[Source code]Stride logging.

Well, I don't think I've ever contributed much to this section. Hope some of you could find some good use of this.

Basically, a stride/primitive count/vertex count recognition. I was able to find the stride in CA, until it crashed ( it's detected for CA ). Yes, I know there are probably alot of these, but I only found 1 and it kept crashing.

This is indeed, copy and paste friendly. Here we go.

Well, that's it.

Just want to say, I put Hook.h last 'cause I wanted to say. I am deeply ashamed for copying most of everything in Hook.h from someone else, I wasn't able to retrieve the device pointer myself, and I found this method somewhere.

I am truly sorry to those of you who hate copy and pasting. Hell_Demon please don't kill me.

The rest was made by me.

Note: If you're wondering why it says "Made by Azu". It's because on Why06's little MSN group, they call me Azu because of my MSN display name.

Second note: If anyone does know how to find the device pointer rather than the address for the virtual method in the d3d9 module, I seek help from you. If you wouldn't mind helping me find the pointer manually.

I guess this is sort of a release/request thread.

wow this is really long seriously for a stride logger
The device pointer shld be stored in IDirect3DDevice9 structure if I'm not wrong(most probably wrong coz I'm rusty)

edit:
spotted this off another site may help

why can't nothing be made to browse through each model and shader it?

Why does noone use
stride = (min+max)/2?!?!

log(n)/log(2) where n is the maximum stride number.
for stride 0 to a 10000 it takes a max of 14 steps.
for stride 0 to 1000000 it tkes a max of 21 steps.

if(m_Stride == stride) //color me green
else if (m_Stride < stride && m_Stride > mins) //color me red
else if (m_Stride > stride && m_Stride < maxs) //color me blue

if its blue, you hit np 6, if its red you hit np 4, if its green u hit whatever key u have set to log the stride lol.

Much faster + you won't skip the correct stride because of lag

no idea who cme up with it, probly azorbix ^^

for comparisation(if u'd be a super human and can check 1 stride per frame):
10000 strides @ 100 fps
Your old method - 10000/100=100, 1 minute and 40 seconds if you'd be able to check 1 stride per frame
New method - log(10000)/log(2) = 14, 14/100 = about 1/6th of a second

What does stride logging do??

Is it something that you can alter to change the speed of the player??
