Anyway to switch a whole players triggers onto another players instead of going into each trigger and changing its value to a diff player?

for example..

player 8 owns 50 triggers each with about 50 more actions all using player 8...i want those triggs including actions to be xfered to player 12

Notepad -> replace.

Use SCMD2's trigedit which is a text trigger editor.

But be careful, P12 cannot own triggers. You have to retain owner P8 and let it execute actions affecting P12.
And also be careful because most of the actions do not work for P12. As a general rule P12 cannot execute actions that only affect current player.

Usually you should make triggers that use current player as much as possible, because then you just need to change the owner and it will work the same (for players 1-8).

Just take your triggers, figure out exactly what needs to be replaced, then you can quickly run through all the triggers replacing them. In many cases this can make triggering a map much faster, as you can simply name all the locations for players the same name, but like P2 instead of P1, and then quickly copy triggers.
