Hi, thanks for the quick reply.
When using “engine->toString()” it does print out my two inputs, output, and all its proportions as well as my Rule Block. But no matter what I do, I can’t seem to get my output based on mt data input or defuzzify it.
Any help is appreciated.
Here is my code if that helps at all
int main(int argc, char* argv[]) {
using namespace fl;
Engine* engine = new Engine;
engine->setName("CAR_AI");
engine->setDescription("");
InputVariable* DistanceVariableInput = new InputVariable;
DistanceVariableInput->setName("DistanceVariableInput");
DistanceVariableInput->setDescription("");
DistanceVariableInput->setEnabled(true);
DistanceVariableInput->setRange(-1.000, 1.000);
DistanceVariableInput->setLockValueInRange(false);
DistanceVariableInput->addTerm(new Trapezoid("FarLeftOfLine", -1.000, -1.000, -0.900, -0.600));
DistanceVariableInput->addTerm(new Trapezoid("LeftOfLine", -0.900, -0.600, -0.400, -0.100));
DistanceVariableInput->addTerm(new Triangle("OnLine", -0.100, 0.000, 0.100));
