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.

I was going to use the VideoPlayer to render to Camera Near Plane, but I also want to display subtitles for the video for the sake of accessibility. I'm wondering what the best way to do that is.
I can't see anything on a canvas if I render to Near Plane. I'd like the video to appear in front of the scene so that I can have the scene there once the video is complete.
Do I need to be using a render texture to achieve this? Seems like a render texture might incur some unnecessary overhead for my purposes, but I could be wrong.
The idea is this:
Far Background - Scene
Background - Black Image (so i can fade to scene)
Middleground - Video
Foreground - Subtitles
More info:
This is a 2D point and click adventure game with a pre-rendered cutscene.
You could do this with a render texture, place it in front of the camera at an exact distance and size, but I wouldn't. Probably would be a different camera anyway for lighting or clipping purposes.
I would use a second Camera, rendering over top of the Main Camera, with the subtitle UI's canvas targeting the second camera's screen space, and clearing depth only. It will render what it sees, but with a totally transparent background. Then, you can render your video on either the main camera's near plane or the new subtitle camera's far plane.
You could put your black square in front of this camera, too, though it would be in front of the video. It could be UI on the main camera, or stick a third camera in between them. You might have to worry about performance if there are too many cameras, but I have used two or three before to no noticeable performance hit.
Robert Mocks's answer is perfectly tenable and makes sense to me. Thank you for that!
What I decided to do instead was use a RawImage so that I wouldn't have to deal with extra cameras. This way I can use the canvas as I normally would and don't have to deal with render textures.
This involves using the API Only setting along with the following code:
rawImage.texture = videoPlayer.texture;
That seems to work well for me.
I'm trying to make a 3D tour for cardboard. I'm putting my 3d image inside a sphere with a shader but I've noticed this problem. The ending point of image is very visible and disturbing.
And middle of the image is looking kinda wavey and distorted.
Just use a seamless texture or make one with Photoshop. for more info search seamless textures in google.
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.
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.
I'm new in Unity and i've realized that it's difficult do a multi resolution 2d game on unity without paid 3rd plugins available on Asset Store.
I've made some tests and i'm able to do multi resolution support in this way:
1- Put everything from UI (buttons etc) inside a Canvas object in Render Mode Screen Space - Overlay with 16:9 reference resolution and fixed width.
2- Put the rest of the game objects inside a Game Object called GameManager with the Canvas Scaler component in Render Mode Screen Space - Camera with 16:9 reference resolution, fixed width and the Main Camera attached. After that, all game objects like player, platforms etc inside GameManager need to have a RectTransform component, CanvasRenderer component and Image Component for example.
Can i continue developing the game in that way, or this is a wrong way to do the things?
Regards
Also don't forget GUI, Graphics. It's a common misconception that GUI it's depreciated and slow. No it's not. The GameObject helpers for GUI were bad and are depreciated, but the API for putting in OnGUI works great when all you need is to draw a texture or some text on a screen. They're called legacy, but there are no plans as to remove them, as the whole Unity UI is made out of it anyway.
I have made a few games just on these, using Unity as a very overengineered multiplatform API for draw quad.
There is also GL if you want something more.
Just remember - there will be no built-in physics, particle effects, path finding or anything - just a simple way to draw stuff on the screen. You will have total control over what will be drawn - and this is both a good and bad thing, depending on what you want to do.
I will not recommend you using Canvas Scaler for developing a complete game. Intended purpose of the canvas scaler was to create menus and you should use it to create menus only.
The 2D games created without the canvas scaler don't create much problems (mostly they don't cause any problems) on multiple resolutions.
So, your step 1 is correct but for step 2 you don't need to have a canvas scaler component attached.
Do remember to mark your scene as 2D (not necessary) and your camera to orthographic (necessary) while developing 2D games.
