Make 2D particle system in Unity - unity3d

SO I saw a tutorial online how to make a particle system, and I made it. Only thing is, I want to use it for a 2D Menu. So when I add the particles in front of the canvas, they don't show up in 2D. How do I make particles that will show up on a 2D menu?

You can try positioning your Canvas in World Space, then moving it behind the particle system. This will allow the Canvas to be positioned like all the other objects in your scene, and no longer be constrained to the camera.
Here's a guide from Unity on how to do it.

Why do certain sprites ,look as if they're further back in the window?

I am learning how to make games using unity, i have used free sprite packs from unity's store.
i have selected each individual sprite and changed its z position to 0, but when the game runs it looks completely different to how it looks in the editing window.
please help.
Here is a video I recorded.

Are your sprites on a prefab, or children of another game object? The Transform of the parent object affects the transform of all children.
It looks like this is a camera problem. Your camera is set to perspective, it is possible to do parallax backgrounds with a perspective camera and you may have already accomodated for it, but that is the first thing I would check.
You can modify this by going to your Main Camera and selecting Orthographic from the Projection drop-down menu.

Clamp camera within bounds of a Polygon Collider?

Hi I am making a 2d platformer game and right now I am working on the camera. while I succeeded in clamping the camera inside a rectangular shape, my game involves slopes, so I want my camera to be able to clamp inside a curved shaped too. Can anyone help me find an idea for the code?
Cinemachine gives you a flexible 2D camera controller, with the option to confine it inside a PolygonCollider2D. This section contains explanation for that and other cool things.

Models in unity from Blender

i'm making a tank based game and when i made a model of the tank in blender and imported it to unity. When I placed a camera inside the wall was completely transparent from the inside but not the outside.
Is there any simple fix to this problem?
In blender you have to make sure your normals are facing outward. If you are using planes imported from Unity they will only show up on one side, its better to use cubes if you want them to be visible for both sides. If you are using a plane you can create a custom 'CULL OFF' shader so that backface culling will disable on its material and will show on both sides.

Implement Zoom(using UI Canvas) in Unity 2d game

I want to implement as showed in the below image in 2D game, I can find so many tutorials for 3D like mini map concept but for 2D i couldn't find anything. In my game i want to show a secondary
camera as in below image and also i need to zoom the content that will show through it. I developed one concept but it can be done with sprites or with Canvas in World Space mode. So you can see
they won't resize or positioned according to the screen resolution. If you guys have any idea how to do this task,it will be very helpful for me. And i also tried with depth mask shader .Thanks in advance.
Use a camera with target texture
Follow my tutorial here: Particles with Dynamic Text but disregard the parts about the particle system, they are irrelevant for you.
Once you've made a material, stop following the tutorial, and instead:
Create a sprite renderer on a canvas that is "Screen Space - Overlay" and set the material to be the one that you created.

Google Cardboard "Game Over" screen with a designed image

I am trying to implement a game over screen for my Unity 3D based game for Google Cardboard. I have tried using the image UI component on a canvas component. The image appears just fine but the issue is that it seems to show up over the reticles. I would like to have the image perfectly fit the inside of the reticle. I am considering somehow finding out (somehow) the size of the reticle and exporting my image as a png with transparency around its graphics.
My Question:
Is there a better way to do this? If not, what are the dimensions i can use for the duplicate images (for the two reticles) to perfectly fit the Google Cardboard reticle openings.
When using Google Cardboard (Now GVR), I think it is best to use Quad GameObject for Game Over screens to which you can add images and child objects like 3D Text and collection of child quads.
The best thing about using quads and 3d text is the extent of scripting that can be done to make them dynamic as well as styling. And in your case, Physics Raycasters work well for the reticle to interact with those GameObjects.
You can add materials and textures to the quad and what not! I personally love quads for GameOver screens as well as a lot of other interact-able things.
