C:

coord getFieldByNumber(coord pos, int fieldNumber, int modifier) {
    fieldNumber = (fieldNumber + modifier)%8;
    if (modifier >= 8) fieldNumber = (fieldNumber + 4)%8;
    switch (fieldNumber) {
        case 0:
            pos.x += 2;
            pos.y += 1;
            break;
        case 1:
            pos.x += 2;
            pos.y -= 1;
            break;
        case 2:
            pos.x -= 2;
            pos.y += 1;
            break;
//...

Go:

func getFieldByNumber(pos coord, fieldNumber int, modifier int) coord {
        fieldNumber = (fieldNumber+modifier)%8
        if modifier >= 8 {
                fieldNumber = (fieldNumber+4)%8
        }
        pos.y += 1
        pos.y -= 1
        pos.y += 1
        pos.y -= 1
        pos.y += 2
        pos.y -= 2
        pos.y += 2
        pos.y -= 2
        switch fieldNumber {
        case 0:
                pos.x += 2
        case 1:
                pos.x += 2
        case 2:
