Right now the code is not very configurable, and there is only one submodel per airplane possible. It is implemented as an SGSubSystem, just like the electrics, vacuum, etc. systems. To make it work you need to make a release binding like this (for my joystick trigger):
<button n="0">
<desc>Trigger</desc>
<binding>
<command>property-assign</command>
<property>/systems/submodel/trigger</property>
<value type="bool">true</value>
</binding>
<mod-up>
<binding>
<command>property-assign</command>
<property>/systems/submodel/trigger</property>
<value type="bool">false</value>
</binding>
</mod-up>
</button>
Then, each airplane that uses the system should have something like this added to its *-set.xml file (note that this does *not* go within the <sim></sim> tags):
<systems>
<submodel>
<serviceable type="bool">true</serviceable>
<amount type="int">70</amount>
</submodel>
</systems>
Future improvements will include:
1) more configurability, so the user can create multiple submodels, and can assign them different locations, and pitch and yaw adjustments, and nitial velocity.
2) sound?
3) a more accurate calculation of the submodels location at any pitch/roll/yaw.
4) a way to pre-load the model, so the AI code doesn't have to parse the model every time it creates an instance.
I think that's all of it.
- Modified the rpm vs. suction formula to hit much more realistic numbers.
We should be seeing just over 4 inhg at idle and approaching 5 inhg at
full throttle.
The code reads the electrical system config and contructs an internal model.
Nothing is done beyond that yet ... the electrical system is not updated,
nor is it connected to the property system in anyway.
