勇哥注：
需求：弄一个输入信号，它在true或者false切换时，产生随机摆放的物料。
同时演示一下输出调试信息的办法。
代码比较简单，没什么好解释的。
C#代码：
using NXOpen;
using NXOpen.CAE;
using System;
public class UserBehavior : BehaviorDef
{
RigidBody m_RigidBody = null;
SourceBehavior m_Source = null;
MCDSignal m_Signal = null;
ListingWindow listingWindow;
Random r = new Random();
// 定义刚体的位置与方向变量
NXOpen.VectorArithmetic.Vector3 oldPosition;
NXOpen.VectorArithmetic.Matrix3 oldOrientation;
NXOpen.VectorArithmetic.Vector3 newPosition;
NXOpen.VectorArithmetic.Matrix3 newOrientation;
NXOpen.Session theSession;
NXOpen.Part workPart;
bool bFlag = false;
bool lastSignalValue = false; // 用于存储上一次的信号值
public override void Define(IDefinitionContext access)
{
access.Connect("Rigid Body", out m_RigidBody);
access.Connect("Object Source", out m_Source);
access.Connect("Trigger1", out m_Signal);
m_Source.Active = false;
}
public override void Start(IRuntimeContext context)
{
oldPosition = m_RigidBody.Position;
oldOrientation = m_RigidBody.Orientation;
theSession = NXOpen.Session.GetSession();
workPart = theSession.Parts.Work;
// open listingWindow
listingWindow = theSession.ListingWindow;
if (!listingWindow.IsOpen)
listingWindow.Open();
}
public override void Stop(IRuntimeContext context)
{
// Insert stopping code here
}
public override void Step(IRuntimeContext context, double dt)
{
// NXOPEN api不能在Step函数中调用，因为Step在工作线程中运行。
//只有MCD运行时api可以在Step函数中调用
//在这里插入仿真步骤代码
if (m_Signal != null)
{
if (m_Signal.BoolValue != lastSignalValue)
{
// 先输出调试信息，再更新lastSignalValue
listingWindow.WriteLine($"Signal changed to1: {m_Signal.BoolValue}, Last signal was: {lastSignalValue}");
lastSignalValue = m_Signal.BoolValue; // 更新上一次的信号值
m_Source.Active = true;
//listingWindow.WriteLine($"{DateTime.Now.ToString()}.....");
listingWindow.WriteLine($"m_Source.Active is set to: {m_Source.Active}");
listingWindow.WriteLine("Inside if (m_Source.Active) block");
listingWindow.WriteLine($"{DateTime.Now.ToString()}.....");
// 重新初始化Random对象以确保更好的随机性
r = new Random();
// 设置随机位置x
newPosition = oldPosition;
newPosition.x += (double)r.Next(-150, 150) / 1000;
// 重置方向
newOrientation = oldOrientation;
// Z轴以任意角度旋转
newOrientation.Rotate(0.0, 0.0, 1.0, Math.PI * 180 / (double)r.Next(1, 30));
// 设置刚体的新位置
m_RigidBody.Position = newPosition;
// 为刚体设置新的方向
m_RigidBody.Orientation = newOrientation;
}
}
}
public override void Refresh(IRuntimeContext context)
{
// Insert simulation refreshing code here. This is called when it is safe // to read and change runtime variables outside of the main control loop. } public override void Repaint()
{
// Insert simulation repainting code here. This is where you use the data
// taken from the runtime to update the display.
}
}
public override void Repaint()
{
// Insert simulation repainting code here. This is where you use the data
// taken from the runtime to update the display.
}
}
