=== What it's doing ===
|
|
Below will show you the calculations it's doing to modify the screen's position to emulate an earthquake or just a shiver or shake.

|
=== Note ===
|
|
For shake type four it checks the yCameraCurve to make sure it's not out of bounds:
|
|
{| border=2
|
|
|-
|
|
|if (yCameraCurve < 128) then yCameraCurve = 128
|
|
|-
|
|
|if (yCameraCurve > 383) then yCameraCurve = 383
|
|
|-
|
|
|} |
