I created a bunch of non-AI animations for enemies that do basic back.forth or up/down motions. Everything was working perfect until I started working on the Boss of the level. The boss has his own tag "Boss" and enemies have their own tag as well. Anyway, the problem is when I click start, every enemy leaves the game board. I can see them animated above the game board still doing their routines.
Any clue as to why this happened and how to fix it? I'd really, really hate to have to scrap all the enemies and start from scratch...
I used the Animation tool inside unity.
Extra Note: I created an EMPTY and moved all of my enemies into that Empty object to clean the hierarchy panel up. The animations were fine before this.
************** Currently Resolved **************
Whew! Okay, so apparently Unity doesn't like it when you move your animated stuff into an empty AFTER being animated. I FIXED them by simply removing them from the EMPTY that I had placed them in. However, I'd still like to know why this is. So any useful resources, links, manuals, personal insight/observations or anywhere I can read up on this would be appreciated!
Here is an explanation what happened:
The moment you dragged them all into the empty GameObject I guess this object probably wasn't placed on 0,0,0 in the Scene.
So Unity automatically changed all the local position values of your enemy items to fit the current position offset to the empty object.
Result: In the editmode they don't change their actual global position in the scene but their local position. This is supposed to happen if you just want to organize stuff.
However, now when you start the game and the animations are played, the animators change all the local positions to whatever is stored in your animations.
Result: all objects jump back to their original localPosition which had an offset to the empty GameObject.
To solve this make sure the empty GameObject is at position 0,0,0 and optimally has rotation 0,0,0 and scale 1,1,1 before you drag anything into it.
Easiest way to achieve that is by clicking reset in the empty objects Transform component before starting to drag stuff into it.

In my Unity 3D project I've added an animated body as a child to the Player object. The player moves as is should, with the right animations displaying for each key. The problem however is that the transform of the child changes when I enter game mode, meaning the character is walking above the ground. In scene mode it's relative to it's parent, it's grounded, but when I switch to game mode the character suddenly changes it's y-axis transform. I also checked the inspector for this object, it's y-axis changes.
I tried disabling the movement script, to check if this could have anything to do with it, but nothing changes. The transform still changes. I'm new to this problem, and every thread I've found on the topic hasn't helped much. Does anyone know what might cause this?
The hierarchy. mixamorig:Hips is the one changing it's transform. The animations and animation skin I'm using is from Mixamo.
I've created a prefab of a trophy in unity. But when i drag and drop prefab to the scene, it appears in the wrong location. You can see at the photo where i drop it(red circle), and where it appears(green arrow).
Same happens when i instantiate it with a script. it appears righter and higher than i click.
As far as I can see, there is an animation in your prefab.
Make sure no coordinate points are registered in this animation clip.
It looks like there is an animation on the trophy. I think what happened was you moved the prefab with recording toggled on and thus, the outcome would be like that. All you have to do is edit the prefab's animation and at the start of the animation, set the position to 0 on all axis. If the problem is still there, check the script, maybe there's something wrong with that? Also if you're still stuck, edit your post with the script. And when I say 'the script' I mean the script that instantiates the prefab.
I hope this helps in some way! :D
So i'm working on this project and i'm using it to finally learn how to animate in 3D (taking a small break from coding hehe)
So here i am faced with a problem and i have no idea what i did wrong. First let me explain how everything works.
So the Animator is attached to the player, and the player obviously has a structure of legs arms...etc
everything inside the player is being animated by this animator.
So i have a weapon (a wooden sword) that has it's pivot attached to it's bottom (in case it helps to know)
i'm animating it from that pivot point, which happens to be the parent to which the sword model is a child to.
When i hit the V key the weapon gets instantiated in the player's hand (which is an empty gameobject) and when i press the F key the player attack and activates a trigger in the animation that starts the attack animation.
But the animation is not working properly. more precisely the key frames of the weapon are not being player(as you can see in the video all the rotation axes give the coordinates of 0 0 0 throughout all the animation.
But, ...and this is where the strange things start!... when i manually go through each second to play the animation and see what's happening, you can see that those coordinates start to change and it shows the animation exactly as it's supposed to be. then when i switch back to idle state so that i can start moving around the player normally. when i hit the F key to attack the correct animation is player and no problem happens... Magic? i don't think so... :p
what do you think? what could be causing this problem.
