These scenes use Flora's runtime APIs to interact with Terrain trees. ## Tree Effect Animates Terrain trees inside a sphere.
Tree Effect sample
### Scene Path `Terrain/Scenes/TreeEffectSample.unity` ### Demonstrates * Tree instance query by sphere * Local-to-world retrieval and update * Per-instance runtime animation without converting trees to scene objects ### APIs * `FindInstancesIntersectingSphereMatching(...)` * `GetInstanceLocalToWorlds(...)` * `UpdateInstanceLocalToWorlds(...)` * `FloraInstanceFilter.ByTrees()` ### Run 1. Open `TreeEffectSample` and press Play. 2. Confirm trees inside the sphere animate and recover after leaving it. ## Tree Wrecking Ball Disables impacted Terrain trees and spawns Rigidbody replacements.
Tree Wrecking Ball sample
### Scene Path `Terrain/Scenes/WreckingBallSample.unity` ### Demonstrates * Collision-region tree query * Instance enable/disable control * Runtime replacement with `GameObject` + `FloraInstanceRenderer` ### APIs * `FindInstancesIntersectingSphereMatching(...)` * `SetInstancesEnabled(...)` * `GetInstanceWorldTransform(...)` * `GetInstanceOwnerTerrain(...)` * `GetInstanceTerrainTreeIndex(...)` ### Run 1. Open `WreckingBallSample` and press Play. 2. Let wrecking ball collide with trees. 3. Confirm impacted Flora instances are hidden and replaced with Rigidbody objects.
