Accessing gizmo mixin

Before we start, you may question yourself: what is a “gizmo”? In simple words a gizmo is a tool used for transform which looks like:

​

Telling the workshop to select another selected object

To tell the workshop to select another keyword we can make use of PluginServices and request it.

PluginServices:SetSelected(Map.Cube) -- this will return nil if the object is not found.

To change gizmo modes for example to set it to rotation or scale or move we can use the SetGizmoMode(int mode):

-- Currently enums are not used for this
PluginServices:SetGizmoMode(1) -- now the gizmo mode is "Move"

-- Currently enums are not used for this
PluginServices:SetGizmoMode(2) -- now the gizmo mode is "Scale"

Just like that you can use GetGizmoMode to get the current gizmo mode selected by the user.

​

How shall I know if a object is selected?

You can get if already the user has selected an object with GetSelected which will return nil if no object was selected:

local object_selected = PluginServices:GetSelected()

if object_selected == nil then 
    PluginServices:SetSelected(Map.Cube)
end
