Summary:
This example is for absolute beginners using GameMaker for the first time, and without any experience writing code.

The video discusses some basic ideas such as room origin and size, x and y axes, and how to move objects in the room. These ideas are explained using the basic movement code that is often used in other tutorials. The code is explained line-by-line at a very basic level.

Along the way, I talk about the idea of using events and code to check whether a key is pressed.

I made this tutorial because I found it difficult to follow tutorials where the fundamentals of coding were not explained, such as why type
x = x - 7? It felt like being told that 5 x 5 = 25 but not understanding that it means 5 sets of five things. Hopefully, this helps as it took me a while to find the answers.
