Unity3D - Trigger animations (keypress trigger)

@@spencer7985 The second if statement is when we press 1 again it start play new cube animation in this case it is idle animation by this way we can start or stop animation

literally the same thing

[@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).

Guys, I figured it out. To make it so the animation can be repeated is this Void update() { If(input.getbutton("Fire1") { Start Coroutine(EnterTextHere()) } Ienumerator EnterTextHere() { _anim.Play("animnamehere") yield return new WaitForSeconds(delay); _anim.Play("YourDefaultState") }

What if there were Different animations to be played on different objects then how will we be able to do that?

[@Skullcat2212]

How can i trigger an animation when pressing a hud button?

[@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).

[@kaldo_kaldo]

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

[@theotherone0101]

how can i do it. if it just should play the animation 1 time ?

[@CubicBrain]

Click the animation in the project field, and uncheck "Loop time", in the Inspector.

[@100percentpodcasts7]

Cheers

[@official420er]

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

[@rajjaiswal1606]

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") )

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?

Because i keep getting errors

[@CubicBrain]

You need closing } for tour update method and class (two of them at the end of your script).

[@HDMaco13]

You need to remove the -> " " in if (Input.GetMouseButtonDown("0")) It should look like if (Input.GetMouseButtonDown(0))

[@VindicatorMorty]

Great tutorial but after reading the title i thought you gonna use the anim.SetTrigger("TriggerName"); Method in addition with transitions.

[@CubicBrain]

Thanks!

[@camy_dev]

I really loved this thanks man I used it with a trigger to make a script to play when I'm in a trigger, but I was wondering how I specify in the script that i only want it to play once, in other words i have a dresser that moves when I press e near it but i only want you to be able to play this animation once otherwise you can move the same dresser over and over again any help would be appreciated thank you so much already though.

[@CubicBrain]

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

[@CubicBrain]

how about if we want our player collider with trigger box and play animation not press key button how we must change code

[@jasielt.2006]

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.

[@joshuaheejd]

I need some help with double keypress trigger animations? Meaning when i press e.g X, 1 thing happens and then when i press Y another thing happens to the same model. Are there any tutorials on this?

[@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.

@CubicBrain hello i´ve googeled for like 2 days now but i cant find any answers so i may bother you ^^ im looking for an animation on an instantiated object, my problem is as i set the animation up (just going up on the y nothing more) it takes the x and z axes aswell and my onmouse instantiate doesnt work anymore. the object doesnt spawn where i click instead all the clones spawn at the set up x and z values. i want to make a spell where the player raises a wall from the ground kinda like earthbender styled but i cant get it to work. thank you so much in advance if you actually answer it would make my day :) peace

[@CubicBrain]

Hi, I'm not sure how you would achieve the functionality that you are looking for. but, have you tried posting on the Unity3D forums? They are always willing to help.

[@drgitgud]

i had to place my wall into an empty gameobject to ignore its transform. my object was spawning right where animated it in the scene so it took the x and z values with it to avoid using them parent it. thanks :)

[@vlad-cristiansecatureanu6820]

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

[@BojanVasilev]

hello great tutorial but how can i make when i press again to animation stop and if i press again animation start again

Hi Bojan, You will have to set up an if statement, that looks for the animation state (which animation is currently playing.)

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.
