PrismaticConstraint Class

Extends Constraint
Defined in: src/constraints/PrismaticConstraint.js:9

滑块约束， 只允许刚体只能沿着彼此之间的一条直线运动。参见 这一教程

构造器

PrismaticConstraint

(
  • bodyA
  • bodyB
  • [options]
)

Defined in src/constraints/PrismaticConstraint.js:9

参数:

  • bodyA Body
  • bodyB Body
  • [options] Object 可选
    • [maxForce] Number 可选

      施加在这一约束上的最大作用力

    • [localAnchorA] Array 可选

      BodyA 的目标点，在其范围内中定义

    • [localAnchorB] Array 可选

      BodyB 的目标点，在其范围内中定义

    • [localAxisA] Array 可选

      BodyB 中的点可能沿着滑动的一条轴， 在BodyA 范围内定义

    • [disableRotationalLock] Boolean 可选

      如果为真，BodyB 将自由地绕着这个目标点旋转
