ex2D - the best 2D sprite solution for Unity [RELEASED]

hi jwu

Thanks for replying
Good work!

 

Thanks first of all. and I need to use multiple Atlus only for Main character. so in that case. its using(Player exSprite) one material. right. so only one draw call at one time right. right.

 

Quick Question. Will you guys going to release GUI support In near futur ?

 

One draw call for the character.

We are doing some GUI for our own project base on ex2D. We probably release these things in near future.

 

Hello jwu,

I am using ex2D and it is great product, but I have problem. maybe it is uv mapping.

I build Atlas (using default parameters) from 4 different solid color textures and 4 sprites from them, but all of them have problem 0.5 px from the beginning, u can see in attachment. also if it was not clear we where expecting to see no color leackage at the borders of the sprites. Is it a bug or am I doing something wrong? Picture is increased 4 times from default size.

I can send you unity package of this test if you wish.

Thanks

 

Hi mgebra,

I must check this by the texture you import. Can you send me these textures, let me confirm the problem in my PC. Thank you in advance!

 

We are working hard for the next version of ex2D --- v1.2.2 .

In this new version, we introduce a Layer Manager system. Here is a screen shot of it:



The layer editor provide an interface to help you organize game objects by layer. In the scene, the layer will eventually calculate as z position for each game object, this release you from sorting the draw order for the game. It is especially useful for a action game which the character and enemy are animated by skeleton! For more details about the new Layer System, read the documentation here: http://www.ex-dev.com/ex2d/wiki/doku.php?id=manual:advance:layer2d_usage

We also improve the performance in rendering sprites by using sprite manager. The whole changes of ex2D v1.2.2 can be found here:

New Features

• Add Rebuild Prefabs in Edit/ex2D/Command menu. (Help user update prefabs in project when atlas changes).
• Add New Layer System, exLayerMng, exLayer.

Changes

• Disable atlas texture Read/Write settings after atlas texture built
• Use exSpriteMng update sprites instead of updating all sprites in each LateUpdate function (it also longer the battery life and the device will not get too hot )
• Fix sprite animation play hidden sprite will show last frame at first.
• Change exSpriteAnimation.Play() to exSpriteAnimation.PlayDefault() so it will not conflict with Play(string) when setup animation event in animation view.
• Disable exSpriteAnimation when animation paused or stopped.
• Disable exSpriteAnimation when the game started but no default animation played.
• Remove exPlane.plane, instead we assume user working in XY coordinate space
• Remove exLayer2D, use new layer system exLayerMng instead of it.

Bug Fix

• Fix sprite animation trigger event that play current animation again has no effect.
• Fix SoftClip not update immediately when sprite postion changed.
• Fix sprite font line height calculate wrong when scaled
• Fix animation helper keep reporting error when upgrade ex2D.
• Fix spriteMng commit error when guiBorder is null
• Fix exScreenPosition, exViewportPosition not work with Perspective camera

The new version is ready and waiting for submit to the asset store. In the meantime, we are developing the new website and provide more solution for user to buy this product.

Since a lot of people asking buy the produce with source code in a higher price, we are now prepare two different solution for ex2D, the ex2D indie and ex2D pro. We also provide upgrade solution for ex2D indie user. These service will come up in the next few days.

The price will be adjust once we submit to the asset store, hurry up for you last chance! And thank you for your support and advice to help us improve ex2D better and better!

 

And still no chance to fix Asset Server issues and crashes on synching in this version?

 

Yes, we are going to make a big changes in v1.3.0, so Asset Server and crashes will be fixed in there. We also going to do a minimal fix for this problem in v1.2.3, which will at least prevent crashes and correctly sync the data.

 

I have another question,
In my Game the Background size is 6000 * 400. so I cut the whole image into 6 pieces and made them as 6 spirite objects. Then i put them in my game as one image. But the problem is the connecting margins of the sprites are visible when playing the game. They are not visible in the scene view(when player moves around margin area, margin is start to blinking as black line). I even set the filtering to Point Mode and Filtering as Clamp this help little bit but not really.

About layering management thing, it will be really good update for ex2d. I sufferd lots of problem with rendering order of ex sprites. right now im manually updates the depth. Im really wanted Layer Manager system.

