Quick Modding/Hacking Answers Thread

There's only 64 skipflags, anything above that will start poking unrelated memory.

@Bi_N just so it's explicitly clear for everyone, this means the valid range of skipflags is <SK+0000 to <SK+0063. Skipflag 0064 is not valid. Anything higher will not function as skipflags and instead, iirc, it will function like a regular flag as it's bleeding into the next section of memory. To avoid problems just only use 0 to 0063 for skipflag usage and use regular <FL+ for regular flag usage.

Meanwhile the valid range of normal event flags are <FL+0000 to <FL+7999 (8000 flags), but don't actually use flag 0000 because you'll run into other problems (So really it's 1 to 7999 that's safe for those).

And write down the flags that you use somewhere! Like have a .txt document in your mod folder (what I used to do) or write them down at the top of the script for map 0 (what I currently do).

 

Alrighty, what does LEA do? Specifically in the situation below:


It's in the MakeSoundObject8 function at address 0041A8F0 if that helps.

It's in the MakeSoundObject8 function at address 0041A8F0 if that helps.

It calculates the math expression inside [the brackets] and then puts that value in the register (in this case ECX). NOT what's at that memory address, but the value itself.

So like, imagine that the value of edx is 4.
The instruction:
mov ecx, dword[edx+10]
would calculate edx+10 (in this case 4+10 = 14), then get whatever is inside memory address 14 and put that into ecx. If memory address 14 points to the value 0C, then 0C goes into ecx.
Meanwhile, the instruction
lea ecx, dword[edx+10]
also calculates edx+10 (which is 4+10 = 14), but then just puts the 14 into ecx. Doesn't look up the memory.

In the example you have, it puts whatever edx + (eax*8) + 4A4B48 is directly into ecx, no looking at memory.

If you're using ollydbg, you can right click an instruction and select "Help on command".

 

Does anyone know what to use to create a CS2 mod? I speak Spanish and English xdd

Spoiler

 

Maybe you have to ask it to someone that make CSE2 mods

Tal vez tengas que preguntarle a alguien que haga mods para CSE2

You just gotta go download it from github: CSE2
Though the branches are for different things, e. g. Portable is for porting Cave Story. You're probably going to want to use the enhanced-lite because it's intended for modding.
