Is GB Studio more GUI-friendly than Game Maker Studio?
Cause Game Maker Studio pretty much requires you to use their scripting language to do anything, at which point you might as well be learning a real programming language..
I have not used Game Maker, but in GBStudio you pretty much drag and drop stuff. It's more or less like this.
Click on "+" to Create a new scene. You select what type of scene you want (Platform, Shooter or Pokemon/Zelda-like)
Then you draw on the scene or drag and drop the stuff you want to have on the scene.
When you are done, you draw a line from the scene to the next scene.
If you want to do more than the basic stuff, you select from many pre-made options, then you can drag and drop the order.
For example, you want to have your character shoot a projectile, you just click on "Add event" and select one from the list, such as "Joypad input" then add a "Launch projectile" event to that.
If you want more than that, version 2 has an option called "Eject" that will allow you to see the source code in C to modify and then continue editing it on GB Studio.
This channel has tutorials, most are for the the previous versions, but they still apply.
