We have already [[Basic Construction|created brushes]]. There is another side to them: the '''[[brush entity]]'''.

In this example, we will create a brush that acts as a sliding door. When the player touches the brush, it will rise into the air and allow passage.

== Construction ==
# Select the {{hammer block}} and create a new brush. 128×128×16 is a good size, but anything will do. {{tip|If Hammer’s grid is too large to get down to 16 units, press {{key|[}} or click '''Smaller Grid''' [[File:Hammer SmallerGrid.png|link=]] to scale it down. Never disable snapping unless you really, ''really'' need to!}}
# Move the brush to an entity (also known as “tying” to an entity) using {{key|Ctrl+T}} or the [[Hammer New Objects Toolbar#toEntity_(Ctrl+T)|toEntity]] button:<p>[[File:Hammer toEntityButton.png|border|Hammer toEntity button|link=]]</p>. {{tip| If you've unselected the brush you wish to tie the entity to you will need to reselect it otherwise the toEntity button will not work when you click on it}}
# This will bring up the [[Hammer Object Properties Dialog|Object Properties]] dialog:<p>[[File:Hammer object properties.png|400px|Object properties dialog]]</p> {{tip|If you need to access the dialog again later, select your brush and press {{key|Alt+Enter}}.}}
# Select [[func_door]] from the “Class” drop-down menu in the top left (you can search by typing into the box) and hit “Apply”.
# Near the bottom of the main “Keyvalues” list, find “Move Direction”. Either change its value to read “<code>-90 0 0</code>” or select “Up” from the drop-down list to the left of the black circle.
# Click “Apply” again, then close the Object Properties dialog.

You should now be able to compile your map and see the door working.

== Finishing ==
Open the [[Hammer Texture Browser|Texture Browser]] and [[Hammer Texture Browser#Filter|filter]] for “door”. Choose a material that you like and apply it to your brush as you would normally. You might also want to build a wall that connects the door to the edges of your map.

==Destroying==
To make a brush entity back into a regular one, select it and press {{key|Ctrl+Shift+W}}, or '''ToWorld''', right next to the ToEntity button you clicked earlier.
