Entspy

Entspy was developed to be a program for viewing and editing the entities of compiled map (.bsp) files.

Once a bsp file is loaded, the window show two halves. On the left is a tree-type list of all entities in the map, starting with the Worldspawn entity. Entities which are parented are shown as children of the parent entity.

Selecting an entity in the list shows the properties of that entity on the right side of the window. The four principal entity properties (classname, targetname, parentname & origin) are shown at the top, with the complete list in the table below.

A property and its value can be edited by clicking on the table entry or in the top four properties. (Note that no changes to the map are written to disk until the Save BSP menu command is performed.)
