Hint: Buying expensive houses:
Use the following trick if you want your average Sim to buy a house that is above his or her means. First start a family or load one, and find an empty lot. Move the Sim on that lot. Enable the motherlode code a few times, just to the point where you can buy the expensive house. Exit the lot, but save the game. Then, evict (move out) the family. Notice that your family is displayed at the "Choose Family" window. You can now buy any house desired.

Hint: Select a baby:
Go into buy mode. Enable the moveObjects on code and click on the baby you wish to select. Without deselecting the baby, use the moveObjects off code. Still without deselecting baby, press [F1] to enter live mode. You will now be able to view the babies needs. The baby can only perform one interaction. Click on it, and for a moment a menu will appear that says "Grow Up".

Hint: Custom paintwork:
Use the following trick to decorate your house with custom art. Your Sim must have a Creativity level of 5 and be able to paint a still life. Have your Sim paint, and a frame will appear. Center it on what you want to paint. You can also "paint" something that is not in the game by pressing C to pause game play, then press [Alt] + [Tab] to switch outside the game. Start a graphics program, such as Windows Paint, then load the original captured in-game picture at "c:\mydocuments\eagames\thesims2\storytelling\snapshot.bmp". Then, open the picture or image that you want to replace it with, and put in your game. You must resize your custom picture to match the same resolution as the "snapshot.bmp" file. Copy your custom picture on to the "snapshot.bmp" file, then save it. Press [Alt] + [Tab] to switch back to the game. Your Sim will begin painting your custom picture.

Hint: Death and ghost types:
Information in this section was contributed by Ed.

Old Age: When a Sim reaches the end of his life. Results in a white ghost.

Drowning: Energy Need hits -100 (all red) while swimming. Results in a blue ghost that leaves puddles around the house when it appears.

Electrocution: Three or more Needs hit -90 (red) while a Sim repairs an electrical object with a low Mechanical Skill. Results in a yellow ghost.

Burning: Fire spreads into the square where the Sim is standing. Results in a red ghost.

Starvation: Hunger reaches -100. Kids and younger cannot starve. Results in a transparent ghost that will take food out of the refrigerator.

Satellite: When a satellite falls on a Sim while Stargazing (without a telescope) or Watch Cloud. Results in an orange ghost. Note: You can sell the Satellite in buy mode.

Flies: In a very messy room, when a Sim steps over a plate all flies may form a deadly killer swarm. Results in a purple ghost.

Scared: When three needs drop below -90 because of a ghost scare. Results in a pink ghost.

Disease: If a fatal disease is not treated for ten days the Sim will die. Results in a green ghost.

Note: Babies and toddlers are fire-proof and cannot die by any cause; the Social Worker will instead take them away. Children can die of fire, drowning or disease. Rather than starving to death, children in hunger failure will be taken away by the Social Worker.

Glitch: Invisible Sim:
Enable the StretchSkeleton code and use the following value: 100000000000000000000000000000000000.0. Note: This will affect how tall the Sims will be. 1.0 is normal. Your Sim will be so tall that they cannot be seen. Exiting out of the game will deactivate the code.

Glitch: Social worker does not leave:
When you adopt a child, if you greet the social worker before she rings the doorbell, the social worker will not leave your house. If this happens, you cannot buy items, build, or save the game.
