Class MotoVehicleConstraint

An anti rollbar is a stiff spring that connects two wheels to reduce the amount of roll the vehicle makes in sharp corners See: Anti-roll Bar

Fraction of half the wheel width (or wheel radius if it is smaller) that is used as the convex radius.

Max angle that is considered for colliding wheels. This is to avoid colliding with vertical walls.

Object layer to test collision with.

Sets the radius of the sphere used in cast. Note, that castType needs to be set to VEHICLE_CAST_TYPE_SPHERE for this to be used.

Collision tester that tests wheels collision. Following types available:

VEHICLE_CAST_TYPE_RAY
Copy

VEHICLE_CAST_TYPE_SPHERE
Copy

VEHICLE_CAST_TYPE_CYLINDER
Copy

World space up vector, used to avoid colliding with vertical walls.

How long it takes to release the clutch (go to full friction), only used when mode is set to TRANSMISSION_AUTO.

Strength of the clutch when fully engaged. Total torque a clutch applies is

Torque = ClutchStrength * (Velocity Engine - Avg Velocity Wheels At Clutch)
Copy

Ratio max / min average wheel speed of each differential (measured at the clutch). When the ratio is exceeded all torque gets distributed to the differential with the minimal average velocity. This allows implementing a limited slip differential between differentials. Set to Number.MAX_VALUE for an open differential. Value should be greater than 1.

List of differentials and their properties.

The PlayCanvas Entity that is used as a visual model for the vehicle body. Its position and rotation will automatically be updated to match the physical body.

Vector indicating forward direction of the vehicle (in local space to the body).

Ratio in rotation rate between engine and gear box, first element is 1st gear, 2nd element 2nd gear etc.

Moment of inertia of the engine.

Defines the maximum pitch/roll angle, can be used to avoid the car from getting upside down. The vehicle up direction will stay within a cone centered around the up axis with half top angle maxPitchRollAngle, set to pi to turn off.

Max amount of revolutions per minute the engine can generate.

Max amount of torque that the engine can deliver.

Min amount of revolutions per minute the engine can produce without stalling.

How to switch gears. Following modes available:

TRANSMISSION_AUTO
Copy

TRANSMISSION_MANUAL
Copy

Curve that describes a ratio of the max torque the engine can produce vs the fraction of the max RPM of the engine.

Override for the number of solver position iterations to run. If set to 0, the constraint will use global default set by Physics initialization setting JoltInitSettings.numPositionSteps.

Override for the number of solver velocity iterations to run. If set to 0, the constraint will use global default set by Physics initialization setting JoltInitSettings.numVelocitySteps.

Ratio in rotation rate between engine and gear box when driving in reverse.

If RPM of engine is smaller then this we will shift a gear down, only used when mode is set to TRANSMISSION_AUTO.

If RPM of engine is bigger then this we will shift a gear up, only used when mode is set to TRANSMISSION_AUTO.

How long to wait after releasing the clutch before another switch is attempted (s), only used when mode is set to TRANSMISSION_AUTO.

How long it takes to switch gears, only used only used when mode is set to TRANSMISSION_AUTO.

Vector indicating the up direction of the vehicle (in local space to the body).

Angular damping factor of the wheel:

dw/dt = -c * w
Copy

An array of objects that describe each wheel.
