I am making a SIR model on scratch. It isn't fully made yet but I will release just to show Im alive. Am making a project after like a year :) I was on Python for that time. ! ONLY WORKS ON TURBO MODE! PRESS SHIFT + GREEN FLAG! ! Explanation because I think it deserves it: The dots are HUMANS. They walk around their AREA, the big circle. 200 of them spawn, and 1 of them is INFECTED, represented in RED. They walk around like normal, contacting other humans and sometimes infecting the BLUE dots, the susceptible ones. After a while, they have an 80 percent chance to be noticed and be QUARANTINED, in the small box. Most just comes back to the big circle, but there are some exceptions. -Some come back altough they are still RED, -Some come back after growing an IMMUNITY, represented in YELLOW, -Some die. :( Sometimes, the dots die of a NATURAL cause, which makes it so another person spawns blue. Same things happens to the ones to die while infected. The bottom graph is the amount of infected people.
