Note: This only works in versions earlier than v1.16f. Also, this procedure requires editing a game file; creating a backup copy of the file before proceeding is recommended. With a text editor, edit the "script.slc" file in the "\ctp_data\default\gamedata" folder. Add the following lines to the file.
trigger 'DOR_T_Give_Gold' when (IsHumanPlayer(g.player) && (player.1.gold<=200000)) { AddGold(g.player,1000000); }
