Lineage2 Interlude Draw text to canvas (c++)

[wongerlt]

Hello,
Maybe someone try to find parameters for this function? from Engine.dll
?DrawTextToCanvas@UCanvas@@UAEKHHKPBGKKKMHW4L2Font Type@@HHKHHHPAV?$TArray@PAVFL2ColorFontInfo@@@@GW4 EFontExceptionType@@H@Z


public: virtual unsigned long __thiscall UCanvas::DrawTextToCanvas(int,int,unsigned long,unsigned short const *,unsigned long,unsigned long,unsigned long,float,int,enum L2FontType,int,int,unsigned long,int,int,int,class TArray<class FL2ColorFontInfo *> *,unsigned short,enum EFontExceptionType,int)


What each parameter mean, maybe someone was facing with it? : confused:

most interesting for me is enum L2FontType, class TArray<class FL2ColorFontInfo *> *, enum EFontExceptionType

all other parameters i think possible to guess.

Thanks for any information.

Перехватывай эту функцию и смотри, что в нее передается.
Либо используй перехват функций DirectX (Direct3DCreate9), в интернете есть примеры, как с помощью DirectX рисовать что-либо в окне La2

L2 Create new dx device when window resize? because when i resize window me draws stop working. how to fix it?не знаю, не работал с dx, но повторное создание контекста должно отловиться с помощью перехваченной функции Direct3DCreate9.
