Like other affectors, Attractor has the standard properties x, y, width, and height that represent the affected area. The size and position of the Attractor item determine the affected particles.
The size of the attracting point is always 0x0, and its location is specified by pointX and pointY 特性。
|
affectedParameter : enumeration |
The attribute of particles that is directly affected.
| 常量 | 描述 |
|---|---|
Attractor.Position
|
Position |
Attractor.Velocity
|
Velocity |
Attractor.Acceleration
|
Acceleration |
|
pointX : real |
The x coordinate of the attracting point, relative to the x coordinate of the Attractor item.
|
pointY : real |
The y coordinate of the attracting point, relative to the y coordinate of the Attractor item.
|
proportionalToDistance : enumeration |
The relation between the strength of the attraction and the distance from the particle to the attracting point.
| 常量 | 描述 |
|---|---|
Attractor.Constant

常量 |
Attractor.Linear
|
Linear |
Attractor.InverseLinear
|
Inverse linear |
Attractor.Quadratic
|
Quadratic |
Attractor.InverseQuadratic
|
Inverse quadratic |
|
strength : real |
The pull, in units per second, to be exerted on an item one pixel away.
Strength, together with the value of proportionalToDistance property, determine the exact amount of pull exerted on particles at a distance.
