  • Hi! My name is Gustavo Carvalho from Contra Labs

  • And this is how to make sprite animations with Unity 4.3

  • Using 2D native development

  • So, let's get started

  • Let's create a new project

  • I will make it "Animation Sprite 2D"

  • And here I will use nothing of this

  • But I will set up defaults for 2D

  • And "Create Project"

  • So, now we have this 2D option over here

  • Where we can see the scene in a 2D way

  • We have our camera, which must be set to 'orthographic'

  • Because you are dealing with 2D

  • Let's put a new sprite here

  • Unity 4.3 has this new kind of object called "Sprite"

  • Which contains the "Sprite Renderer"

  • Now we must create the images that will be used by our sprites

  • Let's create a folder called "Sprites" and put our sprites there

  • We can put the sprites separately or we can use a sprite sheet, like this

  • I will use this sprite sheet over here, let's make it into sprites folder

  • This is a kind of "Sprite"

  • The Sprite Mode is "Multiple" because I'm using a sprite sheet

  • And I can open the Sprite Editor to choose each one of the sprites I will use

  • So, before this I got this warning telling me that if I use a compressed texture

  • it will give imperfect results

  • So I will change the mode from "Compressed" to "Truecolor"

  • And Filter Mode I will change it to "Point"

  • If you are a beginner probably you want to use this as well

  • But if you are advanced you can choose better your configurations

  • So now open you Sprite Editor

  • Let's choose here...

  • Still got this warning because I think I did not apply this

  • I can open the editor again and slice it automatically using the automatic mode

  • I can use Minimum Size of 10 pixels because I know that every image I have

  • Is at least 10 pixels wider or taller

  • And the Pivot point I will use the bottom

  • I got this sliced and here I have all my images separately one by one

  • I can edit the options of each one, move the pivot or size

  • The pivot is this little ball, I can put whatever I want

  • I will leave at the bottom

  • "Apply" and now I have each one of the images separately

  • Now all I have to do is select my sprite object

  • That I created here and move the selected animation frame that I want

  • So for now I want it to walk so I will select this sprites and move it

  • To animation screen

  • I will put a name for my animation - Walking

  • And I will save it in a new folder called Animations

  • Save it. If you don't have the Animation window you can open it in Window -> Animation

  • So now you have this.

  • So if you go to you scene view you can see your sprite over here

  • And if you play it, it is animating but it is too fast, so you can

  • adjust the speed of animation to 12 and now looks better

  • And that is the way you do sprite animation in Unity

  • If you don't have a sprite sheet like this you could use separated images

  • It work in the same way, just select the images and drag and you have the animation done

  • But, how you can do separated animation?

  • If you go here in Animations (folder) it created an Animator called "New Sprite"

  • Which controls the animations and we have this specific animation which controls the walking

  • Now, if you go here and create a new animation (New Clip)

  • Let's say... "Running"

  • I will save it here as well

  • Now I have our Running animation and will configure this

  • running animation to use this sprites over here

  • So now i have a running animation and I have a walk animation

  • Walking and running

  • Here again I will change the speed to 12

  • And now it looks better

  • But, how can I change from one animation to another?

  • If I open here the New Sprite it will open a Animator window

  • And as you can see we have a Running and a Walking state

  • So the start state or the default state is that orange one

  • And from here I can choose to go to other states of animation

  • The way I can do this is make a transition and I have to configure

  • what makes this transition, what conditions trigger the transition

  • Now I only have this condition, "Exit time", so when this first animation is done

  • it goes to the next animation. But if I use some parameter here

  • I could create any parameter here

  • For exemple, "StartRunning", so now that I have this parameter I can go into the code

  • And say that animator.SetParameter("StartRunning", true);

  • So when the code tells the animator that StartRunning is true, then the transition will happen

  • But for now I will just use the Exit Time

  • But let's suppose I don't want the Walking running only once, I want it run twice

  • So after it run twice the character can "Running"

  • So let's test it to see if it is working or not

  • So now, as you can see, it is running, but I didn't see the transition

  • Let's start over. I think the transition from walking is too fast

  • But if you go really slow you can see it starting in walking and then

  • Moves to Running

  • And that it. A simple way to do sprite animations with Unity 4.3

  • Bye
