Thing Properties Window
This dialog allows you to edit all the thing properties. When a selection of multiple things is made, some fields may appear grayed or empty in case they are different for some of the selected elements. Setting a value in grayed or empty field will apply this to the entire selection.
Properties
On the left of this tab you can select the Thing Type. Either select it from the list or enter the type number in the field below the list. If it is a thing type that is in the Game Configuration, the information known about that thing type is displayed as well.On the right you can change the Settings for the thing. The settings available depend on the Game Configuration you are using. Below that you can change the Angle. In Hexen and UDMF formats, you can also specify the Z height of the thing. The Z height is usually relative to the sector floor, but for some things the Z height is absolute (refer to the sourceport documentation).
