hey everybody, having a little trouble with this script, wonder if i could get some help

in Alan Wakes American Nightmare, i have a script that gives me infinite clip, which is awesome, but i also want infinite ammo as well, i find the value no problem, but when i go to modify the opcode it looks like this

mov [esi+eax*4+20],ecx
mov ecx,esi

i've tried adding "nop"s, i've tried adding my own math before and after, and no matter what, as soon as i shoot with the script active, it crashes, now if i go into the memory viewer and click "replace with code that does nothing" then it works just fine, but i want to put this into script form, any help would be appreciative, thanks!!

If it worked when you nop'ed it in the dissassembler it should work in a script. usually if you nop an instruction and there is a crash it means it is a shared opcode, but since it worked it might just be your script.
can you edit in of one of the scripts you used so i can see it?

probably wrong number of nops, make sure you have the correct number to match the original byte count.

this is the script I wrote, I think I have the right number of nops, when I go into the memory viewer, I hit "replace with code that does nothing" and count the number of nops it uses and use that many, unless I did something wrong in the script, but I've wrote other scripts just like this before and they worked fine?

Let CE build your script for you. Comment out the mov [esi+eax*4+20],ecx but leave the mov ecx,esi.

your not pestering.
it doesn't matter if it is like eax or [eax]. but yes, it will be writing/accessing something else. most of the time though you don't want to simply nop/modify opcodes like mov,edx,[eax] where the destination is not in brackets, regardless if it writes your address or not. It changes from game to game though.
Cant think of any tutorials off the top of my head, I know there are alot of posts with discussions of stuff like this though. download some tables and have a look at how different people make scripts and try and try and follow and understand any newmem code in aobinjection scripts.

edit:
To only name a few of many who have helped me understand stuff, Alot of the posts from++Methos, ParkourPenguin, Zanzer, mgr.ingz.Player and Darkbyte are that of helping people understand their CE problems, use the search with their name and look at their past posts. even though this isnt really a method of finding an exact problem, im positive you will learn alot.

dissect data/structures can be a pain, but once you've done it a few times and got into the swing of it, you will get more efficient at finding filters and picking out values of things you are looking for.
