2D流体

Simulation2D.cs

• 流体的边界用OnDrawGizmos设置流体的边界

    void OnDrawGizmos(){Gizmos.color = new Color(0, 1, 0, 0.4f);Gizmos.DrawWireCube(Vector2.zero, boundsSize);Gizmos.DrawWireCube(obstacleCentre, obstacleSize);if (Application.isPlaying){Vector2 mousePos = Camera.main.ScreenToWorldPoint(Input.mousePosition);bool isPullInteraction = Input.GetMouseButton(0);bool isPushInteraction = Input.GetMouseButton(1);bool isInteracting = isPullInteraction || isPushInteraction;if (isInteracting){Gizmos.color = isPullInteraction ? Color.green : Color.red;Gizmos.DrawWireSphere(mousePos, interactionRadius);}}}
