Unity Scene Management

Hello guys this is Vivek Sharma and welcome to yet another Unity tutorial on C Sharp Content.com

In this video we will be learning about scene management and we will be creating a restart screen for our game

So without wasting any further time let's get started. So to begin with let's go to our pause menu and create a new button to restart our game

To do that I'm just going to copy the resume button. I'm going to change the font. I'm going to rename the button and I will remove this function

Now let's go to our scripts folder and create a new script and rename is add load scene

Let's double click on it to open this up. First of all, we will be deleting the start and update method from here

And then we will have to use another namespace called unityengine.scenemanagement. Using scene management, we can load different scenes

Now let's create a new public function called load screen, which takes a string as a parameter

which is going to be the name of the scene you want to load. Inside this, we just have to write scene manager dot load scene

and it takes the name of the scene you want to load as a parameter. Now let's get back to Unity

Go to Canvas. Click on add component and let's add the load scene script to our Canvas

Now click on our restart button. Go to the inspector panel and on click event

Let's add the function we just created. That is load scene script load scene

Perfect. Now over here we have an exposed string field in which we have to enter the name of the

scene we want to load. Let's write game scene into it. Let's go back to assets panel

Click on the scenes folder and rename the sample scene to the game scene

Now let's hit play, pause the game and click on restart button to restart the scene and

also get ready for a new problem So over here as you can see our dinosaur is not moving The reason being when we paused our game we set the time equal to 0 and when we restarted it we haven changed the time scale to 1 again

So to do that let's go back to our load scene script and over here let's write time.timescale

equal to 1 and it should work now. Let's get back to unity

Let's hit play and as we can see everything is working properly

Now let's quickly create a restart screen as well which shows up whenever the game ends

To do that go to canvas, create an empty game object, call it game over menu, inside it create

an image which we will be using as a background, now create a text and just write whatever

you want to write, game over UDIT whatever you wish, I will be using UDIT and then quickly

create a new button, change its size, change its font and rename it to restart button and

Then as we done earlier, assign the loadScene function to this button

Now let's go to our dino script. Let's create a public game object and call it gameOverScreen

Now go to the killDino function and just write gameOverScreen.setActive equal to true

That's it. Let's get back to Unity now. Click on the Dino Player. Go to the dino script

Over here we have got an exposed field for our gameOverScreen. Drag the gameOver menu from hierarchy panel to this exposed field

let's hit play. So now as you can see whenever our dino dies we get this restart screen and by

clicking on restart button we can restart the game. Okay so that's it for this video and probably

that's it for this game development series as well. I hope you guys liked this series and also

have learned something. If you guys have any doubts related to this series or related to anything
