SpriteStack - Animated soldier breakdown

3 Sep, 2021

Ahoy!

I've got back to working on animations and I would like to share some results created with the new system and highlight a few features specific to it's workflow.

How does the scene look?

Fortunately these goofy eyeballs disappear at the resolution we are going to render at.

Keyframes

This is the animation sheet of the muzzle flash sprite alone. As you can see it consists of just 3 animation steps. SpriteStack works by fluently interpolating between keyframes - contrary to frame-by-frame animation this allows you to export as many final spritesheet frames as your game needs.

The flagship feature is that this system is designed to work well with spritesheets - jumping between frames and playing them in any direction is absolutely a trivial task in SpriteStack and you will never feel like they have been forcefully added to a 3D software.

Micro delays

One of the problems with such approach is that keyframe data is aligned to the grid. Let's say I want to shoot 6 bullets but there is only ONE data frame to accomodate them. To solve that problem I have added delay property that simply delays execution of all animations of that object by fractions of a frame. Both left and right animation consists of the same animation blocks - the only difference are the micro delays added.

Easing

Animation dynamics is based on making curves out of famous Robert Penner's easing functions. Here I have applied an easing curve to the rotation to give the emphasize the recoil.

That's how the curve looks like - it basically makes the guy go back and forth three times.

Thanks

I know it doesn't explain too much about animating stuff in SpriteStack but that's the job that manual and tutorial will do. Hopefully you got a notion of what's possible and now you are getting ideas for your own animations. It's far from done but I am leaving it as is because I have promised you to release the renderer alone so you can export still objects with SpriteStack look'n'feel.

I post micro updates on Twitter
Also there is a Discord community gathering up[discord.gg].
The model I am using comes from this free assets pack by Maxparata[maxparata.itch.io]

Aa an extra - since SpriteStack is a palette based software it took me about 5 minutes to recolor the sprites.

Thank you for supporting my work ❤️

Materials

New material system that lets you attach a material to the color index.

Spritesheets

Spritesheets are now an important part of a scene. One of many usages would be using them as an animated wall - for example sliding doors. SpriteStack allows you to control spritesheet animation in a detail with ease.

Library

Collect pieces that you would like to reuse among your projects and quickly drag-and-drop them in the scene.

New rendering engine

All new rendering engine with multitude of effects.

Why so late?

The year 2020 was really hard for me and for family matters I had very limited time to work on anything. Despite of that even by little steps I kept SpriteStack going. This unfortunate time combined with the number of features dependant on each other made my work look like an abandonware and I've decided to distance from social media to avoid depression. Now that everything is back to semi-normal I want to gain your trust once again and ask you to help me funding the last few months I need to finish this app.

Thank you.

Upcoming Update / 2019

25 Nov, 2019

Ahoy there. I have just realized that most of you might not follow me on twitter (@rezoner) where I post updates almost every day and from your perspective app may look abandoned which is as far from truth as possible.

For the last 3 months I have been working on a HUGE update that will improve a lot of things and overall workflow. I won't list all the changes but a few game changing features.

1. The heart of studio is now the animator/composer window where you can manage scenes and put multiple objects instead of one spritestack.

2. Asset library will let you build up your workshop with reusable parts that you may drag and drop on the project to speed up your creative process.

3. Animation panel has been reworked from the ground and it's now one of the more pleasant animation approaches I've personally every used.

There are also tons of minor changes that I will go through on the launch day.

Please forgive me that I am not very active on forum and community hub but it's really a daunting task for one man - especially a father of two. I've decided that it's better if I put my time in development although rest assured that I read EVERY single post and bug report and I will approach it sooner or later.

Thank you for supporting my work.
