DCS Mods structure : How to create your plugin from scratch

aaron886 · January 26, 2013

I bet he did, he even posted some of his work in this topic;)

I'm expecting a better first effort than that, unfortunately. There are great resources out there.

RagnarDa · February 11, 2013

Sorry if this has been posted about before, but have anyone figured out a way to get weight on wheels? getWOW_LeftMainLandingGear(), getWOW_NoseLandingGear() and getWOW_RightMainLandingGear() always returns 0 for me.

Also, has anyone figured how you are supposed to send data between the dll-flightmodel and the lua-devices? I am working on a solution using windows named pipes, but it seems like a unnecessary hack.

BUMP!

isnt this a limitation/incomplete part of 1.2.2.?

(the AFM interaction Code for 3rd party External FMs)

Without access to more ED tools, the only method I know is a workaround.

You would essentially be using unused external arguments, but I suggest numbers above 500 so as not to interfere with other external argument purposes. Also, I have recently found that using numbers over 602 crashes the game.

RagnarDa · February 13, 2013

Thanks! Will look into your method, but in the meantime I am almost finished with my workaround.

Funny how that with so many module-developers, no-one seems to know how to tell (reliably) if the aircraft is on the ground. Maybe that's one of the things keeping Beczl from releasing his jet?

RagnarDa · February 13, 2013

Anyone managed to get the F-15C, A-10C or Ka-50 cockpit working for your mod? I thought it would be a good way to learn the cockpit system as it has working gauges, switches...

Mt5_Roie · February 13, 2013

I've been using the A-10c cockpit with our mod so I can learn how to program switches and gauges. Waiting on our graphic guy to finish our cockpit so it was a good way to learn.

RagnarDa · February 14, 2013

I copied the files in Flaming Cliffs/Cockpit/Resources to the same folder in my plane and added these lines in entry.lua:

mount_vfs_texture_path  (current_mod_path ..  "/Cockpit/Resources/Model/Textures/F-15C-CPT-TEXTURES")
mount_vfs_model_path    (current_mod_path ..  "/Cockpit/Resources/Model/Shape")
mount_vfs_liveries_path (current_mod_path ..  "/Liveries")

I also changed this line:

make_flyable('MyPlane','Cockpit_F-15C',FM,nil)

But there are no cockpit displaying. What did I miss?

SkateZilla · February 14, 2013

no idea, I know when I delete our cockpit folder,

The game now defaults to the SU-27 Pit, when it used to default to the SU-25.

joey45 · February 14, 2013

It defaulted to the 17 pit for me originally.....

Silver_Dragon · February 14, 2013

Ok, I start to "code" the Pr_183.... I follow the first post in the first page:

I only mod a little entry and plugin files:

entry

declare_plugin("Pr_183 by Silver_Dragon",

{

installed 	 = true, -- if false that will be place holder , or advertising

dirName	  	 = current_mod_path,

version		 = "1.2.2 Beta",

state		 = "installed",

info		 = _("The Proyect 183 was a soviet Torpedo Boat used by the URRS and allieds"),



Skins	=

{

	{

		name	= "Pr_183",

		dir		= "Theme"

	},

},


Missions =

{

	{

		name		= _("Pr_183"),

		dir			= "Missions",

		CLSID		= "{CLSID5456456346CLSID}",

},

},


LogBook =

{

	{

		name		= _("Pr_183"),

		type		= "Pr_183",

	},

},


InputProfiles =

{

	["Pr_183"]     = current_mod_path .. '/Input',

},

})

---------------------------------------------------------------------------------------

dofile(current_mod_path..'/Pr_183')


---------------------------
---------------------------------------------------------------------------------------
plugin_done()-- finish declaration , clear temporal data

I change add_arcraft by this on the addon declaration.

},
}

add_surface_unit(Pr_183)

and work, show plugin installed into DCS:W, but the problem show when I put 'make_flyable' on entry file.....

make_flyable('Pr_183',current_mod_path..'/Cockpit/Scripts')

I have´t a cockpit modeled. The log show them:

UNKNOWN main: GUI Error: [string "./mods/tech/Pr_183/entry.lua"]:80: attempt to call global 'make_flyable' (a nil value)

i am confused

is it an aircraft now ?

or a ground vehicle ?:dunno:

Does it matter?

Silver_Dragon · February 15, 2013

negative, a ship........ is "flyable" has aplicable to aircrafts, helos, vehicles and ship, that can be work. If "flyable" has only helos and aircraft, the intent has in vain.

NineLine · February 15, 2013

So does anyone have a good/successful example of file structure and entry.lua file for adding a ground unit? If its in this thread I am missing it :huh:

SkateZilla · February 15, 2013

i dont have combined arms so i have no way of study those scripts.

Haddock · February 24, 2013

So new YES/NO question:D

Does somebody succeeded in adding a ground or naval unit with its own "cockpit"? aaron886?

aaron886 · February 24, 2013

Not with a cockpit, no. I don't own combined arms.

Haddock · February 24, 2013

Neither do I:smilewink:

Thanks for the answer:smartass:

RagnarDa · February 24, 2013

I have combined arms and I could try it if someone tell me how I should do.

jib · March 3, 2013

I have added:

DHSK ground unit model with the mods folder.

But I deleted my DCS World folder without backing it up so will have to learn how to do it again. :mad:

You probably want to search This part of the forum not in this thread

This Thread helped me when I was stuck on adding ground units.

and someone posted a tank mod example but I can't find it anymore and the Wunderluft Sample is the best start for any new modeler.

It is a real shame there arn't any good tutorials on making new stuff for DCS.

Edit I found my file:

Now this doesn't give a working ground vehicle but it is a step in the right direction, i think it doesnt work because of "set_recursive_metatable(GT, GT_t.generic_stationary)" but I don't know what else there is possible to put in there.

and if i comment back in "make_flyable('DSHK')" DCS doesn't load at all.

I have attached the zip put it in /mods/tech

You will need to copy over your own Combined arms dll.s from your install.

I am excited because I have managed (by some fluke) to make my DHSK "drivable" with combined arms.

it is no where near finished and fires at a right angle to the barrel, but it is a great step in the right direction for me.

I have posted the .lua's the .edm and the .max in a zip Edit Uploaded Newer VersionHere.

Just copy it to you Mods\tech folder and it will show up as DHSK under armor in the mission editor.

I have no time to work on it tonight but will try and polish it up tomorrow.
