Move Object around a platform of tiles
I want to make a spinning spike to move around a platform made out of tiles like in the following picture. 
I have written every possible state on where to move when platform tiles block the spike's way. It would look like this
for (int i = 0; i < platformTileMap.Length; i++)
{
if (platformTileMap[i].HasTile(cellPosition + new Vector3Int(0, -1, 0))) // BOTTOM
{
moveX = moveDir;
}
else if (platformTileMap[i].HasTile(cellPosition + new Vector3Int(0, 1, 0))) // TOP
{
moveX = -moveDir;
}
else if (platformTileMap[i].HasTile(cellPosition + new Vector3Int(-1, -1, 0))) //BOT LEFT
{
if (moveDir == 1)
{
moveY = -1;
}
else moveX = moveDir;
}
else if (platformTileMap[i].HasTile(cellPosition + new Vector3Int(1, 1, 0))) //TOP RIGHT
{
if (moveDir == 1)
{
moveY = 1;
}
else moveX = -moveDir;
}
else if (platformTileMap[i].HasTile(cellPosition + new Vector3Int(1, -1, 0))) // BOT RIGHT
{
if (moveDir == 1)
{
moveX = moveDir;
}
else
{
moveY = -1;
}
}
else if (platformTileMap[i].HasTile(cellPosition + new Vector3Int(-1, 1, 0))) // TOP LEFT
{
if (moveDir == -1)
{
moveY = 1;
}
else
{
moveX = -moveDir;
}
}
I feel like there has to be a more efficient way to solve this right? Or do i really have to write every possibility in if statements.
