Particle Playground Grid (PB only)The Grid creates a continuous plane of particles from a set of grid intersections. Grid particles are created without any velocity, so the movement of Grid particles is completely determined by the Gravity, Repel, Wall, and Property Mapper settings. By default, Grid particles fall toward the bottom of the frame because by default the Force property of Gravity is on. With the Grid, a new particle appears on every frame at each grid intersection. You can't adjust this frequency, but if you want the grid to stop generating particles at specific times, set the Particle Radius/Font Size option to 0, or use keyframes to animate the value of the Particles Across and Particles Down properties. To make more particles appear each frame, increase the values for Particles Across and Particles Down. Note: By default, the Cannon is on and the Grid is off. If you are using the Grid and want to stop the Cannon from generating particles, turn off the Cannon by setting its Particles Per Second to 0 (zero). When creating particles using the Grid, adjust the following: Position Determines the X, Y coordinates of the grid center. When a grid particle is created, it is centered over its grid intersection, regardless of whether it is a dot, a layer, or a text character. If you're using text characters as particles, the Use Grid option in the Edit Grid Text dialog box (see Replacing default particles with text (PB only)) is on by default, placing each character on its own grid intersection, so normal character spacing, word spacing, and kerning do not apply. If you want text characters to appear at the grid position with normal spacing, use a text alignment other than the Use Grid option. Width/Height Horizontal and vertical dimensions of the grid, in pixels. Particles Across/Particles Down Number of particles to distribute horizontally and vertically across grid area. Particles are generated only when the value is 1 or more. Note: If the Width, Height, Particles Across, and Particles Down options are not available, the Use Grid option has been turned off in the Edit Grid Text dialog box. For more information, see Replacing default particles with text (PB only). Color Sets the color of dots or text characters. This setting has no effect if you use a layer as the particle source. Particle Radius/Font Size Sets the radius of dots in pixels or the size of text characters in points. (See Replacing default particles with text (PB only).) This setting has no effect if you use a layer as the particle source. To turn off the grid:
