struct in UnityEngine

Description 描述

The JointMotor is used to motorize a joint.

该关节马达用于关节的机动。

For example the HingeJoint can be told to rotate at a given speed and force. The joint will then attempt to reach the velocity with the given maximum force.

例如：铰链关节可以被指定的速度和力旋转。该关节将会尝试达到指定最大力的速度。

JavaScript:

function Start() {
	var hinge = GetComponent.<HingeJoint>();
 
	// Make the hinge motor rotate with 90 degrees per second and a strong force.
	var motor = hinge.motor;
	motor.force = 100;
	motor.targetVelocity = 90;
	motor.freeSpin = false;
	hinge.motor = motor;
}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    void Start() {
        HingeJoint hinge = GetComponent<HingeJoint>();
        JointMotor motor = hinge.motor;
        motor.force = 100;
        motor.targetVelocity = 90;
        motor.freeSpin = false;
        hinge.motor = motor;
    }
}

Variables 变量

force	The motor will apply a force. 该马达将会施加一个力。
freeSpin	If freeSpin is enabled the motor will only accelerate but never slow down. 如果启用了freeSpin，那么马达将会仅加速而不会减速。
targetVelocity	The motor will apply a force up to force to achieve targetVelocity. 该马达将会施加一个力以达到指定目标速度。
