snippets of cycript code for messing with wow's rendering (client version 3.3.5a / build 12340)

wotlk.cy.js

// here i am getting a pointer to the games camera, starting from 
// s_currentWorldFrame which has a known address in the games memory.
// that static variable points to an instance of CGWorldFrame, which
// houses a lot of the rendering stuff, including the camera. the
// camera, among other things, has a variable for the field of view
// which is what ends up at *fovptr.

var s_currentWorldFrame = @encode(int*)(0xEEEA8C) // static pointer to active world frame
var m_camera = 32280; //offset of cgcamera pointer in worldframe object
var m_fov = 64; // offset of fov (field of view) value in cgcamera object (just a floating point number)

var cgcam  = @encode(int*)   (*s_currentWorldFrame + m_camera);
var fovptr = @encode(float*) (*cgcam + 64);

*fovptr = 4.0 // huge
*fovptr = 0.5 // small

// these are integer bitfields that control rendering settings. that is,
// each bit in these variables turns something on or off. these are where
// most of the weird effects in the video comes from
var unk_s_enables = @encode(int*)(0xda0d08)
