I try to do a 3d android game in Unity with c#. I put random barriers and code is works well. But problem is the barriers rotate comes wrong, I want to see from the front but they are coming from the side. How can I rotate them front? And how to fix overlap two barriers?

I am currently building a simple mixed reality application in Unity where you should be able to stack different sized cubes on top of each other. As soon as I add a third cube though, the collision seems to get weird. I have already played around with the rigidbody settings but so far nothing has worked. I have also enabled adaptive force.
You need to freeze the x and z axis on the rigidbody
In unity 5 I am having an issue with certain collisions. I made a basic maze-like game where the player controls a cube across platforms (made from other cubes). In certain areas, two or more of the platforms touch so the player can get to different areas of the level. The problem with my collision happens at these intersections. The player will seem to get stuck for no reason and they would have to back up and get a running start in order to get to the other platform. I went through everything and made sure they are lined up perfectly in the unity editor but nothing seems to fix this.
Any advice would be greatly appreciated .
EDIT: all of my objects are using box colliders
A common (and good) practice is to use a Circle collider on the bottom of your character object in conjunction with a Box collider.
For Example:
While this will likely fix your issue, the source of the problem is probably using many small tiled cubes each with their own colliders. A large amount of tiled objects with colliders most likely cause performance and collision issues.
I am making a multiplayer top down 2D game with 3d elements. All my movement, healthbars and basic functionality is working flawlessly even while hosted and playing on a server, node.js socket.io. However In this game it is possible to move the camera like in Realm of the mad god.
in case you are in doubt here is a video: https://youtu.be/4tdcxl3aZ0c?t=31s
This of course means that the players can end up being upside down with regards to each other and I cannot find a solution that works in all regards to make sure the sprites of the other players are always facing the correct direction with regards to their movement.
I have made several solution to this problem which cover most scenarios but while play testing other things we always end up noticing that the sprites sometimes face the wrong directions. So I am wondering if anyone has an answer, the logic, the fixing this problem.
Things I have tried:
Adding a gameobject to the camera to which all sprites asses their change in distance and determine their facing direction based off that information. (this leads to the players sometimes flipping erratically when the camera is moved and they as well are moving as sometimes they may be moving slower and there although moving left the camera approaches from the right and that flips them)
Adding a gameobject to the world which allows all sprites to have a fixed point to which they can measure their change in distance and therefore also know what direction to face (this worked somewhat better as they always know what direction they have to face, however once the player is upside down everything is inverted)
Emitting to the other players wether I am upside down or not in order to try to reinvert the above solution in the case I am upside down. (I could not find a good way to do this, and it got me thinking that this must be a problem people have fixed before many times and perhaps someone know of a good solution that works.)
thank you all for your input.
I seem to have found a solution for this issue that works decently well. Keeping in mind that I do not want to have the server being involved in this and I would rather have each individual sprite know its direction rather that have something heavy trying to determine this logic I came up with the following solution. May not be the best but it works. Still very keen to hear other solutions.
On my main character I have a switch case, which changes depending on the players rotation in the world. I need this switch case anyway for fixing (http://answers.unity3d.com/questions/1348301/trying-to-change-the-cameratransparencysortaxis-to.html?childToView=1348316#answer-1348316) that issue.
As the cases change I simply place the gameobject that I want the sprites to compare their distance to at 1 of 4 positions. YPos, YNeg, XPos, XNeg. Meaning that the sprite now determines its facing direction based on a gameobject that is placed in accordance with the Players position. without having to place it on the camera.
I will update if during further play tests this gives me trouble but thus far it works in the all the cases I need it to.
Still very willing to hear other solutions to this problem.
Thank you.
I am working on a tabletop game that user controls using accelerometer in the phone. It is pretty similar to Labyrinth on iOS.
The scene contains a tabletop created using planes and cubes, and a sphere as a ball. As it works in Labyrinth game, on tilting phone ball should drop to the tilted side, while the camera stays centered to table. I am trying to do similar thing where user tilts the phone, and objects on table move to tilted side.
Currently, I add the x and z component to Physics.gravity on tilt. Sadly, this change in gravity does not affect the ball which stays put on the table. Use gravity is selected for the ball, and it drop down from height to the tabletop initially and then comes to halt. After the initial drop, ball does not react to any gravity change.
I have also tried rotating the whole table, but using transform.rotate does not work either. The table rotates perfectly, alongwith the camera, but the ball stays put hanging in the air. So, currently I am out of my depth about the issue.
Is there any other way to allow tilt action registered, so that ball moves to the tilted direction? I cannot use addforce function, as there are multiple objects which need to react to tilt, and it will be difficult to keep track of that many addforce calls. How else can I get it working?
See this post for some related information.
As for why your sphere is sticking to the table, can I assume your sphere has a rigidbody? If so, you need need to wake it up:
if (rigidbody.IsSleeping())rigidbody.WakeUp();
Ideally you would make that call only after detecting a change in orientation/gravity, not every frame.
I want to make a simple 2D game where the user has to navigate a ball through a maze (using the accelerometer of course). I used a simple view to make use of the accelerometer and move a ball on the screen. Now how do I go about building the maze? Would I have to use cocos2d or something similar? How do I make the ball stop or rebound when it hits the wall of the maze?
Check out this game... it does a great job with the accelerometer and also setting boundaries.

This one is for Android rather than iPhone, but it has some parts that are very relevant to your project, such as moving a ball. Does not include ball rebounding or building a random maze; it loads mazes from a file.

For ball/wall bouncing, try this question.
For generating a maze, see this question.
