Building something similar to Minecraft
Based on Sable Spirit Studio's YT series
+
+
+## Notes
+
+My code tends to diverge quite heavily at times as I worked out better methods of performing certain actions.
+
+For instance, he went through a lot of work creating collision shapes for each block face and then using that to determine what face the player was looking at. However, I found the following basically removed any need for such complicated collision shapes and code:
+
+```
+EntityManager.create_block.emit("001", collider.position + get_collision_normal())
+```
+
+1 line of code replaced a very large amount of code and changes that were implemented in his `Create Blocks` video.
