Hides the popup dialog. Does not disable the device — it can still be shown again.

For several persistent values at once, use canvas HUD text widgets in the HUD tab.

Switches to a specific page in an exclusive HUD group set. Hides all sibling groups and shows only the target — like tabs.

NOTE: all Show Variable HUD / Show HUD Message actions share ONE hud_message_device, so showing several DIFFERENT values overwrites — only the last is visible. To display multiple values at once (score + lives + wave), add canvas HUD text widgets in the HUD tab (one per value) instead of stacking these.

Applies this device's movement settings to the agent.

Assigns the agent (NPC) to follow this patrol path.

Assigns the agent as the driver of the chosen vehicle.

Makes the interacting player the OWNER of one billboard in the variable's billboard array (slot = index, one per village/plot). His per-player value shows on that board and auto-updates on every write. Requires a PLAYER int variable with billboard:true. NEVER combine with claim_zone: claim_zone already claims every bound board (slot Zone-1) — adding claim_billboard would let a player steal a board without owning the zone (V054).

Makes the interacting player the OWNER of zone N (plot/village). One zone per player, one owner per zone, auto-released when the owner leaves. Also claims billboard slot N-1 of every player billboard variable. Gate the zone devices with the is_zone_owner condition. Zones are numbered from 1.

Writes a variable from a formula: target = A <op> B (or += ). Each side is a variable or a number. The `operator` value is the SYMBOL itself: "+" (add), "-" (subtract), "*" (multiply).

Moves to the next (or previous) player and registers them in a Player Reference device — the building block for an admin panel or player selector. The index lives in a GLOBAL number variable you can show on the HUD. Other rules act on the selection via "Is Referenced Player" or "Activate Player Reference". Empty island: does nothing.

Removes the currently spawned vehicle mod box.

Destroys the objective, attributing it to the agent.

Eliminates the triggering agent — player, creature, guard or any agent — by dealing lethal damage (9999 HP) via agent.GetFortCharacter[].Damage(). Acts on the event's agent (no device, no parameter). GetFortCharacter is failable, so it no-ops for an agent with no fort_character.

Eliminates all creatures spawned by this spawner.

Ends the NPC conversation for the agent.

Checks if 1 or fewer players remain. If so, declares the last player as winner and ends the game. Does nothing otherwise.

Modifier: executes subsequent actions for every player matching a variable condition. Example: eliminate all players where is_safe == 0.

Spawns the sentry at its device location.

Spawns a supply drop from the spawner.
