How are ordinances created?

[Fatherted 129]

I would like to replace the Carpool Ordinance with a Martial Law Ordinance removing crime but creating civil unrest and riots. I would like it to take about 1/20 of income, and decrease crime to practically 0, but create riots outside civil buildings and lower mayor rating. I would also like to increase the flammability ratio due to arson. How would I do this? Is there a tutorial?

If possible I would like it to produce military Automata. Is that possible?

You should visit the omnibus section sometime. It has a lot of good tutorials... including one called Modding: Basic And Advanced Tutorials Lesson 1 is about creating ordinances The principle should be the same for any kind of ordinance

Start with the original Carpool Ordinance's exemplar to start with, then look at the other ordinances to see which properties are known to work.

You can apply a -100% crime modifier (The necessary property is in the Junior Sports Program exemplar), but it won't eradicate crime (It's not possible in the game's engine).

You cannot take a percentage of overall income, only according to the funding of a department (as per the Junior Sports (parks), Free clinics (health) and Pro Reading (education) ordinances), according to your population (as per a multitude of other Ordinances) or a static amount.

You can't cause riots directly. Lowering the Mayor Rating by a significant amount should trigger Riots, though you probably shouldn't lower the Mayor Rating to 0 (As in the very lowest it can be) in the event it overflows and goes to an obscenely positive value. It'd require research on your part as to how the game behaves when docking mayor rating points when there aren't enough to begin with (Reducing it by more than 150 in a new city should allow you to observe its behaviour).

You can look at the properties that the game implements in the default ordinances and their effects on the SC4DWiki's ordinances page.
