Just a prototype idea that I briefly showcased in this video
You can drag around the particle emitter and the grass will automatically reposition in real-time if you have local_coords disabled on the emitter.
Made of 2 shaders, a particle shader and a fragment+vertex shader
- Places grass instances in a grid using their
INDEX - Spaces them according to
spacinguniform - Passes the world position of the particle to the fragment+vertex shader
- Calculates a circle around the player position
- Stomp animation for anything within that circle
- Kinda fades it towards the edges of the circle
- Rotates the vertices according to the wind
- Uses the world position to select a random sprite from a spritesheet
- Colors the top and bottom of the grass
