Just Cause 2 Multiplayer: Welcome to Build World
On the Just Cause 2 Multiplayer server Jman100's Freeroam Construction Sandbox, players can build cities, obstacle courses, and incredibly creepy statues. Jman100 scripted a custom server that includes an expansive build menu listing hundreds of objects from Just Cause 2. Players are building weird and hilarious things. Jman showed us around his server and told us how he built it.
Build World was scripted in two weeks
Jman100: "[Build World took] about 2 weeks of coding, with almost all of my free time going towards it. The individual objects are all objects/models that are found in the base game of Just Cause 2...I used a model viewer script that was released alongside [JC2-MP mod version] 0.1.2, created by JCMP beta tester and script creator Patawic (creator of the popular Derby script). I modified it a bit to make it easier to use for my needs. I then basically sat there and manually went through tons of objects (I still haven't been through them all) and found the best ones to use in Build World...Every single model that can be found in the game can be spawned in, from fish in the water and birds in the sky to giant skyscrapers and even the hot air balloon."
DirtyD's city
Jman100: "DirtyD's city is my favorite so far. He's a great builder in the server and just recently became a mod. He's spent close to 60 hours on just the city he made and about 175 hours total time working on build stuff. He is currently working on another floating rock island that looks amazing so far. There are also small builds people have made all over Panau. It's pretty fun to just fly around finding random builds people have left."
Build World's object spawning menu
Jman100: "My first version of [the fine tuning and positioning tools] used a separate tab in the spawn menu. It was very roughly coded and worked poorly, so I re-did that (shout-out to Philpax and SonicXVe for helping) to where a small menu popped up when you hold R. It allows you to set the position and angle however you want on the last object spawned."
Static mannequins
Jman100: "As of right now JCMP can only spawn static objects. This means they do not have any animation or dynamic movement of any kind, such as exploding barrels or destructible trees. Animations that are not dynamic however, such as trees swaying in the wind, do apply to the static models. It's safe to say that in the future JCMP will be able to spawn dynamic objects, it's definitely possible. And yes, Build World will be updated to accommodate them!"
Island in the sky
Jman100: "I had the idea for [Build World] as soon as the update to JCMP was released, version 0.1.2, that allowed for object spawning. I thought about just having an addition to the buy menu, an in game menu for spawning vehicles and weapons, that would allow for objects to be spawned wherever players wanted. However, I still wanted my freeroam players to be able to have their fun without running into giant floating sheets of ice every few feet. So I decided to put Build World in its own world instance."
Keeping Build World Clean
Jman100: "I have to manually do upkeep on Build World. Most of the time it's because a user has spawned a giant stack of bridges to the sky or something similar. The biggest reason, for now, is due to a limit on the maximum number of objects that the server can hold. Until the next update to JCMP, there is a maximum of 65535 objects. So I have to keep useless and spammed objects cleared out as much as possible. After the next update, that limit will be raised quite a bit into the millions (or maybe even the billions). I may also implement hotspots around the teleport locations like airport and racetrack so that objects cannot be spawned there, as well as some sort of area protection to prevent people from ruining other peoples build work."
Improving build world
Jman100: "My current plans for Build World include private world instances for users to build uninterrupted by other players, and the ability to make their worlds open for other users to visit, or locked and invite only. I also plan to change the way Build World stores it's objects and auto saving. Right now objects have to be manually stored to an external file and loaded separately when the script is reloaded/updated for any reason."
A network of skyroads
Jman100: "One thing that I was surprised [by] is how as a collective the community has made a sort of roadway system all over Panau. DirtyD himself made a road that goes from the bottom right of the map all the way to the top, and others have hooked onto that roadway and built their own. The main road model that is used makes up a few thousand of the total objects spawned in Build World."
