I want an enemy to look at the player when he shoots him, I call this function from an animation event:
public void ShootPlayer
{
thisTr.LookAt(playerTr);
thisTr.rotation = Quaternion.Euler(0, thisTr.rotation.eulerAngles.y, 0);
GameObject newArrow = Instantiate(straightFlightArrow, shootPoint.position, transform.rotation);
em.canMove = true;
}
It does get called, but model`s rotation does not change. The weird thing is, if I invoke thisTr.LookAt(playerTr) in Start(), the model will rotate accordingly during the shoot animation. Also, if I rotate the model from another script the same way before the shoot animation starts it will work as well.
So for some reason trying to rotate the model specifically from the animation event does not work for me. I have tried checking constraints on and off, applied and disabled root motion, but there is no effect. I am sure that there is some obvious mistake that I make, but I just can`t figure it out.
Properties that are being animated (i.e. inhibited by the animation engine) cannot be set from code. There's a workaround for it, but it's ugly - you need to do your update in LateUpdate() (so it's after the animation engine does it's transformations) and you have to keep track of the updated value, overwriting it each and every frame (because otherwise the engine will overwrite your next frame with what it had calculated).
Other workarounds involve wrapping GameObjects in empty GameObjects, i.e. my animator animated an object's position, which I wanted to change in code as well, so my structure was:
animatedContainer
|- actualObjectAlsoAnimatedFromCode
As far as I know this also applies to properties which are inhibited at some point, but not necessarily changed during current animation (and I think this is the issue your case is facing).

I'm trying to make a game where you're a boy and you can transform into a deer.
I don't know how to make the player transform into a deer when pressing a button. Can someone please tell me how to make the player transform into a deer when pressing a button and how to make the deer transform back into the player when pressing the button again?
There are 2 ways depending on what you want exactly.
1.Transformation without an animation, you can do this by having 2 separate models
public GameObject boy;
public GameObject deer;
//Give both objects the same tag and don't add anything else under the
tag in order for this to work
private Transform currentPosition;
private void Start()
{
deer.SetActive(false);
}
public void TransformButton()
{
currentPosition = GameObject.FindObjectWithTag(LayerMask.NameToLayer("TransformationTag"));
//Unity doesn't pick up disabled GameObjects so it will pick up only the
//active state (the active object)
boy.SetActive(!activeInHierarchy);
deer.SetActive(!activeInHierarchy);
GameObject.FindObjectWithTag(LayerMask.NameToLayer("TransformationTag")).getComponent<Transform>() = currentPosition;
}
I recommend this way if your deer and boy have different scripts
you could also play an animation on click (apply this animation to the active character) and when it is done (below is how to check if it is done) you can trigger the code above
https://answers.unity.com/questions/362629/how-can-i-check-if-an-animation-is-being-played-or.html
I am pretty sure there are other better ways but this is the way I do it
The other way which is probably easier if you are good at animating is to just trigger an animation using the animation bools when the button is clicked but I haven't tried this way because I'm not that good at animation. Instead I use the first way (usually for switching skins in a shop for example) but I never did animations that completely change the size ratio so much so I don't know how well would it work (I usually do 1:1 transformations like humanoid to humanoid or tank to tank so you will have to experiment a bit)
I dont think that this is possible in unity. Maybe there are some Assets that offer something like this.
But you could create a similar effect with Blender.

There are some cool tutorials out there Morphing Shape Animations in Blender
Today my tutor was helping and explaining to me how to add animations into my game, we added wobble effects to my 4 buttons. (pink, blue, yellow, purple) We fully compelted the first button together and then he left me to do the other 3 using what he had taught me. I thought I had done it correctly beause after adding the need code to all 4 of the buttons the pink button's wobble animation works, but the other 3 don't do the animation.
I was looking through to see if something was different and in the Animation dock they come up yellow and say (Missing!) even the pink button that works has this come up. I don't know what this means or how to fix it and would appreciate if anyone could help and explain this to me! Thankyou.
{
if (Input.GetButtonDown("Horizontal"))
{
if (Input.GetKeyDown(KeyCode.LeftArrow))
{
//play pink wobble animation
m_Animator.SetTrigger("Pinkhit");
}
if (Input.GetKeyDown(KeyCode.RightArrow))
{
//play purple wobble animation
m_Animator.SetTrigger("PurpleHit");
}
}
if (Input.GetButtonDown("Vertical"))
{
if (Input.GetKeyDown(KeyCode.DownArrow))
{
//play blue wobble animation
m_Animator.SetTrigger("BlueHit");
}
if (Input.GetKeyDown(KeyCode.UpArrow))
{
//play yellow wobble animation
m_Animator.SetTrigger("YellowHit");
}
}
}
The property key frames in AnimationClips are string based on the property paths which include the type names of the component and the field names they belong to.
The (!Missing) can mean e.g. the following
you removed the according MonoBehaviour from your object
you renamed your according MonoBehaviour class
you renamed the animated fields
this AnimationClip was originally for another object and now you are trying to use it for an object which doesn't have according MonoBehaviour / component attached. (which basically equals the first case)
You renamed or changed the hierarchy structure of the according child GameObject which is nested under the one with the Animator attached. (Renaming the root object would not be an issue)
therefore the according property paths that should be animated by your AnimationClip can not be found on this object.