Who's up to solve my riddle :cool:
Seriously guys what's going on here, i need help.o_O
Thank you all ;)

In general: You are using an ALPHA version 2019.3.0a4 ... in short don't.
As any alpha version it is like to have some bugs .. especially since you are not even using the latest instance of the alpha which afaik would be 2019.3.0a12!
2019.3.0b1 is actually even already in BETA state a lot of former bugs should be fixed there - but it is still a beta release meaning it is not ready for production.
So in general don't even use the beta. Rather stick to the latest stable release version which would now be 2019.2.3f1
There is not directly listed one relating to the animator not finding a certain object at first and then not animating it .. but as said alpha version are likely to have bugs. Also since it is an instantiated prefab the original instance will be gone .. then by name it gets re-assigned by the animator so the main issue might be that you instantiate it in the first place instead of just having it already from the beginning.
You should consider only using the parent/pivot object of that sword and not animate the sword itself at all. Simply spawn it as a child of the animated pivot and you should be fine,
Sorry I know the title is really confusing.
Basically the camera and hands are nested under an empty object. This empty object is then used to rotate the character and teleport the character. Thing is, the camera is able to freely move around and away the empty object. Making rotation seem like you're running in a circle instead of just rotating. Then when you teleport it's a little offset. Like if you shoot the teleport beam straight down you move because it's teleporting the empty object to the camera which moves the camera.
So if the headset and camera aren't exactly on top of the empty object everything gets wonky. I understand the problem just can't figure out a solution.
I tried resetting the position on every teleport but you can still move away and spin in circles. As well as resetting resets the orientation and that's not exactly what I need.
Any help would be greatly appreciated.
There's a few ways to approach this. A crude, and not very elegant solution would be to parent your camera parent to yet another object, created in runtime, that would assume the position of the actual player camera when the rotation starts. You can reparent objects dynamically, so you could rotate this newly spawned object, which would give you the desired effect, and then loose the top parent when the rotation stops.
Alternatively you could move your camera parent as you rotate it, based on transforming the position relative to the player camera position. A bit more elegant but there's probably a few lines of math that you would have to write
I would like to move a tile with drag and drop in Unity 2D. The tile is a sprite. The scene is an 'Unblock me' or 'Blocked in' like gameplay.
Because the tiles in real life correspond to physical objects it seemed be to a good idea to model them with colliders and rigidbody. The border of the table surrunded with invisible colliders. I hoped these will constrain the moves of the tiles realistic, when the player moves them.
Then I implemented a simple (mouse based) drag and drop behavior which is worked perfectly except the moved tile penetrates to other tiles and the border, and sometimes jumps over them. Then I learned if I am overriding physics by explicitly setting transforms position (which I do exactly in my drag and drop implementation), this will happen. OK I accept, I should set only forces, ect. on rigidbody never directly the position.
Now the question:
I am stuck here. I still want to drag and drop like user experience, and some realistic visual result. When in the real life a player moves a tile, it seems it is "glued" to its finger. How can I achieve this (ot at least similar) with just applying forces? Any suggestions or point similar existing sample/blog code?
(I know as a backup plan I can omit all the physics and constrain the tile positions by code, and create some tweens to move the tiles. Is the real solution (what I am asking for) so complicated I should vote on this backup plan?)
Edit
According to comments I've added a video:
There is nothing wrong with the way you are manipulating your dragging. The beauty of developing is being able to do things in your own way. If it works for your game, then don't fret.
Now, i recommend:
Create a new physic material. Assets > Create > Physic Material
Set your new physic material inspector settings both to 0
Attach the physic material to all your wall object colliders. This should allow for your object being dragged to move smoothly against the walls without chopping.
Do a check to see if your mouse is over another collider. If so, then stop the movement in that direction.
Since your movements seem to always be on a single axis, on collision, tell your object to snap to the edge of the wall object. You know the Wall position and scales, also you have the position and scales of the object being dragged. with that you can write a function that will offset it to the correct position when the collision occurs.
Let me know if any of that works out :P
