Thanks for that info but the additional viewpoint code causes a crash. Maybe I could send all the entities anyway and filter out the non visible ones client-side?

What you need to do is merge the PVS/PAS of the bot and the player. SetupVisibility() is where the server DLL can set the PVS to be used in AddToFullPack(). The default implementation just asks the engine to calculate the PVS for the current view entitity. You could ask the engine to calculate the PVS for two viewpoints, but if the engine's implementation of SV_SetFatPVS() is the same as Quake's then this won't work: the PVS is cleared at the start of each call. What you can do is memcopy() the PVS calculated into a buffer and bitwise-or each additional PVS you need, then return a pointer to the buffer. I'm almost certain this would work, although I haven't tested it :) Something like this (again, untested): void SetupVisibility( edict_t *pViewEntity, edict_t *pClient, unsigned char **pvs, unsigned char **pas ) { Vector org; edict_t *pView = pClient; static unsigned char visBuffer[MAX_MAP_LEAFS / 8]; // Find the client's PVS if ( pViewEntity ) { pView = pViewEntity; } org = pView->v.origin + pView->v.view_ofs; if ( pView->v.flags & FL_DUCKING ) { org = org + ( VEC_HULL_MIN - VEC_DUCK_HULL_MIN ); } *pvs = ENGINE_SET_PVS ( (float *)&org ); *pas = ENGINE_SET_PAS ( (float *)&org ); memcpy( visBuffer, pvs, MAX_MAP_LEAFS / 8 ); for (/* each additional viewpoint */) { *pvs = ENGINE_SET_PVS( /* viewpoint */ ); for (int i = 0; i < sizeof pvsBuffer; i++) pvsBuffer[i] |= pvs[i]; } *pvs = pvsBuffer; }From: TheLazy1 <[EMAIL PROTECTED]> What I'm trying to do is add split screen play to half-life deathmatch, currently I have the client rendering from the view of a bot which in the future will be controlled by additional players through player 1. The problem is that once player one leaves the area of the player two bot, the entities in the bot's view disappear. // Ignore if not the host and not touching a PVS/PAS leaf // If pSet is NULL, then the test will always succeed and the entity will be added to the update if ( ent != host ) { if ( !ENGINE_CHECK_VISIBILITY( (const struct edict_s *)ent, pSet ) ) { return 0; } } Commenting that code "fixes" the problem but also causes the client to render every entity in the level causing a noticable drop in performance. Are there any ways around this? _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlcoders----------------------------------------- Email sent from www.ntlworld.com Virus-checked using McAfee(R) Software Visit www.ntlworld.com/security for more information _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlcoders
