I need to make it so that whenever chief walks up to a certain device, an option appears, like if you were to activate a switch, then I need to make it so that explosions go off at certain points after that. How would I script this?

Also, how can I make a countdown timer?

Additionally, I need to make it so that when chief walks into a certain trigger volume, the effect it generates (Bsp switch etc.) only triggers after chief activates above switch.

Thanks.

Four words Easy Halo scripter v2

I don't think the easy halo scripter v2 creates a countdown timer...
Sorry, but I don't know how. I would like to learn though.

Easy Halo Scripter V2 does not tell you how, But I do.

(hud_set_timer_time 2 30)
(hud_set_timer_warning_time 1 00)
(hud_set_timer_position 0 0 bottom_right)
(show_hud_timer true)

(hud_set_timer_time 2 30) sets the time for the timer. Replace "2" with the ammount of minutes you want. Replace "30" with the amount of seconds. The (hud_set_timer_warning_time 1 00) sets the time when the timer flashes red. Replace "1" with the amount of minutes you want. Replace "00" with the amount of seconds. (hud_set_timer_position 0 0 bottom_right) sets the positions. Replace bottom_right with something like bottom_left or bottom_right again, I think the possibilities are: bottom, top, left, right, bottom_left, bottom_right, top_left, top_right (I haven't experimented with this yet). The 0 0 in (hud_set_timer_position 0 0 bottom_right) is probably the offset in x,y coordinates. You'll need to ask a good scripter about that also.

Easy Halo Scripter V2 doesn't but v3 does
