The Railway Update – Drivable Trains and More

Driveable Trains

The Railway Update Release

Trains have been promised for a while and the wait is finally over. A fully working metro system is in place, and mappers can easily create their own using new World Builder objects. The rideable metro spans the entire Default map, but it should be straightforward for mappers to copy and paste the self-contained system into their own map. Trains are spawned randomly and can be either AI or human controlled – including switching tracks. There are some extra added features to complement this new transport class so let’s cover those next.

Trains and Public Transit

Random Passengers

A transit system wouldn’t be very useful without passengers. So AI passengers are randomly spawned in trains, cars, or any vehicle for that matter. The implementation is available in the LifeSource Plugin so admins and modders can adjust spawn rates or any other parameters to best fit their server. Careful now, law enforcement travels with backup this way and I want to improve their squad behavior next along with gangs.

Interior NPC Spawns

Interior Spawns

NPC spawning was limited to the overworld only ever since BP was released years ago. That changes today with some extra options in the World Builder. Now mappers can set the possibility to spawn NPCs on a per-waypoint basis. There’s also an extra option to add a timed Delay parameter on waypoints so AI will pause for a defined amount of time. This is how train stops are implemented but can be configured to construct more elaborate scripted AI patrol routes.

Tow Truck Updates

Improved Tow Trucks

Broke Protocol is opening up slowly to community development. TheUnishark is a longtime modder for excellent plugins and assets and is now officially adding content to the base game as a developer. You can see some improvements to Tow trucks with dynamic line rendering for tow lines and some new emergency lights. Best part is that all this is easy to mod with your own vehicles so check out the latest BPResources to see how it’s done.

UI Elements Modding

Modding UI Elements

As a longtime plugin author, TheUnishark took the effort to expand and improve UI modding support. UIElements is a really powerful and customizable UI framework similar to HTML/CSS and it’s awesome to see more features unlocked in the modding API. We now have support for Sliders, Dropdowns, Radio Buttons, Toggles, and more with the new UI modding interface. There’s also a way to Set the Text field on Text Elements dynamically now and more fixes regarding packets and UI blocking interaction.

Physics and Other Improvements

Vehicle Physics

There’s been a huge physics overhaul with a more realistic torque curve for all vehicles. Engine and skid sounds are tweaked to be less ear-piercing and multiple exits are now supported. Older mods might need minimal tweaks. PLASMA_Chicken, admin and developer of the PointLife server, has been instrumental in this release in discovering and patching important errors and exploits. The community work on this update is extremely helpful and I hope to leverage that more in future updates.
