Sulfur Cube Steering

Makes Sulfur Cubes steer the way their knockback direction suggests: the push is rotated relative to the shot instead of being applied straight along the projectile's velocity, so aiming at the side of a cube (for example while driving an ice boat) turns it.

How it works

SulfurCube#knockback only ever sees the projectile's velocity, so hitting the left or right edge of the hitbox produced the same push. This mod mixins the horizontal knockback angle:

• The reference direction is always the incoming direction (projectile velocity, or the attacker's look vector for melee).
• The deflection is derived from how far the aim line passes from the cube's center: ratio = perpendicular distance / half-width in that direction (0 = aimed at the center, 1 = grazing an edge).
• The deflection angle follows a logarithmic curve and is applied as a rotation of the incoming direction, capped at 85°, so the cube can never be pushed back toward the attacker.
• The knockback magnitude is scaled by 1 / cos(θ), so the component along the original heading stays unchanged and only the lateral component grows.
• No hit point is read, so far-side / overshoot hits cannot flip the direction.
