 1 | # OneByteWallhack
 2 | CS:GO wallhack achieved by patching one byte of game memory. Written in Python 3.
 3 | 
 4 | This does the same as **r_drawothermodels 2** command but without touching the cvar, so it's VAC - safe.
 5 | 
 6 | ## How it works
 7 | This program patches assembly code produced by compiling the [following line of the game code](https://github.com/ValveSoftware/source-sdk-2013/blob/0d8dceea4310fde5706b3ce1c70609d72a38efdf/mp/src/game/client/c_baseanimating.cpp#L3149):
 8 | ```cpp
 9 | int extraFlags = 0;
10 | if ( r_drawothermodels.GetInt() == 2 )
11 | {	
12 |     extraFlags |= STUDIO_WIREFRAME;	
13 | }
14 | ```
15 | 
16 | The **r_drawothermodels** check is modified to make the `if` expression evaluate to **true** when **r_drawothermodels** cvar is set to default value (1).
