Heya folks, behind the scenes I’ve been working on the next version of the undo/redo system along with new data layouts to make batching (for rendering) faster.

Undo/redo is one of the areas we’ve had serious lag before when working with large slabs of tiles. When looking at the code it was understandable why, however, there are interesting complexities to the system when you have multiple people adding and deleting tiles concurrently.

For the last two days, I’ve been working on a new design for the system. When doing we also have to make sure that the data layout we choose for this doesn’t make it slow to perform frequent tasks like rendering.

This is one of the bits I love with this job, sitting down with a pen and paper and just wrestling with a design.

I think I have something now but I’m not going to put it here yet as it needs some further validation. What I’ll do next is code a small prototype so I can see the properties of the system more clearly.

More details on that in the coming days :)

Peace.

Hello folks,

Research continues and, for now, that isn’t giving me much to show so I took an hour out to explore a requested feature: NDI Support.

NDI is a standard that lets applications deliver video streams via a local area network. For us, we are interested in being able to take these video feeds and use them in TaleSpire. This originally came up as a request from the community as it is apparently a popular way for streamers to integrate video (such as their player’s skype chat) into their streams.

It sounded cool and luckily where is already a Unity package available for working with NDI. It worked like a charm so HUGE props to keijiro for that great work.

This was a very limited test but it is encouraging. We would need to do a bunch more work to be comfortable shipping this and we wouldnt want to mess with the roadmap we have promised the Kickstarter backers. All that said this was a fun test and one I’m excited to revisit if it makes sense later on.

That’s all for now

Peace!

Another short dev log while we are still in the Kickstarter campaign.

Recently I’ve carried on studying. It looks like the hybrid renderer doesn’t handle per-instance data yet (which is mad) so we won’t be able to use that yet. This means we will probably want to avoid Unity’s ECS for now and just work with something similar but custom until that stack matures. This is no real issue as although we will have to do a little bit of tooling work when we need insight we do have experience in that.

Ree has always been the lead dev when working with graphics and shaders in Unity as he has many years of experience beyond me. I (Baggers) come with a decent amount from the GL side though so I’ve spent some time getting more used to hlsl and tooling we’ve been using. It’s fun, a lot of things are set up for you of course so I’m not sure (without the scriptable rendering pipeline) how one really packs data or does very custom stuff, but there’s plenty of time to learn that and the team has bags of experience I can lean on. This is really just making sure we are cross skilled enough that we don’t bottleneck each other too much (although when it comes to content creation I’m hopeless :D)

That’s all for today,

Peace

A quick update for today.

The day was mostly spent reading up on the new Unity.Physics package to see if it will be viable for use in TaleSpire. It is a preview package and that does come with a level of risk, however we only use the currently physics system for dice and for casting rays against for tools. This means our requirements are very simple and even at it’s current state the package has what we would need, assuming of course that it works as documented.

It certainly has some surprising aspects such as how it’s not framerate independent by default, but handling that seems to be easy enough.

Peace

Heya folks, yesterday and today I have spent getting familiar with Unity’s Job Systems and new ECS.

I’ve written toy ECS’ before and am currently working on a little optimizing compiler for querying table data so a lot of things were very familiar. The bulk of the video and prose content for Unity’s new systems is focused on the fact that the new thing is ‘different, but don’t worry it’s fast and not that hard’ etc, etc. As I’m already sold on the premise this is nice but of limited here. Beyond that, you better be comfortable reading other people’s code :p

The best resource so far has been the ECS Samples. It’s a small of samples evolving a piece of code from a foreach on the main thread, through different flavors of jobified tasks. One of the biggest advantages of the code is just seeing what is still in use. If you glanced at the cheatsheet you’d be missing certain things (like sync points).

The reference docs are passable but there are plenty of things where the description of a method is the name. When I hit walls in C# I often read Mono’s source to get an idea of what to expect, but naturally many of the things in the new ECS are either proprietary or are in c++ code I can’t reach easily so those missing doc-strings become a pain point.

Given that, in TaleSpire, we load most assets dynamically I’d like to avoid having to use the Entity conversion routines on load of each asset, I’m fine with running them in TaleSpire and serializing something useful, but I’m not sure how we prefabs play with ECS entities at this stage. I’d be very surprised if Unity’s mega-city demo was using conversion routines so I’m sure there is still more to understand here. Also the lack of documentation around the Hybrid.Renderer is a pain in the proverbials, I’d really like to look into zone culling in TaleSpire to potentially improve rendering performance but information seems scarce here. I’m sure it’s all in the mega-city demo but that doesn’t feel like the best introductory material to be using.

