Events/TSFS

In TS, Events become a separate section, so Triggers can have multiple Events with up to two parameters. The game assumed the Trigger, Event and Action all share the same ID. So a Trigger which has ID 12451245 uses the Event list with ID 12451245.

The following Events are available:

Code 1	Event	Parameter types
		#1 (P1)2	#2 (P2)
0	None	0	0
	No Event - cannot be activated.
1	Entered by	0	House#
	Any unit belonging to house P2 enters attached building or cell tag. Use -1 to denote any house. Note: When attaching a trigger with this event to a cell tag, flying or cloaked units entering the cell won't trigger this event.
2	Spied Upon	0	0
	A spy has entered the attached building.
3	Thieved by	0	0
	Obsolete. Presumably intended to trigger when an infantry with Thief=yes infiltrates the attached refinery or silo.
4	Discovered by player or destroyed	0	0
	The attached object is discovered by the human player or destroyed by anything.
5	House Discovered	0	House#
	Any object belonging to house P2 is discovered by the player.
6	Attacked by enemy	0	0
	Attached object or its owner house's base is attacked by enemy fire. A base attack is triggered when any non-insignificant building that is not a deployed unit is attacked by an enemy. For example, if this trigger is attached to a unit, it can fire if the unit owner's base gets attacked regardless of whether the unit itself is attacked or not. Unlike in Red Alert, this event doesn't require for the house to be the player house. In both cases, incidental damage and friendly fire are ignored.
7	Destroyed by enemy	0	0
	Attached object is destroyed by enemy fire. Incidental damage and friendly fire are ignored. See also Events 29 and 48.
8	Any event	0	0
	No condition, triggers immediately. Note: This event may oerride other events occurring at the same time. It's recommended to use event 13 ("Elapsed time...") with 0 seconds instead.
9	Destroyed, Units, All	0	House#
	All units of house P2 are destroyed (does not include civilian objects).
10	Destroyed, Buildings, All	0	House#
	All buildings of house P2 are destroyed (does not include civilian objects).
11	Destroyed, All	0	House#
	All objects of house P2 are destroyed (does not include civilian object).
12	Credits exceed	0	credits
	HOUSE3 has at least P2 credits.
13	Elapsed time	0	time
	P2 seconds4 has passed since this trigger was enabled. If the trigger is repeating, this timer is reset on every loop.
14	Mission timer expired	0	0
	Timer expires.
15	Destroyed, Buildings, #	0	counter
	Exactly P2 buildings owned by HOUSE have been destroyed (does include civilian objects).
16	Destroyed, Units, #	0	counter
	Exactly P2 units owned by HOUSE have been destroyed (does include civilian objects).
17	No factories left	0	0
	HOUSE has no structures with valid Factory set.
Code 1	Event	Parameter types
		#1 (P1)	#2 (P2)
18	Civilians evacuated	0	0
	Civilian objects owned by HOUSE have left the map (See CivEvac ).
19	Build building type	0	Building#
	Building whose internal index is P2 is placed on the map.
20	Build unit type	0	Unit#
	Unit whose internal index is P2 is placed on the map.
21	Build infantry type	0	Infantry
	Infantry whose internal index is P2 is placed on the map.
22	Build aircraft type	0	Aircraft#
	Aircraft whose internal index is P2 is placed on the map.
23	Leaves map (team)	1	TeamType
	Team with index P1 leaves the map.
24	Zone entry by	0	House#
	Attached CellTag's zone entered by house P2. Zones are continuous areas bounded by cliffs and other impassable terrain.
25	Crosses horizontal line	0	House#
	House P2 crosses the horizontal line of the attached CellTag. Note: In this context, "horizontal" refers to the cell grid's horizontal (X) axis, not the apparent left–right axis. It runs from top-left to bottom-right.
26	Crosses vertical line	0	House#
	House P2 crosses the vertical line of the attached CellTag. Note: In this context, "vertical" refers to the cell grid's vertical (Y) axis, not the apparent top–bottom axis. It runs from top-right to bottom-left.
27	Global is set	0	Global#
	Global variable with index P2 is set. Takes priority over other events5.
28	Global is clear	0	Global#
	Global variable with index P2 is cleared. Takes priority over other events5.
29	Captured or destroyed	0	0
	Attached object is captured or destroyed by anything. See also Events 7 and 48.
30	Low power	0	House#
	House P2 is in a low power situation.
31	Attached bridge destroyed	0	0
	Attached bridge destroyed. To link a trigger to a bridge, place the CellTag under any of the bridge overlays.
32	Building exists	0	Building#
	Building with internal number P2 is preplaced, deployed or ordered (icon clicked on in sidebar) onto the map by HOUSE.
33	Selected by player	0	0
	Attached object is selected by the player (single-player only).
34	Comes near waypoint	0	Waypoint#
	Attached object comes within 1,000 leptons (3-4 cells) from waypoint P2.
35	Enemy In Spotlight	0	0
	Enemy unit enters the spotlight cast by the attached building. The attached tag(s) must be set to repeat. This event will also trigger if an enemy unit attacks the building after an enemy unit has entered its spotlight. The attacker doesn't have to be the same unit that entered the spotlight. In case they are the same unit, then the spotlight will also snap at the attacker regardless of the spotlight's current position or trajectory, provided that the attacker is within range of the building. Note: This event cannot coexist on a trigger with an event that checks for an attack on or destruction of the building, e.g. event #6. Doing so will cause the game to freeze sometime after the tower is attacked. See also event 54.

36	Local is set	0	Local#
	Local with index P2 is set. Takes priority over other events5.

Code 1	Event	Parameter types
		#1 (P1)	#2 (P2)

Events take two unsigned integers as parameters, which default to 0.

Notes

¹ ↑ This column specifies the code to be written in the Event's "condition" slot, e.g. E1 in the Events page.

² ↑ P1 is a boolean variable, which denotes whether P2 refers to a TeamType (value 1) or not (value 0).

³ ↑ HOUSE in this document refers to the house owning the Trigger, labeled "HOUSE" in the Triggers page.

⁴ ↑ on default game speed (15 FPS)

⁵ ↑ By default, events are checked in the order they are listed. However, when using local or global variable checks together with other events, the variable check will reset any preceding events. In other words, the variable check is of higher priority than other events. Only after the variable is set/cleared do other events count towards the execution of the trigger.

Referencing items

As you probably noticed, some of the Parameter descriptions in this table end with "#". The reason for that is:

Some parameters take their values to be indexes of objects, others assume they are the identifiers of those objects.

For convenience, if the parameter's description in the table ends with a "#" symbol, you should use the object's index in its appropriate list, otherwise you should use its ID.

Also note: All entries in column P7 are expected to be literal, so you have to convert all the numbers into letters like this:

0 is "A", 1 is "B", 25 is "Z", 26 is "AA", just like the columnm numbering in your favourite spreadsheet program.
