Hi Tom! Thank you for your reply. I can see now tons of tutorials and examples around on 2D shapes. I guess I was just using the wrong keywords for my searches. Kinda embarassing... sorry about that. Anyway, I managed to create some 2d objects but I'm still struggling with creating a 2D circle for my halo. I could draw it by adding a lot of points to an array and then drawing using the LINE_LOOP primitive. The only problem is that even though I'm using a simple circle equation (x^2 + y^2 = radius^2) and adding a LOT of points, the circle is still a little squared. Also, I'm worried about the cost of solving the math involved. Do you think of a better way to draw it? Again, thank you for your assistance.
