( YouTube Tutorial ) Multi-Conditional Booleans For Games

What are multi-conditional booleans?

Multi-Conditional booleans, as the name suggests, are bool values that can be true or false under multiple conditions. For example, in your game you might have conditions under which your player character is invincible. Let's consider two states: The player is invincible if they are equipped with a Shield or they are invincible for 5 seconds after they choose to Revive in the game.

What happens if you implement these with a single boolean?

Suppose you have a boolean called _invincible that is set to true or false depending on the current player state. Now the player dies in the game and chooses to Revive. You set the bool value to true. Now before 5 seconds elapse, the player equips the Shield. You again set the boolean to true (or you may check if it's already true and not set it to the same value). After 5 seconds of Revive elapse you set the boolean to false, and now we have a problem. The player is equipped with a Shield and is NOT invincible.

How do multi-conditional booleans help with this?

Multi-conditional boolean is a wrapper class, that uses bitwise operations to determine the final state of the boolean. We reserve bits of an integer, one for each condition under which the player can be invincible. In the example above, we will reserve the first bit for Revive and the second bit for Shield. We set the corresponding bit to '1' or '0' depending on if that particular condition is true or false. The multi-conditional boolean is false when all the bits are set to 0, i.e the integers value is 0. If it is greater than 0 then the multi-conditional boolean is true.

In the following tutorial, I show you how to implement multi-conditional booleans in your games using Unity and C#.
