Ok, here's the deal. I finally found the no collision address for Spyro 2 but only want to activate it when Spyro is gliding.

Spyro gliding is 16
Spyro No Collision is 1

Whenever this address ePSXe.exe+AEC060 =16
I want this address ePSXe.exe+AEC115 to become 1

What would be the easiest and simplest way to do this ?

It'd be really useful for me to have an example of this.

You're a lifesaver. Took me years to find this particular code. I'm very persistent at finding stuff haha. However.., I'm not so good at scripting.
I had to tweak it to make it work but after many trials and errors with the script you posted I now got it to work.Thank you!

Hey, is there a way to specify two values in one adress instead of writing an entire new line?

Code:

newmem:
push eax
mov eax,dword ptr [ePSXe+AEC115]
cmp dword ptr [ePSXe+AEC060],10 <---- (10&11&#255 for example)

Instead of
newmem:
push eax
mov eax,dword ptr [ePSXe+AEC115]
cmp dword ptr [ePSXe+AEC060],10
cmp dword ptr [ePSXe+AEC060],11
cmp dword ptr [ePSXe+AEC060],255

or cmp dword ptr [ePSXe+AEC060],activate on anything between 10&255 or higher than 10.

I think I'm making things way harder than they should be, there should be a simple way to do this.

If I understand correctly you want to compare the DWORD at [ePSXe+AEC060]?

[Unicorngoulash]

newmem:

push eax
mov eax,dword ptr [ePSXe+AEC115]

I'd like to have these 3 lines be 1 single line
cmp dword ptr [ePSXe+AEC060],1
cmp dword ptr [ePSXe+AEC060],2
cmp dword ptr [ePSXe+AEC060],3

cmovz eax,[newvalue for ePSXe+AEC115]
mov dword ptr [ePSXe+AEC115],eax
pop eax
jmp return

newvalue for ePSXe+AEC115:
dd #10

return:

[ePSXe+AEC060] controls what happens to [ePSXe+AEC115]

So if [ePSXe+AEC060]=,1,2,3 it should change [ePSXe+AEC115] to 10.
But instead of writing and copying 3 lines to do that I think I'm missing a simple symbol to make it easy.

I'm now doing this which does work but doesn't seem practical.:
cmp dword ptr [ePSXe+AEC060],1
cmp dword ptr [ePSXe+AEC060],2
cmp dword ptr [ePSXe+AEC060],3

Instead I'd like to see something like if cmp dword ptr [ePSXe+AEC060] is 1 or 2 or 3 turn [ePSXe+AEC115] to 10

Using cmp consecutively erases the flags from the previous cmp, so probably some bugs in your code there.

If all you want is for the code to activate when 10<=[ePSXe+AEC060]<=255, that is what the code posted above does. Fill in the activation part yourself.

That can't be encoded in a single instruction, and as predprey said, you need to test the flags immediately after each comparison.

However, if the values are contiguous (i.e. 1-3), you could do something like this:

do what the users mentioned, in other words ... use more conditions.
