There's no built-in way, so you would have to add code to Flatline to make that happen.
ok thanks what's the code for doing the command when the client successfully connects i know the event of successfully connects but the problem is the host never connects to anyone it's the client who connects therefore how can i activate something on host's side if the event is started from the client's side
]]>func host
{
chr_draw_all_characters = 1
}
Then you would be able to call that function from the dev console. See the wiki's global page for more detail.
