Unreal Engine 3: Code

The UDK uses Kismet and UnrealScript.
Only the professional version of Unreal Engine (not the free UDK) allows you to use C++, AFAIK.

If you're new, then you shouldn't use C++ anyway -- it's an advanced, low-level, systems programmer's language, not a beginners game programming language.

Then in your opinion are there any limitations in unrealscript versus cpp?

Unrealscript can only be used with Unreal Engine / UDK and "only" lets you control the unreal engine.

C++ can be used for anything(almost) but supports almost nothing. it is great for building new systems but not really a nice language to use for controlling existing systems. (Which is why so many games these days use higher level scripting languages(unrealscript, lua, python, etc) for the game logic)

UnrealScript is meant for use with unreal engine only and is a highly abstracted scripting language that allows you to focus on writing gameplay without dealing with advanced programming concepts. Performance wise, its much slower than C++, as it uses a middle-ware interpreter to execute. However, for "almost" all gameplay programming needs in UDK, it should suffice. Infact, even Epic suggests to code gameplay with UnrealScript and not C++, unless you are working on really performance driven engine code.

Hope this helps.

Most people don't know this but you can use C++ libraries with UDK by using the "DLLBind" feature:

In fact one clever guy figured out how to trick DLLBind into calling into C# libraries yet this is not officially supported.

Partially true, yes UnrealScript runs 20X slower than C++[1] and it is highly abstracted. But you can do a lot more than basic gameplay scripting with it. The networking component of the engine is very complex and you can even use it to implement web servers. Also a lot of the classes you deal with in UnrealScript are extended directly from C++ classes so most of the "performance critical" code that you would use (vector ops, math functions) have UnrealScript functions , so you wont be needing to really go into C++ at all.

EDIT sorry for my poor grammar, I was drunk.

UDK is not free? Hence why not use OGRE etc.? Maybe have a look at gamekit?

I know c++ and Blender, so I'll go with Ogre unless someone has good arguments against.

UDK is free and if you want to go commercial it is ~15 times cheaper than unity (99 USD for license with UDK opposed to 1500 for Unity Pro). UDK is VERY free and everything shipped with it is 100% AAA and tested time and time again to be the best out there. You don't win best engine of the year several times in a row for no reason.

Also it is very interesting to see so little knowledge of UDK on this site.. maybe I should do some posts about it (or maybe I'm just in the wrong forum)?

Wait for UDK 4 for and we will only have kismet and C++ code they have gotten rid of UnrealScript , also dynamic C++ compiling on the fly. See last 2 minutes of video.

Yes looks good, but unless I could export to Linux, I won't even bother to look at that.

That is so weird...
