[@mindonwarp]

As simple as I needed it. Thank you! For all of you looking for a way to play the animation only once and go back to the initial state: just go to the animation editor UI ("Animator" tab), right click on your triggered animation node and choose "Make transition". An arrow coming out of the node will show up. Just pull this arrow onto your initial/idle state node and that should do it (did for me).

but after activating the animation once, i cant do it after that.. could this be solved?

Zuchini DE sorry for late reply but in update use the following code If(Input.GetKeyUp("1")) ( anim.play("name of animation") = false ) If not use this one If(Input.GetKeyUp("1")) ( anim.stop("name of animation") ) Or use this one by making another animation which has nothing transformed and write If(Input.GetKeyUp("1")) ( anim.play("name of animation1") )

[@tomcruz8615]

Quick question. What would you use to trigger two animations with the same key? (Sounds like a dumb question but i'm a unity newb so whatever).

[@kaldogorath]

I'm not sure if you can play two animations from the same controller (anim here) at the same time. Either way, you would simply call another thing in the if statement where the anim.Play(); is called already. so it would read like anim.Play("clip1"); anim.Play("clip2"); That is, if you can play two from the same one. If not, you'll need two animator controllers and would call anim1.Play and anim2.Play back to back in the if statement.

[@tomcruz8615]

Nick Miller ohhh I'll try both of those out. Thank you for that

[@Nikoplays0910]

Thanks, now I can play the orange justice animation

[@nibernator]

For some reason I am getting an error: Invalid Layer Index '-1' I did everything exactly like the video, no dice...

[@CubicBrain]

Hi, please double check your namings/case-sensitiviness for the animations etc. could you post your code?

[@nibernator]

using System.Collections; using System.Collections.Generic; using UnityEngine; // THIS SCRIPT NOT WORKING public class animController : MonoBehaviour { public Animator anim; // Use this for initialization void Start () { anim = GetComponent(); // caches controller at start. } // Update is called once per frame void Update () { // string reference //check for key press if (Input.GetKeyDown("1")) { print("Key Down"); // To test if input responds to key. anim.Play("cubeAnimation"); // Plays the animation asset named cubeAnimation. } } }

[@nibernator]

These are what the errors say, "Animator.GotoState: State could not be found UnityEngine.Animator:Play(String) animController:Update() (at Assets/animController.cs:22)" The other error: "Invalid Layer Index '-1' UnityEngine.Animator:Play(String) animController:Update() (at Assets/animController.cs:22)" Thanks for your time!

[@CubicBrain]

I'm thinking it could be one of two things. It might be that the animator hasn't been added to the field in the inspector, or that the naming of the specific animation state (the animation you want to play back) isn't correct?

[@karanveermultani6594]

I know this comment was a year back but I found out what was wrong. There is an extra if statement in the update. Remove the one that plays "New cube animation" and you won't get the error anymore. The code in the comments has this, so please do mind changing it.

hey i dont know if you can help me but whenever i press the button to do the animation it stays frozen at the end of the animation and dosent transform back to its orignal state and says Katana AnimationEvent has no function specified

[@CubicBrain]

Hi Jasiel, You can add a transition to an idle state in the animation, or make the animation loop. Animations are a bit like video playback, and will just stop at the last frame.

[@emilyallen7912]

It won’t let me add a new state when I right click it just says add behavior

[@haru_ne_]

I wanted to know how to use Trigger parameters but I figure it out anyway. Thanks.

[@ruler1559]

say if I want to get back to the other animation, how do I do it?

[@CubicBrain]

If you just want it to go back automatically, right click the animation node that you trigger, and select make transition. then click back on the first animation node.

[@CubicBrain]

Hi Zeyad, You have to set up a trigger-collider on the trigger (gameobject) of your choosing. then on that object in a script use the "OnTriggerEnter" function like: void OnTriggerEnter(Collider other) { //code you want to execute } as soon as another gameobject with a colliger enters your trigger collider, it should execute the code.

[@CubicBrain]

The simplest solution would be to set a transition within the animator, to either the exit state, or a new idle state.

Just a quick question... How do I make the animation play only once?

[@CubicBrain]

Hi, You can set an "Exit" on the animation. You have your animation that you start with. Normally that it would then just sit there stuck in that animation. However if you set a transition to exit or an empty animation it will only play once.

[@FoxGAMING-NTF]

CubicBrain Thanks!

[@FoxGAMING-NTF]

CubicBrain Also, I need help with something else. . . So, I'm making a horror game. There is a fridge that will contain clues. It has double doors. I want to add the animation to it. How would I make it so that when I am close to the doors (Each door has a box collider, and if the door rotates, the box collider rotates with it) another animation plays (aka the closing)? How could I switch the activator to be a left click (GetMouseDown;), right? And how could I make it so that When I left click, it Opens, and stays open, even when I walk away, and when I walk back into the box collider, how could I make it so that I have to click again to close it? Sorry for all of the questions, I hope they make sense and you can help me figure them out. I'm just desperate to get this done, and nothing else has helped...

I was hoping you may be able to help. I followed your tut but tailored one or 2 bits but I'm getting this error - MissingComponentException: There is no 'Animator' attached to the "Player" game object, but a script is trying to access it. You probably need to add a Animator to the game object "Player". Or your script needs to check if the component is attached before using it. - I have attached the script to both the player and the object but it still throwing back this error. Do you know what I could be doing wrong?

I want to make it so that you can press the button multiple times a knob moves further like one step at a time. Is it posible to do it with only one animation, or do i need one for each step of the knob? pls reply

[@CubicBrain]

Hi, well you could play a part of the animation, but that setup would probably be a bit complex. if you create a bunch of takes/animation you could play them back and use basic if statement setup to see how far along the line you are. however if its simple movement you are going for. I would suggest just scripting the movement of the gameobject. this post might help you: answers.unity.com/questions/667641/how-do-i-move-my-2d-object-using-arrow-keys-also-h.html

[@redinternet9893]

why my rotate animation is fast > slow > fast > slow (loop)

[@CubicBrain]

Hi Ken, You need to select the keyframes in your animation, and set them to linear. this way the wont do bezier/easing animations.

[@redinternet9893]

where can set linear

[@CubicBrain]

In the "Animation" window, with your gameobject selected you should be able to see the Rotation (like in the video at 2:30). if you select the keyframes, and right click then, in the drop down menu you can change the "Tangents". if you choose "both tangents" and set them to "Linear", you animation should be smooth.

[@ashoan8965]

What about uh, this is for my car game... I want a door to open and stop on the press of a key, and if pressed a second time, it reverses, the door would close, like if the animation is reversed and stop like it did when opening the door. hood trunk it could be anything.
