The NGLE Manual
Countdown
Timer
By Cook
The screen timer in TRNG only
counts up. If you want a countdown timer use the ACTION
trigger, "Enemy. Timer. Show the trigger count-down for <#>
enemy using (E)format".
Once Lara uses the switch in the room below she has only 5
seconds to get out the door before the door closes. I am
going to use the "Enemy. Timer. ..." ACTION trigger to show
the seconds ticking down.

On the sector with the LEVER_SWITCH I have placed an ACTION
trigger to open the door. I have used an ACTION trigger
instead of an OBJECT trigger since with the ACTION trigger
the door is opened whenever the LEVER_SWITCH is used. With
the OBJECT trigger the door is only opened if the
LEVER_SWITCH is used from one side.

On the same sector I place the ACTION trigger, "Enemy.
Timer. Show the trigger count-down for <#> enemy using
(E)format". Select the door in the "(Object to trigger
<#>):" dropdown box and select the format of the timer in
the "(E)xtra:" dropdown box of the Set Trigger Type window.

On the same sector I place a TIMER_FIELD trigger with the
value +005 seconds selected in the "(Object to trigger
<#>):" dropdown box. Leave the "Timer (Parameter<&>):"
dropdown box as 0. You can use the TIMER_FIELD trigger to
set a timer value for an object that does not use the timer
field. This prevents the "Cannot overlap special triggers"
warning.

Finally I place a SWITCH trigger on the sector for the
LEVER_SWITCH.

Unlike the screen timer, the enemy timer text position and
colour can be changed with the TextFormat= script command or
the Text FLIPEFFECT triggers.

5 seconds to get to the door.

Lara is not going to make it.

It's possible to have the screen timer and enemy timer on
screen at the same time.

You cannot use the Timer CONDITION trigger with the enemy
timer but you could trigger an Organizer at the same time as
the enemy timer to control events.
