water

Since 0.6

A bounded body of water (lake, pond): level from the entity's height, a box or ellipse outline, flat or small waves, its own look.

Bodies with buoyancy float on it. The highest level wins where bodies overlap.

Use it in a scene entity's components list as { "type": "water", … }. The contract writes the fields flat and refuses unknown keys.

Fields

Field	Type	Required	Default	Allowed values	Description
`size`	`Vec2`	yes			Full extent along the entity's own x and z axes before its scale, metres; both finite and above 0 (`water-shape-invalid`).
`shape`	`WaterShape`	no		`box`, `ellipse`	"box" (default) or "ellipse" (inscribed in the box).
`windMps`	`number`	no			Wind over the lake, m/s, 0..30. 0 (default) is flat water. Above 0 the lake has small waves: a fetch-limited wind sea whose fetch is the lake's longer side, so a bigger lake makes bigger waves (`water-waves-invalid` outside 0..30).
`windDirectionRad`	`number`	no	`0`		Compass bearing the wind blows toward, radians, as `sky.clouds.windDirectionRad`: 0 toward -Z, increasing toward +X. Default 0.
`seed`	`number`	no	`1`		Wave pattern, a whole number from 0. Same seed and time, same water, bit for bit. Default 1.
`priority`	`number`	no	`0`		Breaks a tie between overlapping bodies at the same level: the higher wins. A whole number -100..100. Default 0.
`look`	`LakeLook`	no			How the water looks (water type, foam). Render only. Absent: clear fresh water (`alpine-clear`); set a sea class for sea water.
