Diagonal movement in square grid

In a grid graph with 8 directions, diagonal movement across nodes seems to have the same cost as lateral.Shouldn’t it be the square of 2, or to simplify for the user, 1.5 times?

Any suggestions on where I should look to implement this myself?

Hi

Diagonal movement doesn’t have the same cost as moving in the 4 axis aligned directions. It should be a close approximation to sqrt(2) times the normal movement cost.
Is there any case where this doesn’t seem to work for you? (screenshot?)
