On-Screen Killstreak Counter

[FutureRave]

Hello, I'm new to the Pluto plugin/script development but I have some previous experience in Java (OOP alike).
I friend of mine gave the script in c# for Tekno which displays the killstreak counter on screen. I wish to port this to Pluto MW3
First of all, it would be great if some could clarify the pro and cons of using chaiscript rather than c++ plugins. What is the main difference (plugins more capable than scripts?).
Which of those has the capability of doing some like this? Keep in mind that the counter should remain at a fixed position (let's say top screen).
Has someone already made a similar thing?
I really need someone to point me in the right direction before I start coding.
Thanks

Edit 1:
Okay, I've read carefully other posts on this forum and this is where I am right now:

This is supposed to be the project setup.
Now let's say I want to do the hello world message like in the tutorial.

level.onNotify("connected", fun(arguments) {
	var player = arguments[0];
	
	player.onNotify("spawned_player", fun[player](arguments) {
		helloWorld(player);
	});
});

def helloWorld(player)
{
	player.iPrintlnBold("^1Hello, world!");
}

where do I chuck this code? Do I need extra headers to code for Pluto?
Thanks

There are currently two ways of modding Pluto. One is using unmanaged C++ code - that's what you have in Visual Studio. The other, and more limited, is using managed ChaiScript code - that's the one you have in the tutorial post.

To load the code from the tutorial, simply save it as a .chai file in %localappdata%\Plutonium\storage\iw5\scripts folder.

I think this is enough to start
In C ++, it will be very difficult to create such without knowledge

// This is ChaiScript
level.onNotify("connected", fun(arguments) {
        // you can make new var
        // var player = arguments[0];
	var hud_text = gsc.newClientHudElem(arguments[0]);
	hud_text.set("x", 0);
	hud_text.set("y", 0);
	hud_text.set("font", "hudbig");
	hud_text.set("fontscale", 0.65);
	hud_text.setText("^2HELLO WORLD, THIS IS HUD!");
});

There are a few problems:

1. Do not spam SET/GET
2. To update the numbers, it is better to use SetValue, not SetText (yes you have to tinker with the position, but otherwise your server may crash)
3. Better to use Plutoscript Framework to handle event kill player

Diavolo Did you get the kill streak counter script done?

Kalitos No, I gave up 8 months ago because Chai script lacks everything I am used to when I code in other programming languages.
Recently the clan I'm a part of opened a server on Pluto so I might do something although given the fact IW4M already has a built-in killstreak counter I don't think I will do this specifically.
Also, Pluto doesn't have all the Hud Elements in handy so it's a nightmare to centre text on-screen since different players might have different resolutions.
