Particle - Layer

General​

  • Name：Particle layer name
  • Emission Area：
    • Point：Particles are emitted from a point, enable parameters (X, Y)
    • Rectangle：Particles are emitted from a random position inside a rectangle, enable parameters (X, Y, Width, Height)
    • Circle：Particles are emitted from a random position inside a circle, enable parameters (X, Y, Radius)
    • Screen Edge：Particles are emitted from the edge of the screen, the emission position is related to the initial movement angle, suitable for making weather effects
  • Emission Count：Stop emitting particles after the specified number of particles have been emitted. If set to 0, there is no limit to the number.
  • Initial Delay：Delay the time to emit particles.
  • Interval：The emission interval time of the particles.
  • Lifetime：The time from emission to destruction of the particle.
  • Lifetime Dev：Lifetime ± Lifetime time deviation (random) = Final lifetime
  • Fadeout：Time for particles to transition to transparency before destruction

Anchor​

  • Anchor X：Horizontal position of the particle connection point
  • Anchor Y：Vertical position of the particle connection point
  • Anchor Speed X：Change in "Anchor X" per second
  • Anchor Speed Y：Change in "Anchor Y" per second
tip

The anchor point (0, 0) is at the center of the particle

Movement​

  • Movement Angle：The angle of the initial speed of a particle
  • Movement Speed：The initial speed of a particle
  • Accel Angle：Change in "movement angle" per second
  • Accel：Change in "movement speed" per second

Rotation​

  • Rotation Angle：Initial angle of the particle
  • Angular Velocity：Change in "rotation angle" per second
  • Angular Accel：Change in "angular velocity" per second

Horizontal Rotation​

  • Radius：Amplitude of the particle moving left and right, used to simulate rotation around the Y-axis
  • Expansion Speed：Change in "radius" per second
  • Expansion Accel：Change in "expansion speed" per second
  • Rotation Angle：Angle from the Y axis to the current position of the particle after horizontal rotation, right = 0 degrees, clockwise rotation
  • Angular Velocity：Change in "rotation angle" per second
  • Angular Accel：Change in "angular velocity" per second

Scale​

  • Scale Factor：Scale factor for particle size, 1 = 100%.
  • Expansion Speed：Change in "scale factor" per second
  • Expansion Accel：Change in "expansion speed" per second

Rendering​

  • Image：Spritesheet Image file
  • Blend：Normal, Additive, Subtract
  • Light
    • Raw：Unaffected by light
    • Global Sampling：Sampling light from multiple pixel locations where the image is located to composite the final color
    • Ambient Light：Use the ambient light of the current scene to composite the final color.
  • Sort：
    • Youngest in Front：The newly generated particles are displayed in front of the old ones.
    • Oldest in Front：The old particles are displayed in front of the newly generated particles
    • By Scale Factor：Particles with larger scaling factors are displayed in front
  • Horizontal Frames：The number of horizontal frames of the spritesheet, randomly selected a column when generating particles
  • Vertical Frames：The number of vertical frames of the spritesheet, randomly selected a row when generating particles
  • Color Mode：
    • Fixed：Enable parameter (Color)
    • Random：Enable parameters (Color Min, Color Max)
    • Easing：Enable parameters (Color Easing, Color Start Min, Color Start Max, Color End Min, Color End Max)
    • Texture Sampling：Enable parameters (Tint - Red, Tint - Green, Tint - Blue, Tint - Grayscale)
