Why using an array for messages and battlelist creatures?

[Puterin]

Supppp guys, I have been searching some addresses and already finished with chat module (read,talk,channels,statusbar,etc)
But now I've got this question... I have seen that some ppl (posts from 2008 lol) say it's better to put into an array this things:
Creatures from Battlelist (with id,isattacking,etc)
Messages from channels (sender,time,type,etc)

Why this? I mean, I can understand that you want to reduce a little the CPU %, but even doing so you will have to update the array each 500-1000ms (so once again reading that memory and adding them to the array)


From my point of view this is bullsh*... no, just kidding, it's just I don't get it, only that.

Thaaaaaanksssssssss

Or you can just update the cache when needed, instead of adding a timer to it

Wouldn't that take away the entire point of caching it?

No. If you set up a timer to constantly update the battle list, you will be updating this for no reason most of the time.
In the other hand you can just call up a function like "UpdateCache()" when you really do need it.

Or, if you want to get really tricky, you can jump into Kernelland, change the paging table to point one of your memory pages to the same physical address as Tibia's battlelist, and use it as your own. Or just inject like a pr0.

epic XDDDDD


thx guys, I'll do it then =)

Well, they are stored in arrays in Tibia code, so this is the best way to collect the data from the structures, doing the same, XD

If you inject code/dll, you don't need to update the array, because the pointer will point directly to the structure X)
