Hello everyone.
Tell me the position where the player's camera is located, first-person view.
How to get the coordinates of the player's camera, first-person view.

The player's eye position is the player's camera position?
GetClientEyePosition(client, pos);

Yes. Usually locate just behind head of player model (depends player model).
GetClientEyePosition

You get common problem when use SDKTools TraceRay function, you will hit player model and you need filter that out.


GetClientAbsOrigin

Origin under feet (depends how player model has created)

Ok. Thanks.

I create an ENT camera on the coordinates of the player's eye:
Code:
int ent_camera = CreateEntityByName("prop_physics_override");
        SetEntityModel(ent_camera, ENT_CAMERA); // 3D model of my camera 
        DispatchSpawn(ent_camera);
        DispatchKeyValue(ent_camera,"classname", "class_vmodel_camera");
        DispatchKeyValue(ent_camera, "solid", "0");
        TeleportEntity(ent_camera, pos, ange, NULL_VECTOR); // position and direction of the player's gaze
Then the problems begin:
I'm trying to get my 3D camera model to follow the player always at the position of their eyes.
Code:
Format(ParentCamera, sizeof(ParentCamera), "%i", client);
        DispatchKeyValue(client, "targetname", ParentCamera);
        SetVariantString(ParentCamera);
        AcceptEntityInput(ent_camera, "SetParent");
But the center of my ENT camera always turns out to be under the player's feet(the camera position is correct, but its center is not where I need it).

Does it change if you set higher ?
pos[2] += 64.0;

Could parenting do something weird... maybe player model parent attachment is another option.

*edit
Or did csgo players have own view entity ?

If you tie a player's skeleton to the bones - this is not good, the bones move - the camera also moves.

Yes, it is changing. But I need to shift the center to properly snap the camera.

There may be an error in the binding code:
PHP Code:
Format(ParentCamerasizeof(ParentCamera), "%i"client);
        
DispatchKeyValue(client"targetname"ParentCamera);
        
SetVariantString(ParentCamera);
        
AcceptEntityInput(ent_camera"SetParent"); 
There may be other methods (other than binding to certain bones and attachments)

I tested between eyes and abs, I got these Z values
Code:
32.310600
96.310600
So difference is 64.

If you are teleporting too soon on player while he spawn for example ?

I'm on my way to work now. I'll come home from work, check it out, and let you know.

Try this:
Code:
SetVariantString("!activator");
AcceptEntityInput(ent_camera,"SetParent",client);
SetVariantString("eyes");
AcceptEntityInput(ent_camera,"SetParentAttachment");
The action of SetParentAttachment will also set the origin, so no need for the teleport either. It is also safe to use ActivateEntity(ent_camera); after DispatchSpawn just in case.

Then, if the offset needs to be modified, you could use the "m_vecOrigin" vector property to set the attachment offset. By default after using SetParentAttachment is 0 0 0. This is not the same as "m_vecAbsOrigin" and it is also different from TeleportEntity.
