I am currently working on a unity project and I have a stickman built by Hinge Joints but when I animate his legs and activate the animation, the legs stays at the same position and the rest of the body is moving forward.
How can I animate the legs without freezing it's position?
This worked for me:
Anchor and Axis should be correct, if it works with a motor.
For testing, deactivate "Use Spring", "Use Limits" and "Use Motor".
If it still doesn't move, you should have a look at the rigidbody. "Is Kinematic" should be deactivated as well.
From here
A lot of time passed since I asked this question and when I read this question again I figured out that my mistake was animating the legs without a parent.
The legs hadn't a parent so their positions where the animation position.
But if I had setted the legs as children of an empty game object, their positions were relative to the empty game object, which I could move as I wish.

I've got a plain 2D Capsule Sprite. I want it to rotate around a specific point instead of its very centre. In other programs, this point is called the anchor point. For context, I'm making a paddle for my 2D pinball game so obviously the paddle needs to move when you press a button, but I can't have it moving around its very centre... Well, I could but I don't want to.
So my questions are:
Is anchor point the correct term for Unity?
Can this be altered/moved and how?
So, I ended up getting an idea from a friend who does this stuff too.
I made an empty game object. Made it the parent of my paddle. Moved the paddle to the point of the game object where I want the paddle to rotate around, and now when I rotate the game object, it rotates the paddle around the pivot point that I want it to have.

Edit: Just works using UI components within a canvas
You can use the Anchor presets of the Rect Transform. Or define the Min/Max values for x/y coordinates in Anchors Property.
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 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.

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.
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
I'm making a fps game and I want my character's arms to rotate up and down depending where the cursor/camera is pointing at. The character already rotates when I turn left or right. Hopefully someone can answer my question. I'm new to Unity and I'm still learning how to code in C#.
For top and bottom rotation, create an animation for top aim, eye level aim and feet aim. send the value of your rotation to animator controller and animate according to it.
