I am working on temple run like game using this Kit. https://www.assetstore.unity3d.com/#/content/3292. I want to insert a room with two doors , when my player enters in the room it stops running and user can control with arrow keys , and when it leaves the room by back door it starts running again . what should i do when it collides with the door collides ?
I am doing this by replacing the scenes. I am instantiating an empty Game-object prefab in GamePlayScene when player is colliding with that i am loading HouseScene and when it is colliding with back door (in HouseScene) i am loading GamePlayScene. but the game is starting from the beginning. how can I resume the game From where I left And keep the track of Distance covered and coins collected? And also for HouseScene . Remember the points i achieved in it. Thanks.
You need to save the informations that you want to keep between your scenes.
You have some possibilities about that:
1) Save your informations in a text file and retrieve those when you load a new scene (but this way is a bit "dirty" and not recommended...the next points of this list are better solutions);
2) Using PlayerPrefs. They provide getters and setters to retrieve/store data in/from the registry of your operative system.
3) Using an object (as a container) that contains all your "global" variables (the ones that you want to mantain between scenes' transition), and invoking the DontDestroyOnLoad function on it. That way, your "container" (with its data) will persist in the entire life cycle of the game.

When I shoot a projectile while running the projectile collides with the player, i.e. the player's collider is hitting the bullet's collider.
What is the best way to prevent this? By making a space between the gun and the projectile to avoid collision?
There are 2 ways I can think of right now.
1- You can create a selective collision script (or edit your existing one) and add an exception for the player object. So, bullets can go through the player. This is the main way to go.
2- You can use layers (or Z depth) and you can create a whole layer for bullet spawner etc. And make enemies also have targets in that layer/depth.
I don't have Unity installed on my current system right now. But I will install it when I get a chance, and if you don't solve it until then I will try to help properly.

I am following this tutorial: https://www.mvcode.com/lessons/roll-a-ball-obstacle-course
At the very end we created enemies (cubes) and their movement works very good. But as soon as I activate "is Trigger" they fall through the plane into the void. What am I missing?
I tried to pull them above the floor to have some space between the bottom and the enemies, but they keep falling through the floor and only when I got "is Trigger" enabled.
thanks in advance,
Akuma
Alternatively (for those people who want or need gravity enabled on their cubes):
Add a second collider.
There's literally nothing stopping you from doing this. You can make the trigger one bigger or just tweak the physics layers collision settings so that the collider keeping the enemies on the ground doesn't interfere with the operation of colliding with the player, etc.
It's likely that the cube is on top of the floor. When you enable "Is Trigger", collision is disabled and the cube would go through the floor.
The solution is to disable "Use Gravity" on the cube's Rigidbody.
Note that you are following a plagiarized version of the original "Roll-a-ball tutorial" tutorial which left out so many things. You should be following the original tutorial here. Watch the 10 seconds from this video which describes what you missed which is what I described above.

I try read all post like
http://forum.unity3d.com/threads/scenes-vs-canvases-vs-panels.279890/
http://forum.unity3d.com/threads/with-new-ui-separate-scenes-or-just-separate-panels.281013/
and others and still don't understand what is better way?
Scenes vs panels.
I'm personally thing scenes is better - I feel separate levels.
A game i try to write familiar to candy crush and how i understand they use scenes - because from map to play new matches gam you see loading screen - i thing this is some scene.
Thank you
because from map to play new matches gam you see loading screen
Because you see a loading screen does not mean that the game is actually laoding a scene. Anyone can put a loading screen up while doing something else such as loading AssetBundles and not actually loading the scene.
Your question will only result to opinion answer since you don't really have any problem.
I have my own rules I use after experimenting with Unity.
If you are making a 3D game with color map, normal map, height map and other textures, use Scene. Separate the scenes to speed up loading each level.
Now, if you are making a 2D Game as simple as candy Crush that uses few Sprites and Images simply use Canvas/Panels. Make Level 1 as parent Canvas GameObject. For level 2, simply duplicate the Level 1 parent Canvas, rename it to Level 2 then make a little changes to it. You can switch levels by enabling and disabling the parent Canvas GameObjects.
This make modifying your 2D Game very easy.You can easily compare what two levels look like by enabling/disabling them. You don't have to load up another scene to get another level. Also loading scene takes time too but this eliminates that.
Another advantage of this is that you can always convert the Canvas parent of each level into a prefab then import it into another level if you want to start using scenes instead.

i'm making boundaries for the characters in my 2d game in unity 5. I added box colliders to the borders and my characters but the characters don't stop when they run into the other borders.
I don't have much experience of Unity 5, but probably these things work similarly than with old versions of Unity.
Colliders can be used for stopping things to go inside each other without writing your own OnCollisionEnter function.
So there must be some other problem. Check that:
Colliders are same type. 2D and 3D colliders don't detect collisions with each other.
At least one participant of the collision needs to have rigidbody component attached.
Check that is trigger is not selected on any of the colliders
Pause the game and check in the scene view that the green boxes of the colliders actually colliding
Check the layers of the gameobjects and check if they are should collide because of the layer based collision
When the colliders intersect it will trigger an OnCollisionEnter event. You need to tell it what to do after that. It could be setting the velocity to 0 in the case of a ball hitting the wall, or it could be awakening enemies in the case of a player walking into a trap. You have to define the behavior.

I am trying to make a Liquid in Unity that Can be worked with and have functions. I am trying to make something more like Pouring water from a bottle to an empty cup where the water in the Bottle Decreases and the cup start to have water. I tried working with particle system but I do not seem to have control of the particles itself like for example when a particle collide with another particle they form a bigger particle and when an Event happens other functions to apply to them.
The game intends to be for phone platforms. I will be working with pixels.
You are correct to use particles for the water pouring effect. However, to achieve the cup filling up with water you will have to use some trickery. The water itself will have to be a plane or cube which rises or grows in size at a set interval while water is pouring or when particles collide with it. Personally I would just do a set interval, especially since it's for mobile, as collision detection on that level is expensive.
There is no way to script a particle system on the individual particle level (or form new ones). Particles are meant to be emitted and destroyed as quickly as possible. Having them form a part of the permanent scene is not a viable option for performance reasons.
