Ok after a few more tests and goold old code-digging, I got my rockets working. The problem was that I forgot to override the ShouldPredict() method of the missile entity on the client side to return true when the missile is created by the local player. This prevent the missile entity from initializing as a predicted entity. Using cl_predictionlist is also usefull to check if your new entity is predicted for real or not (it should appear in the list). So here are the general steps if you want to predict an new entity, such as a projectile: - Use CBaseEntity::CreatePredictedEntity to create the entity on both the server and client - Make sure you override the ShouldPredict() method in your predicted entity and return true when you need to have it predicted (typically when it's created by the local client) - Make sure you're running the same simulation code on both the client and server else your predicted entity will jitter - Not sure if this is vital, but set rocket->SetPlayerSimulated( player ); on your entity when you create it Hope this will help someone.> From: [EMAIL PROTECTED]> To: hlcoders@list.valvesoftware.com> Subject: Re: [hlcoders] Prediction of projectile-based weapons in Source> Date: Wed, 24 Oct 2007 14:41:23 +0100> > I know this sounds kind of backwards, and doesn't as much fix the> problem as hack around it, but couldn't you make the projectiles> predicted clientside?
