obter .AMX em hexadecimal - RazorGuigo - 28.02.2018

para fazer isto o binario tem de ser divisivel por 4!

estou seguindo um exemplo do ******, que possibilita que um script "injete" um FS, e carrege pelo prуprio GM, mas para sua escrita nгo pode ser em string porque o encode pode denegrir o caracteres de algumas celulas.

este й um exemplo que ****** fez e ficou correto
https://github.com/Open-GTO/sa-mp-fixes/issues/80

PHP код:



//codigo source:

forward OnRconCommand(const cmd[]);

public OnRconCommand(const cmd[]) return 0;

//hexadecimal:

static BIN[] = {0x00000057, 0x0808F1E0, 0x00080014, 0x00000050, 0x00000064, 0x00000064, 0x00004064, 0xFFFFFFFF, 0x00000038, 0x00000040, 0x00000040, 0x00000040, 0x00000040, 0x00000040, 0x00000008, 0x00000042, 0x6E4F001F, 0x6E6F6352, 0x6D6D6F43, 0x00646E61, 0x2E007880, 0x00305980};

//string resultado do hexadecimal:

[   ас  P   l   l   l@  яяяя8   @   @   @   @   @      B    OnRconCommand Ђx .Ѓ    Ѓ    ЂY0Ѓ   пс                    RCMD.pwn                         cmd                         OnRconCommand   _  bool        

//string esperado:

[   ас  P   l   l   l@  яяяя8   @   @   @   @   @      B    OnRconCommand Ђx .Ѓ    Ѓ    ЂY0Ѓ   пс                    RCMD.pwn                         cmd                         OnRconCommand   _  bool

como podem ver, o resultado ficou exatamente igual e sem falhas.

mas pela todas as formas que tentei a string gerada pelo codigo hexadecimal fica diferente, do compilador:

Код:

//codigo fonte:
native CallRemoteFunction(const function[], const format[], {Float,_}:...);
forward OnRconCommand(const cmd[]);

public OnRconCommand(const cmd[])
	return CallRemoteFunction("I_RCMD", "s", cmd);

//resultado esperado:

ficou bem proximo do original, porem ainda tem 1 espaзo em cada celular -. e nгo achei o valor repetido muitas vezes:

Re: obter .AMX em hexadecimal - ThePhenix - 01.03.2018

Note that this won't work if the size of the .amx file is not divisible by 4. Sorry for speaking english in this section.

How can I have this control?

If you were reading and writing to the file byte by byte then this wouldn't be a problem. However, what you can do is write the number of bytes from the .amx file that are divisible by 4 and treat the remainder bytes in a different way.

For instance, if a file has a size of 131 bytes, you could write or read the first 128 bytes (divisible by 4) and you have a remainder of 3 bytes that you can read or write separately. Note that we're using little endian order.