Regardless, between the samples and these docs, I’m making decent enough progress. We’ll definitely be using this in TaleSpire and I’ll have this under my belt well before the campaign ends.

Peace

Let’s get back into the swing of these!

During the Kickstarter I’m using any free time I have to study and make little systems to get familiar with systems we may end up using

Today I’ve mainly been getting familiar with blittable types. The reason for this is that Unity’s DOTS primarily operates on them.

I got interested in how easy it would be to de/serialize such data, given these types can have precise memory layouts specified for them. The that end I was making little BinaryWriters and readers that had Write methods that could take any blittable type or array of blittables and handle them correctly.

I’m going to make a dump of some useful links as most of the stuff I was doing was simple enough, but was a good exercise for familiarity. It was the first time I’ve significant use of pointers in c# and it was a very simple and unsurprising experience.

The first handy thing was that the unmanaged constraint is available. Whilst unmanaged types are not the same as blittable types there is a useful overlap. Using this allows us to have signatures like unsafe void Foo<T>(T value) where T : unmanaged. Also note that sizeof is defined to work on unmanaged types. It was very easy to write generic methods doing useful stuff with c#, I’m please with it so far.

• Scoped GC pin
• Heap allocate, check out all of Marshal, it’s pretty handy
• more info on blittables
• create a struct from data referenced by pointer
• You can explicitly cast typed pointers to IntPtr
• Unsafe seems like a handy class until you see that it’s not implemented in mono
• But then you find UnsafeUtility in Unity itself and it’s way better. memcpy, malloc etc are all there

The big disappointment of the day is how quickly one ends up having to reinvent the wheel as most Streams, Buffers, Writers, etc, never expose their buffer or provide overloads taking IntPtr. The more you poke to work around this the more it feels like you should just make your own. It’s not ideal. Saying that, I have spent most of today in dotnet code rather than Unity’s so I do still need to see what is there.

Until tomorrow, Ciao.

So here we are! The clock ticks and, baring any disaster, in the next 18 hours the Kickstarter will go live.

We are currently beavering away shining edges and triple checking wording.

It’s an odd feeling to be this close to finding out the world makes of this but it’s a privilege to be here.

Thank you to everyone that showed us that they were interested in this. Thank you to the alpha testers who delved deep and proved the limitations of the systems And thank you to you for reading these little posts.

The new day is upon us, The gates are soon to open, Let us see what is on the other side

Warmest Regards,

Dwarf, Baggers & Ree (The rather sleepy Bouncyrock crew)

Not really a dev log as right now there’s not a whole lot of dev going on. I’ve been just sitting writing an rewriting bits of the kickstarter page. It’s an odd feeling as I flit between thinking ‘ah your thinking about it too hard’ and thinking ‘man this kickstarter decides whether I have to refresh my CV soon’. Heavy.

It’s odd writing this when there isn’t much to report. Assets for the trailer have been made, the trailer itself is going well. Really I’m writing as it feels weird going a few days without reporting the latest to you.

We’ll be letting you know the kickstarter date one week before it happens.. which is soon.

Peace folks

Heya all, time for a quick behind the scenes again.

Those who have been keeping count since the dev stream will know that we are only a couple of weeks to go before we should be doing our kickstarter. We really need to focus on this so we will be pretty much stopping updates to the game for the next couple of weeks. I’m going to get the ‘duplicate board’ feature shipped this weekend and then I hope to fit in some bugfixes, but I think this is what we need to do to make sure we get everything done.

Other than that I finished v1 of the ‘duplicate board’ feature mentioned above. It’s a little rough around the edges but nothing not acceptable for an alpha. We just need to make an icon for that now and it’s ready to ship.

Not much more to say other than thank-you once again for caring so much about our little game.

We’ll do our best.

I was too tired to writeup last night’s dev log so here it is a little late.

I really want to get a user visible feature out this week so I implemented ‘duplicate board’. This will let you click on an icon in the board panel and duplicate the chosen board. This will be handy for a lot of cases but I love the idea of making a town, copying it and then destroying the town for the players to visit again after the calamity.

The hard parts had been researched or implemented when I was looking into the S3 part of cleaning up old board files. All that was left to do was write the database queries and expose it to the game itself.

With the core feature now working I just need to do cleanup and handle the fact that it currently doesnt copy the board description (an easy fix).

Back later today with more news
