Vulture Aid createFontString(font, fontScale), setPoint(point, relativePoint, x, y).
font has a few different options like "default", and "objective". fontScale is self explanatory, it's the scale of the font lol.
point and relativePoint are a bit different though. There's "CENTER", "TOP", "BOTTOM", "LEFT", "RIGHT", "TOPRIGHT", "TOP_RIGHT", "TOPLEFT", "TOP_LEFT", "TOPCENTER", "BOTTOM RIGHT", "BOTTOM_RIGHT", "BOTTOM LEFT", "BOTTOM_LEFT".
You can kind of think of these as anchors. If I made a HUD with points "RIGHT", "RIGHT" and I appended text to it constantly, the HUD would grow to the left to maintain its position on the right.
