I am going to do my first mod. The mesh ist 70% finished and now I start thinking about bringing ingame. But I wonder which node and beam structure would be more convenient for a first mod. So please feel free to write your opinion.
This is completely false and grammatically terrible, RoR lacks features like node names as well as a lack of proper debugging and testing tools. BeamNG is not exactly easier, but is a lot less headache inducing.
As someone who actually mods and does his Jbeam through Notepad++ I can tell you that having been wanting to mod since RoR days Jbeam is a thousand times easier to look at than whatever that stuff was back in RoR .
Rigs of Rods Code: nodes2 myNode,0,0,0 myNode2,1,1,0 myNode3,0,1,0 beams myNode,myNode2 ;etc BeamNG Code: "nodes":[ ["id", "posX", "posY", "posZ"], ["myNode",0,0,0], ["myNode2",1,0,1], ["myNode3",0,0,1], ], "beams" :[ ["id1:", "id2:"], ["myNode","myNode2"], //etc ], The jbeam/truck files have their similarities. BUT BeamNG has better simulation speeds, constantly improving physics features, has DAE support (so you don't have to convert every vehicle part to a .mesh), etc. As a previous Rigs of Rods modder I suggest you at least start with BeamNG.
Don't forget that Jbeam, can be separated into separate files, and not one big Cluster Fuck, so you can develop in whatever way makes things easiest for you.
