Properties[edit]

KarmaConstraint[edit]

float KDesiredAngle 
65535 = 360 degrees
float KAltDesiredAngle 
65535 = 360 degrees
float KDesiredAngVel 
65535 = 1 rotation per second
EHingeType KHingeType 
float KMaxTorque 
float KProportionalGap 
65535 = 360 degrees
float KStiffness 
float KDamping 

Hidden[edit]

bool KUseAltDesired 
Will use KAltDesiredAngle.
float KCurrentAngle 

Enums[edit]

EHingeType[edit]

HT_Normal 
Will spin freely around the given axis, KDesiredAngle.
HT_Springy 
The given spin axis is able to move, but will return to normal.
HT_Motor 
Will constantly spin around the given axis.
HT_Controlled 
Somewhere between HT_Springy and HT_Motor, where a constant spin is applied to an axis that is able to move.

States[edit]

Default (auto)[edit]

In this state nothing will happen if this hinge is triggered or untriggered.

Ignores Trigger, UnTrigger.

ToggleMotor[edit]

In this state, Trigger will cause the hinge type to change to HT_Motor. Another trigger will toggle it to HT_Controlled, and it will try and maintain its current angle.

Ignores UnTrigger.

Functions[edit]

Trigger( Actor Other, Pawn EventInstigator ) 
If KHingeType == HT_Motor, sets KDesiredAngle = KCurrentAngle, KUseAltDesired = False and KHingeType = HT_Controlled. Otherwise sets KHingeType = HT_Motor. Calls KUpdateConstraintParams() and KConstraintActor1.KWake().
Begin 
Sets KHingeType = HT_Controlled and KUseAltDesired = False. Calls KUpdateConstraintParams().

ControlMotor[edit]

In this state, Trigger will turn motor on. Untrigger will turn toggle it to HT_Controlled, and it will try and maintain its current angle.

Functions[edit]

Trigger( Actor Other, Pawn EventInstigator ) 
if KHingeType != HT_Motor, sets KHingeType = HT_Motor and calls KUpdateConstraintParams() and KConstraintActor1.KWake().
UnTrigger( Actor Other, Pawn EventInstigator ) 
if KHingeType == HT_Motor, sets KDesiredAngle = KCurrentAngle, KUseAltDesired = False and KHingeType = HT_Controlled, then calls KUpdateConstraintParams() and KConstraintActor1.KWake().
Begin 
Sets KHingeType = HT_Controlled and KUseAltDesired = False. Calls KUpdateConstraintParams().

ToggleDesired[edit]

In this state a trigger will toggle the hinge between using KDesiredAngle and KAltDesiredAngle. It will use whatever the current KHingeType is to achieve this, so this is only useful with HT_Controlled and HT_Springy.

Ignores Untrigger.

Functions[edit]

Trigger( Actor Other, Pawn EventInstigator ) 
Toggles KUseAltDesired. Calls KUpdateConstraintParams() and KConstraintActor1.KWake().

ControlDesired[edit]

In this state, trigger will cause the hinge to use KAltDesiredAngle, untrigger will caus it to use KAltDesiredAngle.

Functions[edit]

Trigger( Actor Other, Pawn EventInstigator ) 
Sets KUseAltDesired = True and calls KUpdateConstraintParams() and KConstraintActor1.KWake().
UnTrigger( Actor Other, Pawn EventInstigator ) 
Sets KUseAltDesired = False and calls KUpdateConstraintParams() and KConstraintActor1.KWake().