Since the Scale belongs to Transform which is a component each and every GameObject has to have none of the upper points can be the case here and you most probably happened to rename the object like so:
This is of course a little bummer especially when working with prefabs, bu for the AnimationClips to work properly
either make sure to put the Animator directly on the object that is supposed to be animated (in that case naming is no issue)
or make sure you don't rename or change the hierarchy structure of according child objects
I'm currently having a problem with Unity Animator and I haven't found a solution yet. I'm trying to animate the position of a UI object through its Anchored Position with Unity Animator. Even though I have the checkbox Apply Root Motion active, when the animation ends it returns to its original position, instead of maintaining the position that changed.
I activate the animations through Triggers in a Script, and all the Scripting logic works well. The expected behaviour would be like you can see in the gif, but moving through the connectors instead of turning back to its original cell.
I tried to make an Empty GO the parent and animate child, remake the animations, remake the animator, etc., but nothing worked so far and I don't know what to try next, and I could use some help.
Thanks for answering! I will answer anything necessary when asked!
Current State Gif:
Animator Screenshot:
I can't be sure why your apply root motion is not working as it should but you can fix this in another way.
You create 3 animations with the Anchor Position, one at the startpos, one for the transition from the first one to the end one, and the endpos.
Start animation and end animation should be looping while for the transitioning one you can uncheck the looping in the inspector of animation
In the animator set the startpos as default state and create a transition with the trigger to the moving animation. Then add a transition from this animation to the idle end position without a condition but just has exit time set of the time the last animation will play
In this way, it should all work fine and if you want to come back to the first position you can add another transition with a trigger to the start or whatever you prefer.
I have a game I am making where I want that the player has no animations until it hits a certain trigger. Then I want a short animation to be played, then it will stop the animation again.
To get this effect I have the above animator state machine attached to my player, and when the player collides with the trigger it plays the Halfway animation, then it goes back to the empty state. All of this seems to work fine at first but while my player is in this empty state loop thing, I cannot move it. I am using "rb.velocity = new Vector3(stuff);" to move my player, and when I disable the animator component I can move fine. I was wondering if
There is any way to enable movement while I am in this empty state,
There is some way to get rid of the entry transition entirely so I don't have to have the empty state at all, or
Pretty much anything else that would make this work :P
If you need more information let me know, I will try and help you help me as much as I can. Thanks!
I am a total beginner at Unity3d. I have some background in android programming, but no C# experience whatsoever. The first thing I am trying to do is to create a clone of flappy bird game, called flappy plane, according to this tutorial
http://anwell.me/articles/unity3d-flappy-bird/
The problem is, when I tried to write a script that allows player to move (player.cs) with the code
using UnityEngine;
using System.Collections;
public class player: MonoBehaviour {
public Vector2 jumpForce = new Vector2(0,300);
public Vector2 jumpForce2 = new Vector2(0,-300);
// Use this for initialization
// Update is called once per frame
void Update () {
if (Input.GetKeyUp("space")){
Rigidbody2D.velocity = Vector2.zero;
Rigidbody2D.AddForce(jumpForce);
}
}
}
I get an error "An Object reference is required to access non-static member 'UnityEngine.Rigidbody2D.velocity'". I have googled that and it is suggested to access Rigidbody2d with GetComponent().velocity,
so I changed
Rigidbody2D.velocity = Vector2.zero;
Rigidbody2D.AddForce(jumpForce);
with
GetComponent<Rigidbody2D>().velocity = Vector2.zero;
GetComponent<Rigidbody2D>().AddForce(jumpForce);
The error is gone and I am able to add the script to the object, still I don`t get the desired action - after I hit play the object turns invisible and just falls down, does not react to spacebar button. What am I doing wrong?
Thanks for the answer.
It's possible that you're not adding enough force to have the object move upwards.
There's technically nothing wrong with your code. (Although you do have somethings mixed up in your question). The problem is in the fact that you're not adding ANY force upwards every single frame.
Essentially, at the moment, your player object is in free-fall the instant you hit the play button, and you're adding a minuscule force to the player only on the frames that the space bar is pressed.
To solve this, here's what you should be doing
Add an upward force to counter-act the force of gravity every frame. You can do this in two ways.
a. Set the rigidbody's velocity.y to 0 BEFORE detecting the space bar (this is really a hacky way, but it'll suffice and doesn't need any more code)
b. Add an upward force to the player which will nullify the effect of gravity. Just use F = mg to get the value of force you'd need to add.
You could, alternatively set the isKinematic property to true by default on the Player's rigidbody, set it to false on pressing the space bar, and back to true after a few frames (5 - 6 frames)
make sure your player object and the ground both have BoxCollider2D colliders to keep above ground.
you could keep a reference stored for the rigidBody like Rigidbody2D myRigidbody;
then in start put myRigidbody = GetComponent<Rigidbody2D>(); then you would use like myRigidbody.AddForce(jumpForce); your jumpForce2 though is shooting your player downward you should not need it in a jump as the physics and gravity will apply with the rigidbody.
incase your input is not set up in the project settings try to fire the jump with
Input.GetKeyDown(KeyCode.Space);
