📑 Core Scripts

• Grass Manager

The Grass Manager is responsible for managing all interactive grass elements in the scene. There is also global settings for the wind and recovery of the grass from interactions.

• Grass Interactor

The Grass Interactor is responsible for handling the interactions between the grass and other objects in the scene. It allows objects to affect the grass, bending and pushing it. You can have as many interactors in the scene, just make sure to add the Grass Interactor component to each.

• Mouse Interaction Handler

The Mouse Grass Interaction Handler provides data from the mouse position off the camera using a ray to allow an interactor to follow the mouse position and interact with the grass.

The Grass Animator allows for animation of the Grass Interactors set on a customizable path, similar to a spline. You can make it linear or curved, play once, loop or ping pong, set off unity events and more.
