpeedTutor]

Just at the top of the inspector, there are tags and layers. You can click the drop down and choose to add a new tag or layer. Then in the boxes which appear, add a new one in a blank area! :)

[@awsumturtle]

It worked but i'm having the problem that when you spam click the door it does some weird things. I've tried the fix from below but since my code is a bit different it's not working.

[@SpeedTutor]

In my more recent door tutorials and my Door interaction kit, I show you how to sort that issue! :)

[@awsumturtle]

@@SpeedTutor I figured it out by myself, I dont know if its good code but i decided to add an ienumerator that waits a second before a bool is set to true that controls whether you can open/close the door.

[@SpeedTutor]

I think that's what I did, you can check out my free kit on the store and see if it's the same! :)

[@Kraizelle]

For some reason, i am getting the following error: Tag: InteractiveObject is not defined. UnityEngine.Component:CompareTag(string) I've tried everything but I can't make it work

I got a problem with the raycast, the error says: Assets\MyDoorRaycast.cs(15,30): error CS0246: The type or namespace name 'Image' could not be found (are you missing a using directive or an assembly reference?). Then i added a canvas with a child named Image that is the crosshair, and still doesn't works. I don't know if it's because I didn't got my FPS of your channel of something. Please help me

[@SpeedTutor]

Did you add "Using UnityEngine.UI" to to the top?

[@chrestycs]

@@SpeedTutor what's that?

A namespace to access all the UI scripting references, you'll need :)

[@StigDesign]

Awesome :D i wonder how you could make door like they are in RainBowSix3 rave shield where you could use mouse wheel to slowly open/close door hehe :D what i think might be a way not efficent but, is some how each rotation angel and use inc& dec the rotation angel as long as it is within threshold also local rotation :D

[@SpeedTutor]

Exactly! That's why I imagine you'd do it! Depending on your input of the mouse wheel, you'd increase the angle by 10 degrees each time! :)

Has anyone tried to set their raycast lower than 5? For some reason it doesnt do anything even when set at 1 so it just feels like ive got really long arms

[@SpeedTutor]

Sometimes the player collider might get in the way of your raycast if you're not careful, sometimes you may have to set your player collider to "Ignore raycast" :)

[@littledarkage1-964]

I instantiate multiple doors in my project, but instead of the door prefab I click, or any door in the scene, only one specific door prefab (the first one to be instantiated) animates. Do you have any idea what might cause this issue? Thanks in advance.

[@littledarkage1-964]

In this part, if I don't put one of the comment lines, it gives null reference error. If I put one of these, it animates the first prefab instantiated like I mentioned previously. Not sure what to do at this point. if (Input.GetKeyDown(openDoorKey)) { //raycastedObj = GameObject.FindWithTag("doorTag").GetComponent(); //raycastedObj = GameObject.Find("doorNew(Clone)").GetComponent(); raycastedObj.PlayAnimation(); }

[@SpeedTutor]

I'm not really sure what to suggest to you. :( Could you untie those prefabs?

[@littledarkage1-964]

Not sure what you mean exactly. Thanks for the amazing tutorials by the way.

[@SpeedTutor]

As in, unpack the prefab when you start? (And) Thanks very much, I'm glad it was helpful to you! :)

[@littledarkage1-964]

@@SpeedTutor The problem was about my prefab structure. The raycast hit wasn't seeing my prefab's box collider because of some scaling issue in my code, box colliders were occuring somewhere irrelevant. In my previous comment, the code's comment lines caused referencing the first occuring door prefab in the scene for the raycasted object, therefore only that door was being animated no matter which door was clicked. I just wanted to explain for anyone who might have similar issues, and wanted to thank you again, for your tutorials and your willingness to help everyone in the comments.

Yes, you'd want an intermediate script which controls what types of doors you can choose from and depending on the tag or type you find, you can do some functionality! :)

You could create a little cooldown timer, using a co-routine each time you click it. Set a boolean true when it's clicked, set it to false in the cooldown and check that boolean in the code when you click or play the animation! :)

@@SpeedTutor I finally got around doing it and you were right, thanks so much! Just a note for anyone who tries to do this with a 3rd person character in the future, the only difference is that you might have to make your ray length a bit higher, since it's the camera, not the player character that interacts with the object, and camera is obviously further away if you are using a 3rd person view. I had to set ray length to 9 in order to make it work but it really depends on your setup.
