Vehicles/Driver Setup Alternative

Alternative Vehicle Driver Setup

By Agent Scully

This is an alternate method of how to modify the player bones so that they do not need replication for online play, just two functions. One called:

simulated function AttachDriver(Pawn P)

And a second one called:

simulated function DetachDriver(Pawn P)

These two simulated functions will obviously, do as it says. Attach the driver to the vehicle and set the bones in place when the player gets on the bike, and detach the driver and set the bones to normal rotation. Let's take a look at how they work:

First of all you need var rotators at the top of your code. This tells your script that you'll be using rotators in AttachDriver for each bone.

var rotator PelvisDrive;
var rotator NeckDrive;
var rotator SpineDrive,SpineDrive1,SpineDrive2;
var rotator ArmDriveL,ArmDriveR;
var rotator ForeArmDriveL,ForeArmDriveR;
var rotator LeftHandDriveL,RightHandDriveR;
var rotator LFingerDrive0,LFingerDrive01,LFingerDrive02;
var rotator RFingerDrive0,RFingerDrive01,RFingerDrive02;
var rotator ThighDriveL,ThighDriveR;
var rotator CalfDriveL,CalfDriveR;
var rotator FootDriveL,FootDriveR;

So then we move onto our AttachDriver and DetachDriver:

// added for driver position resetting
simulated function AttachDriver(Pawn P)
{
    super.AttachDriver(P);


    // Pelvis --------------------------------------------------
    PelvisDrive.Yaw=8192;
    P.SetBoneRotation('Bip01 Pelvis',PelvisDrive);

    // Head ----------------------------------------------------
    NeckDrive.Yaw=-10000;
    P.SetBoneRotation('Bip01 Head',NeckDrive);

    // Spine ---------------------------------------------------
    SpineDrive.Yaw=2048;
    P.SetBoneRotation('Bip01 Spine',SpineDrive);
    //Spine 1
    SpineDrive1.Yaw=2048;
    P.SetBoneRotation('Bip01 Spine1',SpineDrive1);
    //Spine 2
    SpineDrive2.Yaw=2048;
    P.SetBoneRotation('Bip01 Spine2',SpineDrive2);

    // Arms ----------------------------------------------------
    //LeftArm
    ArmDriveL.Pitch=-4696;
    ArmDriveL.Yaw=-10000;
    ArmDriveL.Roll=6000;
    P.SetBoneRotation('Bip01 L UpperArm',ArmDriveL);
    //RightArm
    ArmDriveR.Pitch=4696;
    ArmDriveR.Yaw=-11000;
    ArmDriveR.Roll=-6000;
    P.SetBoneRotation('Bip01 R UpperArm',ArmDriveR);
    //Left ForeArm
    ForeArmDriveL.Yaw=-8010;
    P.SetBoneRotation('Bip01 L ForeArm',ForeArmDriveL);
    //Right ForeArm
    ForeArmDriveR.Yaw=-6000;
    P.SetBoneRotation('Bip01 R ForeArm',ForeArmDriveR);
    //Left Hand
    LeftHandDriveL.Pitch=6000;
    LeftHandDriveL.Roll=-16384;
    P.SetBoneRotation('Bip01 L Hand',LeftHandDriveL);
    //Right Hand
    RightHandDriveR.Pitch=5000;
    RightHandDriveR.Roll=-16384;
    P.SetBoneRotation('Bip01 R Hand',RightHandDriveR);

    // Fingers -------------------------------------------------
    //LFinger0
    LFingerDrive0.Yaw=-10000;
    P.SetBoneRotation('Bip01 L Finger0',LFingerDrive0);
    //LFinger1
    LFingerDrive01.Yaw=-10000;
    P.SetBoneRotation('Bip01 L Finger01',LFingerDrive01);
    //LFinger2
    LFingerDrive02.Yaw=-10000;
    P.SetBoneRotation('Bip01 L Finger02',LFingerDrive02);
    //RFinger0
    LFingerDrive0.Yaw=-10000;
    P.SetBoneRotation('Bip01 R Finger0',RFingerDrive0);
    //RFinger1
    LFingerDrive01.Yaw=-10000;
    P.SetBoneRotation('Bip01 R Finger01',RFingerDrive01);
    //RFinger2
    LFingerDrive02.Yaw=-10000;
    P.SetBoneRotation('Bip01 R Finger02',RFingerDrive02);

