How do I add a kit selector for each class?

[The_Turkish_Moose]

I've looked around for tutorials which cover this feature but have found NOTHING. I would like to know how to add a kit selector button like the ones shown in the two videos bellow.




If someone could point me in the right direction, I will be very greatful

easiest way is to get those mods and look how they did it. Most likely something in the menu files. you can also check how pr does it, also in to menu files.

Downloaded Armoured kill - the mod did not have the feature in the Armoured kill video
Tried downloading Real War 3.0 but could not download the right mod anywhere

I guess I'll have to give the PR files a look. Hopefully, I can make sense of it! If anyone else has any knowledge on the matter, please post! Thanks Mats!

sorry not to help, but where do I download this Real War 3.0 mod?

only found 2.0

Both AK and RW using default "Unlock" system, while PR one is a bit more complicated.

That's how i understand it:
1. HUD being initialized by content\menu_server.zip\hud\hudsetup\hudsetupmain.con
2. Specifically we're interested in Customization/HudSetupCustomization.con
3. In that file we're creating our global kit node by:

Code: Select all

hudBuilder.createSplitNode		Global KitCustomInitRoot

4. Then we're initializing all the kits in python(that would be used later) by sending some rcon command.
Look for that file and what it does.

Code: Select all

run kits/ru/ru_init.con

5. Then we're creating kit info nodeS(all of them) with alt\std button

Code: Select all

hudBuilder.createSplitNode		Kit2CustomKit arf_Kit2Info
hudBuilder.setNodeShowVariable	DemoRecInterfaceShow
run kits/ru/ru_2.con

6.That's our ru_2.con file, medic(kits numering from 0)
Node create:

Code: Select all

rem --- kits ru_2.con ---
rem --- Generated by PRBuild ---

hudBuilder.createSplitNode			ru_Kit2Info ru_Kit2
hudBuilder.setNodeShowVariable		Kit2Show

Creating picture node with std weapon image(ParentNode, NodeName, position X, position Y, size X, size Y)

Code: Select all

rem --- Weapon Images ---
hudBuilder.createPictureNode		ru_Kit2 ru_Kit2_StdImg 21 227 148 40
hudBuilder.setPictureNodeTexture	Ingame/Weapons/Icons/Hud/rurif_ak74mscope.tga

Creating picture node with alt weapon image(ParentNode, NodeName, position X, position Y, size X, size Y)
Notice it's not shown not because it's under std image, but because it's out of screen!

Code: Select all

hudBuilder.createPictureNode		ru_Kit2 ru_Kit2_AltImg -1000 -1000 148 40
hudBuilder.setPictureNodeTexture	Ingame/Weapons/Icons/Hud/rurif_ak74m.tga

Creating STD button. Take note that it has default unclicked state, so it's out of screen by setting it's coords -1000 -1000.
1 texture is for default state.
2 for hovering with mouse.
3 assuming it's for clicked state.

Code: Select all

rem --- Buttons and Labels ---
rem --- Std Kits ---
hudBuilder.createButtonNode			ru_Kit2 ru_Kit2_StdButton -1000 -1000 40 18
hudBuilder.setButtonNodeTexture		1 Ingame/Respawn/button_shortLight.tga
hudBuilder.setButtonNodeTexture		2 Ingame/Respawn/button_shortLight.tga
hudBuilder.setButtonNodeTexture		3 Ingame/Respawn/button_shortLight2.tga

Click sound.

Code: Select all

hudBuilder.setButtonNodeConCmd		"sound.playSound rosePress" 0

Sending rcon command into bf2 if pressed. Bf2 catches it and looking if there's registered handlers for remote command. If any command found, it's being catch by PR modules, and(i assuming) being stored by some internal variable.

Code: Select all

hudBuilder.setButtonNodeConCmd		"rcon custom 2 0" 0

Assuming it's a command to remember choice done by player.

Code: Select all

hudBuilder.setButtonNodeConCmd		"rcon select 2" 0

Setting kit for player by internal bf2 method.

Code: Select all

hudBuilder.setButtonNodeConCmd		"spawnManager.setPlayerKit 2" 0

Running script for HUD changes. Notice the argument std. Also 0 state - react only if pressed, 1 - if hover, idk if there's more states.

Code: Select all

hudBuilder.setButtonNodeConCmd		"run menu/HUD/HudSetup/Customization/scripts/ru/ru_2.con std" 0

Text for pressed button(-1000, -1000), nothing here.

