GearConstraint Class

Extends Constraint
Defined in: src/constraints/GearConstraint.js:8

限制两个物体的角度相等。如果一个变速比不为1，则BodyA 的角度必须为BodyB 的倍数角度。

构造器

GearConstraint

(
  • bodyA
  • bodyB
  • [options]
)

Defined in src/constraints/GearConstraint.js:8

参数:

  • bodyA Body
  • bodyB Body
  • [options] Object 可选
    • [angle=0] Number 可选

      刚体间的相对角度，将被设置成刚体间当前的角度（变速比也会被算进去）

    • [ratio=1] Number 可选

      变速比

    • [maxTorque] Number 可选

      施加的最大扭矩

Example:

var constraint = new GearConstraint(bodyA, bodyB);
        world.addConstraint(constraint);
        
var constraint = new GearConstraint(bodyA, bodyB, {
            ratio: 2,
            maxTorque: 1000
        });
        world.addConstraint(constraint);
