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);
            }
        }

    }