Code: Select all

hudBuilder.createTextNode			ru_Kit2 ru_Kit2_StdLabel -1000 -1000 40 18
hudBuilder.setTextNodeStyle			Fonts/hudFontLocalBold_9.dif 0
hudBuilder.setNodeColor				0.729 0.729 0.729 1
hudBuilder.setTextNodeString		"HUD_TEXT_MENU_SPAWN_KIT_STD"

Button textures and text for non-pressed button.(it's present on screen and awaiting for click)

Code: Select all

hudBuilder.createButtonNode			ru_Kit2 ru_Kit2_StdButtonP 167 230 40 18
hudBuilder.setButtonNodeTexture		1 Ingame/Respawn/button_shortLight2.tga

hudBuilder.setTextNodeStyle			Fonts/hudFontLocalBold_9.dif 0
hudBuilder.setNodeColor				1 1 1 1
hudBuilder.setTextNodeString		"HUD_TEXT_MENU_SPAWN_KIT_STD"

And here's alt button - it's on screen, awaiting for being pressed.

Code: Select all

rem --- Alt Kits ---
hudBuilder.createButtonNode			ru_Kit2 ru_Kit2_AltButton 214 230 40 18

hudBuilder.setButtonNodeConCmd		"sound.playSound rosePress" 0
hudBuilder.setButtonNodeConCmd		"rcon custom 2 1" 0
hudBuilder.setButtonNodeConCmd		"rcon select 2" 0
hudBuilder.setButtonNodeConCmd		"spawnManager.setPlayerKit 2" 0

hudBuilder.setNodeColor				1 1 1 1
hudBuilder.setTextNodeString		"HUD_TEXT_MENU_SPAWN_KIT_ALT"

7. In file above, when we're pressed alt\std button, we're not only sent event to python, but runned some script, placed in:
menu/HUD/HudSetup/Customization/scripts/ru/ru_2.con
The code below is needed for initialization, we're moving all th components outside the screen.

Code: Select all

rem --- scripts ru_2.con ---
rem --- Generated by PRBuild ---

hudBuilder.setActiveObject		ru_Kit2 ru_Kit2_StdImg
hudBuilder.setNodePos			-1000 -1000
hudBuilder.setActiveObject		ru_Kit2 ru_Kit2_StdButton

The code below is reading argument sent to our script, and moving nodes for kit init to required positions.

Code: Select all

If v_arg1 == std
	hudBuilder.setActiveObject		ru_Kit2 ru_Kit2_StdImg
	hudBuilder.setNodePos			21 227

	hudBuilder.setActiveObject		ru_Kit2 ru_Kit2_AltButton
	hudBuilder.setNodePos			214 230
	hudBuilder.setActiveObject		ru_Kit2 ru_Kit2_AltLabel

	hudBuilder.setNodePos			214 230
endIf

8. During map init we're calling PR inits by running faction_init.con file in content\factions_server.zip, and resetting all the hud nodes by running hudcustomizationreset.con by running all the scripts from it(remember, scripts moving nodes outside screen first, and checking for args later)
9. Then, as faction_init.con being called 2 times with 2 args(number of team, v_arg1 and name of team, v_arg2), we're running menu/HUD/HudSetup/Customization/HudCustomization.con v_arg1 v_arg2 2 times.
10. As .con grammar quite strict and not even have loops, PR'devs had to implement such check.
The code below checking if v_arg1 == number of our team, and if yes - checking for it's name in if-elseif loop
If team found, it's setting activating hud node, and setting visibility to team by setting it's node variable.

Code: Select all

That's our painful HUD part, and it's done for now.
11. As bf2 has some major flaws in it's design, we're able to fix em with some python magic code
One of the problems is that there's can't be more than 7 kits initialized via map's init.con.

But with python, we're able to change kit's right-in-spawn in-game. How do we decide which kit to use?
In #6 point we're sent some command like that:

Code: Select all

rcon custom 2 0

And as we saw, 0 or 1 were decided as argument because of alt\std button pressed state.

So basically, when we have kit selected\changed, python cathching this events, and storing those variables.
When player spawning, python checking which kit has been selected, which arg given(0, 1, assuming it's alt\std),
and changing player kit just-in-spawn moment.

Ofc, i could've mistaken in some parts, as PR sources are closed, but i assuming that's how it works in PR

sorry not to help, but where do I download this Real War 3.0 mod?

only found 2.0

I couldn't find the download for it either!

rPoXoTauJIo, thanks for that awesome post. I'll look into it soon and let you know how it goes! THANKS AGAIN

Cause their official site&ftp are down.

All credits to BD i assume. I'm still not quite understand some parts of HUD managing, as after initializing mod&map there's quite a lot of cross-file runs and node changes.
Just keep in mind that part of this magic are closed behind PR sources, pretty much everything above is HUD madness, resulting in sent rcon command into py.

Here is good example how to modify player kit onspawn:
