hey guys today i'm back in polybridge and i wanted to try out a new challenge the idea is to beat the campaign using only one road per level now this won't be an exhaustive video since so many levels are fundamentally just the same so instead i found two levels that are similar but should still offer a unique challenge so let's turn into it so starting out with the first level in the game actually this is level one one and last time i played it was with my collab google civil engineer so i deleted that loaded up my budget solution and this is what i originally did to beat this level so it's very very simple courage has to go over to the other side but i'm only going to be using one road like i said so i'm starting by building a big truss now i want to have a swing mechanism on this truss but i run into a problem i'm already a hundred percent over budget now that doesn't sound that bad but actually without turning on limited budget mode which i'm gonna try not to do you can't do more than NUMBER_TOKEN budget so that means the maximum i have is twenty thousand dollars to get this car across using only one road that's gonna be quite challenging so start by building a different trust one that's a little bit more cost effective and i leave myself with NUMBER_TOKEN NUMBER_TOKEN to build these swings and to get the road and get a trigger mechanism in place so put down the road to start and i'm also putting in the swing arms now for this i'm just using a bunch of wood pieces and i'm just leaving them loose and you can see it swings the other side so this should work out now one thing i don't like about this though is that the wood pieces are very loose right now i have no real way of controlling them so what i'm going to do for that is turn them into rigid pieces just by bracing them together using a bunch of wood and once i did that you see it swings back and forth and it's totally rigid now so i'm already NUMBER_TOKEN over budget and that's really bad i have a lot more to add so what i'm gonna do is just try to shrink down the top of the arch i shaved off about two thousand dollars and i immediately needed that money to start working on the swing now what i'm doing here is building up some sort of mechanism to weigh down the swing so it biases it to move over to the right and i'm gonna need this so that once the car gets on it it'll get carried all the way over it doesn't just you know stop halfway there now for the weights what i need to do is make a long chain of wood now an interesting quirk about the game is that wood actually weighs nothing it's nodes that way stuff so building a long chain of nodes like this is going to be very heavy and having long pieces of wood actually would pretty much just do nothing except for the nodes on the end of them and with that done i want to start working on the triggering mechanism as well now the triggering mechanism is a little bit tough and i'm starting here just by going for something what i think is at least pretty simple is just having the road sit on the left island very very slightly and then once the
