<p>You have three ways to play with the AI view distances. They all work at
|
||
|
|
the same time, so a character's vis value is: Lua * Foliage * Region</p>
|
||
|
|
<hr>
|
||
|
|
<p></p>
|
||
|
|
<p><strong>Lua Vis Factor</strong></p>
|
||
|
|
<p>You can set the overall view distance in the level lua:</p>
|
||
|
|
<pre> SetAIViewMultiplier(0.45)
|
||
|
|
</pre>
|
||
|
|
<p>
|
||
|
|
That means that over the entire level, AI can see 45% as far as normal.

<p>
|

</p><p><strong>Foliage Vis Factors</strong></p>
|
||
|
|
<p>You can set visibility modifiers on foliage, which, for example, allows you
|
||
|
|
to hide inside bushes on endor. Do this by adding a line into the .prp
|
||
|
|
(foliage prop file) for the level. As an example, here is layer from the endor
|
||
|
|
prop file ("worlds/end/world1/end.prp"):</p>
|
||
|
|
<pre>Layer(1)
|
||
|

{

|

File("end_prop_treeclump_1.msh", 50);

</pre>
|

|
|
<p>The two red lines should be added. You can adjust the visibility per model, with
|
||
|
|
a value for crouching and standing.</p>
|
||
|
|
<p>The first means that for the foliage model "end_prop_fern5", you will
|
||
|
|
be 70% visible from AI if you're crouched inside it, but 100% visible if
|
||
|
|
standing inside it.
|
||
|
|
</p>
|
||
|
|
<p>The second model ("end_prop_treeclump_1") will give you 35% visibility when
|
||
|
|
crouched, and 60% when standing.</p>

<p><strong>AI Vis Regions</strong></p>
|

|
|
<p><img src="AI%20Visibility_files/aivisregion.jpg" width="393" height="341" align="right"> AI

Visibility Regions allow you to set regions in the world editor that affect the
|
||
|
|
AI's visibility of anything inside that region. Vis Regions work on both
|
||
|
|
players and AI, but not so well on vehicles.
|
||
|
|
</p>
|
||
|
|
<p>To make them in the editor, create a new region and hit the "Change Type" button
|
||
|
|
to select the type "AIVis".
|
||
|
|
</p>
|
||
|
|
<p>Then set the vis multipliers for crouch and stand. These are a multiplier
|
||
|
|
on normal visibility, so 0.5 means that you're 50% covered, while 2.0 would
|
||
|
|
mean that you're visible twice as far away as normal.</p>
|
||
|
|
<p>You can only be inside one vis region at a time, so if the regions overlap, it
|
||
|
|
will randomly pick one of them and use that value. This is fine as long
|
||
|
|
as the overlapping regions all have the same values.</p>
