New page

Starting with [[Unreal Engine 2]] [[UnrealScript]] supports '''cpptext'''(prefix for [[wp:C++]]<sup>text</sup>) block declarations. The '''cpptext''' is a block declaration where programmers can implement C++ functions it also can only be declared in native classes, any text within this block will then be exported to the corresponding native [[classes|class]] <code>''prefix''Classes.h</code> file when compiled.

Starting with [[Unreal Engine 3]] [[struct|structs]] can also have a '''cpptext''' block but named as '''structcpptext''' instead.

==Example==
Taken from <code>Canvas.uc</code>.
<uscript>
cpptext
{
//...
void DrawTile(UTexture* Tex, FLOAT X, FLOAT Y, FLOAT XL, FLOAT YL, FLOAT U, FLOAT V, FLOAT UL, FLOAT VL, const FLinearColor& Color);
//...
}
</uscript>
This exports <code>DrawTile</code> into class <code>UCanvas</code> in file <code>EngineClasses.h</code> e.g.
<uscript>
class UCanvas : public UObject
{
//...
void DrawTile(UTexture* Tex, FLOAT X, FLOAT Y, FLOAT XL, FLOAT YL, FLOAT U, FLOAT V, FLOAT UL, FLOAT VL, const FLinearColor& Color);
//...
};
</uscript>

==Why use cpptext over native functions==
Even though you can just make a native [[UnrealScript]] function that will also get exported the same way but then translated to C++, it doesn't support all formats thus in that case the native coder can implement functions that cannot be declared in UnrealScript but also because the native coder might not want you to be able to call a function from within UnrealScript.
