Selection

パラメータ

戻り値

Returns an array of currently selected Instances in Roblox Studio.

If no Instances are selected, the array returned be empty. This function can be used in conjunction with the Selection.SelectionChanged event to get the selection whenever it changes.

Note, this function can only be used in Plugins or the command line.

For changing the current selection, please see Selection:Set().

戻り値

local Selection = game:GetService("Selection")

for _, object in pairs(Selection:Get()) do
	if object:IsA("BasePart") then
		object.CFrame = object.CFrame * CFrame.Angles(0, math.pi / 2, 0)
	end
end

local selection = game:GetService("Selection")

selection.SelectionChanged:Connect(function()
	print("Selection contains " .. #selection:Get() .. " items.")
end)

パラメータ

戻り値

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)

戻り値

local Selection = game:GetService("Selection")

local newSelection = {}
for _, object in pairs(workspace:GetDescendants()) do
	if object:IsA("BasePart") and object.BrickColor == BrickColor.new("Bright red") then
		table.insert(newSelection, object)
	end
end

Selection:Set(newSelection)

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.

local selection = game:GetService("Selection")

selection.SelectionChanged:Connect(function()
	print("Selection contains " .. #selection:Get() .. " items.")
end)
