ok first replace all your
g_chase.c code with this code

ent->client->update_chase = true;
UpdateChaseCam(ent);
return;
}
}
gi_centerprintf(ent, "No other players to chase.");
}
next open up g_local.h
and find your gclient_s struct and add this line
int chase_mode;
and thats it.
one thing i would like to
say this is not all my code some came from the action src.
