Overview

Set Tether Line Color changes the color used for tether lines connecting UI panels to target objects in the scene. Reset Tether Line Color restores the system default. Choose the target in Show Panel, under Tether Line Target. The color action changes the appearance of that guidance; it does not select a target or create a panel.
In the browser Trainee App, this color is used by the panel’s directional indicator pointing toward the target object. The visual presentation differs from a tether line in a 3D scene.

​
Set Tether Line Color

The color setting is shared by panel target guidance. A later Set Tether Line Color action replaces it. Use the action in On Entry before Show Panel when a step needs a particular color. This setting controls panel guidance, not the pointer ray or a line created by grabbing an object.

​
Reset Tether Line Color

Reset restores the system default color. There is no color or target to select. The common Wait Until Complete checkbox applies only to executing the reset. For a color used in one step, add Reset Tether Line Color to that step’s On Exit actions. For a color shared across several steps, reset it when that phase ends. Resetting the color does not hide the panel or clear its target.

​
Example: Guide the Trainee to a Valve

The scene contains inlet_valve. Create an Identify Valve step and an Inspect Valve step.
1

Set the guidance color

In Identify Valve, add Set Tether Line Color to On Entry. Set Tether Line Color to #FFD700.
2

Display a panel with a target

After the color action, add Show Panel:
  • Title: “Locate the inlet valve”
  • Body: “Follow the indicator and select the inlet valve.”
  • Tether Line Target → Target Object: inlet_valve
  • Next: hidden
  • Wait Until Complete: unchecked
Configure Panel Position for the target device. The target must be available in the scene when the panel is displayed.
3

Handle the valve selection

Create a Tap transition targeting inlet_valve. Set its destination to Inspect Valve.
4

Clean up on exit

In Identify Valve → On Exit, add Hide Panel followed by Reset Tether Line Color. The custom color remains in use during the identification step and returns to the default when the trainee leaves it.

​
Using Different Colors Across Steps

Each step sets the color before displaying its targeted panel. Keep the reset at the end of the phase so it does not immediately overwrite the color intended for the current step.

​
Best Practices

  • Select a Tether Line Target in the panel; changing the color alone does not display guidance.
  • Use colors that are visible against the scene background and explain any meaning assigned to them.
  • Verify the line or directional indicator in the Trainee App on the target device.
