Configure a Player to simulate different network connections example

The logic in the following example checks if the tag has a string rather than if it’s equal to a string to allow for more flexibility with the name of the tag. You can change this logic so that it checks for an exact match.

Simulate network conditions

This example script uses the Network Simulation Presets from the Multiplayer Tools package to automatically simulate a fast or slow network based on the tag. A Player with the FastNetwork tag simulates a common Home Broadband connection, and a Player with the SlowNetwork tag simulates a Mobile 2.5G connection.

Note This example uses the Network Simulator tool from the com.unity.multiplayer.tools package.
