Trigger Flow and Content Examples
It is best to follow a specific order to design straightforward, intuitive tombs for others to experience. It’s possible to modify the process for what best fits your creative side, but this is a good method with which to begin.

• Design the Layout and Theme for your tomb. Is it going to be a tomb filled with fire? What about a watery graveyard with pools, fountains, and steam traps? Before you get caught up with individual puzzles, and tiny details, know where you’re going to place things and what you want the overall experience to be.
• Build the Tomb and Place all objects: Make sure your traps fit in the tight hallways, there’s plenty of room for your dive wells, and be sure to confirm that there is room for statues to be pushed and pulled towards completion of the puzzle.
• Set up Triggers and Activated Behaviors: Depending on how much thought you put into your puzzles in the earlier steps, this part may be a breeze or quite complicated. There is a very specific flow that must be used here in order for things to work properly.

TIP: In order for the tomb to act like a tomb, you must set up a series of Triggers and Activated Behaviors on the placed tomb objects. It is possible to access these commands by entering Buy Mode, and Ctrl + Shift Left Clicking on objects. Examples will be provided on how to use these commands, but it’s important to explain how to access them in the first place!

Triggers and Activated Behaviors
When you want something to activate something else, essentially a cause and effect, you must first designate a Trigger, then Activated behavior. For example, you want to make it so that when a Sim steps on a floor switch, a door is unlocked.

Floor Switch to Unlock Door

• Place the Door
• Place the floor switch
• Lock the Door using Buy Mode Interactions
• Use the “Link Triggers…Step On” interaction on the Floor Switch
  • Here, you are saying that the Trigger is Step On
• Use the “Link to Activated Behavior…Unlock” interaction on the Door
  • Here, you are saying that the Activated Behavior for the last Trigger is to Unlock

TIPS: The “Link to Activated Behavior” interaction only appears once a Trigger is set. If you want to change what the current trigger is, simply click on an object and select “Reset Current Link.” If you want to see the Triggers current set from an object, hover over the object with the mouse cursor. Lines will be drawn to the connecting objects. If you want to see all triggers set up, select “Triggers…Draw All Links on Lot.”  If you want to delete a Trigger, click the object, select “Triggers…” with the name of the Trigger. When doing “Link to Activated Behavior,” all available Activated Behaviors that have not already been selected from the Trigger object will be displayed.

To further acquaint you with this building system, here are some common tomb object components and setups for you to use. Remember, these are just examples! Triggers and Activated Behaviors can be mixed and matched to create a huge variety of puzzles.

Keystone Panel to Unlock a Door

• Place the Door
• Place the Keystone Panel on the wall near the door
• Place a keystone in the room
• Lock the Door
• Use the “Link Triggers…Insert Keystone” interaction on the Keystone Panel
• Use the “Link to Activated Behavior…Unlock” interaction on the Door
• When inserting the keystone into the Keystone Panel, the door will unlock.

Disable Fire Trap with Steam Trap

• Place a trap on the floor
• Place a trap as close as possible to the first one on the wall
• Place a Floor Switch
• Use the “Set Trap Type…Fire” interaction on the floor trap
• Use the “Set Trap Type…Steam” interaction on the wall trap
• Use the “Set Trap State… Firing and Visible” interaction on the floor trap
• Use the “Set Trap State…Armed and Visible” interaction on the wall trap
• Use the “Link Triggers…Step On” interaction on the floor switch
• Use the “Link to Activated Behaviors…Fire Once” interaction on the wall trap
• The Sim cannot get past the fire trap. However, when the Sim steps on the floor switch, it activates the steam trap which puts water onto the fire trap. The fire trap is now disabled and the Sim can pass!

Use Pushable Statue to Disable Trap

• Place Pushable Statue
• Place trap on the floor
• Use the “Make Visibly Movable – (Currently: None)” interaction on the Pushable Statue
• Use the “Set Trap Type…Electricity” interaction on the floor trap
• Use the “Set Trap State…Armed and Visible” interaction on the floor trap
• The Sim probably doesn’t want to risk walking across this armed electrical trap. The Sim can now push the statue onto the trap, which will disarm it for safe passage!

Use Pushable Statue on Floor Switch to make Floor Switch Appear and unlock Door

• Place Pushable Statue
• Place two floor switches (Switch A and B)
• Place Door
• Lock the Door
• Use the “Hide” interaction on Switch B
• Use the “Make Visibly Movable – (Currently: None)” interaction on the Pushable statue
• Use the “Link Triggers…Step On” interaction on Switch A
• Use the “Link to Activated Behaviors…Appear” interaction on Switch B
• Use the “Link Triggers…Step Off” interaction on Switch A
• Use the “Link to Activated Behaviors…Disappear” interaction on Switch B
• Use the “Link Triggers…Step On” interaction on Switch B
• Use the “Link to Activated Behaviors…Unlock” interaction on the Door
• If the Sim steps on Switch A, Switch B appears! However, it quickly disappears when the Sim gets off Switch A. The solution is to push the statue onto Switch A, which makes Switch B permanently visible. The Sim can now step onto Switch B to unlock the door.
