Components are generic key-value stores that extend/overwrite Jbeam code. They use the Json dictionary syntax. They are an experimental feature in BeamNG update 0.32.
"components": {
"wheels": {
"FL": {
"diameter": 0.56,
"something": 3,
},
},
"cameras": {
"MyDefault":{
"distance":4,
"distanceMin":3,
"offset":{"x":0.0, "y":0.0, "z":0.59},
"fov":65,
}
}
}
Components are used in Jbeam via a $>> operator. It points to a data store that will be used for the value.
"cameraExternal":"$>>components.cameras.MyDefault",
Usage
A part can extend or overwrite component data:
/// the main part
"components": {
"wheels": {
"FL": {
"diameter": 0.56,
"something": 3,
},
},
}
/// the sub part
"components": {
"wheels": {
"RR": {
"diameter": 0.1,
"something": 1,
},
"FL": {
"diameter": 2, // overwrites
"somethingElse": 3,
},
}
}
Components work not only for table data, but also for modifiers:
"components": {
"collisionEnabled": true,
},
"nodes" :[
["id", "posX", "posY", "posZ"],
{"collision" :"$>>components.collisionEnabled"},
],
They can be used as table rows:
"components": {
["node3", -0.90, -0.93, 0.23],
},
"nodes" :[
["id", "posX", "posY", "posZ"],
["node1", -0.90, -0.93, 0.23],
["node2", -0.33, -0.95, 0.23],
"$>>components.node3",
["node4", 0.90, -0.93, 0.23],
{"group":""},
],
They can also be used inside of another component which is a table row:
"components": {
"posZ": 0.23,
["node3", -0.90, -0.93, "$>>components.posZ"],
},
"nodes" :[
["id", "posX", "posY", "posZ"],
["node1", -0.90, -0.93, 0.23],
["node2", -0.33, -0.95, 0.23],
"$>>components.node3",
["node4", 0.90, -0.93, 0.23],
{"group":""},
],
Example
A component could be used to define pressureWheel options, to keep wheels Jbeam clean:
"components": {
"wheelConfig_FR": {
"selfCollision":false,
"collision":true,
"hubcapBreakGroup":"hubcap_FR",
"hubcapGroup":"hubcap_FR",
"axleBeams":["axle_FR"],
"torqueCoupling:":"ta1",
"torqueArm:":"tc1",
"steerAxisUp:":"fh2r",
"steerAxisDown:":"fh1r",
//"hubcapBreakGroup":"hubcap_FL",
//"hubcapGroup":"hubcap_FL",
//"axleBeams":["axle_FL"],
"disableMeshBreaking":false,
"disableTriangleBreaking":false,
"enableHubcaps":false,
"enableTireLbeams":false,
"enableTireSideReinfBeams":false,
"enableTireReinfBeams":false,
"enableTreadReinfBeams":false,
"enableTirePeripheryReinfBeams":false,
"loadSensitivitySlope":"",
"noLoadCoef":"",
"fullLoadCoef":"",
"frictionCoef":"",
"slidingFrictionCoef":"",
"softnessCoef":0.5,
"treadCoef":1.0,
"TEST": 123,
}
}
"pressureWheels":[
["name","hubGroup","group","node1:","node2:","nodeS","nodeArm:","wheelDir"],
//front
["FR", "wheel_FR", "tire_FR", "fw1rr", "fw1r", 9999, "fh5r", 1, "$>>components.wheelConfig_FR"],
],
