Water2D
com.zzamjak.water2d is an OpenUPM Unity package. Vertex-based 2D water simulation for Unity. Water2D renders in world space (MeshRenderer) and UIWater2D renders inside a UI Canvas (MaskableGraphic), both sharing one simulation core so behavior and values stay identical. The surface keeps rippling without any collision through an analytic ambient wave (stacked sines plus value noise) whose strength, frequency and randomness are exposed as numbers. Physics is opt-in: collision splash, buoyancy and pointer input are off by default and the collider is disabled while they all are, and the spring simulation only wakes on events and sleeps automatically once the surface settles. The underwater shader uses procedural caustics, refraction and foam with no texture fetch by default, keyword-stripped features and no branching, for a mobile-first cost profile. UIWater2D supports Mask, RectMask2D and CanvasGroup alpha through standard UGUI mechanisms.
