// This script is attached to the watering can in Wangari's scene
// This script is keeping track of the Z axis of the watering can
// If there the watering can is tipped...
// Water comes out of the watering can


// Tips to selves:
// Don't use steam VR objects as colliders
// Child invisible sphere to right hand to use as collider

//TODO: water
//make splashy sounds
//make sure they don't collide with each other - do this by writing code to ignore if the prefab collides with its self

//TODO: seed becoming a tree
//Create a variable to keep track of how many water prefabs fall on seed
//Use this variable to control the header/time marker of the timeline
//Make the water fall more slowly somehow
//1. Use the Timeline to enable and disable assets over time. 
//2. Attach the timeline to the game object Seed. 
//3. Use a script to enable the timeline, which in code is called the PlayableDirector.
//4. use script to keep track of the head (time marker) in the (animation?) timeline as a variable that can increment the timeline
//5. and control the timescrubber variable based on how much water has been instantiated by the watering can/come out of the watering can.
//(To fade, we can slowly change things using lerp() = change X between A and B multiplied by time)
//(Do a coroutine that lasts a few seconds to pause on first seed asset)
