<h1>Appendix A: usage of targetShaderName and targetShaderNewName</h1>
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
The targetShaderName and targetShaderNewName keys can be used with any entity
|
|
|
|
|
that supports the target key (the entity instance does not actually have to use
|
|
|
|
|
the target key for these new keys to work). If both are defined, then when the
|
|
|
|
|
entity decides to activate its targets, all shaders/textures in the map that
|
|
|
|
|
were originally the same name as the targetShaderName value, will be changed to
|
|
|
|
|
the targetShaderNewName value.
|
|
|
|
|
</p>
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
For example this would make it look like the red light shader is "turning on":
|
|
|
|
|
</p>
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
"targetShaderName" "textures/proto2/redlight_off"<br>
|
|
|
|
|
"targetShaderNewName" "textures/proto2/redlight_on"
|
|
|
|
|
</p>
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
And this would turn it back off:
|
|
|
|
|
</p>
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
"targetShaderName" "textures/proto2/redlight_off"<br>
|
|
|
|
|
"targetShaderNewName" "textures/proto2/redlight_off"
|
|
|
|
|
</p>
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
Note that the ORIGINAL shader name is used in both instances, not whatever it
|
|
|
|
|
happens to be currently. Also, of course, this will happen globally. If the
|
|
|
|
|
mapper wanted to affect only a certain set of red lights, he/she would need to
|
|
|
|
|
make a unique shader name to be used with that set.
|
|
|
|
|
</p>
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
The code that supports these keys is in G_UseTargets in g_utils.c.
|
|
|
