Unity button not clickable over other UI - c#

I have a single canvas in my unity project which holds 2 main gameObjects which are the Main UI and Pause UI. To make Pause Ui load I set time.deltatime to 0.
pauseMenuUI.SetActive(true);
Time.timeScale = 0f;
When I try and click my button on pauseUI it won't click or even show that it is being hovered over. ANy ideas as to what is going on?
When I am in the pause state I can still interact by clicking the main screen and the players gun will fire if there is ammo available so I know the game isn't broken. I think it might have something to do with Z index but not sure.
Pictures for use.

add EvrentSystem in the Hierarchy by doing tight click in the hierarchy Than search for EventSystem, plus be sure that the buttons properties in the inspector are set to intractable

Setting a button's alphaHitTestMinimumTreshold results into no call to Button.OnPointerDown

I want to create a button that has a custom shape in Unity.
I created a default UI>Button object and set it's Image to the following sprite:
It doesn't show it on this website, but the circle is the only part of this image that is transparent. It's a .png sprite.
When I set this as the sprite for my button, I could click on the entire rect transform of this sprite to activate the button using my button's OnPointerDown() method and un-hide some other sprites around it:
public override void OnPointerDown(PointerEventData eventData)
{
base.OnPointerDown(eventData);
Debug.Log("Foo");
}
Each time any part of the sprite was clicked, transparent or not, "Foo" would print.
Now I set the button alphaHitTestMinimumThreshold to 0.5:
GetComponent<Button>().image.alphaHitTestMinimumThreshold = .5f;
And as the docs suggest, I disabled atlassing...
...and enabled read/write for the sprite:
Yet now, when I click the button in my scene.. nothing happens. No matter where I click, "Foo" doesn't print anymore.
Then I tried changing the alphaHitTestMinimumThreshold to a lot of different values. Again, the entire button was not clickable anymore. If I don't touch the alphaHitTestMinimumTreshold at all however, my "Foo" prints again.
Why does changing alphaHitTestMinimumTreshold to any value make my OnPointerDown method to never be called?
So after 12 hours of messing around with all sorts of options, I found out that there were 3+ consecutive issues causing this behaviour.
If you ever run into your transparent buttons not working, be sure to try the following steps:
Make sure read/write is enabled in the texture import settings
Try if setting the Sprite Mode Mesh Type to Full Rect helps (sometimes the button's hitbox is off)
Disable atlassing under Project Settings > Editor > Sprite Packer > Mode
..and finally what did the trick for me: if you're working in a prefab that's nested inside another prefab (say your have a prefab for your button and then another prefab for your UI canvas/contents), remove the nested prefab from the parent prefab (aka remove the button prefab from the UI prefab), and just add it back in again. It was that freaking simple for me.
I triple checked whether my nested button prefab differed from the button prefab blueprint, and it didn't. But somehow, removing it from the UI prefab and adding it back in again solved my problem with a large sprinkle of magic.
With transparency buttons, I found that detection improves when the image is a child of the button object. So hierarchy is Canvas>Button>Image.
I know, old thread, but it came up so heres my solution:
It did all of the suggestions, but it didn't work.
HOWEVER,
What finally worked for me, was TO SPECIFY THE RIGHT SIZE. My game Object was elongated, but the sprite had "preserve aspect ratio" ticked. I just didn't bother to size it properly.
So when you have an image, set the size of the gameObject to the right dimensions.

Button in unity doesn't work, how can i fix it?

I am new to unity and I am still learning. I am making a game and its going great but I have a problem with a Quit button.
It doesn't use the script attached to the On Click () section in the button menu.
There's an EventSystem in the Hierarchy, the Force Module Active is checked, the button is a child to a canvas. I don't know why the button isn't working
Here is the code in the script attached to On Click ()
public void Quit()
{
Debug.Log ("YES IT WORKS");
Application.Quit ();
}
I want the program to close when the button is pressed but when the button is pressed nothing happens!
The function is not being called when the button is pressed which means that you have not selected the function in the onClick settings. To do this, ensure that the script is attached to the button and then dragged into the onClick box of the button in the inspector. Next, click on the dropdown and hover over the name of the attached script and select the function that you want to call.
Solution
Instead of using Application.Quit() try to shift the your working scene to the home screen .Your every game should start and end at the same level which is also known as the main scene of the the game. Secondly before shifting to other scene you should destroy your player and save the scores in the player pref .
Player Pref:
The library which helps the user to store the data and show them on the main screen , Hence the use of database will not be there in order to save the data for the small games . You are beginner so you should look at these all thing on You tube or the unity website documentation available on its website
Are you in the Editor?
Application.Quit() only works when you build the application (for PC and Android. It should not work on iOS, and even if it works it should display as a crash so it's not good).

How to control Unity Animation?

As far as I know, there are ways to manage Animation
Immediately,
Managing in the form of objects.
Managing with Sprite Images.
Is it effective to manage animations
in object format to manage character's joints in 2D animation?
What should I do to make it easier for me to understand Unity Animation?
As a beginner, we need a lot of data. I need your help. Help me.
I am going to explain the animation by manipulating GameObjects.
You need to add an Animator component to the GameObject you wish to animate. The animator component needs an animator controller. You also need to create an animation clip which represents an animation.(Animation controller is automatically created when you create an animation clip)
Now, to get started with animation you need to focus on animation clips. After you add an animation clip, you can record an animation into it. You do this by hitting the record button in the Animation window. While recording, any changes made to the GameObject will be recorded into the animation clip. (For example, you might move your GameObject). Any such change will create a key frame in the Animation timeline. The time point where key frame should be created can be changed.
Unity will interpolate the changes between two keyframes automatically.
However, there is also an animation curve which allows you to define how changes are applied between time points.
After you record animations you can define how transitions between different animations are made in the Animator Window.
unfortunably I am not really sure what your question is about?
For question this might be helpful:
https://www.youtube.com/watch?v=PuXUCX21jJU
Usually you have a Image File with the animation movements of your 2D Image object and using the "Sprite Editor" to cut them out for Unity.
You then add this Clip on a Animimation Component to be added to your "GameObject".
Since this is a "C#" question, maybe you want to know how to access this Compnent. The best is to use it in the "Init()" and add:
var anim = GetComponent();
Now you can use the "Animation" Component to play the configured Animation Clips.
I hope this helps you a little bit.

