Hello, I am running a deathmatch server.

I would like to know if it's possible to create a plugin that will utilize a sprite as a spawn effect possibly a smoke sprite or a lighting strike sprite when a player spawns or respawns? Versus the standard glow or even both running in tandem would be cool as well.

The effect would last as long as the preset spawn protection time set in CSDM.
