Is there any way to get the entity / entity index a player is pointing at with their crosshairs?

I have looked through the sdk and didn't find anything that looked useful. I may be blind, which is why I am asking.

I just need a function name and the header file its in. I should be able to figure out the rest (vfunc hooking, etc).

I did this with geteyeangles and engine trace. Later Ill post some code if you need it.

Could you post this code?

[awuh0]

sure, I posted it on sourceplugins.

This is from the hook mod that will prolly get released soon.

        class CTraceFilterEntitiesOnlyReally: public CTraceFilterEntitiesOnly
        {
                bool ShouldHitEntity(IHandleEntity*, int)
                {
                        return true;
                }
        };

        void g_PlayerRunCommand(CUserCmd* cmd, IMoveHelper* move)
        {
                if ((cmd->buttons & 32) == 0)
                        RETURN_META(MRES_IGNORED);

                CBasePlayer* player = META_IFACEPTR(CBasePlayer);
                edict_t* entity = g_BaseMap[reinterpret_cast<CBaseEntity*>(player)];
                if (!entity)
                        RETURN_META(MRES_IGNORED);
#if 0
                IPlayerInfo* info = g_PlayerInfoManager->GetPlayerInfo(entity);
                if (!info)
                        RETURN_META(MRES_IGNORED);
#endif
                Vector start = reinterpret_cast<SBasePlayer*>(player)->EyePosition();
                Vector end;
                AngleVectors(reinterpret_cast<SBasePlayer*>(player)->EyeAngles(), &end);
                end.NormalizeInPlace();
                end = start + end * 64;

                Ray_t ray;
                ray.Init(start, end);

                CTraceFilterEntitiesOnlyReally filter;
                trace_t result;
                g_EngineTrace->TraceRay(ray, MASK_SHOT, &filter, &result);

                H_CONPRINTF("Hit: 0x%x\n", result.m_pEnt);

                edict_t* target = g_BaseMap[result.m_pEnt];
                if (!target)
                        RETURN_META(MRES_IGNORED);

                int index = g_Engine->IndexOfEdict(target);
                H_CONPRINTF("Hit: %s\n", g_Engine->GetClientConVarValue(index, "name"));

                RETURN_META(MRES_HANDLED);
        }

What am I doing wrong? With this, it sometimes says I'm hitting myself, and I have to aim really weird to hit another player.

Oh, and is there any simple way to visualize the ray? I tried turning on r_visualizetraces but it's not very helpful.

Your problem is on this line...

instead of that line do the following

// before you trace the ray you want to move the start point out of the players body
start += end*64;
// And set the maximum distance you want to trace too.
Vector end = start + end*10000000;

Also, to my knowledge there is no CTraceFilterEntitiesOnlyReally
I have seen; CTraceFilterEntitiesOnly, CTraceFilterWorldOnly, CTraceFilterWorldAndPropsOnly, and CTraceFilterHitAll

And no, sorry Im not aware of any way to visualize it other than using the effects->beam and feeding it the same inputs.

You could just enable temp_ents. There is a code posted by mani for windows and linux to get it working. I am going to sigscan it though.
