How to check if player lowered the CH-47 loading ramp?

[sirrah]

Does anyone know if it's possible to add a trigger condition that checks if the CH-47 ramp has been lowered?

Can this perhaps be done with a "cockpit parameter equal to" condition? And if so, could anyone please share the values that should be used for that parameter?

IIRC it can be done, and requires an IMHO excessively tedious process involving the model viewer, finding the model (which is not always named as you'd think), going through all possible accessible elements, noting the stage, and then trying this in ME. With some luck, it is supported. I'd rather choke and would prefer that ED give us that info in some kind of spreadsheet after we shelled out some 50 bucks or more fore the model.

Hm ok, that doesn't at all sound appealing to dive into, for my "simple" mission 

Was kinda hoping for some simple parameter, like we use to check if a player has tuned to the correct radio freq.

Too bad..

 

Thanks for answering mate

You can use the Lua Script function "getDrawArgumentValue" to check a model argument.

local varUnit = Unit.getByName("theCH-47s unitname here")

   if varUnit:getDrawArgumentValue(86) > 0.5 then

trigger.action.setUserFlag("DOOR", 1)

end

Now you can use the Flag "DOOR" to trigger things as usual e.g. send messages etc.

Reset the Flag by setting it to 0.

Not tested, but should work.

Thank you Shagrat

I am however a simple man with no knowledge about scripting or how to use it. And to be honest, I don't feel like spending a whole bunch of time diving into that rabbit hole. I was hoping to do this with the simple ME tools.

But it's ok, I'll find some workaround

You can simply put the code into a switched condition "do script" trigger and use the Flag is true "DOOR" to do stuff like Message to coalition/group etc.

Just reset the flag with a "set flag false" in the trigger, if you need to track multiple uses of the ramp.

You only need to add the UNITNAME to the script in the get.unitByName("unitname") part.

The moment the ramp is lowered more than half it should trigger the "DOOR" Flag as true.

Thanks @shagrat, that sounds simple indeed. I'll give it a go

Hi @shagrat,

 

For sure I must be doing something wrong, I just don't know what.

 

I created the switched condition for the script and a triggered "Door open" message when flag DOOR is true. But it doesn't seem to work.

(couldn't find the "set flag false" action, so I used "flag off" instead)

 

Any ideas?

For whatever reason DCS does not like "Switched Condition" with "Do Script".
I changed the Script trigger to "Contineous" and added an else condition to the script.

local varUnit = Unit.getByName("CH47player")
if varUnit:getDrawArgumentValue(86) >0.5  then
      trigger.action.setUserFlag("DOOR",1)
else
       trigger.action.setUserFlag("DOOR",0)
 end 

Then two separate "switched condition" for the appropriate Flag "DOOR" is 1 (ramp lowered) and  Flag "DOOR" is 0 (ramp raised)...

But easier to see for yourself. I attach the MIZ file so you can see what exactly I did there.

Thanks mate!

I'll give it a go as soon as life allows me to 

[sirrah]

Yes, this works!

Now that I successfully used a script in one of my missions, I can now rightfully say:

[sirrah]

I cheered a bit too soon I think @shagrat, because when testing I came across the following issue

 

When the player crashes, it results in this prompt:

 

Do you have any idea on how to solve this?

I attached my mission. The script triggers are at the top of my trigger list.

Chinook training mission - in progress.miz

[shagrat]

Yeah, needed to do a sanity check on the varUnit, as a continous trigger will check the condition every second and if the unit crashes it won't find said unit...

local varUnit = Unit.getByName("00_Player")
if varUnit ~= nil then
if varUnit:getDrawArgumentValue(86) >0.5  then
      trigger.action.setUserFlag("DOOR_00",1)
else
       trigger.action.setUserFlag("DOOR_00",0)
end
end

I also did adjust for the fact, you have more than one player. So The script can be executed for individual units Flag ("DOOR_00" and "DOOR_01").
Additonally I eliminated the need to use a second Flag so I added a FLAG "DOOR_00" EQUAL 1 to the conditions using the same flag that is set in the script, and I added a message from a virtual "crew chief" to let the pilot know if the ramp is lowered or raised.

Have a look at all the orange triggers in the Script Editor to see what has changed:

Wizardry to me, but it works!

Thanks a bunch mate
