What's chams?

Chams are short for, chameleons. it's basically a wallhack, with a color overlay for the item's place on the Z Axis, behind, or in front of the Render Buffer.

NOTE: If you're going to be using a D3D Base, you'll have to change the Device name, and make sure that your arguments for DrawIndexedPrimitive match.

But, first we will need to define our playerbody, so that we don't cham parts of the map and only the player.


this can be done like this:

Kod:


UINT Stride;
#define Player (Stride == 44);
bool Chams = false;


Also, for better definition of the playerbody using numverts and primcounts, or if there are more than one stride, you can use this code

Kod:


UINT Stride;
UINT NumVertices;
UINT PrimitiveCount;
#define Player (Stride == 44 || Stride == 20 || NumVertices == 200 || PrimitiveCount == 30);
//NOTE, these are Fake Strides.
//You will have to use the Game Specific ones for the game  you are planning to 'hack'
bool chams = false;



DrawIndexedPrimitive

Kod:


  LPDIRECT3DVERTEXBUFFER8 Stream_Data;
  UINT Stride = 0;

  if (m_pD3DDev->GetStreamSource(0, &Stream_Data, &Stride) == D3D_OK)
  Stream_Data->Release();

if(Chams)
      if(Player)
      {
          {
//If the player stride is active.
    DrawIndexedPrimitive(Device, Type, MinIndex,  NumVertices, StartIndex, PrimitiveCount);
//If it's behind the wall, then fill it with Green
    Device->SetRenderState( D3DRS_ZENABLE,false );
    Device->SetTexture( 0, texGreen );
//and then disable the Z Axis buffer, and bring them to the front.
    DrawIndexedPrimitive(Device, Type, MinIndex, NumVertices, StartIndex,  PrimitiveCount);
//if the player is in front of the wall
    Device->SetRenderState( D3DRS_ZENABLE, true );
//turn the Z Buffer back on, and then fill the playermodel with blue
    Device->SetTexture( 0, texBlue);
    DrawIndexedPrimitive(Device, Type,  MinIndex,  NumVertices, StartIndex, PrimitiveCount);
          }
      }