    // Legs ----------------------------------------------------
    //Left Thigh
    ThighDriveL.Pitch=5600;
    ThighDriveL.Yaw=-1000;
    ThighDriveL.Roll=3200;
    P.SetBoneRotation('Bip01 L Thigh',ThighDriveL);
    //Right Thigh
    ThighDriveR.Pitch=-5600;
    ThighDriveR.Yaw=-1000;
    ThighDriveR.Roll=-3200;
    P.SetBoneRotation('Bip01 R Thigh',ThighDriveR);
    //Left Calf
    CalfDriveL.Yaw=-10000;
    CalfDriveL.Roll=-8000;
    P.SetBoneRotation('Bip01 L Calf',CalfDriveL);
    //RightCalf
    CalfDriveR.Yaw=-10000;
    CalfDriveR.Roll=8000;
    P.SetBoneRotation('Bip01 R Calf',CalfDriveR);
    //Left Foot
    FootDriveL.Pitch=-9000;
    FootDriveL.Yaw=15000;
    P.SetBoneRotation('Bip01 L Foot',FootDriveL);
    //Right Foot
    FootDriveR.Pitch=9000;
    FootDriveR.Yaw=15000;
    P.SetBoneRotation('Bip01 R Foot',FootDriveR);


}

The (PawnP) tells the engine to rotate a pawn, in this case the player. The result for this particular bone rotation is something like this:

Image Needed?

Now we have the engine reset everything once the player leaves the bike, or else he'll be all twisted up:

simulated function DetachDriver(Pawn P)
 {
    // After the player leaves the vehicle, resets its additional bone rotations or else he'll be all twisted
    // Simply resets everything
    // Pelvis --------------------------------------------------
    Driver.SetBoneRotation('Bip01 Pelvis');
    // Head ----------------------------------------------------
    Driver.SetBoneRotation('Bip01 Head');
    // Spine ---------------------------------------------------
    Driver.SetBoneRotation('Bip01 Spine');
    Driver.SetBoneRotation('Bip01 Spine1');
    Driver.SetBoneRotation('Bip01 Spine2');
    // Arms ----------------------------------------------------
    Driver.SetBoneRotation('Bip01 L UpperArm');
    Driver.SetBoneRotation('Bip01 R UpperArm');
    Driver.SetBoneRotation('Bip01 L ForeArm');
    Driver.SetBoneRotation('Bip01 R ForeArm');
    Driver.SetBoneRotation('Bip01 L Hand');
    Driver.SetBoneRotation('Bip01 R Hand');
    // Fingers -------------------------------------------------
    Driver.SetBoneRotation('Bip01 L Finger0');
    Driver.SetBoneRotation('Bip01 L Finger01');
    Driver.SetBoneRotation('Bip01 L Finger02');
    Driver.SetBoneRotation('Bip01 R Finger0');
    Driver.SetBoneRotation('Bip01 R Finger01');
    Driver.SetBoneRotation('Bip01 R Finger02');
    // Legs ------------------------------------roll--Pitch--Yaw------------
    Driver.SetBoneRotation('Bip01 L Thigh');
    Driver.SetBoneRotation('Bip01 L Thigh');
    Driver.SetBoneRotation('Bip01 L Calf');
    Driver.SetBoneRotation('Bip01 R Calf');
    Driver.SetBoneRotation('Bip01 L Foot');
    Driver.SetBoneRotation('Bip01 R Foot');

}

This sets the driver back to the way he was before you got on the hoverbike. More simple than the other code, and no online replication or tick function needed. Enjoy :)
