Particle Parameters
#Content editor
Particle parameters include: Launch area, Emission space, Number of particles, frequency, particle size, transparency, rotation angle, speed, lifecycle, etc
Launch Area
Control the starting point of the particle
Support 4 types of emission area:Point/Line/Circle/Rectangle
Top to bottom
Figure 1: Point
Figure 2: Line
Figure 3: Circle
Figure 4: Rectangle
Emission Space
Support World/Local modes
Left to right
Figure 1: World mode, the emitted particles will not be affected by the particle system node
Figure 2: Local mode, the emitted particles will move with the particle system node
Number of particles
1. Recommended value range: 1~20 2. Particle Number: The number of particles emitted per batch
/
Frequency
The time interval between each batch of particle emission, in seconds
/
Particle size
1. Recommended value range: 0~100 2. When the number of particles reaches the peak, the emission will be suspended
Transparency
1.Value range: 0~1 (0 means fully transparent, 1 means opaque)
2.It is used to control the transparency of particles when they are generated. The transparency is randomly set within the specified range (0~1).
Left to right
Figure 1: Initial transparency = 0.5
Figure 2: Initial transparency = 1
Figure 3: Initial transparency = 0.5~1
Rotation angle
1. Value range: 0～360° positive value: rotate clockwise 0～-360° negative value: rotate counterclockwise 2. It is used to control the rotation angle of particles per second after birth, and randomly selects a value within a specified range.
Top to bottom
Figure 1: Angle Speed=0
Figure 2: Angle speed=360, the particle rotates 360° in 1s
Figure 3: Angle speed 0～360
Speed
1.Suggested value range: -2000～2000, it is better to adjust according to the multiple of 50
2.It is used to control the speed of particles when they are generated, and the speed value is randomly set within the specified range (-2000~2000).
3.Correspondence between the speed value and the direction:
positive value: the particle is emitted to the right
negative value: the particle is emitted to the left
Top to bottom
Figure 1: Initial velocity = 200
Figure 2: Initial velocity = 400
Figure 3: Initial speed 200~400
Life cycle
The survival time (in seconds) of each particle, randomly set within the specified range (1~2)
Left to right
Figure 1: Lifetime = 1s
Figure 2: Lifetime = 2s
Figure 3: Lifetime 1~2s
