The GravityWell action applies a force on the particle to draw it towards, or repel it from, a single point.
The force applied is inversely proportional to the square of the distance from the particle to the point, in accordance with Newton's law of gravity.
This simulates the effect of gravity over large distances (as between planets, for example).
Constructor:
new GravityWell([x], [y], [power], [epsilon], [gravity])
Parameters:
| name | type | arguments | Default | description |
|---|---|---|---|---|
| x | number | Phaser.Types.GameObjects.Particles.GravityWellConfig | <optional> | 0 |
The x coordinate of the Gravity Well, in world space. |
| y | number | <optional> | 0 |
The y coordinate of the Gravity Well, in world space. |
| power | number | <optional> | 0 |
The strength of the gravity force - larger numbers produce a stronger force. |
