Selection

Servicio

The Selection service controls the Instances that are selected in Roblox Studio.

This service is particularly useful when developing Plugins, as it allows the developer to access and manipulate the current selection.

Currently selected Instances can be obtained and set using the Selection:Get() and Selection:Set() functions. The Selection.SelectionChanged event fires whenever the current selection changes.

For more information on using Selection and Plugins, see Plugin.

Selection is also often used in the command bar, to set hidden properties or run functions for selected Instances.

Note this class only applies to Roblox Studio and has no applicability to games.

Sets the currently selected objects in Roblox Studio to Instances in the given array.

Calling this function will cause the Selection.SelectionChanged event to fire, unless the new selection set is identical to the previous selection.

Note this function overwrites the existing selection. However, using Selection:Get() an Instance can be added to the existing selection like so:


local selected = Selection:Get()
table.insert(selected, object)
Selection:Set(selected)

Parámetros

selection: Objects

An array of Instances to set the current selection to.

for _, object in pairs(workspace:GetDescendants()) do

table.insert(newSelection, object)
end
end
Selection:Set(newSelection)

Eventos

SelectionChanged

Fires when the Instances selected in Roblox Studio changes.

Note this event does not give the new selection. Developers will need to use the Selection:Get() function to obtain the current selection.

Although this event can be used outside of plugins and the command bar, it only applies to the selection in Roblox Studio and therefore has no functionality outside of Studio.

To change the selection use the Selection:Set() function.
