| I can script in LUA but have problems with the internal specific game commands/functions/variables cant see the difference between game commands and user created commands/variables/functions in existed scripts so i cant get all the pices out that i need, i was looking in the towingchain.lua for my pices but cant find the right ones and i have read many documentations on this website but cant find my way out, its more like a needle in a haystack to find your way in the docs an tutorials thats why i wanna ask someone to help me out with the last pices marked below with ??? Project data: im making a SPMT (Self Propelled Modular Transporter) each SPMT is marked/registered as a vehicle and i can drive them in game one by one but not together as one all the ingame xml things working great and i can connect so many SPMT's as i would together but only 1 vehicle where i sit in give engine power right now i show you a snipset from my XML about the attach between the SPMT's thats relevant for the scripting part <!-- XML settings (all the SEC connecting to the PRIM is working by attachableRegister.lua and attachableTowBar.lua) ---> <attacherJoints> <attacherJoint node="LengthAttacherPrim" jointType="trailer" lowerRotLimit="10 50 50" lowerTransLimit="0 0 0" upperRotRotationOffset="0" allowsJointLimitMovement="false"> <schema position="1 0" rotation="0" invertX="true" /> </attacherJoint> <attacherJoint node="LengthAttacherSec" jointType="hookLift" lowerRotLimit="0 0 0" upperRotationOffset="0" allowsJointLimitMovement="false" canTurnOnImplement="false"> <schema position="1 0" rotation="0" invertX="false"/> <objectChange node="ConnectPin" translationActive="-0.25 0 0" translationInactive="0 0 0"/> <objectChange node="BoltsFront" visibilityActive="true" visibilityInactive="false" /> </attacherJoint> <attacherJoint node="SideAttacherLeftPrim" jointType="trailer" lowerRotLimit="10 50 50" lowerTransLimit="0 0 0" upperRotRotationOffset="0" allowsJointLimitMovement="false"> <schema position="1 0" rotation="0" invertX="true" /> <objectChange node="SideAttacherLeftSec" translationActive="0 -2 0" translationInactive="0 0 0"/> </attacherJoint> <attacherJoint node="SideAttacherLeftSec" jointType="hookLift" lowerRotLimit="0 0 0" upperRotationOffset="0" allowsJointLimitMovement="false" canTurnOnImplement="false"> <schema position="1 0" rotation="0" invertX="false"/> <objectChange node="SideSupportLeft" visibilityActive="true" visibilityInactive="false" /> </attacherJoint> <attacherJoint node="SideAttacherRightPrim" jointType="trailer" lowerRotLimit="10 50 50" lowerTransLimit="0 0 0" upperRotRotationOffset="0" allowsJointLimitMovement="false"> <schema position="1 0" rotation="0" invertX="true" /> <objectChange node="SideAttacherRightSec" translationActive="0 -2 0" translationInactive="0 0 0"/> </attacherJoint> <attacherJoint node="SideAttacherRightSec" jointType="hookLift" lowerRotLimit="0 0 0" upperRotationOffset="0" allowsJointLimitMovement="false" canTurnOnImplement="false"> <schema position="1 0" rotation="0" invertX="false"/> <objectChange node="SideSupportRight" visibilityActive="true" visibilityInactive="false" /> </attacherJoint> <sounds> <attach template="ATTACH_01" /> <hydraulic template="DEFAULT_HYDRAULIC_SOUND" /> </sounds> </attacherJoints> <!-- end of my pice of XML ---> i need a script that does the following thing: When you are sitting in the scripted MAIN OBJECT behind the SPMT(in the big box) marked as vehicle he need to tell all unscripted attached SPMT childs [by xml attacherJoints] to do the same things as he self engine start/engine stop drive forward/drive backward steer left/steer right this is what i got on the LUA scripting part until now: function SeriePowered:onUpdate(dt, isActiveForInput, isActiveForInputIgnoreSelection, isSelected) if self.spec_enterable.isEntered then local FORWARD_BACKWARD, LEFT_RIGHT = 0 if self.spec_drivable.axisForward ~= nil and self.spec_drivable.axisForward ~= 0 then FORWARD_BACKWARD = self.spec_drivable.axisForward end if self.spec_drivable.axisSide ~= nil and self.spec_drivable.axisSide ~= 0 then LEFT_RIGHT = self.spec_drivable.axisSide end for ATTACHED_OBJECT_ID in pairs(???) do --(loop through attached childs) if self.spec_motorized.isMotorStarted and not ATTACHED_OBJECT_ID.spec_motorized.isMotorStarted then ATTACHED_OBJECT_ID:startMotor(false) elseif not self.spec_motorized.isMotorStarted and ATTACHED_OBJECT_ID.spec_motorized.isMotorStarted then ATTACHED_OBJECT_ID:stopMotor(false) end if FORWARD_BACKWARD ~= 0 or LEFT_RIGHT ~= 0 then Drivable.updateVehiclePhysics(ATTACHED_OBJECT_ID, FORWARD_BACKWARD, LEFT_RIGHT, BRAKE, dt) end end end end |

| Hi, I want to ask you about a Lua script for attached parts into a trailer, so has an attached booster, so I want to steer the axel on. The main trailer has steerable axel, and is possible to lift, (flip) when not use, but it will not steer as the main trailer. |
