Sprite Sheet 4x4
Toney Talbot
When I create a new Tileset, I simply enter the pixel dimension of each tile (hexes in this example, and they are all the same), and set the margin = 1 (around the edge of the sheet) and spacing = 1 (which you can see in this image). Works like a charm.
Note also: To my knowledge, once you create a New Tileset, if those settings in the image above are not correctly matching your sheet, you cannot change them inside Tiled. Instead, trash the New Tileset, adjust those settings to properly match your image sheet, and try again until the Tileset grid lands where you want it.
I am new to Tiled and I am not sure how to best handle sprite sheets with various sized sprites. I understand that I can load them individually via different files but I thought best practice was to keep them together on a single sprite sheet.
I am generating my sprite sheets with Blender and then touch them up with Asesprite. I really like this workflow and gives me my desired result. Now there is one problem. I would like to use multiple sprite sheets to animate one character, for example; running, walking. idle, and some attacks.
What I thought was perfect; using the animatedSprite and making my different animations with multiple sprite sheets and then use them in the animationTree. because I really would like to use the animationStateMachine
Is there a reason why I export 43 frames and the sprite sheet has only 32 frames?
Is it ignoring duplicated frames?
I need all of them because BabylonJs doesnt allow so much options at the time of setting up animations and I need each animation to be lineal.
One thing I have noticed on some sites is that they use one BIIIIIIIG image containing lots of little images, then use CSS background-position to define the coordinates of each image, rather than use individual images.
Recently I had a website with a lot of transparent gradients (white to trans, grey to trans) and some black and white on transparent images. By putting them all in a sprite and reducing the colors in the png to 8 I could get the sprite to be smaller in filesize than the original images (just... it was about a 0.5% saving). By reducing the number of HTTP requests from 10 to 1 though meant the site loaded faster (if measuring time from first connection to all data transferred).
When you load one large image, it contains only one of the different attributes that an image needs (color table, mime type etc ex: imagine if you're using a progressive jpg format, one spritesheet will allow the image to be scanned once, whereas many will decrease load time significantly) instead of having the same information in 100 different files, it will lessen the filesize in the big picture.
The pros far outweigh the cons in this method, the proof is that it has been taken up into use by so very many developers. If it were a terrible method, nobody would have picked it up and somebody would have already raised these issues when it was first put into use.
Google describes it here. Basically it should reduce page loading time. Every new connection initialization adds some delay. In some cases it can also reduce data transfer size and therefore also reduce page loading time. It is suitable for images that change rarely or all together (themes). Then browser can use cached image and needs to check only one file for changes not every image one by one.
Sprite sheets are a mess. Period. No need to sugar coat it. They present a massive step backwards in design technology, which probably explains why the only people who like using sprite sheets are old school game developers. Sprite sheets only have one redeeming quality, they are a little faster to load. Other than that, they are garbage. Not to mention a nightmare to set up.
In what world is it "acceptable" to have to include 500 lines of code just to run a simple walk cycle. Hopefully some clever guys will come up with a solution as simple as dragging a self contained, alpha-supporting video format such as flv, but that would also run on tablets...
If you feel like writing a massive list about how great sprites are, I can only wonder how boring your design job must be. The bottom line is that if a "tool" is making it harder for you to do things which should be easy, then it's not a good tool. Throw it away.
Most browsers will only download around 2 resources per domain in parallel, so if you serve up a lot of small images, the user has to wait for for around half that many HTTP request-response cycles. If you use a sprite, that's only one request and one response (albeit a bigger response).
If you have many images, the browser will need to download each and every one of them. Since the browser can only download a limited number of files simultaneously, this will take time. A single image will only tie one download slot allowing the page to render faster.
this is specially good for a lot of small images, because the browser only has to do an http request for all the images, and not hundreds of them. So you're web loads much faster on the client browser.
So I followed every instruction right and for some reason the sprite sheets arent showing any previews of itself and when it does manage to show a preview, none of my sprites are there and its just transparent. It says "Selected symbol is not in the sprite sheet" and yet for other projects it is working fine. (Screenshots ahead)
I got this problem too, and I think the source for me was having blank keyframes with filters on them. (they appear as frames with white dots on the timeline) I removed the effects on the frames in the properties window and it loaded the spritesheets like normal.
Every time I overwrite my sprite sheet with additional or updated sprites, I have to reattach the textures to all of my Animations and Sprite Renderers. How can I update a sprite sheet without affecting the sprites on that sheet which are already being used?
During the development of even a small game, hundreds of textures are being used. And new textures are being added and updated every day. This results in many hours spent reattaching textures which could otherwise be used being productive. What strategy can I use to prevent this?
I have a sprite sheet with 40 textures. All of its sprites are attached to their relative GameObjects. I decide I want to change the color of one of my sprites' hat. I go into gimp and load the sprite sheet. I change the color of the hat. I overwrite the old sprite sheet.
Back in Unity, all of the textures are no longer attached to their respective GameObjects. I go in and splice the sprite sheet again and manually reattach all of the textures. Then I decide I like the old hat better. I go back into gimp, change the sprite sheet, and am then forced to reattach all of the textures...again. There has to be a better way! (Also would like to be capable off adding new sprites in addition to editing old ones.)
Be sure you open the Sprite sheet from the path of the asset. You can achieve this either opening the sheet within the project window or going thru your documents to the asset folder of the project location.
I created a simple idle animation on the Spine animation software. Then I exported the animation into a spritesheet and I imported it to Unity. Then used sprite editor and split it up and then create the animation. The pviot point at the center x = .5, y = .5. All the images look like it got split correctly, but once I tested the animation it looks like some of the images shift ever so slightly as if they weren't centered. I am not sure if this was spine exporting it and like shifting the images just so slightly when combing it into a spritesheet or that the unity sprite editor wasnt able to slip it good. If I were to just export each image individually instead of creating a sprite sheet then the images are all centered when i create the animation with no shifting. I messed around with the settings on exporting scaling, stuff like that in Spine but nothing has helped. Anyone have an ideas?
The current workaround is to add a rectangle image behind your skeleton to force Spine to use it for the bounds calculation for all animations regardless of poses. You just have to make sure none of the poses go beyond that rectangle. Then make that rectangle transparent by changing its attachment or slot color, so that it's not visible on the exported frames themselves.
I know this is a bit of a necropost but I'm new to Spine and trying to simply export my animation to a sprite sheet to be used with Unity's Sprite Editor. Any chance you can point me in the right direction/offer a quick explanation?
Spine doesn't directly support exporting a packed sprite sheet, but you can export individual PNGs for a skeleton and its animation, which you can then import into Unity. Unity will create the sprite sheet for you based on these image sequences. For the Spine Editor side, you can find the docs here: Export - Spine User Guide: PNG
I like to make my sprite sheets tight, so I have never really used the offsets or padding. Padding, I believe, is if you add some blank space around your tiles in the sprite sheet, and I would assume you want that spacing to be regular around each tile. If you have 1 pixel padding on your sprite sheet, then put that there.
I have a case where I already erroneously imported my sprites. Now, I need to get the separated images from my sprite sheet. But when I slice and hit apply, I am not seeing multiple images in my project, just the same single image for my sprite sheet. Do you think I should reimport from scratch or is there another to solve this in your experience. Thank you!
Sprite sheets already exist since the first days of computer games.The idea is to use one big image that contains all animations of a character or items in a levelinstead of dealing with many single files.
The developers of game engines are aware of the wasted memory in the simple sprite sheets and started to optimize the space.The easiest way is to remove the transparency surrounding the sprite and shrink it to the bounding box.
