A toy infection simulator. Try it here

I was looking for a reason to learn a new language. Dart seemed like a good choice. I've always wanted to write a zombie infection simulator, cause, why not? During the covid-19 lockdown, it seemed like things aligned.

This is not a proper infection simulator, and even does things wrong. I've always enjoyed discrete simulators and this is how I chose to implement this.

You are the health official for a town and recommend various mitigation strategies to attempt to control the spread of the infection. Like real life, you have no idea what the parameters of disease actually are. All you have is reported values, represented on the right hand side.

Your town has homes, businesses, schools, hospitals, and public meeting spaces. The maps are for visualization of infection spread, it doesn't realistically map a proper town's layout. This simulator makes not attempt to model other societal aspects such as finance, or civil unrest.

Things todo:

• business district
  • classes of businesses; restaurant, movie, stores, schools, medical
• sub-day simulation ("hours")
• play/pause buttons
• randomize buttons (random disease)
• mitigation policies
  • shelter in place
  • vaccination
  • public service (wash hands, don't cough, etc)
• local government
  • variable compliance with health officer
  • signage show the HO how govt is responding
• Entity extensions
  • factor for compliance with rules
  • age for age specific disease
  • go home at end of day
  • goto work during day
  • goto public places (restaurant, movie, etc) in eve
  • "occupation" to determine which business to visit
