The Screen Shake action shakes the view.
Duration
The amount of time (in seconds) to shake the screen. Generally, screen shakes are best when they are short.
Horizontal Amplitude
The horizontal size of the shake. How far the virtual camera should move horizontally during the shake.
Horizontal Frequency
The number of times the horizontal shake animation should repeat during the duration of the shake.
Horizontal Start Delay
The delay (in seconds) before the horizontal shake begins.
Vertical Amplitude
The vertical size of the shake. How far the virtual camera should move vertically during the shake.
Vertical Frequency
The number of times the vertical shake animation should repeat during the duration of the shake.
Vertical Start Delay
The delay (in seconds) before the vertical shake begins.
Pro Tip
This action can be used to create many different effects. A classic screen shake (such as from an explosion) would likely use both horizontal and vertical amplitude values of about 1/10th the height of the screen, with a frequency of around 10-20, and a very short duration. You can also create directional effects by using only horizontal or vertical shake, or by adjusting the relative amplitudes and frequencies.
