s_PreserveEnts

Stub

This article or section is a stub. You can help by expanding it.

In multiplayer Source games, during a round reset, all entities are resetted to their defaults by being deleted then respawned, unless their current classnames matches an entry in the whitelist s_PreserveEnts. Whitelisted entities either has special code to handle the resetting process, and isn't ideal to be deleted.

Some whitelist entities however don't account round resets properly with their new behavior, so when a round reset occurs, their properties are carried over from the last round, like their origins.

Todo: Attempt to finish this table. Some games might not have any way to reset the round (even throughmp_forcewinormp_restartgamecommands).
