hi everyone, i'm in the process of creating a mod. i don't want to divulge too much yet because i like keeping it somewhat under wraps until i've got a somewhat working prototype. for the mod i need a rotator that spins at a constant speed. it cannot be a prop since it needs to have collision. "drive_sprocket":{ "information":{ "authors":"Blender JBeam Exporter v0.3.5", "name":"drive sprocket", }, "slotType":"drive_sprocket", "powertrain" : [ ["type", "name", "inputName", "inputIndex"], ["electricMotor", "motor", "", 0 ], ["frictionClutch", "blutch", "motor", 1, ], ["shaft", "shaft", "blutch", 1, {"gearRatio": 1.01, "connectedWheel":"radial_sprocket"}], ], "motor": { "torque":, [ ["rpm", "torque"], [0, 15000], [2000, 15000], [2100, 0], ], "electricsThrottleName": "throttle", "electricsThrottleFactorName": "throttleFactor", "idleRPM":600, "maxRPM":2000, "inertia":1, "friction":5, "dynamicFriction": 0, "torqueReactionNodes:":["en2l","en2r","enf"], "soundConfig":"soundConfig", }, "soundConfig": { "sampleName": "ElectricSpinner_01", "mainGain": -4, }, "rotators":, [ ["name","[group]:","node1:","node2:","nodeArm:","wheelDir"], {"radius":0.5}, {"brakeTorque":0, "brakeSpring":0}, {"parkingTorque":0}, {"speedo" : false}, ["radial_sprocket", ["radial_sprocket"], "enf", "enff", "en2l", -1], ], i currently have it set up like this. i found that i'm not able to use drive from the main engine since that would require there to be two clutches on the engine. setting an idle rpm on an electric motor so far doesn't work. and adding another combustion engine (which i could regulate to a certain rpm) crashes the mod.
