Long have we waited.

We have a lot to talk about in this post so feel free to scroll down and read about the subjects that matter most to you.

Overall performance gains

Baking our vehicles has always been about optimizing the result. We are glad to have found additional ways to optimize our vehicles even more. Especially for highly detailed vehicles where a lot of pipes, plates and shapes can be found.

Fewer objects

First we found a way to remove pipe, plate and shape objects after baking the vehicle. Reducing the amount of objects means that rotating or moving these vehicle pieces has much better performance.

This example went from 432 objects to 3379 objects removed:

Fewer center of gravity points

We were also able to combine center of gravity points in a better way than before. Fewer center of gravity points means less computation is needed in real time. Again giving the most performance gain on detailed vehicles.

Here we went from 711 CoG points to just 8:

Smoother shader

We also took a look at the vehicle shader and found that it was doing some unnecessary things. So we simplified it and can see a significant reduction on the GPU load whilst looking at a vehicle.

Lightweight network IDs

And finally we went over the networking pipeline and were able to reduce the size of IDs sent with each network package. While this give a light performance gain on its own it does reduce network traffic a lot.

Voxel collision

Colliders play a big role in the handling and performance of your vehicle. Up until now the builder has been adding colliders for each part, pipe, plate or shape. As you can imagine for high detailed vehicles this results in loads and loads of colliders while this does give a decent approximation of your vehicle shape it is not so good on performance

So for this update, we introduce voxel collision. Voxel collision slices your vehicle in small pieces and adds colliders accordingly, resulting in fewer colliders in most cases while still providing a decent approximation of your vehicle shape.

We provided you with the choice between object collision vs voxel collision found in the utility bar. When we test our vehicle, we can now see how many colliders have been built for comparison reasons.

Weapons

Aah weapons... yes

We knew fixing weapons was an absolute must for this update... or else!

So looking at the code we saw a lot of issues. First, the system was so complex that our noodles could not make sense of it. We noticed that the teams system responsible for 70% of the complexity accounted for almost 0% gameplay since we never really use teams, except for that one time... maybe... So we removed the teams system and were left with something we could actually fix.

Remembering how damage used to be, the biggest issues are that we don't have per-part based damage, that we don't get to see damage, HP and armor feedback, and that gunner seats for other players are basically useless as the gunner seat lags behind due to ownership of the vehicle. There is more to improve but these outline the most prominent sucky parts of our damage system.

Damage and armor feedback

To give user feedback we now show damage and armor on the hitmarker whenever we make a hit.

HP feedback

Whenever we hit a vehicle we get to see an HP bar showing the remaining health of the vehicle. Know that damage is still split per vehicle piece, meaning not every hit will reduce the overall HP of the vehicle and the HP bar doesn't have to be fully depleted for a vehicle to be destroyed beyond the point of working.

Gunner seats

To fix the gunner seat issue we had to introduce a new wire type. From now on each weapon has to be linked to a seat using the weapon wire.

Linking the wire with a seat makes the weapon respond instantly to the player that is in that seat regardless of who owns the vehicle at this time. It also allow the weapon to know which player is actually doing the damage.

Overall weapons now rotate smoothly for non vehicle owners if it's welded onto a weapon mount or hemi servo, using the vector wire as input.

Tweaking damage on servers

Damage can now be tweaked via server settings. we can set damage and armor multipliers and we can cap the armor so it won't go above a certain value.

Known issues

While the damage system has been improved, some issues still remain that we can't fix right away. For example, tweaking the HP and armor coefficients requires us to run the system in a natural environment looking at all sorts of vehicles. So don't expect the damage to be tweaked perfectly yet, we will tweak the numbers as we go via the server settings, we will see what works best and provide updates as we go.

While the damage system has been improved there is still more to do like per-part based damage, missiles and bombs etc... We will dive more into weapons in future updates.

Christmas

One of our beloved community members Being Bright started a snow mod a while ago. We were looking for something to do for Christmas, while looking at his mod we saw a perfect match. We contacted Being Bright right away and improved the mod where needed. This mod will automatically activate between Nov and Feb, bringing snow to our world.

Vector Math Box

For our Math Heads we've added a "Vector Math Box" containing all the vector operations a proper Math Head would want. We can also convert from float wires to vector wires and back using this box:

Mod versioning

Mods now live in the current lua version folder, found at userdata/lua/ /... This means that you will have to move your mods to this new folder. A readme.txt file can be found in userdata/lua telling you what to do with your mods. you will also see a chat message giving you a warning that mods need to be moved, triggered only when you have mods installed and no mods are found at the new location.

Homebrew Devkit

Devkit? What's a devkit? Well, simply put, a devkit is a bag of tools that helps you develop certain things. In our case the devkit helps us to create or edit parts and world assets.

https://github.com/copybugpaste/Homebrew-Devkit/tree/master

The devkit is new but powerful already, it has both modders and devs in mind and will make both of our lives easier when it comes to creating new content that can be released in updates or uploaded to the Warehouse.

Spawner gadget

We have made the gadget load faster when you select it, and added effects that make it look better.

Default vehicles

As of now default vehicles will install for new players only. If you are not a new player you can still install them by using the "/installdefault" chat command.

Conclusion

This is a big update, we have done our best to keep track of all the changes and mention the highlights in this post. We can't guarantee everything will work perfectly at first, we may find things to tweak as it goes public. We will be on the lookout for bugs, so please report them ASAP so we can get the "hot fixes" rolling.
