Make an EZ-Builder Behavior Control

Custom Movement Panel

The EZ-Builder software uses controls that register themselves as a movement panel. This allows your plugin to listen to movement requests from other controls. When any control or EZ-Script calls for a movement direction (i.e. Forward, Left, Stop, etc), your plugin can be responsible for moving the robot. There can only be one Movement Panel per robot project. This is because there is only one method of locomotion for a robot, which this Movement Panel would be responsible for.

To understand more about how Movement Panels work in EZ-Builder, read this tutorial.

What's In A Movement Panel?
A Movement Panel will have buttons that lets the user specify directions that the robot should move. Your Movement Panel will be responsible for the robot moving. This means that anywhere a direction is specified, your control will be responsible for moving the robot. Generally a Movement Panel has speed controls in the form of trackbars of some sort. 

Code Example
Want to make your own movement panel? Here is an example of how to implement code which will respond to movement requests:


public FormMain()
: base() {


// Assign this control as a Movement Panel so the software knows who owns the movements
  EZ_Builder.FormMain.MovementPanel = this;

// Assign the movement locomotion style for this control.
// There are different kind of locomotion for your robot, and this helps other
// controls know what to expect when a movement is happening.
// Check out the ENUM to see what other locomotion styles there are that
// fits your Movement Panel type.
  EZBManager.MovementManager.LocomotionStyle = LocomotionStyleEnum.GAIT;

// assign the movement event
// this event is raised when another EZ-Builder control requests movement
  EZBManager.MovementManager.OnMovement2 += Movement_OnMovement2;

// assign the speed change event
// this event is raised when another control or user changes the speed
EZBManager.MovementManager.OnSpeedChanged += Movement_OnSpeedChanged;

private void FormModifiedServoMovementPanel_FormClosing(object sender, FormClosingEventArgs e) {

// Remove this control as a Movement Panel
  EZ_Builder.FormMain.MovementPanel = null;

EZBManager.MovementManager.OnSpeedChanged -= Movement_OnSpeedChanged;

EZBManager.MovementManager.OnMovement2 -= Movement_OnMovement2;

private void Movement_OnSpeedChanged(int speedLeft, int speedRight) {

// do something with the speed change

private void Movement_OnMovement2(MovementManager.MovementDirectionEnum direction, byte speedLeft, byte speedRight) {

// **
// do something based on the speed
// handle speed change here
// **

// Now do something based on the new movement direction

if (direction == MovementManager.MovementDirectionEnum.Forward) {

// handle custom Forward movement

} else if (direction == MovementManager.MovementDirectionEnum.Reverse) {

// handle custom Reverse movement

} else if (direction == MovementManager.MovementDirectionEnum.Right) {

// handle custom Right movement

} else if (direction == MovementManager.MovementDirectionEnum.Left) {

// handle custom Left movement

} else if (direction == MovementManager.MovementDirectionEnum.Stop) {

// handle custom Stop movement

Joinny, you have to add the referencing by following the instructions in this tutorial. They are outlined with step by step to easily follow. Click add references, and browse to the appropriate files as directed in the tutorial. I can’t write anything clearer in response. The step to add references is incredibly clear but you’re skipping it.
The error cannot read the COM file, I downloaded it and when I follow the instructions, I get an error, while other files read normally.

sorry for me but i tried many different ways but still show the error,I couldn't find EZ_B.dll file even though I downloaded it
None of the required references are in your list. Please follow the tutorial. It explains exactly how to click the browse button and navigate to the folder and select the files.
Sorry, but the reason I can't reference is because there is no file in the EZ_B folder and there is an error : this folder is empty , I am trying to solve it. I would like to thank DJ sure for answering my superfluous questions and I'm sorry for bothering you
