== Creating a Checkpoint Room ==

[[Image:l4d_hammer_checkpoint_09.jpg|thumb|right|500px|caption|Building the room for the checkpoint.]]

Now, let's create the checkpoint room. Using the duplication of brushes technique you used in the first tutorial, create a room on the other side of the checkpoint door with these dimensions:

* 256 Units Wide
* 384 Units Long
* 128 Units Tall

{{warning:ru|Be careful not to duplicate the <code>func_detail</code> brush that was used for the platform or your level will "[[leak]]" to the outside. All of your outer walls, floors and ceilings need to be regular world (non-entity) brushes.}}

Also, remember to duplicate one of the lights into this new room so it will be lit.

{{clr}}

[[Image:l4d_hammer_checkpoint_10.jpg|thumb|right|500px|caption|Creating a brush inside the checkpoint room.]]

Now, we need a brush entity called an <code>info_changelevel</code>.

Go to the {{Hammer block}} and draw a brush that fits inside your newest room.

{{clr}}

[[Image:Toolstrigger.gif|left]]
[[Image:l4d_hammer_tie_to_entity.jpg|thumb|right|500px|caption|Selecting Tie to Entity from the Tools menu.]]

Click on the '''Browse''' button on the '''Texture''' bar to bring up the '''Texture Browser'''.

Type "trigger" in the '''Filter''' drop-down field.

Select the texture "<code>tools\toolstrigger</code>"

Double-click on the texture to make it the current texture.

Click on the [[Image:Hammer_ApplyCurrentTexture.png]] '''Apply Texture''' on the Tool Bar to apply it to the brush.

<br />

With the brush still selected, select '''Tools''' > '''Tie to Entity''' (or press {{key|CTRL}}+{{key|T}}).

This will bring up the '''Object Properties''' dialog box.

{{clr}}

[[Image:l4d_hammer_checkpoint_12.jpg|thumb|right|500px|caption|The info_changelevel properties.]]

In the '''Class''' drop-down menu, choose "<code>info_changelevel</code>" and click '''Apply'''.

Click on the '''New Map Name''' row and change add the text "<code>tutorial05_part2</code>" in the field at the right.

Click on '''Apply''' and close the dialog box.

{{note|The <code>info_changelevel</code> is a brush entity that will transition the players and the <code>prop_physics</code> entities inside it to the destination level (given in the '''New Map Name''' field).}}

{{clr}}

[[Image:l4d_hammer_checkpoint_13.jpg|thumb|right|500px|caption|Placing an info_landmark entity.]]

Click on the {{Hammer entity}} and select "<code>info_landmark</code>" from the '''Objects''' drop-down menu.

Place it in the middle of your new room. Make sure you snap the entity to the exact middle as shown in the image.{{clr}}

[[Image:l4d_hammer_checkpoint_14.jpg|thumb|right|500px|caption|The info_landmark properties.]]

Open up the '''Object Properties''' for the <code>info_landmark</code> ({{key|Alt}}+{{key|Enter}}).

Change the '''Name''' to "<code>landmark_tutorial</code>". Click '''Apply''' and close the dialog box.

{{note|The <code>info_landmark</code> is an entity that exists in both the level that the player starts in and the level that the player transitions to. The <code>info_landmark</code> must be in the exact relative position to the surrounding world in both levels. So, you can move the <code>info_landmark</code> in the destination level, but you must move the geometry around it as well for the transition to work.}}

{{clr}}

[[Image:l4d_hammer_checkpoint_15.jpg|thumb|right|500px|caption|Using the eye dropper to grab an entity name.]]

Go back and click on the <code>info_changelevel</code> brush that you just created and bring up its '''Object Properties''' (you'll need to move in the '''Camera''' viewport to see the trigger texture on the brush to select it).

Click on the '''Landmark Name''' row and you'll see an eye dropper icon on the right side, next to the '''Mark''' and '''Mark+Add''' buttons. Click on the '''eye dropper''' icon.

{{clr}}

[[Image:l4d_hammer_checkpoint_16.jpg|thumb|right|500px|caption|The result from the eye dropper.]]

With the dialog box still up, you can navigate in the '''Camera''' viewport to see the <code>info_landmark</code>. If you click on the <code>info_landmark</code> with the eye-dropper enabled, it will grab the name of the <code>info_landmark</code> and place it in the '''Landmark Name''' field for you.

{{clr}}

== Create the exit ==

[[Image:l4d_hammer_checkpoint_17.jpg|thumb|right|500px|caption|Placing the checkpoint door.]]

