I did something similar to this in Project Valkyrie for all projectiles that don't need special functionality like seeking. Essentailly I have a manager that runs on both the client and the server, which handles the projectiles moving and doing traces for damage etc, and the client handles the visual representation. You still have to create a client-side entity for each projectile if you want to display a model though.
Additionally, I have a system in the gamerules that networks a projectile index to keep them in sync; Every projectile when it's created is then assigned the same ID ( ie: when a client projectile is created in prediction, it gets the new ID from the networked gamerules list) which the server also pulls from. Eventually this number gets cycled back down. Then when the client receives an event from the server saying the projectile has impacted, it has an ID so that it knows which one to terminate. This system works really well, and if you're not using a lot of model based projectiles, or insane particle effects, it's capable to have thousands of projectiles active without any major perf hit. Unfortunately, in Valkyrie, some of the effects are a little heavy, and due to the development time taken, they were never really optimized, so Valkyrie still hits a rendering bottleneck with them. I had done another test for simulating just "bullets" (only the impact rendering, and occasionally a tracer if desired) for a properly simulated ballistic system, it worked quite well, but I never rolled it out into any production environment, as nothing I have ever worked on has really needed it. It still has some issues with losing synchronization over drastic angle changes, but it performs extremely well. -Tony On Sun, May 20, 2012 at 1:35 PM, Psy_Commando <psycomma...@gmail.com> wrote: > Hello, I was wondering if it was possible to use the technique the > left4dead devs used for the infected, to handle non hitscan bullets ? > The technique I'm talking about was referenced in an article on the vdc : > "If you're creating lots of individual objects all the time, consider > rolling them all into a single manager entity.
