Releasing brakes will also release the parking brake; be aware that these are not two separate systems in X-Plane.

Additionally, many aircraft cannot turn directly deselect a mode without disconnecting the autopilot, so you may find that commands like heading hold off do nothing, depending on the aircraft.

Custom programming is required for most aircraft for these commands to work, so they are not reliable.

This can be problematic when you try to map two, three or even more of these switch states to very similar coordinates on your device image.

You can confirm it worked by hitting the Reset to Defaults for device button and confirming that none of your axis or button assignments changes.

If the very center of that image corresponds to a particular button, wed put a line in the.joy file to the effect of Button x should be labeled at position (500, 500).

Well get to the actual syntax below.).

So, youll specify the coordinates for these things in pixels, with (0, 0) in the upper left of the image.

A new line will appear in the source at the bottom of the window, giving you the coordinates of that shape.

While there are no official size limits, we recommend the image be no larger than 20002000 pixels to avoid impacting sim performance.

X-Plane will also scale large images automatically while maintaining the image map coordinates you specify.

Button button index (label for UI): x coordinate in the image y coordinate in the image.

Axis Group (label for this group, displayed in the UI): 1st axis index in this group 2nd axis index.

Axis index (xyz): x coordinate in the image y coordinate in the image.

Hat Switch hat switch number Direction hat switch direction: command path, like simoperationquit.

In that case, you can mark the control as hidden in the Assignments section (see examples above).

Doing so will cause X-Plane to ignore that phantom control entirely, and not show it anywhere in the app.

For instance, if youre a custom cockpit builder, and your axis reports 16 bits of travel, but you only use 10 bitsduring calibration, X-Plane may never recognize the range of motion as complete, although you know it is.

By default, X-Plane only recognizes one as a hat switch and the rest are considered separate buttons.

You can group a set of 4 buttons into a virtual hat switch, which can make the button image mapping cleaner and easier to understand.

When the switch is in one of these two positions, it sends a perpetually held button press, and while its in the other position, it sends no button press at all.

The engine toggles on the Warthog are like this: ignition is momentary, normal is center, and motor is the toggle-and-hold.

When a button is marked as momentary, X-Plane will only run the associated command on the initial down-press, rather than running the command continuously for as long as the button is down.

Likewise, virtual buttons are triggered when a real button (i.e., a button that you see in the UI when you have no.joy configuration file) is pressed or releasedyou pick which.

Likewise, it requires a press-and-release when the button is released (i.e., when the switch transitions to the off state).

In the rest of the file, you can refer to Button 100 as though it were perfectly normalyou can map it to a view, assign a default command to it, etc.
