The real world is full of motion. To simulate this in [[FlightGear]], '''models must be animated'''. | |||
This document provides basic information for all kind of animations. For more complex animations, you are advised to check the available [[aircraft]] for examples. | |||
==Special code parts== | |||
===Axis=== | |||
An axis part is required in every animation that involves a rotating or moving thing. | |||
<axis> | |||
<x>0</x> | |||
<y>1</y> | |||
<z>0</z> | |||
</axis> | |||
The axis are similar to the ones of the 3D model. There is a difference between rotation and translation: | |||
* In rotation animations, the axis part defines around what axis the object rotates. Negative/positive values make the difference between counterclockwise and clockwise rotations. | |||
* In translate animations, the part defines along what axis the object moves. If the x-axis is poiting backwards, an x-value of -1 will result in forward motion. | |||
===Center=== | |||

<x-m>-1.50</x-m> | |||
<y-m> 1 </y-m> | |||
<z-m> 0.25</z-m> | |||
<nowiki></center></nowiki> | |||
The axis are similar to the ones of the 3D model, so finding coordinates is easily done in 3D modeling software. | |||

The same as [[#Textranslate|textranslate]], but this animation moves a whole object (so including fixed textures). The example below will move an object 5 meters in the y-direction. | |||
