So I've been messing around with a bit of ASM and everything has been fine. For example:
int *lives = (int*)(0x0208B364); //Lives int *player = (int*)(0x02085A50); //Player number void hook_02020354() //getCoin function { if(*player == 0) { *lives = 99; } } So if Player 0 (Mario) gets a coin, his lives are turned to 99. However, I'd like to define my own condition. For example, such as if Mario was to jump, touch a fireflower, or even if the player pressed a certain button on the DS, THEN his lives would turn to 99. I've looked around the board but can't seem to find out how to do this. I've even downloaded other .cpp files but just can't figure out how they are working. Sorry if this question has been asked already but I'd love to know! Thanks. |

Simply replace
void hook_02020354() with a function in the game that checks for what certain condition you want. I however do not know anything about the game's functions nor know how to create custom ones in case the condition check you want does not exist (well actually i might, because i've programmed in C# before and C++ is pretty similar, but i haven't fiddled around with anything yet.)

You can use the IDA database in combination with no$gba debugger's breakpoint feature to locate functions you are looking for.
For things like detecting jumping, you could run a check everytime the player actor updates: void hook_addressOfMarioActorUpdate(mA* MarioActor)
{
if (!mA->isOnGround)
{
// Whatever
}
} Btw that layout is eye-hurting Also C# simmilar to C++? ugh, I wouldn't say so. Especially the most important thing in NSMB hacking: pointers. _________________________ GitHub - Kuribo64 - YouTube |

Ahhh alright. What about stuff like the pressing of a button? How would I go about doing that?

Yep, that worked. Completely forgot about nsmb.h. Thanks!

I think you can use worded functions, as long as they are listed in arenaoffsets. Otherwise, as mariomaster said, you'll have to use the nocash debugger to find the offsets yourself.
