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. <\/p>\n\n\n\n
A signal’s value can also be set in the logic editor<\/a>, and nodes of the logic editor can react to changes in a signal’s value.<\/p>\n\n\n\n Every signal has a start value, that is set when the location is loaded in Portal Hopper.<\/p>\n\n\n\n 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.<\/p>\n\n\n\n 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.<\/p>\n\n\n\n Signals of this type can only take two values: true and false. A typical use case of true\/false signals are buttons<\/a>.<\/p>\n\n\n\n Signals of this type can take any integer number, also negative ones. <\/p>\n\n\n\n Signals of this type can take any decimal number, also negative ones.<\/p>\n\n\n\n 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. <\/p>\n\n\n\n An object signal’s value can be any object in the location. Typical use cases of object signals are trigger zones<\/a> and snap fields<\/a>. <\/p>\n","protected":false},"excerpt":{"rendered":" General Signals are carriers and transmitters of values.
