IO32, SIOC et HVAR de MSFS

[fab]

Si vous comprenez le titre de ce sujet, c'est que vous cherchez comme moi à agir sur les boutons d'un GNS430, d'un G1000, d'un CDU et autre composant d'un avion MSFS ...

Le but étant d'avoir des switch sur une IO32, et de pouvoir les interfacer avec les instruments spécifiques des avions.

C'est chose faite avec l'utilisation des offset $3110 et $3114 de FSUIPC.
L'astuce est de déclarer dans FSUIPC une liste "d'event" que vous allez pourvoir déclencher par un script ...

Je prépare une vidéo tuto pour cela ...

Restez à l'écoute, je reviens ...

Super Fab...
Pourrais tu en profiter pour renseigner à un non-initié qui n'a pas MSFS, ce qu'est une variable HVAR, please.

Je sais, je sais... Je n'ai pas utilisé Google.

 

[fab]

Les Lvars, que je traduis par variables locales sont des variables specifique aux avions, les Hvar sont des déclencheur d'actions comme des appuies sur des touches du GPS ou CDU.

Une définition trouvée sur Google :

LVAR is a local variable in XML model behavior code. LVARs are defined by the developer and their name can be whatever you like.

(L:Hi_Im_A_local_variable,number)

SimVar is an A or E variable. Simvars are defined by the sim and allow the developer to read the values of the aircraft and environment variables.


HVAR is a HTML variable. These are used in XML model behavior code to trigger an event in a HTML gauge.

Merci Fab...
Pour les LVARs, je connais bien depuis FSX.
Par contre, pour les HVARs, n'ayant pas le produit, je ne voyais pas à quoi cela pouvait faire référence.

En attendant ma vidéo tuto, pour votre culture générale, je vous laisse découvrir un extrait de la doc du SDK de MSFS...

Spoiler: Types de variables et leur préfixe

Variable Prefix	System Name	Description	Units
A​	Simulation Variable	Gets a specified SimVar from a simulation object.	Yes
B​	Input Events	Gets the value of the specified input event (see Input Event Definitions for more information).	No
C​	Callback Variables	This variable prefix is only used when dealing with GPS Variables.	Yes
E​	Environment Variable	This is an environment variable. See the section on Environment Variables, below.	Yes
F​	Function Library	This denotes a built in function from the function library. See the Function Library section below for more details.	No
G​	Gauge Variables	Gets a variable that can be used to transfer unitless data between gauges.	No
H​	HTML Event	An HTML event sent to the JavaScript. These are defined in cockpit panel Model Behaviors, and only go in one direction: from the panel to the JavaScript / HTML code. H: events are not required to be defined ahead of time (similar to L: vars) and can be named with any contiguous string of alphanumeric characters. Each cockpit panel in Microsoft Flight Simulator sends a number of cockpit specific H: events that have no analogous key event, such as pressing individual buttons on an FMS computer. These individual panel specific events can be received by JavaScript instruments.	No
I​	Instrument Variable	Used for variables within components, where the variable scope is the component and it's children.	No
K​	Key Event ID	This is a specific variable for a key Event IDfor user input. (>K:TOGGLE_ICS) Note that some key events require one or more values to be sent, so please see the section SimVars And Keys for more information on this.	No
L​	Local Variable	Retrieves and/or creates a user defined local variable. If the local variable has not been defined in any of the associated files then it will be created and set to 0 the very first time it is referenced (and will not persist between runs). You can, however, define a default value for local variables using the following files: using the [LocalVars.N] section of the FLT file you can define a non-persistent local variable using the [LocalVars] section of the Systems Config file you can create a persistent local variable This variable can be read and set within the scope of the user aircraft, and can be read by AI Aircraft. IMPORTANT! "L:" vars can only hold numeric data and nothing else, eg: no strings, no binary values, no structs, etc...	No
M​	Mouse Variable	Gets the state of the mouse for use in mouse click handlers. Please see the Mouse Variables section below.	No
O​	Component Variable	Used for variables within components, where the variable scope is the component itself.	No
P​	Program Variable	Same as the Environment Variable E:	Yes
R​	Resource Variable	This is used to retrieve a value from an external resource, which can either be a legacy Help ID or Tooltip ID, or something from a custom localization file. See Resource Variables for more details.
X​	Calculator Variable	This variable is used exclusively when creating Mission Definitions and is for referencing parameters created in the <CalculatorParameterList> element within an RPN calculation (inside a <CalculatorFormula>).	No
W​	Wwise Event	This is a Wwise Event ID and allows you to trigger a Wwise event based on logic driven by the XML. This makes it more flexible than the sounds defined in sound.cfg and the AnimSoundEvents, although more complex to use.	No
Z​	Custom SimVar	These are user-defined variables which are stored in an object's sim. The variable name is not one that has been predefined in the Microsoft Flight Simulator engine code, so anyone can create one with the name they want, as long as it doesn't conflict with an existing SimVar.	No
