===Move dynamically the procedural light=== | |||
The position of a procedural light is declared in the '''<model>''' section, within the '''<PropertyList>''' XML code, for example: | |||
<syntaxhighlight lang="xml"> | |||
<model> | |||
<name>procedural-light-gear-white-left</name> | |||
<path>Effects/lights/procedural_light_gear_white.xml</path> | |||
<offsets> | |||
<x-m> -3.08</x-m> | |||
<y-m> -0.21 </y-m> | |||
<z-m> -1.18 </z-m> | |||
</offsets> | |||
</model> | |||
</syntaxhighlight> | |||
The '''<model>''' statement is itself an object, it can be inserted directly as an object of an animation, for excample, some line after is it possible to insert this code: | |||
<syntaxhighlight lang="xml"> | |||
<animation> | |||
<type>rotate</type> | |||
<object-name>GearFrontalDoor</object-name> | |||
<object-name>procedural-light-gear-white-left</object-name> | |||
<property>gear/gear/position-norm</property> | |||
<axis> | |||
<x1-m> -3.00240</x1-m> | |||
<y1-m> 1.0</y1-m> | |||
<z1-m> -1.02906</z1-m> | |||
<x2-m> -3.00240</x2-m> | |||
<y2-m> -1.0</y2-m> | |||
<z2-m> -1.0290</z2-m> | |||
</axis> | |||
<interpolation> | |||
<entry><ind>0.0</ind><dep>90</dep></entry> | |||
<entry><ind>0.25</ind><dep>90</dep></entry> | |||
<entry><ind>0.50</ind><dep>60</dep></entry> | |||
<entry><ind>0.75</ind><dep>30</dep></entry> | |||
<entry><ind>1.0</ind><dep>0</dep></entry> | |||
</interpolation> | |||
</animation> | |||
</syntaxhighlight> | |||
The declaration therefore defines a ''procedural light'' object: | |||
<syntaxhighlight lang="xml"> | |||
<object-name>procedural-light-gear-white-left</object-name> | |||
</syntaxhighlight> | |||