UI Canvas Image with UI Buttons

I have UI canvas image with 2 UI buttons. I set as background, that layer. But this layer overlaying my game! How do I it is behind everything?
I want set the second imagem as background.
I am using the UI Canvas because it automatically adjusts to any screen through the anchors.
-
No GameObject in your scene should be under Canvas unless the GameObject is part of the UI. The background image you want to use is not a UI. Your post shows that you only want it as a UI because Canvas automatically adjust the size to match the screen size.
How to fix this with code and without making that background texture part of the UI.
1.Remove/Delete the current Background and the Canvas Object for it. You don't need it.
2.Re-import the background image and make sure that its Texture Type is set to Sprite (2D and UI)
3.Drag it to the scene and rename it to Background. Now put it under Bee GameObject. Bee should now be the parent of the Background texture and the Background texture should be on top of Ground Object.
4.Create a script called BackGroundResizer and put the code below in it. Attach the script to the Background GameObject/Texture.
// Use this for initialization
void Start()
{
resizeSprite();
}
void resizeSprite()
{
SpriteRenderer bgSprite = GetComponent<SpriteRenderer>();
float screenHeight = Camera.main.orthographicSize * 2;
float screenWidth = screenHeight / Screen.height * Screen.width;
transform.localScale = new Vector3(screenWidth / bgSprite.sprite.bounds.size.x, screenHeight / bgSprite.sprite.bounds.size.y, 1);
}
This should solve your current problem for this post. Below describes how to properly setup a UI.
Use different Canvas to separate your UI and group them depending on when they are displayed. Then you can toggle the whole Canvas on/off. Your post before this post shows that you are using image as button and you have a different script attached to two images you are using as buttons. Use Buttons for buttons and image for non-clickable objects. Simple as that. So change those images to buttons.
You don't need the GameOver scene. A GameOverCanvas is fine.
The GameObjects in bold are the parent Objects(Canvas). The ones under that starts with '-' are the child GameObjects.
Step 1:
Create Canvas and name it MainMenuCanvas (First UI to display when game Loads).Create each child button and rename them as below(GameObject->UI->Button):
-playButton;
-settingsButton;
-exitGameButton;
Attach the MainMenuCanvas script to the MainMenuCanvas Object.
Step 2:
Create a Canvas and name it GameCanvas (Displayed during game).Create each child button and rename them as below(GameObject->UI->Button):
-pauseButton
-jumpButton
Attach the GameCanvas script to the GameCanvas Object.
Step 3:
Create a Canvas and name it PauseCanvas (Displayed when pause button is clicked).Create each child button and rename them as below(GameObject->UI->Button):
-resumeButton;
-backToMainMenuButton;
-settingsButton;
-exitGameButton;
Attach the PauseCanvas script to the PauseCanvas Object.
Step 4:
Create a Canvas and name it SettingsCanvas (Displayed when settings button is clicked).Create each child button and rename them as below(GameObject->UI->Button):
-backButton;
Attach the SettingsCanvas script to the SettingsCanvas Object.
Step 5:
Create a Canvas and name it GameOverCanvas (Displayed when Game is Over or player is killed).Create each child button and rename them as below(GameObject->UI->Button):
-playAgainButton;
-backToMainMenuButton;
-exitGameButton;
Attach the GameOverCanvas script to the GameOverCanvas Object.
Step 6:
In the Game scene, make sure that only GameCanvas is enabled. The rest of the canvas should be manually disabled.
Step 7:
In the Menu scene, make sure that only MainMenuCanvas is enabled. The rest of the canvas should be manually disabled.
Once you get this setup correctly, the UI code templates I provided should work. No more UI overlapping each other and you can easily add or remove features.
Your setup should look like the image below.
I recommend that you look into using a separate UI camera. This will allow you to draw only the UI to the second camera and not the Main Camera. You can then Draw that at whatever depth you want relative to everything else. To do this you will have to create another camera and set it's Culling Mask and Clear Flags to only draw the UI and not a skybox.
If you google 'UI camera Unity' there should be a lot more information on doing exactly what you want. This is a relatively common thing to do.

Animations on Mixamo not work

I downloaded 2 animations from Mixamo called Idle and Walk_Forward. I created my controller with blend tree and it worked fine. But the problem is when I press W button, the character only move a short distance then back up to the orginal place where he start "Idle". Someone told me to download animation with "In place" option. So I tried then had another problem: The character just play animation but not move forward. About my component on character, I created RigidBody with Use Gravity, and the animation and character is humanoid type. How can I make those animations work ?
If you are using an animation which animates in place then you'll have to add a characterController to make you're character actually move. The animation will only make it look like you'r player is moving. Here is an example of how to move your character.
Implement import of model settings and set "Animation Type as humanoid" in the Rig tab. Then press Apply. Now your animation would not repeat.
