It is possible to complete the task by bringing just one cart by pushing it so that it passes over both the target squares.
A first idea would be to reset a cart on reaching the target spot. This would look a bit like the cart actually being brought into the barn.
The other idea would be to have distinct targets for each cart. But this would mean, that there is no flexibility with cart positioning: If spot A only accepts cart A, then you cannot bring cart B on it.
So I'd more go for the first option.
You seem to have CSS turned off.
Please don't fill out this field.
Third option would be placing a collision on the right side of the targets too. Then it would not be possible to move the carts once they're at either of the target squares.
Couldn't you just do a check to see if both spots are occupied when talking to Eheneumniranin? Not sure if this is feasible, I don't know how the points are set up.
That would not work when doing the quest in parts. The carts can be reseted in between.
Is there more than 1 part to the quest?
You have to bring 2 carts to two spots. Another option, maybe a bit more complicated, would be to have a check in the target spots that the other spot is also occupied at the same time. This would be the real trigger defining the quest is finished.
That has the same effect that it would not be possible to complete the task in parts. It could be confusing for a player that takes a cart to the barn, logs out for lunch, and returns to finish the quest (or even just loses the connection - that could reset the carts)
Is that bug fixed?
Fixed by resetting a Block when it reaches the target. This looks a bit like the hay cart being moved into the barn.
