Function LuaGet

engine/gui/src/gui_script.cpp:693–786

gets the named property of a specified gui node * * Instead of using specific getters such as gui.get_position or gui.get_scale, * you can use gui.get instead and supply the property as a string or a hash. * While this function is similar to go.get, there are a few more restrictions * when operating in the gui namespace. Most notably, only these explicitly named properties
