Scripting

[deathsangel]

Hey guys, I have 3 quick questions about scripting.

1) why would you use scripting(lua, perl, ruby, etc...) instead of pure c++ inside of your game.

2) which scripting language should I chose, is there a difference in them?

3) how do you implement a scripting language

1) why would you use scripting(lua, perl, ruby, etc...) instead of pure c++ inside of your game.

One reason is to separate game logic from the engine.
Another is that scripting languages tend to be more expressive, meaning you can implement a concept in less code. They make development faster. So for anything that doesn't need to be especially optimized for performance, scripting languages make development more efficient.

2) which scripting language should I chose, is there a difference in them?

There are differences between them, and I don't know which one you should choose. Lua is typically used for games, because it is designed to be embedded in other programs. Another choice for a language that's designed to be embedded is JavaScript.

3) how do you implement a scripting language

It's different for each language. Basically, there's a library for the language interpreter, and there are methods that allow you to bind functions/objects in the scripting languages to functions/objects in the host application (the game).

So your saying I should chose lua?

So your saying I should chose lua?

yes, thats what he's saying.
personally ( everybody ) i like lua and python you should probably use lua its nice and easy

Nobody is saying you should use Lua. You should first decide what you want to use a scripting language for (and based on the fact that you're asking "why," I don't think that you really have a reason to use a scripting language).

There is a specific time and place for that kind of extensibility. If it isn't necessary, you're going to spend more time integrating the scripting language than if you had tackled the problem with just C or C++.

1) Identify the problem 2) Go research scripting languages. There is no "best" language. Some are better than others in particular scenarios. Perl is amazing at text-based manipulation, but it's slow as shit. Python is a great multipurpose language, but it's overkill for simple tasks. Ruby is getting really popular these days, and it's pretty much the object oriented scripting language of choice, but it's also slow and expensive as hell. Lua is fast and lightweight, but feature-wise it's a pussy compared to lots of other languages.

True. At least until you pimp it out with access to the engine/app.

Does it change back when he makes one more post?

[MarauderIIC]

Yes. Back to talking about scripting, everybody! On task!

Marauder, you are the man.

Lusikka got it didn't she???
Then back to scripting

I think Lusikka has/had a special rank, so it didn't show. I might have done it after she passed it, too.
