I have a player model from the unity third person starter assets, whenever I attached a Character controller component, the center of it seems to be at the feet. I know I can adjust the center in the component to fit the player model, but is there a reason why the center of the character controller is at the feet? I tried other player models and got the same results.
The character controller is centered on the object's origin. For a rigged model that origin is typically the root bone located at the feet.
There is a special addon required to properly show bones in Unity, so I'll just display it in blender.
One could make the argument that the character controller could take this into account and automatically compensate, however this isn't possible since not all models follow this standard as you can see with this popular Uganda Knuckels rig.
On top of that you might be using the character controller for a character that isn't humanoid. In such a case any attempt at automation would fail.

Hi, I have a question when building my first unity project. So currently I am trying to create a character and add it into my scene.
As you may notice, the lower part of the picture are my characters, and the center part is my scene. However, after I adding the character into the scene by adding it in Sprite Renderer, instead of having the right character, I can only see a small circle. However, in the game the character appears perfectly. Therefore, I wonder if I can try something to make the character also be visible in the scene as well.
I am implementing a "companion map" for a HoloLens application using Unity and Visual Studio. My vision is for a small rectangular map to be affixed to the bottom right of the HoloLens view, and to follow the HoloLens user as they move about, much like the display of a video game.
At the moment my "map" is a .jpeg made into a material and put on an upright plane. Is there a way for me to affix the plane such that it is always in the bottom right of the user's view, as opposed to being fixed in the 3D space that the user moves through?
The Orbital Solver in MRTK can implement this idea without even writing any code. It can lock the map to a specified position and offset it from the player.
To use it what you need to do is:
Add Orbital Script Component to your companion map.
Modify the Local Offset and World Offset properties to keep the map in the bottom right of the user's view.
Modify the Orientation Type as Face Tracked Object.
Besides, the SolverExamples scene provided by the mrtkv2 SDK is an excellent outset to become familiar with Solver components
Long-winded question out of the way, I'll provide a diagram of what I am going for:
The red square represents the character, the blue rectangle represents the camera, the green dot represents the center of the "stage", and the black circle is the stage itself.
What I desire is to essentially lock the player's movement around the "center" of the stage, so that anytime you move left or right you are more or less rotating around said center. However, I also want the player to be able to move forwards and backwards to/from the center as well. Keep in mind I want the camera to always stay directly behind the player. I have tried many different methods, and the latest is the following:
I took a default actor, attached a spring arm, attached a child actor to that (gets possessed to become the playable character), attached another spring arm, and finally the camera to that. I then added the blueprint code to the first spring arm so that it was the one being controlled by the left/right controls. However, upon hitting play, the only thing that moves is the camera, and it can only move forwards and backwards.
I'm admittedly pretty new to Unreal Blueprints, so any help would be appreciated.
Alright, I figured it out.
Here's the setup needed if anyone else wants something similar.
For the player themselves, you'll need something like this:
The important thing is to center the root mesh where you want to rotate around. The spring arm's target arm length will be affected for the player mesh movement, giving the illusion you are physically moving the character. The second spring arm isn't necessary unless you wish to have more control over the camera to player distance.
For the rotation Blueprint, you'll need this:
The target is whatever you named the root mesh. (Mine was called Center) Drag and drop it from the hierarchy.
For the forward/backward movement, you'll need this:
The target is what you named the spring arm. (I left mine as the default "SpringArm") Again, just drag and drop it from the hierarchy.
Adjustments in Project Settings:
Yes, my inputs are backwards from what you'd think. I felt it was quicker just to reverse the inputs instead of adjusting whatever was causing the movement to be backwards in the first place. (It's probably just the sphere orientation.) Also, you'll notice I have the w and s inputs set to 5 or -5 instead of 1 or -1. This is due to the fact the movement was slow otherwise. I'm sure there's a fix that doesn't involve changing the input axis scale, but honestly I won't really have a reason to alter the values at any point in my project. If it ever comes up where I do need to, I'm sure there's a bypass to change the values from within blueprints anyways.
End result:
End Result Video
If I remember correctly, child actor components are a bit different from other components in that they are transformation independent, that is they do not update their transformation when their parent component moves around.
I find it a bit strange that you would separate your player actor and the camera component. Normally, the player "pawn" contains the mesh and camera components for one player.
I would suggest you do the following:
Create a player actor (e.g. a "pawn" or "character" class)
Create the following component hierarchy:
Root Scene -> Spring arm -> Skeletal or static mesh -> spring arm -> camera
Your root scene is the green center in your drawing. You can then basically use the blueprint you already have to rotate and move your player.
I'm completely new to Unity and I'm starting to work on a little game for my class. The scenario says that the main character should be placed in my home town.
Since I'm not capable of modeling my town, I tried making skybox from google street view images using free plugin I found. It looks ok, so I tried adding an avatar, and that's where I'm having troubles.
When adding an avatar, he falls trough the floor, I suppose because its only image underneath him. Then I tried adding box below his feet, and now he levitates in squat position abowe it.
Has anyone any suggestions or ideas on how to fix this? Or maybe some suggestions on different vay of doing this would also be apprechiated.
Here is a photo of what it looks like now:

The reason your character falls is because there is no "floor" yet. The skybox is nothing but a special cube that wraps infinitely around your scene. With the street view images it may appear like the character is standing on solid ground based on the optical illusion of the skybox, but they're actually floating in space. When you press play, the physics engine starts, gravity takes hold, and your character falls.
There are a number of ways to prevent them from falling.
Disable Gravity on Character
This is only a good idea if you're not planning to use physics in your game.
Select your character's root node in the Hierarchy
In the inspector, find the RigidBody component
Uncheck Use Gravity
Add Floors
Add something with a collider on it that doesn't have a RigidBody. The collider will prevent the character from passing through it and the lack of RigidBody will ensure it doesn't also get affected by physics or gravity.
Create > Plane
Set its transform position to 0, 0, 0 so it's centered in the world
Scale it up big enough for your character to land on
Uncheck the Mesh Renderer in the inspector to make the plane invisible
I have two cameras that occupy different spaces in the Game view. The problem is that I can interact with my object shown by the main camera, but when I move this object (in scene view) to make it appear in the visual field of the second camera, the object is displayed in Game view but I can't interact with it (the object is a scroll Rect btw) through Game view. Seems to have a very simple solution but I couldn't find it.
Here are the parameters of both cameras:
Main Camera:
Pretty sure you can only interact with the current MainCamera in Unity.
If you could explain what you're trying to achieve with 2 cameras maybe we can help you find a better solution.
