ESP isn't being drawn properly onto players, unless the escape menu is open?

[HOTD]

Title. ESP positions are off but when you open the pause menu, they are corrected to the right positions.

Hello,

Can you please post a video showing this issue?
I can't seem to replicate it on my end

[HOTD]

Sorry for the late reply, haven't been playing gmod a lot. The ESP seems to acting strange with or without the escape menu, seems to be rendering in the wrong positions (trying to find my screenshots of this) or not rendering at all. When you open the escape menu it fixes it (https://i.imgur.com/q3aFP4G.png).

Here's a video: https://www.youtube.com/watch?v=FnJxVdYeVRw

Here's the video of the boxes rendered in the wrong areas: https://www.youtube.com/watch?v=08i1xmCqg4I

Does replacing esp::draw_bounding_box with esp::draw_3d_box fix the issue?

[HOTD]

Nope, https://www.youtube.com/watch?v=eGgDOz4fWII. I do like the 3D boxes though.

Looks like an issue with the view matrix.
Can you post the server IP?

[HOTD]

92.60.12.133:27015 or 92.60.12.133:10000 . Zombie.Zone ZS Server 1 & 2

[HOTD]

Edit: Still having issue on that zs server. I'm out of ideas.

[FocuzJS]

I've ran into this now aswell, its a server addon type thing it seems

[FocuzJS]

can confirm it's a view matrix issue, player locations are correct for my aimbot

[M-Tass]

Can you check if cam.Start3D fixes the issues?

[FocuzJS]

I was thinking of getting the view matrix another way, and seeing if https://wiki.garrysmod.com/page/Entity/GetWorldTransformMatrix is a different vmatrix than globals::engine->get_view_matrix()

how would cam.Start3D help, it's lua aswell right?

[M-Tass]

GetWorldTransformMatrix isn't the view matrix rather the rgfl_CoordinateFrame

If I'm not mistaken cam.Start3D seems as if it calls CViewRender::SetupMain3DView (Which re-calculates the view matrix and caches it)

[FocuzJS]

cam.Start3D says it expects cam.End3D to be called. Should this be called directly after since im guessing the cache will be updated or on an event hook?
and how often do you think this call should be made, once per run or as part of get_view_matrix?

[M-Tass]

See if this works:

cam.Start3D(LocalPlayer():EyePos(), LocalPlayer():EyeAngles(), ...)
auto& matrix = globals::engine->get_view_matrix()

// ESP rendering

cam.End3D()

[M-Tass]

Using cam.Start3D does indeed solve the issue

yes it works for me aswell. Start3D has defaults defined so passing it tables is not necessary. I was able to get this working with few simple lines wrapped around get_view_matrix since i suspected it was the only issue.
my fix thanks to your tip:

    auto glua = globals::lua->create_interface(lua::type::client);

    if (glua) {
        glua->PushSpecial(lua::special::glob);
        glua->GetField(-1, "cam");
        glua->GetField(-1, "Start3D");
        glua->Call(0, 1);
        glua->Pop();
    }
    auto& matrix = globals::engine->get_view_matrix();
    if (glua) {
        glua->GetField(-1, "End3D");
        glua->Call(0, 1);
        glua->Pop(3);
    }

and then render esp normally so in my case, i don't have multiple lua contexts open at once! thanks for the quick responses.

Sorry, I mistakenly closed this issue. Opening it again
If the issue is resolved on @HOTD's end, they may close it

[FocuzJS]

just tested on the servers he had trouble with before. everything looks good to me

[xbread]

@FocuzJS you got a discord that i can message you on?

[FocuzJS]

@xbread post yours i'll add you

[HOTD]

Seems to work. Closing.
