====How do the library based Checks and Execs work?====

===Check values of different types of libvars===
There are different kind of libvars which can have different kind of values.

Libvar Types: Commanders, Historical Unit, Historical Model, LandscapeType, etc...

ValueTypes: numeric, text, regime slot#, people slot#, sftype slot#, etc..

These functions are really usefull when creating event libraries. As you can create libvars in the libvar tab of the advanced editor and allow end users of the Simple Editor to set their values. Then your scripts here can read the values set by the Simple Editor user. 

==CheckLibVarCommander==
parameters: historical unit slot#, library Name, variable Name

returns: value of libvar

==CheckLibVarHex
parameters: x, y, library Name, variable Name

returns: value of libvar

==CheckLibVarSFType==
parameters: sftype slot#, library Name, variable Name

returns: value of libvar

==CheckLibVarLocType==
parameters: locationtype slot#, library Name, variable Name

returns: value of libvar

==CheckLibVarRoad==
parameters: roadType slot#, library Name, variable Name

returns: value of libvar

==CheckLibVarRiver==
parameters: riverType slot#, library Name, variable Name

returns: value of libvar

==CheckLibVarPeople==
parameters: people slot#, library Name, variable Name

returns: value of libvar

==CheckLibVarRegime==
parameters: regime slot#, library Name, variable Name

returns: value of libvar

==CheckLibVarLandscape==
parameters: landscapeType slot#, library Name, variable Name

returns: value of libvar

==CheckLibVarHistorical==
parameters: historical unit slot#, library Name, variable Name

returns: value of libvar

==CheckLibVarGlobal==
parameters: library Name, variable Name

returns: value of libvar

===Check the slot# or ID# of a specific library imported data instance===

Your event library might be trying to access data of other libraries for example. Its best not to use these and use your own libvars to ask the Simple Editor user to supply whatever information you need.

Like for example if you are writing a partisan event library you might want to have global or regime libvars asking the Simple Editor user to tell you the historical unit model to use when placing partisan units.

==CheckGetEventPic==
parameters: library Name, event picture Id# as set in library

returns: returns event picture slot#

==CheckGetCardByLibrary==
parameters: library Name, card Id# as set in library

returns: returns actioncard slot#

==CheckGetPeopleByLibrary==
parameters: library Name, people Id# as set in library

returns: returns people slot#

==CheckGetSFTypeByLibrary==
parameters: library Name, sfType Id# as set in library

returns: returns sfType slot#

==CheckGetPreDefByLibrary==
parameters: library Name, unit PredefId# as set in library

returns: returns unit predef ID# in our scenario

==CheckGetEventByLib==
parameters: library Name, event Id# as set in library

returns: returns event slot#

==CheckGetHistoricalIDByLib==
parameters: library Name, historical unit ID# as set in library

returns: returns historical unit ID# in our scenario

==CheckGetHistoricalIdForCommanderByLib==
parameters: library Name, commander ID# as set in library

returns: returns historical unit ID# in our scenario

==CheckGetSmallPic==
parameters: library Name, smallGfx Id# as set in library

returns: returns smallGfx slot#


===Misc. checks related to libraries===

==CheckGetCardLib==
parameters: cards slot#

returns: returns name of library

===The following Execs are available:===

==ExecSetLibVar==
parameters: library name, variable name, variable value

effect: changes or adds the variable

==ExecSetHisLibVar==
parameters: library name, historical unit slot#, variable name, variable value

effect: changes or adds the historical libvar variable

==ExecSetHexLibVar==
parameters: library name, variable name, variable value

NB: You need to call SetCardXY(x,y) to specify the hex you want to edit the libvar of.

effect: changes or adds the historical libvar variable of the specified hex.

==ExecAllFunctionByLibrary==
parameters: library name, event name

effect: executes stated event. 

NB: more safe than the ExecCallFunction which could pose a problems if end user would have loaded another event library using an event with exactly the same name.
