## What is Bump Simulator?

BumpSim is a toy app to view computational spread of a theoretical contagion. 

Description of the user interface is as follows:
- Risk is an arbitrary measure of susceptibility per added node. Low slider means lower probability of passing an infection from infected to non-infected nodes. 
- Mortality is an arbitrary probability of death after the infection duration. Lower slider means lower probability of node death. 
- Duration is an arbitrary length of infection leading to either death or immunity. 
- Infected is a switch which adds an infected node if it is on. When off, the node is added without an infection. 
- Copy to Clipboard will copy two JSON arrays: one array with a list of all nodes attributes, and another array of all node events where a node bumps into another node.
- Each node can be tracked through their UUID.

To use the app, change the sliders and press the "Add Node" button. Please note that you must add at least one Infected node to see the simulated spread of contagion. 

Green Nodes are Healthy, Red Nodes are Infected, and Blue Nodes are Immune. If a node dies, it is removed.

## Key features

- Contagion spread simulation
- Adjustable risk, mortality, and duration
- Node tracking by UUID
- Visual representation of node states
- JSON data export
- Add infected or healthy nodes

## Frequently asked questions about Bump Simulator

### What is Bump Simulator?

Bump Simulator is a toy application designed to visualize the computational spread of a theoretical contagion. Users can adjust parameters like risk, mortality, and duration to observe how infections propagate through a network of nodes.

### How do I start a simulation in Bump Simulator?

To begin a simulation, adjust the sliders for Risk, Mortality, and Duration. Then, ensure the 'Infected' switch is on and press 'Add Node' to introduce an infected node. You must add at least one infected node to see the spread.

### What do the different node colors mean in Bump Simulator?

In Bump Simulator, Green Nodes represent Healthy individuals, Red Nodes are Infected, and Blue Nodes are Immune. Nodes that die are removed from the simulation.

### Can I export data from Bump Simulator?

Yes, Bump Simulator allows you to copy two JSON arrays to your clipboard. One array contains all node attributes, and the other lists all node events, such as when one node bumps into another.

### What devices is Bump Simulator available on?

Bump Simulator is available on iPhones, iPads, and iPods, as indicated by its supported devices list.

### What is the age rating for Bump Simulator?

Bump Simulator has an age rating of 4+, making it suitable for a wide range of users.