 

Hi myprabath01,

To prevent black line and blinking, you need to set filter mode to Point in atlas texture (not the original).

 

Hi,
I've a problem with the custom resolution.
How can I fix sprite position when this option is enabled ?

 

Hello rineddy,

Can you tell me more about the custom resolution? Do you mean the custom size option in sprite? And what is the problem with fixing position of a sprite?

Thanks in advance.

 

Hi,

Would like to know whether this is possible, let say:

1. Create a series of images for walking. I only created walk images facing right.

2. So, I create an animation, and put this animation on the AnimatedSprite.

3. Now I have an animation walking towards right.

The question:

Let say, I created a script and attached to the AnimatedSprite. I want to detect if the user press right arrow key, I want the character to walk towards right (facing right of course), otherwise if the user press left arrow key, I want the character to walk towards left (facing left).

So, how can reuse the same animation (e.g. by flipping it), so that I can animate the walking animation which facing left with the same set of animation? via C# script. (The detecting key, direction, walking, moving the sprite I am able to achieve).

Or I have to create the animation (and the images) that facing left as well?


Thanks

 

Hi michaelkamms

You just need to call exSprite.HFlip() to flip the texture horizontally.

 

OK, I think i got the idea. Thanks for the prompt reply.

ex2D is a wonderful plugin!

Thanks

 

Hi, I am fairly new to ex-2d and I have watched both the tutorials you have in YouTube.
My problem is that I am using windows, and when I click at sprite animation editor, it only gives me "Please select a sprite animation clip", and nothing else.... no "Create", no other stuff than the one you have on the tutorial.

Please help

 

Hi decoy98,

The video in tutorial is an old version of ex2D. In the new version, the way to create atlas and sprite animation is changed in right click mouse in Project Window. For more details, you can read the documentation of them here:

http://www.ex-dev.com/ex2d/wiki/doku.php?id=manual:atlas_editor:create_and_edit_atlas

http://www.ex-dev.com/ex2d/wiki/doku.php?id=manual:sprite_anim_editor:create_sprite_anim_clip

 

ex2D v1.2.2 is now available in asset store. Check the first page for more details

We also upgrade our web page for selling the product in our web site directly

The new version of ex2D provides a new Layer System which can help you organize the z order of 2D object easily. Read this for more details

 

Hi , i try to play sprite animation but it`s not working ! i use this code :

 

Hi madhdi68,

The code you paste is correct. The problem is did you add this "ninja_run" animation in your exSpriteAnimation ? And does it use the name "ninja_run" in the list ?

 

Hi jwu,

I updated Ex2D and tried again to create and assign all from script. It works until I select the object. Before I select it, I can check the values of atlas and index and they seem ok. When I select the object, it clears itself. exSprite.atlas becomes null as soon as the object is selected.

The code is the same as the script I pasted some days ago with the correction you told me with exSpriteEditor.

If you want to test it, replace the previous OnGUI with this one.

Code (csharp):

1. void OnGUI()
2. {
3.     if( Event.current.type == EventType.DragExited )
4.     {
5.         Texture2D tex = DragAndDrop.objectReferences[0] as Texture2D;
6.         if( tex != null )
7.         {
8.             exSprite sprite = _ObjTest.GetComponent< exSprite >();
9.             exAtlasDB.ElementInfo elementInfo = exAtlasDB.GetElementInfo( exEditorHelper.AssetToGUID( tex ) );
10.             exSpriteEditor.UpdateAtlas( sprite, elementInfo );
11.             sprite.Build( tex );
12.         }
13.     }
14. }

Am I doing something something wrong or I there another bug ?

 

Hi jfmoulin,

I think we both miss to assign textureGUID for the sprite. So the correct code is:

Code (csharp):

1.  
2.     void OnGUI()
3.     {
4.         if ( Event.current.type == EventType.DragUpdated ) {
5.             DragAndDrop.visualMode = DragAndDropVisualMode.Copy;
6.         }
7.         else if( Event.current.type == EventType.DragPerform )
8.         {
9.  
10.             DragAndDrop.AcceptDrag();
11.  
12.             Texture2D tex = DragAndDrop.objectReferences[0] as Texture2D;
13.             if( tex != null )
14.             {
15.                 Debug.Log("yes");
16.                 exSprite sprite = _ObjTest.GetComponent< exSprite >();
17.                 exAtlasDB.ElementInfo elInfo = exAtlasDB.GetElementInfo( exEditorHelper.AssetToGUID(tex) );
18.                 exSpriteEditor.UpdateAtlas( sprite, elInfo );
19.                 sprite.textureGUID = exEditorHelper.AssetToGUID(tex);
20.                 sprite.Build(tex);
21.             }
22.         }
23.     }
24.  

