General #
Signals are carriers and transmitters of values. Objects connected to a signal can send an updated version of a value. For example, a slider connected to a sending signal will send a decimal number between 0 and 1 every time it is dragged. Another object, for example a display, can receive this signal to show the value on a screen.
A signal’s value can also be set in the logic editor, and nodes of the logic editor can react to changes in a signal’s value.
Properties #
Start Value #
Every signal has a start value, that is set when the location is loaded in Portal Hopper.
Always Inform #
If “always inform” is set to true, receivers of the signal always detect an updated signal value, even when the new value is the same as the old one.
If “always inform is set to false, receivers of the signal only detect an updated signal value, if the the new value is different from the old one.
Signal Types #
True/False (Boolean) #
Signals of this type can only take two values: true and false. A typical use case of true/false signals are buttons.
1 2 3 (Integer) #
Signals of this type can take any integer number, also negative ones.
3.141 (Float) #
Signals of this type can take any decimal number, also negative ones.
Text (String) #
Signals of this type can take text as value. The information is stored as a string, meaning any combination of characters that C# strings support can be the value of a text signal.
Object #
An object signal’s value can be any object in the location. Typical use cases of object signals are trigger zones and snap fields.
