Need help with DrawModelExecute

[affenaff]

Hey, I'm trying to hook DrawModelExecute. And in my hook, when i dont call the original one, I wont crash but obviously all my models are invisible. So when i try to call the original like i do with other hooks, my game just crashes. Attaching a debugger, I'm getting "Exception thrown at 0x0C9FBD96 (engine.dll) in csgo.exe: 0xC0000005: Access violation reading location 0x000A0503.

Don't really know what that's suposed to mean.
Anyways, here's my hook.

void __stdcall Hooks::Hooked_DrawModelExecute(void* context, void* state, const ModelRenderInfo_t &pInfo, SourceEngine::matrix3x4_t *pCustomBoneToWorld)
{



oDrawModelExecute(context, state, pInfo, pCustomBoneToWorld);

}

Thanks in advance

How do you initialize the hook?

How do you initialize the hook?

In my hook.h

typedef void(__stdcall * DrawModelExecuteFn)(void*, void*, const ModelRenderInfo_t&, SourceEngine::matrix3x4_t*);

extern DrawModelExecuteFn oDrawModelExecute;

void __stdcall Hooked_DrawModelExecute(void* context, void* state, const ModelRenderInfo_t &pInfo,SourceEngine::matrix3x4_t *pCustomBoneToWorld);


in my hook.cpp

std::unique_ptr<VFTableHook> g_ModelRender = nullptr;

DrawModelExecuteFn oDrawModelExecute = nullptr;

g_ModelRender = make_unique<VFTableHook>((PPDWORD)SourceEngine::In terfaces::ModelRender(), true);

oDrawModelExecute = g_ModelRender->Hook(21, (DrawModelExecuteFn)Hooked_DrawModelExecute);


this is what I do. When i put another hook in like overrideview or painttraverse, it worked flawlessly. So im clueless.
It most likely has something to do with calling the original one though.

I think you're reading from the "0x000A0503" address in memory which you don't have permission to do, check for nullptr's and such. I'm not so good at hooking so i don't really know what it is but i assume it's that.

You also have a really nice name + country, insta +rep

idk but , try removing what @affe2626 said and that Interfaces::ModelRender(), ture
