The '''Object Properties dialog''' box is the primary method of modifying [[entity]] properties. It also allows you to adjust [[VisGroup]] properties for one or many brushes. For non-entity objects, only the VisGroup tab will appear in the '''Object Properties''' dialog box. Information about individual entities can be found in the [[list of entities|list of entities]].

==Class Info Tab==

{{Warning|Adding quotation marks in any parameter will result in a compiling error like "Unexpected End of File". A source map with such comments will crash Hammer when the file is loading.<p>To fix this, edit the VMF file with a text editor such as Notepad or Notepad++.  Usually Hammer will crash immediately when the VMF is saved if an invalid parameter exists; if this happens, search the file for any information you can remember about the object that was being edited.  Try the object name, texture name, and entity names.  The quotation marks that surround the parameter should not be removed - remove only the quotations inside the parameter.  It is recommended to create a backup of the file before attempting to edit it yourself.</p>}}
 
===Class===

This drop-down list contains all the entities available on the selected object.

===Help===

Clicking this button will open the help dialog for the selected entity class. The help dialog gives a description of the entity, its [[keyvalue]]s, as well as all of its [[Inputs and Outputs]].

===Keyvalues===

This is a list of the different parameters that can be changed on the entity. Click on an category (or <i>Key</i>) on the left, and the data (<i>value</i>) for that key is displayed in the box to the right. You can change values for the entity by typing in the field.

===Angles===

The angle control is comprised of two parts - the Angle text box and the angle compass. These two allow you to accomplish the same thing - setting an angle between 0 and 359. The Angle text box also allows you to choose "up" and "down" which correspond to angles -1 and -2.

===Browse===

Some entity properties - those that require a path/filename of a [[sprite]], [[sound]], or [[model]] - will have a '''Browse''' button beside their property when you click on them. Clicking on this button will allow you to browse through the appropriate game directory for the sprite, sound, or model. This behavior is controlled by the game data file. For more information on that, see [[FGD]].

===Mark===

Some entity properties - those that point to another named entity, have a Mark button. When pressed, the selection switches from the current entity to the entity named in the value field.

===Mark + Add===

Works identical to '''Mark''', except that it <i>adds</i> the marked item to the selection instead of switching the selection to it.

===Eyedropper===

Clicking this button will turn the mouse cursor into the eyedropper icon. Clicking on any named entity in the 3D view will paste the clicked entity's name into the value field. Note that the entity clicked must have a name, or the eyedropper will have no data to paste.

===Copy===

This will copy all the keyvalues and parameters from the currently selected entity to the clipboard. This is independent of the standard '''Copy''' command.

===Paste===

This will paste the keyvalues in the clipboard onto the currently selected entities. This is independent of the standard '''Paste''' command.

===Comments===

Allows you to enter comments for the entity. This information is saved with the map. Useful for documenting the purpose of the entity in your map. For example, "This entity triggers the gate to open when the player walks into the room."

===SmartEdit===
[[Image:hammer_objectproperties2.png|frame|right|Object Properties with SmartEdit disabled.]]

Class Info has two modes, a regular editing mode and '''SmartEdit''' (toggled by the '''SmartEdit''' button). When you use the '''SmartEdit''' mode, all of the entity's <i>keyvalue</i> (entity variable) descriptions are shown to you. This button turns off the "friendly" interface to the keyvalue data and lets you edit keys and values directly, for advanced users.<br style="clear:both">

==Outputs Tab==

List all of the Outputs for the current entity, and lets you add additional '''Outputs''' that the selected entity fires. See [[Inputs and Outputs]] for more information on working with '''Outputs'''.

==Inputs Tab==

Shows all of the Inputs to the current entity. Double-click an Input to go to the Outputs tab of the entity that originated the '''Input'''. See [[Inputs and Outputs]] for more information on working with '''Outputs'''.

==Flags Tab==

You will find listed here all the available flags for an entity. This section is only available when editing an the properties of entities. A flag allows you to toggle on or off specific features of an entity. If more than one entity is selected, some of the flag checkmarks may appear gray. This signifies that the flag is enabled on only some of the selected entities. More information on flag usage for specific entities can be found in the [[List of entities|list of entities]].

==VisGroup Tab==

This section allows you to assign the selected object to a [[VisGroup]] or remove it from one. To assign the objects to a VisGroup, simply select the VisGroups from the list. All selected objects will be assigned to the VisGroups you select. An object can be in any number of VisGroups. Pressing '''Edit groups''' opens the Edit VisGroups dialog. For more information on VisGroups, see [[Grouping and VisGrouping]].
