Logic

Logic entities are points with no body and no visuals. They shape the flow of signals. For entities that run code or drive animations, see Scripts and calls.

logic_relay

Forwards whatever triggers it and can be switched off, the easiest way to make a chain that only works under some condition.

• Inputs: trigger(activator), enable, disable, toggle
• Outputs: triggered(activator)
• Keys: start_disabled 0

logic_branch

Remembers true or false and fires one of two outputs when tested, for checks like "only if the power is on".

• Inputs: set_true, set_false, toggle, test, set_and_test(value)
• Outputs: on_true, on_false
• Keys: start_value 0

logic_counter

Counts between min and max, for "press all three buttons" puzzles. The value is clamped and nothing fires unless it changes. hit_max and hit_min fire when a change lands on a limit, reset fires only changed.

• Inputs: add(amount) (1 by default), subtract(amount), set_value(value), reset
• Outputs: hit_max, hit_min, changed(value)
• Keys: min 0, max 3, start_value 0

logic_timer

Fires timer every interval seconds from map load, unless start_on is 0. With random_max above random_min each wait is random in that range. once stops it after the first firing.

• Inputs: start, stop, toggle, fire (once, now)
• Outputs: timer
• Keys: interval 1.0, random_min 0, random_max 0, start_on 1, once 0

logic_auto

Fires map_spawn once, after every entity of the map is ready. Start anything that runs from the beginning here.

• Outputs: map_spawn

logic_sequence

A timeline for cutscenes. It fires up to eight numbered steps in order, waiting before each one, the first included.

• Inputs: start, stop, reset
• Outputs: step_1 to step_8, step(index), finished
• Keys: steps 3 (1 to 8), interval 1.0, times empty, start_active 0, loop 0

times is a space separated list of waits, one per step, and steps without an entry use interval. With loop on it starts over and never fires finished. start is ignored while it runs, and stop then start begins again from step 1. See the cutscene tutorial.
