Please implement Short-Circuit evaluation for Blueprint

[anonymous_user_566478b0]

I think people don’t understand very well what is happening there… Here is probably best example in pseudo code:

bool function A() { print(“Function A Called”); return false; }
bool function B() { print(“Function B Called”); return true; }

function TestShortCircuit()
{
if( A() && B() )
{ print(“Condition is true”); }
else
{ print(“Condition is false”); }
}

When you call function TestShortCircuit in C++ your output log will be:

Function A Called
Condition is false

When you construct same condition using blueprint node your log will be:

Function A Called
Function B Called
COndition is false

because blueprint is probably not wise enough to detect that condition can never be true when first function (A) returned false.

I belive it is “by design” because Epic doesn’t like forcing people to take care of order of input pins for pure functions… But yes, some AND node with Short Circuit implemented will make conditions nicer and life will be easier!
