Setting player's camera

Hello, I am newbie, but I really cant get this problem solved.
I want the player's camera, that I can change any way I want (3rd person for example). I tryed to change every game frame like this:

Code:

public OnGameFrame()

{

        GetClientEyePosition(iClient1,vOrigin);

        GetClientEyeAngles(iClient1, vAngles);

        vAngles1 = vAngles;

        GetAngleVectors(vAngles, vAngles1, NULL_VECTOR, NULL_VECTOR);

        NormalizeVector(vAngles1, vAngles1);

        vOrigin[0] = vOrigin[0]-vAngles1[0]*100;

        vOrigin[1] = vOrigin[1]-vAngles1[1]*100;

        vOrigin[2] = vOrigin[2]-vAngles1[2]*100;

        TeleportEntity(iEntity, vOrigin, vAngles, NULL_VECTOR);//iEntity is a camera

}

it would work perfect... if there werent freezes(maybe works better on 100 tick). But I understood that its a bad idea. Next step I tryed to use SetParent:

Code:

public Action:CreateCamera(iClient, args)

{

        iEntity = CreateEntityByName("point_viewcontrol_survivor");        

        DispatchSpawn(iEntity);

        ActivateEntity(iEntity);

        SetVariantString("!activator"); 

        AcceptEntityInput(iEntity, "SetParent", iClient, iEntity, 0);

        TeleportEntity(iEntity, Float:{ -200.0, 0.0, 70.0}, Float:{ 0.0, 0.0, 0.0}, NULL_VECTOR);

        iCamRef[iClient] = EntIndexToEntRef(iEntity);

        AcceptEntityInput(EntRefToEntIndex(iCamRef[iClient]), "Enable", iClient);

}

It works MUCH better (with some freezes also), but... the rotate point of camera is wrong. The camera rotates around pivot point in the feet. I tryed to google for many days and I didnt find any way to change the rotate point(maybe I am looking bad).
I aslo tryed this code:

Code:

        new hOwnerEntity = GetEntProp(client,Prop_Send,"m_hOwnerEntity");

        SetEntProp(client, Prop_Send, "m_hViewEntity",hOwnerEntity);

        SetEntProp(client, Prop_Send, "m_iObserverMode", 4); // 4 is First person

but I become some kind of spectator and cant shoot and jump.

Maybe its bad idea to use sourcemod for this? Maybe I should use vscript some way? I really dont have any ideas. Pls haelp :shock:

Re: Setting player's camera

Maybe it help:
https://forums.alliedmods.net/showthread.php?t=297161

++ (from @Silvers)

Code:

// Hooked 3 times, because each alone is not enough, this creates the smoothest play with minimal movement stutter

SDKHook(client, SDKHook_PostThinkPost, onThinkFunk);

SDKHook(client, SDKHook_PreThink, onThinkFunk);

SDKHook(client, SDKHook_PreThinkPost, onThinkFunk);

Is it L4d1 or 2 ?

Re: Setting player's camera

Thank you for answer. The Lux's plugin was the first thing I explored. My 2nd code from previous post is code I writed after reading Lux's .sp. But the problem is, when I SetParent the camera to player, camera rotates around the foots, not around the center of the player.

I don't really know how to work with SDKHook_PostThinkPost, but I found one function in Lux's plugin:

Code:

public Hook_OnPostThinkPost(iClient)

{

        if(!AreClientCookiesCached(iClient))//block everything until async stuff is done

                return;

        

        

        if(!IsPlayerAlive(iClient) || GetClientTeam(iClient) != 2 || !bClientPov[iClient] || !bShouldBePov(iClient))

        {

                if(!IsValidEntRef(iCamRef[iClient]))

                        return;

                

                if(hClientDisableView[iClient] != INVALID_HANDLE)

                        return;

                        

                hClientDisableView[iClient] = CreateTimer(1.0, DisableView, GetClientUserId(iClient));

                

                DisableCam(iClient);

                return;

        }

        else

        {

                if(!IsValidEntRef(iCamRef[iClient]))

                        if(!CreateCamera(iClient))

                                return;

                

                static iModelIndex[MAXPLAYERS+1] = {0, ...};                

                if(iModelIndex[iClient] != GetEntProp(iClient, Prop_Data, "m_nModelIndex", 2))

                {

                        iModelIndex[iClient] = GetEntProp(iClient, Prop_Data, "m_nModelIndex", 2);

                        SetVariantString("eyes");

                        AcceptEntityInput(EntRefToEntIndex(iCamRef[iClient]), "SetParentAttachment");

                }

                

                EnableCam(iClient);

        }

}

I must make something like this 3 times? It is possible to make this work for every-game-frame method? (really don't understand what exactly this function does ^^")

My game is L4D2.

Re: Setting player's camera

You have to move code of your "OnGameFrame" to a callback of these 3 SDKs. All SDKs shoud point to the same callback. You can see using example in this plugin.
Executing code on each game frame is a very CPU expensive operation.

As about your second code, here is a description of all "point_viewcontrol_survivor" properties:
https://developer.valvesoftware.com/...ntrol_survivor
You can try something, like "SetLocalOrigin".

Also, isn't

Code:

TeleportEntity(iEntity, Float:{ -200.0, 0.0, 70.0}, Float:{ 0.0, 0.0, 0.0}, NULL_VECTOR);

in your code what you was looking for?
X = -200.0, Y = 0.0, Z = 70.0 ? Try change Y.

Also, some discussion and almost finished L4D1 port of Lux's plugin can be found here. Maybe it can help you somehow.

Re: Setting player's camera

I think you don't understand my problem properly - my camera rotates around pivot point. When I making SetParent to player its choosing the axises of pivot from player model. Pivot of player's model located at the foots. So any changes of origin and angles - won't help becase the problem is in the parent. Maybe I can some way attach to the standart camera entity (if it's exist) or any another entity that in the center of player?
My target - is to have custom thirdperson view like in Resident Evil from the shoulder.
P.S. I also tryed those function instead of game frame:

Code:

SDKHook(client, SDKHook_PostThinkPost, onThinkFunk);

SDKHook(client, SDKHook_PreThink, onThinkFunk);

SDKHook(client, SDKHook_PreThinkPost, onThinkFunk);

and it was still laggy.

Re: Setting player's camera

To control third person camera there are ConVars (unfortunately, it's client side only):

Code:

c_thirdpersonshoulderoffset 20.0

c_thirdpersonshoulderaimdist 120.0

c_thirdpersonshoulderdist 40.0

c_thirdpersonshoulderheight 5

cam_ideallag 0

cam_idealyaw -5

cam_idealdist 20

Maybe it will help you.