Just to get the next checkpoint area in the level that we'll be transitioning into set up, we'll place another checkpoint door that will be the exit in the next level.

Duplicate the checkpoint door you placed as the checkpoint entrance in this level and place it in the right wall of the checkpoint room. Rotate it so that it will be exited out through that wall.

{{clr}}

[[Image:l4d_hammer_checkpoint_18.jpg|thumb|right|500px|caption|Selecting the checkpoint door model.]]

Before we cut out the hole for it, let's edit its properties to be the exit door.

Click on the '''World Model''' row and click on the '''Browse''' button on the right side. Find the model "<code>checkpoint_door_01_static.mdl</code>" and click on the '''OK''' button.

{{clr}}

[[Image:l4d_hammer_checkpoint_19.jpg|thumb|right|500px|caption|Changing the checkpoint door to prop_static.]]

Change the '''Class''' to a <code>prop_static</code> since the door doesn't have to function like a real door.

Click on '''Apply''' and the close the dialog box.

{{clr}}

[[Image:l4d_hammer_checkpoint_21.jpg|thumb|right|500px|caption|The cutout for the checkpoint door. The adjoining wall is 48 units long.]]

Using the [[Image:Hammer_ClippingTool.png]] '''Clipping Tool''' just like we did for the first checkpoint door, cut out a hole for this checkpoint door so that it looks like this image.

Note the connected wall next to the door should be '''48 units''' in length!

{{clr}}

[[Image:l4d_hammer_checkpoint_22.jpg|thumb|right|500px|caption|Sealing off the level behind the door.]]

Now, we have our checkpoint room, but there's still a leak to the outside world where this door is. We will need to seal it.

Duplicate the wall that the door is set in and move it behind the door so that it completely closes off the hole that the door creates.

Click on the '''Browse''' button in the '''Texture''' bar and type "<code>tools</code>" in the '''Filter''' drop-down field.

Find the texture "<code>tools/toolsblack</code>" and double-click on it to close the browser and make it the current texture.

Click on the [[Image:Hammer_ApplyCurrentTexture.png]] '''Apply current texture''' icon to make the brush black. This is so that the player won't be able to see out of the window in the checkpoint door.

Save your level with {{key|Ctrl}}+{{key|S}}.

You've now created a checkpoint room that will lead to another level called "<code>tutorial05_part2</code>". Now, we'll need to make that level so that we can test the transition.

{{clr}}

== Creating a Destination Level ==

First, make sure you've saved your work on tutorial05.vmf by choosing '''File''' > '''Save''', or press {{key|Ctrl}}+{{key|S}}.

Next, we'll make the destination level based on the current one.

Do '''File''' > '''Save As...''' and change the name the file "<code>tutorial05_part2.vmf</code>".

{{clr}}

[[Image:l4d_hammer_checkpoint_39.jpg|thumb|right|500px|caption|Moving the info_survivor_position.]]

Select the <code>info_survivor_position</code> in the starting room.

Move him to the middle of the checkpoint room.

{{clr}}

[[Image:l4d_hammer_checkpoint_23.jpg|thumb|right|500px|caption|Selecting the hallway from the first map.]]

Scroll out so that you can see your whole map in the '''Top''' viewport.

Select the hallway that you created in the first tutorial. You can left-click and drag across the center of the hallway to select all the brushes there.

{{clr}}

[[Image:l4d_hammer_checkpoint_24.jpg|thumb|right|500px|caption|Moving the hallway to the new position.]]

Move the hallway so that it lines up outside the checkpoint door on the bottom right side of the level. You can move the brushes by using the arrow keys or by left-clicking and dragging inside the selection box to the position you want the brushes to be in.

{{clr}}

[[Image:l4d_hammer_checkpoint_25.jpg|thumb|right|500px|caption|Raising the hallway brushes.]]

Then, move the hallway up so that the floor matches the floor of the checkpoint room.

{{clr}}

[[Image:l4d_hammer_checkpoint_26.jpg|thumb|right|500px|caption|Deleting the first room.]]

Now, let's get rid of the parts of the first level that we don't need.

Select the first room and then press the {{key|Delete}} key.

{{clr}}

[[Image:l4d_hammer_checkpoint_27.jpg|thumb|right|500px|caption|Deleting the second room.]]

Select the second room but '''don't include the shared wall with the checkpoint'''. If you select too much, just hold down {{key|Ctrl}} and click on any object to de-select. When you're done, press the {{key|Delete}} key.

