PDA decls are probably the easiest decl to understand because they are so simple.
|
|||
|
|
There is an editor for PDAs (<a href="editor_pda.html">editPDAs</a>) not because they are
|
|||
|
|
hard, but because they are tedious (especially when you are making 100 of them).
|
|||
|
|
|
|||
|
|
</p><p>
|
|||
|
|
A PDA is actually made up of multiple decls. There is the PDA itself, then there
|
|||
|
|
are the emails that go in the PDA, the Audio Logs, and the Videos. Note in vanilla
|
|||
|
|
Doom 3, the 'Personal' PDA is the only PDA that can contain videos, but it cannot
|
|||
|
|
contain any Audio Logs. If there is a video in a non-personal PDA, it gets copied
|
|||
|
|
to the Personal PDA when it is picked up. Doom 3 actually defines 'Personal PDA'
|
|||
|
|
to mean whichever PDA is picked up first, so it's up to the level designer to make
|
|||
|
|
sure the actual personal PDA is picked up before any others.
|
|||
|
|
|
|||
|
|
</p><p>
|
|||
|
|
Let's take a look at the PDA for James Holiday:
|
|||
|
|
</p><pre class="code">pda commoutside_holiday {
|
|||
|
|
name "James Holiday"
|
|||
|
|
fullname "James A. Holiday"
|
|||
|
|
icon "guis/assets/pda/icon_jholiday"
|
|||
|
|
id "7085-64"
|
|||
|
|
post "Communications Transfer"
|
|||
|
|
title "Transport Controller"
|
|||
|
|
security "COMM Transfer Access"
|
|||
|
|
pda_email "commoutside_holiday_email_1"
|
|||
|
|
pda_email "commoutside_holiday_email_2"
|
|||
|
|
pda_audio "commoutside_holiday_audio_1"
|
|||
|
|
}
|
|||
|
|
</pre>
|
|||
|
|
|
|||
|
|
<p>
|
|||
|
|
Pretty simple to figure out I hope. The icon is not actually used in Doom 3, but
|
|||
|
|
we were going to use it at one time. Everything in there is for display
|
|||
|
|
purpose only, which means if you change the 'security' key, it doesn't actually
|
|||
|
|
change your security clearance (it only changes what it <b>says</b> your security
|
|||
|
|
clearance is). Actual security clearance is defined by the presence or abscense of
|
|||
|
|
various items in your inventory.
|
|||
|
|
|
|||
|
|
</p><p>
|
|||
|
|
let's take a look at an email:
|
|||
|
|
</p><pre class="code">email commoutside_holiday_email_2 {
|
|||
|
|
date "11-15-2145"
|
|||
|
|
to "James Holiday"
|
|||
|
|
from "Shipping Authority"
|
|||
|
|
subject "Site 1 needs"
|
|||
|
|
text {
|
|||
|
|
"Blah blah, this is an email.\n\n"
|
|||
|
|
"Blah blah, this is line 2\n\n"
|
|||
|
|
"-Shipping Authority"
|
|||
|
|
}
|
|||
|
|
}
|
|||
|
|
</pre>
|
|||
|
|
|
|||
|
|
<p>
|
|||
|
|
The format for the email is pretty self explanitory. The biggest 'gotcha'
|
|||
|
|
(and the biggest reason to use the editor) is every line has to be in quotes, and you
|
|||
|
|
have to use \n to create new lines. That has been the biggest reason for PDAs to break
|
|||
|
|
during Doom 3 development.
|
|||
|
|
|
|||
|
|
</p><p>
|
|||
|
|
Now let's look at the audio log:
|
|||
|
|
</p><pre class="code">audio commoutside_holiday_audio_1 {
|
|||
|
|
name "Artifact Transport Concerns"
|
|||
|
|
info "Made by: James Holiday\nDate: 09-24-2145\nArchive: Yes"
|
|||
|
|
preview "sound/vo/video/novideo"
|
|||
|
|
audio "audiolog_commoutside_holiday_1"
|
|||
|
|
}
|
|||
|
|
</pre>
|
|||
|
|
|
|||
|
|
<p>
|
|||
|
|
Again, pretty self explanitory. The info and preview didn't end up getting used in the final
|
|||
|
|
build of the game, but at one time the gui showed little icons and info beside each audio log.
|
|||
|
|
Now all you really need is 'name' and 'audio'
|
|||
|
|
|
|||
|
|
</p><p>
|
|||
|
|
Next, let's take a look at the first video you get when you pick up your PDA:
|
|||
|
|
</p><pre class="code">video marine_sop {
|
|||
|
|
name "Marine Command Briefing"
|
|||
|
|
info "Creator: Marine HQ\nDate: 03/11/45\n\nOperating Procedures\n"
|
|||
|
|
video "video/video_marine_sops"
|
|||
|
|
audio "video_marine_sops"
|
|||
|
|
preview "guis/assets/cpuserver/uac.tga"
|
|||
|
|
}
|
|||
|
|
</pre>
|
|||
|
|
|
|||
|
|
<p>
|
|||
|
|
Again, info is just used for display. Preview is the image shown in the box before you hit 'play'.
|
|||
|
|
Video is the material to use after you hit play (technically it can be any material, but a material
|
|||
|
|
with a roq in it makes the most sense). Audio is the sound to play in sync with the video.
|
|||
|
|
|
|||
|
|
</p><p>
|
|||
|
|
Videos can be attached to video discs by setting the 'video' key on an 'item_videocd' entity.
