Thanks Yal! The "layering" level 3D system is very clever. Regarding the positioning of the bullets - I got that eventually resolved on the GM forum, and you are right - it's very hard and I don't think I'm yet at the level to properly utilize them complex maths and matrices needed for what I'm trying to achieve. So I guess for now I'll just stick with the "gun at the center of the screen"
Cheers!

Sounds like a plan... it's always possible to change it later in case you get better at 3D maths later, and working with 3D is a good way to learn about 3D, I guess :P
IMO the hardest part is figuring out how 3D vectors work (which needs linear algebra so you can actually do math with them - but you need to learn visualizing them as well in order to figure out HOW to use them for any given problem), once you've got that part down you can solve more or less any problem by doodling down a few lines on paper and putting variable names at all angles and lengths you'll need to use in the game. Don't underestimate doodling on paper, it helps visualizing stuff MUCH better than the maths formulae on their own :3
