I noticed alot of ppl still use playernames metamod plugin to display players names in the center when you put your crosshairs on them. This does the same thing, using hud_centerid. Dunno if u can really count this as a plugin, but here it is n e way lol.
#include <amxmodx>
public client_putinserver(id) {
client_cmd(id,"hud_centerid 1")
}
public plugin_init() {
register_plugin("Playernames","1.0","Anybody" )
}
