Thanks u rwby, unfortunately i don't know anything about internal so i'll not do anything on it, i'll continue to learn external to help back the community

Internal isnt that hard to learn. If you are interested in a proper Internal knife changer ill get you started.

Code:

void RecvProxy_Viewmodel(const CRecvProxyData* pData, void* pStruct, void* pOut)
{
	int iModel = pData->m_Value.m_Int;

	int cCTDefault = MPGHContribV2.m_pModelinfo->GetModelIndex("models/weapons/v_knife_default_ct.mdl");
	int cBayonet = MPGHContribV2.m_pModelinfo->GetModelIndex("models/weapons/v_knife_bayonet.mdl");
	int cGut = MPGHContribV2.m_pModelinfo->GetModelIndex("models/weapons/v_knife_gut.mdl");
	int cTDefault = MPGHContribV2.m_pModelinfo->GetModelIndex("models/weapons/v_knife_default_t.mdl");
	int cButterfly = MPGHContribV2.m_pModelinfo->GetModelIndex("models/weapons/v_knife_butterfly.mdl");
	int cGunGame = MPGHContribV2.m_pModelinfo->GetModelIndex("models/weapons/v_knife_gg.mdl");
	int cFlip = MPGHContribV2.m_pModelinfo->GetModelIndex("models/weapons/v_knife_flip.mdl");
	int cM9Bayonet = MPGHContribV2.m_pModelinfo->GetModelIndex("models/weapons/v_knife_m9_bay.mdl");
	int cFalchion = MPGHContribV2.m_pModelinfo->GetModelIndex("models/weapons/v_knife_falchion_advanced.mdl");
	int cKarambit = MPGHContribV2.m_pModelinfo->GetModelIndex("models/weapons/v_knife_karam.mdl");
	int cDagger = MPGHContribV2.m_pModelinfo->GetModelIndex("models/weapons/v_knife_push.mdl");
	int cHuntsman = MPGHContribV2.m_pModelinfo->GetModelIndex("models/weapons/v_knife_tactical.mdl");

	C_BaseEntity *localPlayer = (C_BaseEntity*)MPGHContribV2.m_pEntlist->GetClientEntity(MPGHContribV2.m_pEngine->GetLocalPlayer());
	if (localPlayer)
	{
		if (MPGHContribV2.m_pEntity->GetBaseCombatWeapon(localPlayer))
		{
			if (iModel == cBayonet
				|| iModel == cButterfly
				|| iModel == cCTDefault
				|| iModel == cTDefault
				|| iModel == cFlip
				|| iModel == cGunGame
				|| iModel == cGut
				|| iModel == cKarambit
				|| iModel == cM9Bayonet
				|| iModel == cHuntsman
				|| iModel == cFalchion)
			{
				//int iKnife = MPGHContribV2.m_pConvars->flknife;

				if (CMDMPGH->getValue("bayonet") == 1)
				{
					iModel = cBayonet;
				}
				else if (CMDMPGH->getValue("flip") == 1)
				{
					iModel = cFlip;
				}
				else if (CMDMPGH->getValue("gut") == 1)
				{
					iModel = cGut;
				}
				else if (CMDMPGH->getValue("karambit") == 1)
				{
					iModel = cKarambit;
				}
				else if (CMDMPGH->getValue("m9bayonet") == 1)
				{
					iModel = cM9Bayonet;
				}
				else if (CMDMPGH->getValue("huntsman") == 1)
				{
					iModel = cHuntsman;
				}
				else if (CMDMPGH->getValue("butterfly") == 1)
				{
					iModel = cButterfly;
				}
				else if (CMDMPGH->getValue("falchion") == 1)
				{
					iModel = cFalchion;
				}
				else if (CMDMPGH->getValue("dagger") == 1)
				{
					iModel = cDagger;
				}
			}
		}
	}

	*(int*)pOut = iModel;
}

After you have your recvprop hook you need to hook it.

Code:

MPGHContribV2.m_pNetVars->HookProp("DT_BaseViewModel", "m_nModelIndex", RecvProxy_Viewmodel);

This wont help you externally in anyway possible but if you decide to take a stab at internal this will help lead you in the right direction.

No problem man

currently there is no public method for changing knife externaly.

MPGHContribV2.m_pNetVars->HookProp("DT_BaseViewModel", "m_nModelIndex", RecvProxy_Viewmodel);

Can you show this?
MPGHContribV2.m_pModelinfo->GetModelIndex
Also
m_pNetVars->HookProp("DT_BaseViewModel", "m_nModelIndex".....)

You get the nModelIndex from weaponBase or from playerBase? or client/engine dll?

IModel != nModelIndex if i'm not so wrong, let me re-make the question, the NetVar->HookProp, get the netvar nModelIndex, and you write to it setting a new number, so that make the Knife Model change, my question is, this netvar, come from where? ("DT_BaseViewModel", k i know that...) I mean, you "find that netvar" inside the weaponbase? if no, where?

Also what the pData->m_Value means, "pData" means? PlayerData?

There is a way to do it externally.
However, as far as i know. The game won't detect your normal knife if you are making Mem.Write<int>(Weapondata + m_Attri + m_item + m_itemdef);
so... that's useless.
But i wen't thru the netvars and saw "m_nModelIndex" which has the offset of "0x254".
I well post back result if i manage to make a knife changer.

Also, you should write the knife viewmodel & worldmodels.

See this pic.
The current knife is actually 42 <--- which should be ct i believe.

so... Mem.Write<int>(Weapondata + m_Attri + m_item + m_itemdef, 507); makes it useless.

Greetings,

Searching through the forums, I read somewhere that External Knifechanger is significantly harder, because you have to change the model right before it draws, and that caused several users to have flikering knives or their normal knife model.

That's just from reading on the forum, hopefully you find a way that suits you

then make a check for karambit aswell

let me show u what i mean.

Code:

if(Weapon == 42) {
 Mem.Write<int>(WeaponData + Attri + Item + ItemDef, 507);
}
if(Weapon == 507) {
// Do iViewModel
// Do WorldModel
}

Code:

if(Weapon == 42 || Weapon == 507) {
 Mem.Write<int>(WeaponData + Attri + Item + ItemDef, 507);
// Do iViewModel
// Do WorldModel
}

EDIT: i do now see bot's using custom knifes.
But not the local player.

Good job viking! When i Will be at home i will look at it.

EDIT: You need to write to modelindex and itll change the model.

Yes, correct, its what i said, but i asked from where nModelIndex come, like PlayerBase, Client.dll, Engine.dll, WeaponBase, but i got no reply from you

Well it came from DT_BaseViewModel, anyways i was trying to do it earlier but even if you wrote to modelindex it wont work online.
