Target Parameters
A Target Parameter does not store a simple numeric value. Instead, it stores a reference to another object or parameter within the project.
This allows systems in Grid Studio to connect and interact with each other by directly referencing other elements.
Target parameters are commonly used to link objects, parameters, or system components together.
Selecting a Target
When a parameter uses the Target control mode, the parameter field displays a Select an object button.
Clicking this button opens a selection interface that allows the user to choose the target object or parameter.
Once selected, the parameter stores a reference to that element.
Target Selection Menu
Pressing Select an object opens a selection menu.
This menu shows elements from the project that are compatible with the parameter.
The list is context-aware, meaning it filters entries based on the expected type.
For example, depending on the parameter configuration, the menu may show:
compatible objects
specific object types
parameters from other objects
The menu is organized using the Project Tree structure, making it easier to navigate larger projects.
In some cases, especially when selecting parameters, the list may contain many entries.
Interactive Target Selection
In addition to the menu, Grid Studio provides a faster method for selecting targets.
Instead of clicking and releasing the Select an object button, users can press and hold the button.
While holding the mouse button, the cursor can be moved across the interface to locate the desired element.
During this interaction it is possible to:
move through the Inspector
change the currently selected object
navigate through parameter lists
Once the desired parameter or object is highlighted, releasing the mouse button will assign it as the target.
This behavior works similarly to drag-and-drop, but the interaction is initiated from the target parameter.
This approach makes it much easier to link parameters in large projects without navigating long selection lists.
Drag and Drop Selection
Targets can also be assigned using drag and drop.
To do this, drag a compatible object or parameter and drop it onto the target parameter field.
If the dropped element is compatible, the parameter will automatically reference the dropped object or parameter.
This method provides a fast and intuitive way to create links between elements while working in the Inspector or other views.
Drag and drop is especially useful when the source parameter or object is already visible, as it avoids opening the target selection menu.
Working with Parameter Targets
When a parameter references another parameter, the value of the target parameter is used.
Any changes to the referenced parameter will automatically update the parameter that uses the target reference.
This allows parameters to be connected and synchronized across different objects.
Typical Use Cases
Target parameters are commonly used in situations where objects need to reference or interact with other elements.
Examples include:
referencing another object's parameter
linking systems together
selecting devices or system components
connecting control parameters across objects
Target parameters make it possible to create flexible relationships between objects without duplicating configuration values.
