Let's jump right into the action. At first, open "definition.txt" of your mod.
Now, there is only one section of interest: unit{ }


Your script will look different, since I already changed and added things.

The script for all of these utilities work the same.

Insert the following into the section satisfaction{ }:

{ #type utilities-modifier type utilpower value -1 }

So, what does that mean? You just defined that this tenant needs power, or electricity. Otherwise, this tenant's satisfaction will decrease by 1.
This is identical for all other utilities, just use:

• utilwater for water
  
• utilphone for phone
  
• utilcable for cable
  
• utilgas for gas

Of course, you can also adjust how much the satisfaction is affected when the need is not fullfilled. Therefore, just change the number after value from -1 to something else, e.g. 0.5. Make sure the use a dot instead of a comma (0,5)!


Alright, we are not done yet. There is a second step:

Insert the following into needutilities[ ]:

{ type utilpower value 1 }

This means, that there is a requirement of 1 electricity. You can change this to whatever you want, e.g. value 3.
Similar to before, just use:

• utilwater for water
  
• utilphone for phone
  
• utilcable for cable
  
• utilgas for gas

That's it. Great work.

That's it for now. I will add the needs for trash, recycling soon, as well as positive and negative influences of noise, traffic, smells, etc.

Stay tuned and leave a comment if you want :)