{{clr}}

[[Image:l4d_hammer_checkpoint_28.jpg|thumb|right|500px|caption|Selecting the black brush.]]

Now, we need to move the black brush that we used to seal the first level so that it seals this level.

Select the black brush.

{{clr}}

[[Image:l4d_hammer_checkpoint_29.jpg|thumb|right|500px|caption|Moving the black brush to seal the new level.]]

Move it and shape it to cover the other doorway of the checkpoint room.

{{clr}}

[[Image:l4d_hammer_checkpoint_30.jpg|thumb|right|500px|caption|Creating the second room for the new map.]]

Duplicate the wall, ceiling and floor brushes from the hallway to make a new room at the end.

You'll need to make it these exact dimensions for the pre-generated navigation file to work:
* Width: 512
* Length: 480

Add a <code>light</code> to the middle of the room. You can duplicate the light in the checkpoint room and move it over.

{{clr}}

[[Image:l4d_hammer_checkpoint_31.jpg|thumb|right|500px|caption|Selecting the checkpoint door model.]]

Go to the checkpoint room and click on the door that led into the room from the previous level.

Press {{key|Alt}}+{{key|Enter}} to bring up the properties.

Click on the '''World Model''' row and click on the '''Browse''' button.

Select the model "<code>checkpoint_door_02_static.mdl</code>"

Click on '''OK'''.{{clr}}

[[Image:l4d_hammer_checkpoint_32.jpg|thumb|right|500px|caption|Changing the checkpoint door to a prop_static.]]

Change the '''Class''' to a "<code>prop_static</code>" since this door will no longer need to open or close.

Click on '''Apply''' to make the changes appear.

{{clr}}

[[Image:l4d_hammer_checkpoint_33.jpg|thumb|right|500px|caption|Selecting the checkpoint door model.]]

Select the other door in the checkpoint room – the one that will lead out of it.

Press {{key|Alt}}+{{key|Enter}} to open the properties.

Click on the '''World Model''' row and click on the '''Browse''' button.

Select the model "<code>checkpoint_door_01.mdl</code>"

Click on '''OK'''.

{{clr}}

[[Image:l4d_hammer_checkpoint_34.jpg|thumb|right|500px|caption|Changing the checkpoint door to a prop_door_rotating_checkpoint.]]

Change the '''Class''' to a "<code>prop_door_rotating_checkpoint</code>"

Click on the '''Apply''' button to update the properties.

{{clr}}

[[Image:l4d_hammer_checkpoint_36.jpg|thumb|right|500px|caption|The prop_door_rotating_checkpoint properties.]]

Change the following fields:

* '''Name''': "checkpoint_exit"
* '''Body''': "1"
* '''Disable Shadows''': "Yes"

{{clr}}

[[Image:l4d_hammer_checkpoint_35.jpg|thumb|right|500px|caption|The Flags tab in the checkpoint door properties.]]

Now, click on the '''Flags''' tab and check the "'''Use closes'''" box.

Click '''Apply''' again and close the properties box.

{{clr}}

[[Image:l4d_hammer_checkpoint_38.jpg|thumb|right|500px|caption|Aligning the checkpoint door.]]

Keep the door selected.

In the '''Top''' viewport, move the origin of the door model to the bottom part where it touches the wall.

This will make the door rotate on this axis.

{{clr}}

[[Image:l4d_hammer_checkpoint_37.jpg|thumb|right|500px|caption|Selecting the info_changelevel brush.]]

In the '''Camera''' viewport, move just inside the door and look back into the checkpoint room to select the <code>info_changelevel</code> that you have leftover from the previous level.

Press the {{key|Delete}} key to remove it.{{clr}}

== Compile the maps ==

=== tutorial05_part2 ===
[[Image:l4d_hammer_checkpoint_40.jpg|thumb|right|300px|caption|The Run Map dialog box.]]

Press {{key|F9}} to open the '''Run Map''', but this time click the "'''Don't run the game after compiling'''" checkbox. Then press '''OK'''. This will compile the level, but won't run the game afterwards.

=== tutorial05 ===
When the level is done compiling, open up "<code>tutorial05.vmf</code>" again.

Press {{key|F9}} and uncheck the "'''Don't run the game after compiling'''" checkbox and press '''OK'''. This will start you in the tutorial05 map and allow us to test the transition to the tutorial05_part2 map.

{{note|Make sure you have the files "tutorial05.nav" and "tutorial05_part2.nav" in your left4dead/maps directory.}}
