+title: An introduction to Entity–component–systems
+updated: 2020-6-8
+---
+
+Recently, I created the fourth version of my game GetSquared. GetSquared is a game I have been working on and off of for the past 3 years, with this being it's fourth finished version, seventh attempt. 
+Before this all of the other versions had online networking, but that was proving to be a real challenge, so for this version it was local single player only. 
+
+GetSquared version four was created using the Entity–component–system archecture.
+The short and simple explaination is that ECS is an archecture in which the game entities are just UUIDs which get assigned to systems. 
+For instance "player" entity would get the Velocity system, MarkerSummoner, CharacterController2D system, etc.
+Each system is meant to handle one thing in the game.
+For instance the MarkerSummoner system handles summoning a marker when the user presses `space` to summon one, and the CharacterController2D handles converting player key presses into momentum to be applied to their velocity. 
+The velocity system turns uses the player's velocity to change the current position of the player.
