Doors, movers and buttons

These are brush entities. They are AnimatableBody3D nodes, so they carry whatever stands on them.

Note: Doors and buttons do not react to the player on their own. Your player script calls use(activator) on them, see Button opens a door. Set interact to 0 for one that should only move from I/O or a script.

func_door

Slides by travel when opened. wait -1 stays open, a positive value closes it again after that many seconds. A locked door ignores open and use and fires locked_use instead.

• Inputs: open, close, toggle, lock, unlock, use(activator)
• Outputs: opened, closed, started_opening, started_closing, locked_use(activator)
• Keys: travel 0 64 0, speed 2.0, wait -1, locked 0, start_open 0, interact 1

func_door_rotating

Swings around a hinge, which you drag into place in the viewport. open_away swings it away from whoever opens it, which is why open takes the activator here.

• Inputs: open(activator), close, toggle(activator), lock, unlock, use(activator)
• Outputs: same as func_door
• Keys: hinge 0 0 0 (relative to the door's center), axis y, open_angle 95 (negative swings the other way), speed 120 (degrees per second), open_away 1, wait -1, locked 0, start_open 0, interact 1

func_gate is an older alias with only hinge, open_angle 100 and speed 90 as keys. Use func_door_rotating.

func_platform

A lift or moving platform between its start and start + travel.

• Inputs: start, stop, toggle, go_to_end, go_to_start
• Outputs: reached_end, reached_start, started
• Keys: travel 0 128 0, speed 2.0, wait 1.0, mode 0, start_active 0

func_train

Follows a chain of path_corner entities, starting at target. It moves from map load and loops, so set start_active or loop to 0 for a one off ride. Each corner's wait and speed apply on arrival.

• Inputs: start, stop, toggle
• Outputs: arrived(corner), finished (only when not looping)
• Keys: target, speed 3.0, loop 1, start_active 1, orient 0 (1 turns it to face where it goes)

func_button

Moves by travel while pressed and fires pressed. It pops out again after wait seconds, -1 keeps it pressed.

• Inputs: press(activator), release, lock, unlock, use(activator)
• Outputs: pressed(activator), released, locked_use(activator)
• Keys: travel 0 -2 0, wait 1.0, locked 0, interact 1
