Sending several commands in X-Plane

[frumpy]

Hey,

I am using the main monitor for displaying the 3D-cockpit and sometimes just the outside view. The outside view requires me to call the "zoom_in"-command 15 times, so it looks halfway realistic. I could set the default viewing angle in X-Plane to match either the internal, or external view. So the default angle is set to the 3D-cockpit.

So when I use the 2nd G1000 screen and show the external world on the the big screen, I need to send those commands. Easy, I thought, just send it 15 times in a row when pressing a button via Arduino.
But no, only one command arrives at X-Plane, the other 14 get lost. Afaik a timer in X-Plane is not possible.

So how to solve this? Wait for next frame generation and send single commands, until 15frames/commands are finished?

Or is there a better way of doing this?

Thanks, Olli

Isn't there a dataref for this to set? Sounds much easier and accurate.

Hi,
Post some code of what you want to do, Remember to include any images if used.

It's a larger gauge for controlling a G1000. I load it up with every plane, as I am able to control course, heading and autopilot stuff also on non G1000 planes. Like a general gauge

I did not find any dataref on the actual zoom factor.

Also, on my 3440*1440 screen I'd like to set the vertical and horizontal viewing angle manually, but I can't do so via dataref. Setting things up in 3D cockpit view means a distorted picture in outside view with 15x zoom pressed (and vise versa).

Hi,

You going to learn something else new today.
Just a few lines does what you want, You can use the fast or slow option. Anyway here are some options. you can play with them to get your desired result.

Code: Select all

hw_button_add("Zoom In Button", function()
    xpl_command("sim/general/zoom_in_slow", "BEGIN")
end,
function()
    xpl_command("sim/general/zoom_in_slow", "END")
end)
--------------------
hw_button_add("Zoom out Button", function()
    xpl_command("sim/general/zoom_out_fast", "BEGIN")
end,
function()
    xpl_command("sim/general/zoom_out_fast", "END")
end)
-----------------------------
hw_button_add("Zoom In Button2", function()
   for i = 0,14 do
    xpl_command("sim/general/zoom_in")
   end
end)

Thanks Keith, I appreciate it! I like LUA. Gets me into a flow to do stuff and try new things. Also with X-Plane, much easier to interface and do tricks than with other sims.

The for..to-loop does not reach X-Plane, only a single command gets there.

The _fast-command works - however, it very much depends on how long I press the button. So depending on my state of being, it turns out a different zoom factor each time.


I want to drive 2 setups with the sim, one for casual flying in standard 3D-cockpits and one for the homecockpit-setup with the external G1000. For each setup I need a certain vertical/horizontal viewing angle plus a zoom factor.
I want it standardized, press a button once and everything will be setup is set up correctly.

What I found, is that there is no dataref for the zoom. But there are two datarefs to drive horizontal and vertical viewing angle:

sim/graphics/view/vertical_field_of_view_deg
sim/graphics/view/field_of_view_deg

Basically by setting vertical and horizontal angles I control viewing ratio and zoom. I found 98/50.5 deg work well for 3D, and 71/35 look good for the homecockpit view on my 21:9 screen.

I'll try more and report

I did not find any dataref on the actual zoom factor.

The zoom is handle internally with those read-only datarefs, so nothing we have hands on :

Code: Select all

sim/graphics/view/projection_matrix_3d
sim/graphics/view/world_matrix

Hi,

Yes for loop does send 15 commands and works. However if you have sent a "BEGIN" either in the sim or via AM it will not work. To overcome this issue we send a "END" command before we do the for loop.
You are aware that you can subscribe to a command? So in the code supplied below I have included a subscribe to check if the commands are in fact being sent multiple times.
Try this code and let me know.

Code: Select all

hw_button_add("Zoom In Button2", function()
   xpl_command("sim/general/zoom_in","END")
   for i = 0,14 do
    xpl_command("sim/general/zoom_in")
   end
end)

nn=""
xpl_command_subscribe("sim/general/zoom_in",function(n)
 nn=n
 print(nn)
 end))

Thanks, I was able to solve the issue in the meantime. So here is what I come up with:

https://youtu.be/dFY8cmTesdk

Code: Select all

 xpl_dataref_write("sim/graphics/view/field_of_view_deg", "FLOAT", 98.0)
 xpl_dataref_write("sim/graphics/view/vertical_field_of_view_deg", "FLOAT", 50.5)

As for sending the 15 commands, thanks for the code. I stumbled upon the same issue a few years ago, so it might be handy in the future.