What I add above is the line:

Code (csharp):

1.  
2.                 sprite.textureGUID = exEditorHelper.AssetToGUID(tex);
3.  

Enjoy!

 

Hi , i attach my project picture , i add animations but it`s not working

 

Hi mahdi68,

Looks good for your settings. So where is the script component you attached at? In the Player or in the SpriteObject? I can see you use Player as parent of SpriteObject. If you attach script in Player, then it will not play animation for SpriteObject. Otherwise, I can't figure out what is wrong here.

Can you send me a package of this issue ? Thanks in advance.

 

i added script to player ! i change it to SpriteObject and it`s work fine , thanks

 

Hi,

Is there a way to hide the red border for softclip during game play?

Thanks

 

@jwu

Yep, that was the missing part. It works now.

Thanks Jwu !

 

Hi michaelkamms,

The red border should hide while the game is playing, unless you enable the Draw Gizmos in the game I guess.

 

Sorry, my fault. I have Gizmo on... sorry...

 

Hi,

How is possible to create exSprite from directly c# script?
I have try something like this :

GameObject sprite_hex;
sprite_hex = new GameObject( "sand" );
sprite_hex.transform.Translate( 65, 0.5f, 100 );

exSprite sprite = sprite_hex.AddComponent<exSprite>();
sprite.SetSprite( sprite_atlas_hex, sprite_atlas_hex.GetIndexByName( "hex-sand" ) );

And i see GameObject in scene list but it's not showing on screen.

Please help. Thanks!

 

Hi warboss,

I've fix this bug. If you subscribe our Newsletter, you will receive the daily fix version including this. Thanks for your report!

 

Hi jwu,

Thanks for fast reply.

Actually after add this line of code :

sprite.ForceUpdateMesh( sprite.meshFilter.mesh );

Sprite start drawing ok. I don't know is't correct wise method for creating mesh this way for exSprite.
Also how is safely to destroy GameObject with exSprite that was created directly from code above.
Thanks

 

Hi warboss,

Yes, that is the line I added to fix the problem. You can just call GameObject.Destroy ( obj ); to destroy a GameObject with sprite component on it.

 

Hi, jwu, I know ex2D just 5 minutes ago. : ) But I am interested of ex2d and want to ask some question.

1. When will you release "2D Skeleton Animation Editor" ?
2. Can I use 1 GameObject to manage multiple sprites ? (since too many GameObjects are not good for performance.)
3. Can I download forever after I paid ? How does it work ? I will receive an email with URL link to download it ?

Thank you very much.

 

Hi donlien,

1. The 2D Skeleton Animation Editor still under developing and in a low priority, we are currently focus on v1.3.0 which will solve problem when working with Asset Server.

2. Well, you can use a GameObject control sprites, but one sprite component can only attach in one GameObject. BTW: I don't think the number of GameObject will cause performance problem if they are not have Script Component that use complex Update function. You are free to create 100-200 sprite objects in a scene if you draw them properly.

3. The Asset Store will make sure you have paid the plugin and helps you update to a new version. So don't worry about that.

Any questions, feel free to ask us.

 

Hello jwu,

I have just downloaded ex2D 1.2.2 and am trying out the new Layer editor

I have created 2 sprites in my scene, RedSprite and BlueSprite. Since they both have the same Z position (0) and I created RedSprite first, BlueSprite is drawn on top of RedSprite by default.
I have assigned an ExLayer script to both of them and ordered them in the Layer manager to draw RedSprite on top of BlueSprite (see screenshot).

When I start the game however, the layers do not seem to be applied correctly - BlueSprite is still drawn on top of RedSprite.
Once I click 'Update' (while the game is running), the issue is fixed, but only for the duration of the game.
Clicking 'Update' outside of game mode does not resolve this issue, it seems the layers are not correctly applied on startup of the game?
Am I missing something to make the sprites get sorted when the game is started?

