The OR Gate is a simple logic gadget that activates when one or more of its inputs are active. By default it only has two ports, but can be can be changed to have more.

Signal Behaviour

Digital

Input 1	Input 2	Input 3	Output

When any of its inputs receives a digital ON signal, the OR Gate passes it through its output. The table on the left shows how a 3-port OR Gate reacts to specific input combinations.

Analogue (Maximum Input)

Input 1	Input 2	Input 3	Output
30%	40%	50%	50%
10%	40%	-20%	40%
40%	40%	-50%	-50%
50%	-50%	-50%	50%
-50%	50%	50%	-50%

The OR Gate has two modes for handling analogue signals. By default it outputs the strongest analogue signal it receives from any of its inputs, be it Positive or Negative. If two or more of its inputs tie for the strongest signal and both are in opposite directions, the direction from the topmost port is used.

Analogue (Add Inputs)

Input 1	Input 2	Input 3	Output
30%	40%	30%	100%
100%	-50%	-25%	25%
30%	40%	30%	100%
100%	-100%	-100%	-100%
50%	50%	50%	100%

In LittleBigPlanet PS Vita, the OR Gate has an alternate output mode where, instead of outputting the strongest signal, the signals from all of its inputs are added together. Positive signals add to the combined strength, while Negative signals subtract from it. It should be noted that the OR Gate's signal strength is capped and cannot go higher than 100%, nor lower than -100%.

This output mode was brought over to LittleBigPlanet 2 in Game Update 1.28, and was carried forward to LittleBigPlanet 3.

Tweaks

Number of Ports: (2 - 100) Changes how many inputs the OR Gate has.

Output

Invert Output: ( No •‎ Yes ) Inverts the gadget's output, turning On signals Off and vice-versa.

Output Value: ( Maximum Input •‎ Add Inputs ) Sets which kind of analogue signal the OR Gate outputs. Maximum Input The OR Gate outputs the signal from whichever of its inputs receives the strongest signal — either Positive or Negative. Add Inputs The OR Gate outputs the combined signal strength of all its inputs, e.g. 30% + 30% = 60%. Note that the signal strength cannot go higher than 100%, or lower than -100%.

Visible in Play Mode: ( No •‎ Yes ) Determines whether or not the object will be rendered in Play Mode.

Bugs

Out of Bounds

When the signal adding function was added it introduced some bugs in relation to signal strength; initally, signals added together could exceed the maximum float value (100% signal), but this was fixed in a patch.

After it was fixed, it's still possible to exceed the signal limit with addition if a signal already outside of the range is plugged into the inputs.
