Building a Castle in the Clouds

Large second - floor extensions to a house, or even an entire house in the air, can be built totally unsupported by the following method. First, lay out a complete ground layer of pillars. You`ll need lots to form a surface to build on. Next build your second-floor home on top of these pillars. It`s important that you do ALL the structural work at this point; get all the walls placed and floors put in. Don`t forget the stairs! Next, simply switch to the ground floor, and delete all the pillars. The house will remain standing, completely unsupported by anything except thin air! Voila! A castle in the clouds for your Sims!

Garbage Bag of Holding

In the early stages of The Sims life time is often wasted emptying the trash and bringing it to the curb. I found that if you fill the cheap 30 simolian trash barrel you can order your sim to empty it and just as they remove the bag cancel the order. Then order them to pick up the mess that they just made and they will return the full bag to an empty barrel, which will now be empty. Do this every time it fills and trash need never be brought outside to the curb again. This saves a lot of time.

Paying the Bills

Simply keep a bill, unpaid, until the mail carrier delivers the next set. When your flag is up (your mailbox being full of-- what else, more bills), pay the first one (i.e., bring it out to the mailbox.) When you do this, the newer bills disappear. Using this cheat, you will only have to pay every other bill, instead of every one.

Raise Sims Mood Bars

When using the move_object cheat you can restore your Sims mood bars by getting your Sim to sit in a chair, pausing the game and deleting the chair that your Sim is in. Your Sim will disappear. Unpause the game and click on your Sims face icon and your Sim will reappear with some restored bars.

Don`t Pay Bills:

If you don`t want to pay the bills all you have to do is go to `Buy mode` and then pick up the bills. Then move them to a place where they cannot be put down like a chair and then press `Escape`. the Bills will disappear and won`t need paying.

ROSEBUD- Money MONEY MONEY!!!
