'''Universal MMU''' or '''UMMU''' for short is an [[add-on]] [[SDK]], which allows addon developers to easily implement a crew simulation for an addon vessel. '''UMMU''' compatible vessels are capable of [[EVA|EVAs]] and crew transfer with other '''UMMU''' vessels. '''UMMU''' was based on the crew management system developed by Dansteph for the [[DeltaGliderIV]] project. "MMU" in real life stands for [http://en.wikipedia.org/wiki/Manned_Maneuvering_Unit Manned Maneuvering Unit].

==Universal MMU==

A '''Universal MMU''' is a special vessel class designed by Dansteph to simulate an astronaut crew when on [[EVA|EVAs]]. Each individual '''UMMU''', when EVAed from a vessel or created through the scenario editor, is equipped with an idividual set of individual RCS thrusters for use in space as well as the ability to "walk" on the surface of a celestial body (not consuming any fuel in that case). Each '''UMMU''' has three [[attachment points]], one parent->child for grappling objects, another parent->child for installing special backpacks, called "TurboPacks", with the identifer "TurboMmu". The third is a child->parent attachment point and has the type identifier "GRAPME". These [[attachment points]] allow '''UMMU''' crew to simulate grappling objects such as space station modules, UCGO cargo crates, and any other object with the appropriate attachment ID in its configuration file.

==Features==

* Astronaut meshes can be customized
* '''UMMU''' crew on [[EVA|EVAs]] consume Oxygen and can die of suffocation, crashes, oxygen deprivation and high temperatures such as those in atmospheric reentry. 
* Each '''UMMU''' is equipped with a [[w:Parachute|parachute]] particularily useful when falling in Earths atmosphere. A [[w:Jetpack|jetpack]] ("Turbopack") is also available for greater mobility during various types of [[EVA|EVAs]]. 
* All MMUs support a built-in help system, available by pressing {{Key|H}} while controlling a '''UMMU'''. 

==Universal MMU SDK==
The '''UMMU''' package comes with a [[SDK]] for addon developers, which can be found in the example contained in the documentation folder(".\Doc\UMmu_SDK\UMmu_ShuttlePB_Example"), as well as the PDF documentation itself. The library "UMmuSDK.lib" is linked against the 2005 version of visual C++, which means that VC6 users need to include the VC2005 Express standard libraries instead of the VC6 standard libraries. A modified [[Shuttle PB]] compiled to include '''UMMU''' is included as example to help explain use of the addon.

===Limitations===
* Astronauts can only start an EVA when the primary docking port is not used.

==Distribution==

End users are not allowed to redistribute the '''UMMU''' libraries and modules in their addon projects. This helps to avoid redistribution of outdated UMMU libraries & files, '''UMMU''' being updated with some regularity allowing Dansteph to correct errors & add new functionality to the addon. 

Also, the '''UMMU''' license demands that full compatibility with the included SDK is necessary for add-ons to list it as relying on. This was intended to prevent addon developers unable to include UMMU support in their projects from listing '''UMMU''' as a requirement when their scenarios only include UMMUs to make it appear '''UMMU''' compatible.

==Current Addons supporting UMMU==
* [[DeltaGliderIV]]
* [[PreludeII]] base, included as part of the DeltaGliderIV add-on package.
* [[DeltaGlider-XR1]]
* [[XR5 Vanguard]]
