The value behind alias= is the (local) path to the property that has to be transmitted. Make sure that the local property has the same type as the generic MP enabled one (note that bools are automatically converted to integers so you can map an MP enabled int to a local bool). It is important to remember to not explicitly define the property type in an alias property. | (FIXME) The value behind alias= is the (local) path to the property that has to be transmitted.

The alias stuff apparently does not work. This would appear to be a bug. The consensus on the forum is that you have to use the sim/multiplay/generic/int[0] in your animations and then somewhere (in JSBSim as the output of a function for example) set sim/multiplay/generic/int[0] to the correct value for "/controls/lighting/landing-light-l". | |||

Alternatively this can be done without using nasal. Again in the model xml file: | |||
<params> | |||
<lighting> | |||
<landing-light-l> | |||
<property>sim/multiplay/generic/float[0]</property> | |||
</landing-light-l> | |||
</lighting> | |||
</params> | |||
Then in the animation use: | |||
<property alias="../../params/lighting/landing-light-l/property"/> | |||
