(Idea & script by Larrow)
Place two helper spheres called helper1 & helper2
Execute this:
ermagerd = [] spawn {
while {true} do {
sleep 0.03;
start = player modelToWorld [0,1,1.2];
end = player modelToWorld [0,3,1.2];
helper1 setPos start;
helper2 setPos end;
hintsilent str (lineIntersects [start,end,helper1,helper2]);
};
};
