type: "guide_line"

A glowing dashed line along a parabolic arc between two anchors.

Fields

Every world overlay also accepts positions (static or entity-anchored), region or the pos_x/pos_y/pos_z params, plus the shared definition fields (duration, easing, loop, persistent, fade_ticks, sound).

Field	Type	Default	Meaning
width	float	0.15	Line thickness, blocks
dash_length	float	0.6	Dash length, blocks
gap	float	0.6	Gap between dashes, blocks
speed	float	2	Dash crawl speed along the line, blocks per second (negative = reverse)
arc	float	1.5	Bows the path up (+) or droops it (-) at the midpoint, blocks
red/green/blue	float	0.25 / 1 / 0.45	Line colour
through_blocks	float	0	1 = visible through walls
intensity	float	1 (fades to 0)	Line opacity
