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
