Cours 1 sur 5 dans Specialization Game Design and Development

If you love games and want to learn how to make them, then this course will start you down that path. Making games is a creative and technical art form. In this course you will familiarize yourself with the tools and practices of game development. You will get started developing your own videogames using the industry standard game development tools, including the Unity3D game engine and C#. At the end of the course you will have completed three hands-on projects and will be able to leverage an array of game development techniques to create your own basic games. This course is for individuals interested in becoming a game designer, game artist, or game programmer.

À partir de la leçon

Designing and Coding Gameplay Systems

Now, don't get scared, but games need code. Code is the canvas upon which game systems are painted. However, that doesn't mean you need to be a C# ninja. In this module, you will start to learn the ins-and-outs of programming C# in Unity. You will apply this knowledge to build a first person shooter game, called Box Shooter. By the end of the module, you will have the tools to begin to develop your own custom games!

In this video we'll set up our camera to behave and

control as we would expect in a first-person shooter game.

Our objectives will be to get the camera to follow the player and

respond to mouse input.la We'll also apply a number of rendering and

image effects to the camera including a skybox, contrasts, and bloom effect.

And we'll add our game music to the camera.

So how do we make the camera follow the player?

Given this is a first-person game, it probably makes the most sense to make

the camera a child of the player game object.

So let's go ahead and move the camera, so let me do a top down view.

And we can look at the relationship of the camera right now.

And it's a little ways away in the Z direction.

So it's negative 10 where the player is at 0.

So let me move it to 0, so it's right on the player.

And once again, we can look at it now.

You can see that it's quite a ways above the player.

So let me move it down.

I can visually move it here in the editor, down, or I could just do it numerically.

So through play, I wanna put it right at the top of the head.

The head is, the player is 2 meters high, so I'm gonna set it at 2.1.

So the camera will be right there mounted sort of to the top of the player.

So now that I got my camera positioned properly,

I'm gonna make it a child of the player.

So let me just drag the Main Camera right into the player.

And boom, we've got it as a child.

So let's go ahead and play to test this out.

So now when I move the player using the WASD keys, forward and back, left and

right, you can see the camera moves right along with it as you would expect.

So the other thing that would be nice is the ability to actually look around using

the mouse.

So let me hit Stop.

And I've included a script called MouseLooker,

which you attach actually to the player.

So let's go to the Player, click Add Component, go down to Scripts, and

choose Mouse Looker.

The script was adapted from a script provided with the standard assets.

It will change which way the player is facing and rotate the camera up and

down based on the mouse input.

So let's go ahead and try that out.

So hit Play.

So you can see, I can move my mouse up and down.

As I spin, it's actually rotating my player.

And of course I continue to use the W,S,A, and D.

So I've got pretty much a standard sort of first-person control now on my character.

So the MouseLooker script also locks the mouse to the middle of the screen and

makes it invisible.

If you press the Esc key on the keyboard, you can get the mouse cursor back.

You'll need to do this to be able to click on the Play button in the Unity editor

to stop playing.

So let me go ahead and hit Esc.

Now I've got my mouse cursor back.

I can go up and hit Stop.

The MouseLooker script is a fairly complex script, so

for now we won't do a code walkthrough.

But you're welcome to take a look at it if you so choose.

So while we're working on the camera, let's improve the visuals that the camera

is producing, starting with adding a Skybox.

In our first project, we added a Skybox through the lighting window,

which of course is under window, lighting.

And this is where it defines the Skybox,

this default Skybox that we're seeing with the sky and the moon and so forth.

So we can change the Skybox there, but

you could also change the Skybox on an individual camera.

So perhaps in your game, maybe you have multiple cameras and

you want them to have different Skyboxes for example.

So let me do it the other way for purposes of example.

So I will go ahead and close lighting and camera.

Go down to rendering, and I'm going to add a component.

Go down to rendering and notice there is a Skybox component that I can add.

And it just takes a material.

So I've actually got the Skybox material created.

Let me click on that.

You can see it is a standard Skybox,

a six sided Skybox like we saw in the first project.

And it's just got a grid texture in all six sides.

So back on the Camera, let's go ahead and drag that material onto the custom Skybox.

And down here on the scene view, you can see the change is reflected.

Now when you apply it to a Camera, you're gonna see it in the Game view, but

it's not gonna change In the scene view.

So we still see that default Skybox in the scene view.

So if you wanted to get rid of that we could go to the lighting window,

and hit the target for the Skybox and then maybe select none as an example.

And as you can see it just got rid of the Skybox in the scene view.

There are a number of image effects that we can enhance the look of what is

rendered on the camera.

Let's apply some of the image effects.

Now the image effects came in through the effects standard assets that were included

with that package we brought in, so you can see effects and

then image effects here.

But, usually these scripts and

other things are mapped right into the Unity interface.

So on the camera, let me go ahead and click Add Component.

You can see if I scroll down there's an image effects option here.

Let me select that.

And we're gonna apply two different image effects starting with contrast enhance.

So this is under color adjustments.

And we'll select contrast enhance.

And you can see the effect takes place immediately in the game view.

So if I turn this off and back on,

you can see it's just sort of brightening up the world a little bit.

I'm gonna make it a little bit more intense so the intensity is .5.

Let me go ahead and move that up to one.

That's just giving our world a little more of a Tronish feel, if that's a word.

I'm gonna go ahead and add an additional component.

Once again, go down to image effects, and I'm gonna do bloom and glow.

And I'm gonna choose the bloom effect.

This has got a lot of different parameters.

I'm just gonna leave it at mostly the defaults.

I'm just gonna change the bloom intensity from .5 to 2.

And if I click this on and

off you can see the effect that that bloom intensity has over the contract enhance.

Okay, I'm going to go ahead and close these up.

And we also want to have our background music playing on our camera because once

again the camera has the audio listener, and

the audio listener goes wherever the camera goes.

So, let's go ahead and add an audio source.

So I will Add Component, Audio, pick Audio Source.

I need to specify the Audio Clip.

I provided a number of audio clips that we can use for

this project including background music.

Let's go ahead and drop that on audio clip.

And for me, I'm gonna change the volume down to 0.25 so this isn't too loud.

You can set the volume as you see fit.

I'm also gonna change the pitch, so the pitch is typically 1.

I'm gonna make the pitch a little bit higher,

which'll just make the music sound a little bit more upbeat.

So I'll change it to 1.2.

And let's go ahead and play to see the result.

[MUSIC]

So we can walk around.

We can hear the music playing.

We've got this enhanced view of our camera with the Skybox,

and the contrast enhanced, and the bloom.

Notice as I look down, you can see a little bit of that capsule collider.

So we wanna get rid of that.

We don't wanna actually see our player, and we probably don't want the shadow,

either, for our player.

So once again, to get out of Play mode, I hit Escape.

I get my mouse cursor back, and I can go up and hit Play to stop playing.

So let me go to the Player, and I'm gonna turn off the Mesh Renderer.

So the Mesh Renderer is what actually renders the game object, so

I can turn that off.

Notice here in my scene view we can still see the capsule collider.

We still want the collider to exist.

If I hit Play again you can see I no longer have a shadow.

I no longer can see the capsule as I look down, but

it is actually keeping me within the confines of these bumpers.

Let me go ahead and stop.

Now that I have my Player set up I want to make it into a prefab.

So let me go ahead and drag Player into the prefab folder.

And it brings the camera ride along as the child of the player.

And let's go ahead and save our scene.

>> In the next video we'll set up the projectile that we'll shoot in our game.