Regards,
Tobias

 

Thank you for reply. : )

Re 2: I'd like to know if I create 200 sprites on iPhone 3GS, will it can still has performance of 40 ~ 60 FPS at least ? ( I remember it will slow down drop below 30 FPS if there are about over 150 game objects in the same time even only draw 2 polygons of every game object in my own test on iPhone 3GS. )

Re 3: I think I'd like to buy it on your web site http://www.ex-dev.com/ to save my money. It is reliable for re-downloading plugin, too, isn't it ? Can I get a download URL for update in future if I buy it from your web site ?

BTW, have you any plan to make some "trail" (moving like a ghost flying swaying with a transparent tail) or "laser" object to add into this plugin ?

 

Hi Tobias,

Do you re-assign the z position to the Red or Blue Sprite while the game running ? Can you send this package to me so that I can reproduce it in my machine.

Thanks in advance.

 

Hi donlien,

For 3GS, I think it can't afford that much sprite in a scene. The draw performance is relate with the number of the polygon and the draw calls of them. So you have to save both of them to get a good FPS in Unity3D.

You can buy it in our web store and still get download to a new update. The service we choose support it, so don't worry. But we recommend people using Unity Asset Store for better upgrade experience.

We didn't have plan to make trail or laser yet. But I will consider that, looks pretty good and reasonable.

 

Hi,

I'm upgrading to v 1.2.2 RC3 and found a bug with the layer manager. If you attempt to drag an object that does not already have an exLayer component into the layer manager editor window, ex2d will hang on a progress bar. At the very least, it should reject the object, but it would be nicer if it automatically (and recursively) added the component to the object.

Thanks!

 

Hello CapnCromulent,

It will add the layer component to a object that don't have it when dragging into layer manager. So it could be a bug for this. Can you give me a unity-package with this problem? Thanks in advance.

 

I sent a email with a sample package and repro steps to support@ex-dev.com. I couldn't include my game assets, but I can still reproduce the bug with the supplied object hierarchy.

Please let me know if you need anything else.

 

Hi Jwu,

Also it's will be great to have in ex2d feature like this :

Polygon collider editor - Set up polygon colliders quickly and efficiently (see 2d toolkit)

Thanks!

 

Man, thank you so much Wu Jie!!!

 

Hi warboss,

Actually, we have put it in our TODO list. But would be done after v1.3.0 comes out.

 

Great! Thanks!

 

Also for c# scripting this code :

Code (csharp):

1.                    
2. sprite_hex = Instantiate( sprite_animation_prefab ) as GameObject;
3.  
4. exSprite sprite = sprite_hex.GetComponent<exSprite>();
5. sprite.SetSprite( hex_animation.frameInfos[0].atlas, hex_animation.frameInfos[0].index );
6. sprite.ForceUpdateMesh( sprite.meshFilter.mesh );
7.  
8. sprite_hex.AddComponent<exCollisionHelper>();
9. exCollisionHelper collision = sprite.collisionHelper;
10. collision.AddBoxCollider();
11.  
12. exSpriteAnimation sprite_animation = sprite_hex.GetComponent<exSpriteAnimation>();
13. sprite_animation.AddAnimation( hex_animation );
14. sprite_animation.defaultAnimation = hex_animation;
15. sprite_animation.PlayDefault();

Have a problem with BoxCollider updated for animation. Especially Z offset is a different for the same gameobject without animation and Physics.Raycast don't have a hit.

But after modify to this :

Code (csharp):

1.  
2. sprite_hex.AddComponent<exCollisionHelper>();
3. exCollisionHelper collision = sprite.collisionHelper;
4. collision.AddBoxCollider();
5.  
6. collision.autoLength = false;
7. collision.autoResizeCollision = false;

Z offset becomes the same to gameobject without animation and Physics.Raycast have a hit.

 

Hi again wu jie, I was wondering what code I can write to play a running animation when I press the left or right arrow button?

 

Im gettings this Error when i select ex2d Prefab. Tried many times. No solution. Using Ex2d 1.2.2 and Unity pro 3.4.2
