Category: Core
Brief Description¶
A hinge between two 3D bodies.
Member Variables¶
- float angular_limit/bias - The speed with which the rotation across the axis perpendicular to the hinge gets corrected.
- bool angular_limit/enable - If
true
the hinges maximum and minimum rotation, defined by angular_limit/lower and angular_limit/upper has effects. - float angular_limit/lower - The minimum rotation. only active if angular_limit/enable is
true
. - float angular_limit/relaxation - The lower this value, the more the rotation gets slowed down.
- float angular_limit/softness
- float angular_limit/upper - The maximum rotation. only active if angular_limit/enable is
true
. - bool motor/enable - When activated, a motor turns the hinge.
- float motor/max_impulse - Maximum acceleration for the motor.
- float motor/target_velocity - Target speed for the motor.
- float params/bias - The speed with which the two bodies get pulled together when they move in different directions.
Enums¶
enum Flag
- FLAG_USE_LIMIT = 0 — If
true
the hinges maximum and minimum rotation, defined by angular_limit/lower and angular_limit/upper has effects. - FLAG_ENABLE_MOTOR = 1 — When activated, a motor turns the hinge.
- FLAG_MAX = 2 — End flag of FLAG_* constants, used internally.
enum Param
- PARAM_BIAS = 0 — The speed with which the two bodies get pulled together when they move in different directions.
- PARAM_LIMIT_UPPER = 1 — The maximum rotation. only active if angular_limit/enable is
true
. - PARAM_LIMIT_LOWER = 2 — The minimum rotation. only active if angular_limit/enable is
true
. - PARAM_LIMIT_BIAS = 3 — The speed with which the rotation across the axis perpendicular to the hinge gets corrected.
- PARAM_LIMIT_SOFTNESS = 4
- PARAM_LIMIT_RELAXATION = 5 — The lower this value, the more the rotation gets slowed down.
- PARAM_MOTOR_TARGET_VELOCITY = 6 — Target speed for the motor.
- PARAM_MOTOR_MAX_IMPULSE = 7 — Maximum acceleration for the motor.
- PARAM_MAX = 8 — End flag of PARAM_* constants, used internally.
Description¶
Normally uses the z-axis of body A as the hinge axis, another axis can be specified when adding it manually though.
