===3 axis ''locked-track'' animation=== | |||
If it is necessary realize the animation to an object with ball joint, is the typical case of a hydraulic jack actuate the opening the landing gear, it is necessary to proceed in two stages, '''as ''locked-track'' animation always needs at least a locked axis'''. | |||
First locks, for example, the '''Y''' axis and directs the object to a target object, in this example '' BOX_GEAR_GREEN.000 '' with coordinates: '' target-center ''. The '' track-axis '' is the axis that should point the target: | |||
<syntaxhighlight lang="xml"> | |||
<?xml version="1.0" encoding="utf8"?> | |||
<animation> | |||
<type>locked-track</type> | |||
<object-name>gear-front-jack-02</object-name> | |||
<center> | |||
<x-m>-2.91953</x-m> | |||
<y-m>-0.06230</y-m> | |||
<z-m>-1.30829</z-m> | |||
</center> | |||
<lock-axis> | |||
<x>0</x> | |||
<y>1</y> | |||
<z>0</z> | |||
</lock-axis> | |||
<track-axis> | |||
<x>1</x> | |||
<y>-0.23</y> | |||
<z>0.630</z> | |||
</track-axis> | |||
<target-name>BOX_GEAR_GREEN.000</target-name> | |||
<target-center> | |||
<x-m>-2.04543</x-m> | |||
<y-m>-0.23232</y-m> | |||
<z-m>-0.82533</z-m> | |||
</target-center> | |||
</animation> | |||
</syntaxhighlight> | |||
Then write a second ''locked-track'', which should be put immediately under the first, which locks the axis '''X'''. Everything else is equal, as all other references are unchanged. | |||
